Late binding on the other hand permits defining generic objects which may be bound to different objectsyou could declare myControl as Control without knowing which control you will encounter. You could then query the Controls collection and determine which control you are working on using the TypeOf method and branch to the section of your code that provides for that type
Eg : Dim ex as Object

set ex =CreateObject(“Excel.Application”)

1. What Is Vi?

VI is a Visual Editor (hence the name — vi for VIsual). What is a visual editor (as opposed to a non-visual one)? Visual editors are ones that let you see the document that you are editing as you edit it. This seems pretty common in most editors today, so the idea of a non-visual editor is a little strange. Examples of non-visual editors are sed, ex, ed, and edlin (the last one being the editor shipped with DOS until relatively recently.)

VI was written by William Joy as part of the bsd distribution of Unix. It was later used by AT&T, and has been standard Unix since.

2. What Is The Big Deal About Vi? Why Does Anyone Use It? More Importantly, Why Should *i* Use It?

vi is default visual editor under Unix, and is therefore shipped with all recent version of Unix. (Recent being defined as post 1984 or so.) This means that whenever you run across a machine that is running a Unix of some sort, you will know that you have a powerful editor at your finger tips. Why else? vi is a powerful editor. Also, once you know vi, you can edit files really quickly, as it is extremely economical with the keystrokes. Due to its different modes for inserting and issuing commands, it is much faster than most non-mode based editors. It is also a very small editor. (The version on my machine is 200k) Also, it can do almost anything, as long as you know how to get it to do what you want.

3. What Different Operating Systems Is Vi Available For?

Unix. That’s it. However, there are many, many clones of vi that are available for different operating systems. I personally have used vi clones under: Unix, Dos, OS/2, Mac System 7.

4. What Are Some Of The Vi Clones That Are Available?

• Just to list a few: STvi (STevie), elvis, vile, vim, and nvi, xvi.
• elvis is available for: Amiga, DOS, OS/2, Unix, VMS. 
• STevie is available for: Atari ST, DOS, Unix. 
• nvi is the vi that will ship with BSD 4.4. 
• vim is available for: Amiga, DOS, Mac System 7, Unix. Amiga, DOS, and the source are available at:
• ftp.fu-berlin.de /misc/editors/vim 
• vile is available for: DOS, OS/2, Unix, VMS. 
• xvi is available for: DOS, Unix.

There are some differences between the different vi clones. Many offer improvements, but most still allow the commands that are listed in this document, but there may be some differences. Refer to the documentation that comes with the clone for details.

5. What Games Will Help Me Learn Vi?

This may seem a bit silly, but there are many games on Unix systems that can help you learn to use vi. These help particularly with the basics. Although I don’t know of any games that help with every vi command, I do know of a few that will help you learn to use hjkl to move the cursor around. NetHack, a rouge-like game, is particularly good for this, as it is a large game and can be entertaining for quite some time. Not to make the other games sound worse, but some other ones are: rouge, moria, omega, worm, and snake.

6. What Is The Difference Between Command Mode & Insert Mode?

Often sited as one of the main problems with vi, and equally often sited as being one of its best strengths, vi differentiates between a “Command mode” and an “Insert mode.” Understanding this difference is VITAL to learning vi. When one starts vi it starts in command mode. In this mode, one can move around the file, and issue commands to change certain areas of the text, cut, copy and paste sections of the text and do much more. Insert mode is where one can actually insert text. In other words, command mode is used to move around the document, and insert mode is used to type text into the document.

Commands such as: a, i, c, C, O, o and others will switch one from command mode to insert mode.

or ^C will take one out of insert mode and return one to command mode.

Get used to this distinction. It is one of the things that makes vi different from most other editors. It also allows one to do a lot of things without taking one’s hands from the standard keyboard position.

7. How Do I Search For Text?

/ will search forward. ? will search backwards. ?? or // will repeat the last search. It is worth noting that these are pretty much standard in Unix. In addition, in vi, n will find the next occurrence. N will repeat the last search, reversing the direction. Regular Expressions may be used within searches.

8. How Do I Search For A Control Sequence?

/^V^

^V will tell vi to take the next character literally, and not to take it as a command.

9. How Do I Reformat Text?

If your computer has the program fmt on it, all you need to do is type !}fmt from insert mode. This will rejustify the text from the current location until the end of the paragraph. If your machine does not have fmt, you need to find a similar program. (I gather there are many such programs available from the public domain, but I do not know much about them.)

10. What’s The Deal With All Of These : Commands?

The commands that follow a : are commands from the ex editor. These allow a lot of flexibility and power. For example, there are many different ways to search and replace, all of with have some similarities.

11. How Do You Do A Search And Replace?

Well, there are a few methods. The simplest is:

:s/old/new/g But, this only does it on the current line… So:
:%s/old/new/g In general,
:[range]s/old/new/[cgi]

Where [range] is any line range, including numbers, $ (end of file), . (current location), % (current file), or just two numbers with a dash between them. (Or even: .,+5 to mean the next five lines). [cgi] is either c, g, i, or nothing. c tells vi to prompt you before the changes, g to change all of the occurrences on a line. i tells vi to be case insensitive on the search. No character after the last slash will only change the first occurrence on the line.

My favorite method is:

:g/foobar/s/bar/baz/g This searches for foobar, and changes it to foobaz. It will leave jailbars alone, which the other method will not. This is my favorite method, but is harder to remember. Of course you can also use regular expression search patterns, and a few other commands in the replacement part of the text. If you use ( and ) in the pattern to escape a sequence, you can do lots of nifty things.

For example:

:g/(foo)(bar)/s/2/1baz/g will change foobar for foobaz.

Special sequences allowed are:

& everything which was matched by the search

[1-9] The contents of the 1st-9th () pair
u The next character will be made uppercase
U The characters until e or E will be made uppercase
l The next character will be made lowercase
L The characters until e or E will be made lowercase
[eE] end the selection for making upper or lowercase

12. How Do I Run A Program From Within Vi?

:!cmd will run the program cmd. :sh will run an interactive shell. Within this shell, you may, if you want, run vi again. This is particularly useful when you are editing makefiles and config files for programs in an attempt to get a program to compile. The advantage over :e is that you do not need to save the file, and it will be in its old place when you exit the shell.

13. Any Tips For Making Vi Programmer Friendly?

:set ai will make it auto-indent for you.

:set sw=# where # is a number will set the shiftwidth (tabwidth).

You can then use <<, >> to shift a line left or right. Plus, you can use <% to shift a {, ( or [ set left or right (with >%). You must be on top of the specific {, }, (, ), [ or ] of the pair to shift them.

:set sm will show the matching {, ( or [ when you type the closing one.

:set lisp will make some changes that are useful for lisp programming. () will move back and forth over s-expressions, and {} will move without stopping at atoms.

14. How Do I Make A Function Key A Macro?

If is #n where n is 0-9, it will be mapped to the appropriate function key.

15. What Does The C$ Command Do From Command Mode Using Vi Editor?

c$ will begin from the character under the curser till the end of line. so when you use this command it will show you $ sign at the end of the line and you can change till that point.

16. How To Append A File To Current File Using Vi Editor?

22. What Is The Command Used To Append Text After Current Line In Vi Editor?

The command used to append text after current line in Vi Editor is

A

23. What Are The Different Modes In Vi Editor?

There are three basic modes of vi:

Command mode:
This is the default when you enter vi. In command mode, most letters, or short sequences of letters, that you type will be interpreted as commands, without explicitly pressing Enter . If you press Esc when you’re in command mode, your terminal will beep at you. This is a very good way to tell when you’re in command mode.

Insert mode:
In insert mode, whatever you type is inserted in the file at the cursor position. Type a (lowercase letter a, for append) to enter insert mode from command mode; press Esc to end insert mode, and return to command mode.

Line mode:
Use line mode to enter line oriented commands. To enter line mode from command mode, type a colon ( : ). Your cursor moves to the bottom of the screen, by a colon prompt. Type a line mode command, then press Enter. Any sensible command from the Unix line editor ex will work, and a few are good to know about. These commands are indicated in this handout by a colon in front of the command. Each time you use a line mode command, you must type a colon to enter line mode, then type the command by the colon prompt at the bottom of the screen, then press Enter when you finish typing the command. (The search commands starting with / and ? work similarly.

24. What Is The Difference Between Lettered Buffer And Temporary Buffer In Vi Editor?

Temporary Buffer: 
Deleted or copied text goes into a temporary unnamed buffer. The contents of the temporary buffer may be retrieved by using the p or P commands.

Lettered Buffers: 
There are 26 lettered buffers (a-z). Contents of a lettered buffer are saved until you copy or delete more characters into it, or until you quit your current vi session.

eg.

From Command Mode

“ayy Copy (yank) a line into buffer letter “a”

“ap Put contents of lettered buffer a below the current line

25. Which Command Is Used To Replace Many Characters In Vi Editor?

change command can be used to change a word/line.

cw change word forward
cb change word backward
c$ change from cursor to end of line
cL change from current line to and of screen
cG change from current line to and of file

or if you want to replace all occurence of some specific character

:%s/oldText/newText/g

26. Explain What Does The /text Command Do?

1. What Is Dns?

DNS stands for Domain Name System. It is a hierarchical system for identifying hosts on the Internet or on a private, corporate TCP/IP internetwork. It resolves the IP addresses to host names (or friendly internet names) and Host names to IP addresses.

2. What Is The Structure Of Dns?

The structure of DNS starts with root domain. Then it (root domain) braches to TOP level domains, then second level domains, and so on to the individual host names.

 Root Domain –> Top level Domains–> Second level Domains–> So on so forth up to individual host systems

3. How To Install Dns?

We can install DNS in 3 different ways:

• While installing Operating System: While installing Operating System, It asks at Network Settings whether you want Typical settings or Custom Settings. Select Custom Settings–>Select Network Services–>click on Details–>Select DNS–>ok
• While installing through Active Directory (DCPROMO): (During installation it asks for CD)
• Independently: Programs –>Settings –>Control Panel –Add/Remove Programs –>Add/Remove Windows Components –>Select the Network Services–>Click on properties –>Select DNS –>OK (During the installation it asks for CD)

4. How To Open Dns?

Start–>Programs–>Administrative Tools–>DNS

Or

Start–>Run–>dnsmgmt.msc

Or

Start–>Run –>cmd –>dnsmgmt.msc

5. How To Configure The Dns?

Open the DNS Console. Then you will find there

• DNS
• Server name
• Forward Lookup Zone
• Reverse Lookup Zone

Note:
If you have selected create automatically zones during the setup, then it creates the root zone and domain zone under forward lookup zone. If no zones are there under forward lookup zone first create root zone then create domain zone.

6. What Tabs Are There On Properties Of Domain?

Domain properties contain the following tabs:

• General
• Start of Authority (SOA)
• Named servers
• WINS
• Zone transfers

7. What Tabs Are There On Properties Of Sever?

Server properties contain the following tabs:

• Interface
• Forwarders
• Advanced
• Root hints
• Logging
• Monitoring

8. Where To Create The Primary, Secondary, Active Directory Integrated Zones?

• If you want to create an Active Directory integrated zone, the server must be Domain Controller.
• If you want to create the Primary DNS, you can create on Domain Controller or Member server. But if create on member you could not get 4 options under the domain which are meant for Active directory.
• You can create Secondary zone on a Member Server or on a Domain Controller. There is no difference between them.

9. What Commands Do We Use For Dns?

We use the following commands for DNS:

• Nslookup (and all interactive mode commands)
• Ipconfig /fulshdns
• Ipconfig /registerdns

10. What Is The Purpose Of Forward Lookup?

Forward lookup resolves the Hostnames (Friendly Name) to IP addresses.

11. What Is The Purpose Of Reverse Lookup Zone?

Reverse lookup resolves the IP addresses to Host names.

12. What Is The Difference Between Primary Zone And Secondary Zone?

• Primary zone has read and write permissions, whereas Secondary zone has read only permission.
• Secondary zone is used for Backup and Load balancing.

13. How To Check Whether Dns Is Working Or Not?

In order to check whether a DNS is working or not, type the command “nslookup” in command prompt. It will give the DNS server name and its IP address.

14. What Is Dynamic Updates In Dns?

Generally we need to create a host record for newly joined computer (either client or Member server or Domain controller). If you enable dynamic Update option, then DNS itself creates associated host record for newly joined computers.

15. How To Get Dynamic Update Option?

Right Click on any zone –>properties –>on General tab u will get

Allow Dynamic Updates? [_Yes/No/Secure Updates]

Note:
Put always Dynamic Updates “YES”

Note:
If it is Active Directory Integrated zone you will get above three options.

But if it is Primary or Secondary zone you will get only “YES/NO” (You won’t get secure updates)

16. What Is Name Resolution?

The process of translating the name into some object or information that the name represents is called name resolution. A telephone book forms a namespace in which the names of telephone subscribers can be resolved to the phone numbers.

17. What Is A Zone?

Also called a zone of authority, zone is a subset of the Domain Name System (DNS) namespace that is managed by a name server. A database of records is called a zone.

18. What Is An Iterative Query?

The query that has been sent to the DNS server from a Client is called iterative query.
(i. e., iterative query is nothing but gives the answer for my question, don’t ask to contact that person or this person or don’t say something else. Simply just answer to my question. That’s all)

19. What Is Recursive Query?

Your DNS server requests the root level DNS server for specific IP address. Now DNS server says I don’t know but I can give the address other person who can help you in finding IP address.

20. What Type Of Records Do We Find In Dns Database?

The most general records found in DNS database are

• Host Record (A record)
• Mail Exchange Record (MX record)
• Canonical name or CNAME record (CNAME)

21. What Is Ptr Record?

PTR record is created in Reverse lookup zone. It is the record to main database for reverse lookup zone purposes (to convert from IP address to host names). Each host record in forward lookup should have an associated pointer record in reverse lookup zone.

Generally first you will create a Forward lookup zone. Then go for Reverse lookup zone. Now we have to create associated pointer records for host records in forward lookup zone. If you are creating a host record in forward lookup zone after creating reverse lookup zone then here we need not to create a pointer record by coming to reverse lookup zone. When creating new host, click on the check box of create associated pointer record. Then it automatically creates associated pointer record in reverse lookup zone.

22. Is There Any Possibility To Have Two Primary Dns Zones?

No, we cannot have two primary DNS zones. Why because if u have two primary DNS zones some clients contacts first one, some clients contacts second one according to their configuration in TCP/IP properties. Then you will get problems. Actually Primary DNS zone means Single master. i.e., master is only one that is only one primary DNS zone. But you can have as many as Secondary zones.

To overcome from above problem (i.e., single master problem) in Windows 2000 we have Active Directory Integrated zones, which are multi masters.

23. What Is The Default Time Setting In Primary Zone To Refresh, Retry, Expire Intervals For Secondary Zone?

The default settings are

• To Refresh interval 10 minutes
• To Retry interval, 15 minutes
• To Expire after 1 day

24. Suppose The Secondary Zone Is Expired; Now How To Solve The Problem?

First go to primary zone check primary zone is working or not.

IF primary zone is working then go to secondary zone, Right click on zone name select the “Transfer from Master” then it automatically contacts the primary DNS, if any updates are there then it takes the updates from the Primary.

25. How To Know Whether The Recent Changes In Primary Zone Are Updated To Secondary Zone Or Not?

• Compare the Serial Number on Start of Authority tab in both secondary on primary DNS zone properties.
• If both are same then recent updates are made to secondary zone.
• If not (i.e., secondary is less then primary) click on “Transfer from Master”

26. How To Pause The Zone?

• Click on the Pause button.
• Click on General tab
• Go to properties of a zone

Note: When you install a Windows 2000 DNS server, you immediately get all of the records of root DNS servers. So every windows 2000 DNS server installed on Internet has pre configured with the address of root DNS servers. So every single DNS server in the Internet can get root servers.

27. What Is A Forwarder?

(Open DNS console ==> Right click on Domain name ==> Click on forwarder tab)

A forwarder is server, which has more access than the present DNS server. May be our present DNS server is located in internal network and it cannot resolve the Internet names. Maybe it is behind a firewall or maybe it is using a proxy server or NAT server to get to the Internet. Then this server forwards the query to another DNS server that can resolve the Internet names.

Command prompt commands:

• Type Nslookup to get into the Nslookup mode.
• Type set type=SOA then press enter type domain name
• Type set type=NS then press enter; and type domain name.
• Type set type=ALL then press enter.

Note: To come out from Nslookup mode type exit.

28. When Developing Naming Strategy, Which Dns Server Should We Use?

Microsoft suggests that we use Windows 2000 DNS server. If you want to get 100% functionality you have to use 2000 DNS server. But you can also use BIND (Berkeley internet name domain) DNS servers, but if you want you use with Windows 2000 you should have at least Bind version 4.9.7. (Previous versions don’t support SRV records)

29. What Is Caching Only Dns Server?

• Just install the DNS service into your windows 2000 server. Then it is called caching only DNS server, because it starts working for your clients to resolve the Internet names to IP address.
• When you are installing DNS service at that time it is preconfigured with root DNS servers IP addresses.
• If anybody wants to resolve the records that belong to your domain then you need to configure your DNS server appropriately.

30. Suppose Under The Forward Lookup Zone _msdcs, _tcp, _upd, _sites Are Not There (or You Have Deleted Unexpectedly). How To Get Them Back?

To get them back, simply just stop and start the netlogon service.

Type the following commands to stop and start the net logon service:

• Net stop netlogon
• Net start netlogon

Whenever you create a root zone (i.e., “.”) in a DNS server, the forwards, and root hints tabs will be disabled on that DNS server.

• RAID 0 and RAID 1 has got excellent Read and Write performance

44. What Is The Difference Between Raid 1 And Raid 5 ?

•  RAID 1 – Mirroring – This RAID configuration gives you maximum redundancy as the same data is written into two disks at a time. But this solution will be costly as you always need to have disks double of what you actually require. Minimum 2 disks required.
• RAID 5 – This RAID is the most popular RAID configuration. This works on the parity principle. Minimum 3 disks required. Even if one disk fail, the data of the failed disk can be calculated from the parity stored in the other 2 disks.

45. How To Replace A Failed Raid Controller ?

This depends on the type of controller used. If you are using modern RAID controllers and are trying to replace with the same model, then the RAID should work without any issues as the RAID configuration or metadata is stored in the disk array.

54. What Is Urgent Replication In Ad ?

Normally, a change in a DC (say DC1) is notified to its replication partner(say DC2) after 15 seconds. Once the change is notified, DC2 makes the change in its database. DC2 then notifies its replication partner after another 15 seconds. If it’s a multi-site setup, the 15 seconds delay would cost a big delay for the final recipient DC. Suppose if the change was an ‘Account Lock Out’, this big delay will be a pain. Here comes Urgent notification. Urgent notification bypasses the change notification delay and processes the change immediately across all DCs.

55. How To Migrate Ad Location To Another ? (from C:ad To D:ad)

• First, stop the Active Directory Domain Services
• Open Command Prompt with Admin privilege
• Run ntdsutil tool
• In the ntdsutil prompt, type Activate instance ntds

58. I Want To Look At The Rid Allocation Table For A Dc. What Do I Do?

Dcdiag.exe /TEST:RidManager /v | find /i “Available RID Pool for the Domain”

59. Why Can’t You Restore A Dc That Was Backed Up 4 Months Ago?

The reason is ‘Tombstoning’ . If a domain controller was restored from a backup that was older than the tombstone lifetime, then the domain controller might contain deleted objects, and because the tombstones are deleted from the replica, the deletion event does not replicate into the restored domain controller. This is why Backup does not allow you to restore data from a backup that is older than the tombstone lifetime.

60. Can I Deploy Non-msi Software With Gpo?

Yes, you can. Apart from MSI packages, GPO also supports deployment of ZAP files

61. How Frequently Is The Client Policy Refreshed ?

By default, group policy is updated in the background every 90 minutes.You can specify an update rate from 0 to 44,640 minutes (31 days). If you select 0 minutes, the computer tries to update Group Policy every 7 seconds. However, because updates might interfere with users’ work and increase network traffic, very short update intervals are not appropriate for most installations.

The refresh interval can be configured manually using group policy – GPO –> Computer Configuration –> Administrative Templates –> System –> Group Policy –> Set Group Policy refresh interval for Computers

62. How Does The Group Policy ‘no Override’ And ‘block Inheritance’ Work ?

No Override – This prevents child containers from overriding policies set at higher levels

Block Inheritance – Stops containers inheriting policies from parent containers

63. Which Esxtop Metric Will You Use To Confirm Latency Issue Of Storage ?

65. Recommended Iscsi Configuration Of A 6 Nic Infrastructure ? (answer Changes As Per The Infrastructure Requirements)

• 2 NICs for VM traffic
• 2 NICs for iSCSI traffic
• 1 NIC for vMotion
• 1 NIC for management network
• Post conversion steps in P2V
• Adjust the virtual hardware settings as required
• Remove non present device drivers
• Remove all unnecessary devices such as serial ports, USB controllers, floppy drives etc..
• Install VMware tools

66. Iscsi Port Binding Considerations ?

• Array Target iSCSI ports must reside in the same broadcast domain and IP subnet as the VMkernel port.
• All VMkernel ports used for iSCSI connectivity must reside in the same broadcast domain and IP subnet.
• All VMkernel ports used for iSCSI connectivity must reside in the same vSwitch.
• Currently, port binding does not support network routing.

67. What Is Iscsi Port Binding ?

Port binding is used in iSCSI when multiple VMkernel ports for iSCSI reside in the same broadcast domain and IP subnet, to allow multiple paths to an iSCSI array that broadcasts a single IP address.

68. Recommended Iscsi Configuration?

A separate vSwitch, and a separate network other than VMtraffic network for iSCSI traffic. Dedicated physical NICs should be connected to vSwitch configured for iSCSI traffic.

69. What Is Vsan?

It is a hypervisor-converged storage solution built by aggregating the local storage attached to the ESXi hosts managed by a vCenter. 

70. Explain About Backup Types?

Backup types:

• Full backup – Will take the backup of all selected files and reset the archive bit
• Copy backup – Will take the backup of all selected files but does not reset the archive bit
• Incremental backup – Will take the backup of files whose archive bits are set and resets it after backup
• Differential backup – Will take the backup of files whose archive bits are set but does not reset it after backup 

71. Explain About Raid?

• Redundant Array of Independent disks
• A category of disk drives that uses 2 or more drives in a combination for redundancy and performance
• Most common RAIDs: RAID 0(Striped), RAID 1(Mirroring), RAID 5

72. Explain About Global Catalog?

Global Catalog

• Global catalog (GC) is a role handled by domain controllers in an Active directory model. 
• The global catalog stores a full copy of all objects in the directory for its host domain and a partial copy of all objects for all other domains in the forest. 
• ‘Partial copy’ refers to the set of attributes that are most used for searching every object in every domain.
• All domain controllers can be promoted as a GC.
