QUESTIONS AND ANSWERS (CCNA Part-5)

1. What algorithm does OSPF use to compute its route table?
A: OSPF uses the shortest path first (SPF) algorithm, which is also known as the Dijkstra algorithm.
2. What three tables does an OSPF router build?
A: OSPF routers build an adjacencies database, a link-state or topological database, and a route table.
3. What is the significance of the DR and BDR?
A: A DR, or Designated Router, serves as a point of contact for an OSPF router on a multiaccess  network, because the DR is responsible for collecting routing updates from routers on the link and distributing these updates to all other routers on the link. If the DR goes offline, the BDR, or Backup Designated Router, takes over the DR’s functions.
4. How are the DR and BDR selected?
A: The DR and BDR are selected based on router priority. If there is a tie, the router with the highest router ID is preferred.
5. How is the router ID determined?
A: The router ID is the highest IP address configured on any of the router’s loopback interfaces. If no loopback interface is configured on the router, the router ID is the highest IP address configured on any of the router’s physical interfaces.
6. What is an ABR?
A: An ABR, Area Border Router, is a router with interfaces that connect to more than one area.
7. What is an ASBR?
A: An ASBR, Autonomous System Boundary Router, is a router with interfaces that connect to more than one autonomous system.
8. What is a stub area?
A: A stub area is an area that does not accept routing updates from outside its autonomous system.
9. What is a totally stubby area?
A: A totally stubby area is an area that does not accept routing updates from outside its area.
10. What is a virtual link?
A: A virtual link logically connects an ABR that does not physically connect the backbone Area 0 to another ABR that does connect to the backbone area, thereby linking an entire area to the backbone area.
Enjoy With this Questions and Answers.

Active Directory Terms -(Various Objects and their Functions)

Active Directory Terms -(Various Objects and their Functions )
What is an OU in AD ?
What is user accounts in AD ?
What is Group Accounts In AD ?
What is Computer Account in AD ?

What is  an OU in AD?
Answer:
  •  An Organizational Unit is a container (read: folder) that holds AD Objects like User Accounts, Computer Accounts, and Groups.
  •  OU’s help to keep your Objects organized, but also are used to control what Users can and can’t do.
  • You can also pass the buck by delegating control over OU’s.
What is User Account ?
Answer:

    User Account : User Account is  an Active Directory Object that allows users to access the resources.

What is Group Accounts In AD ?
Answer:

Group Account : An Active Directory Object that allows or denies access to network resources ( Like Folder and Printers ) for users and computers .

What is Computer Account in AD ?
Answer:

  • Computer Accounts allow AD to keep track of and control the computers in your network. A computer without an Account in AD can’t access the network—it’s a security thing
  • Computer Accounts live in OU’s, which will allow you to install software to all machines in an OU at once!
  • When you join a computer to a Domain (you’ll need Domain Administrator level credentials), a Computer Account is automatically created in AD.
  • After Joining the Domain, you’ll have to move your Computer Accounts to the appropriate OU.
  • You can create accounts manually, but it’s not a very good idea. Keeping track of your computers is a really really good idea
Hope theses question and answers will help to prepare a candidate for Interview.

What is "Setup Mode" on Router ?

What is "Setup Mode" on Router ?
If the router is brand new, it has no startup-config file. Therefore, when it boots, it immediately enters Setup mode.
Setup mode is a special, guided routine that asks you a series of questions and uses your responses to make basic configuration entries.
There are two ways to enter setup mode:
  •  Boot the router without the startup-config file. This happens when you erase the current startup-config file, or when you boot a new router.
  •  Use the setup command from privileged mode.
You can exit setup mode without answering all the questions by pressing Ctrl + C.
The information you've entered to that point will not be saved.

Cisco routers and switches come with the following defaults:
  •  No set passwords. During setup mode, passwords are created.
  •  All router interfaces are in shutdown mode until they are enabled.
  •  All switch interfaces are enabled and ready to forward packets.

Active Directory ( Some Questions and Answer ) ?

        Active Directory
1.    What is Active Directory?
2.    What is a Domain Controller?
3.    What is a Domain?
4.    What is a Server Role?
5.    What is DNS?

 What is Active Directory ? 
 Answer :
  •  Active Directory is the Brain of a Windows Server Network.
  •  It’s a database that keeps track of a huge amount of stuff and gives us a  centralized way to manage all our network machines, users, and resources.Such as 
    •     Users and Groups
    •     Services (i.e. Email, etc.)
    •     Resources (Printers, Shared Folders, etc. )
What is Domain Controller ?  Answer :
  •      A Domain Controller is a Windows Server Machine that runs Active Directory Domain Services.
  •    Think of it as the Boss of your network.
  •   You may have multiple Domain Controllers that all have copies of the same Active  Directory  database.
What is a Domain?
Answer:
  •  A Windows Server domain is a logical group of computers running versions of the Microsoft Windows operating system that share a central directory database.
  •  The machines are all named with part of a Domain name like india.local (also called a “suffix”) and are registered in the Active Directory Database so they can be managed.               Big word: “Namespace”
  • Users are also part of the “namespace.”
  • Example: Your email address is part of a domain namespace:– moin@india.local
  • Note: Email-like logins are also called “User Principle Names” when used to log into a Server 2008 network.

What is a Server Role?
Answer:
  • A Server Role is a major job that a Server can perform.
  • It’s recommended that a Server not have too many Roles Everybody needs a job—even servers!
  • A Domain Controller usually has only two Roles:
                             •Active Directory Domain Services
                              •DNS
What is DNS?
Answer:
  • DNS is a service provided by a Server that allows you to find other computers in your network.
  • DNS allows you to type in a friendly name of a machine instead of its IP Address, allowing your client  to get the IP address from the DNS server and go find  the resource.
  • Without DNS, Active Directory will not work.
  • It is recommended that you integrate  DNS with Active Directory to make your IT life easier.  
Hope These will help to understand Active directory who are new to Active Directory.
Enjoy Active Directory.
