File Name: active directory interview questions and answers 2012 r2 server.zip
Active directory just as the name suggests is a directory service. This directory service acts as a shared platform of information for organizing, managing, locating and administering the daily items and the network sources.
Define what is Active Directory? Answer: Active Directory is a Meta Data. Active Directory is a data base which store a data base like your user information, computer information and also other network object info.
Answer: Domain local groups assign access permissions to global domain groups for local domain resources. Global groups provide access to resources in other trusted domains. Universal groups grant access to resources in all trusted domains. I am trying to create a new universal user group. Answer: Universal groups are allowed only in native-mode Windows Server environments. Native mode requires that all domain controllers be promoted to Windows Server Active Directory. What is an IP address? Answer: Every device connected to the public Internet is assigned a unique number known as an Internet Protocol IP address.
IP addresses consist of four numbers separated by periods also called a 'dotted-quad' and look something like In computer networking, an Internet Protocol IP address consists of a numerical identification logical address that network management assigns to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes.
The role of the IP address has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there. What is subnet Mask?
Answer: A subnet short for "subnetwork" is an identifiably separate part of an organization's network. Typically, a subnet may represent all the machines at one geographic location, in one building, or on the same local area network LAN. Having an organization's network divided into subnets allows it to be connected to the Internet with a single shared network address.
Without subnets, an organization could get multiple connections to the Internet, one for each of its physically separate subnetworks, but this would require an unnecessary use of the limited number of network numbers the Internet has to assign.
It would also require that Internet routing tables on gateways outside the organization would need to know about and have to manage routing that could and should be handled within an organization.
What is ARP? In an Ethernet local area network, however, addresses for attached devices are 48 bits long. ARP provides the protocol rules for making this correlation and providing address conversion in both directions. How ARP Works? Answer: When an incoming packet destined for a host machine on a particular local area network arrives at a gateway , the gateway asks the ARP program to find a physical host or MAC address that matches the IP address.
The ARP program looks in the ARP cache and, if it finds the address, provides it so that the packet can be converted to the right packet length and format and sent to the machine. If no entry is found for the IP address, ARP broadcasts a request packet in a special format to all the machines on the LAN to see if one machine knows that it has that IP address associated with it.
A machine that recognizes the IP address as its own returns a reply so indicating. Define what is Active Directory Domain Services? Define what is domain? Answer: A domain is a set of network resources applications, printers, and so forth for a group of users. The user need only to log in to the domain to gain access to the resources, which may be located on a number of different servers in the network.
A domain address might look something like Define what is domain controller? Answer: A Domain controller DC is a server that responds to security authentication requests logging in, checking permissions, etc.
A domain is a concept introduced in Windows NT whereby a user may be granted access to a number of computer resources with the use of a single username and password combination. What is a default gateway? What happens if I don't have one?
Answer: a gateway is a routing device that knows how to pass traffic between different subnets and networks. A computer will know some routes a route is the address of each node a packet must go through on the Internet to reach a specific destination , but not the routes to every address on the Internet. It won't even know all the routes on the nearest subnets. A gateway will not have this information either, but will at least know the addresses of other gateways it can hand the traffic off to.
Your default gateway is on the same subnet as your computer, and is the gateway your computer relies on when it doesn't know how to route traffic. The default gateway is typically very similar to your IP address, in that many of the numbers may be the same.
However, the default gateway is not your IP address. To see what default gateway you are using, follow the steps below for your operating system. What is a subnet? Answer: In computer networks based on the Internet Protocol Suite, a subnetwork, or subnet, is a portion of the network's computers and network devices that have a common, designated IP address routing prefix cf.
A routing prefix is the sequence of leading bits of an IP address that precede the portion of the address used as host identifier or rest field in early Internet terminology. What is an RFC? Name a few if possible not necessarily the numbers, just the ideas behind them What is RFC ?
Efforts are in progress within the community to find long term solutions to both of these problems. Meanwhile it is necessary to revisit address allocation procedures, and their impact on the Internet routing system. What is CIDR? For example: CIDR addresses reduce the size of routing tables and make more IP addresses available within organizations.
CIDR is also called supernetting. You have the following Network ID: What is the IP range for your network? Answer: You need at least hosts per network. How many networks can you create?
What subnet mask will you use? You need to view at network traffic. What will you use? Name a few tools? Answer: Monitoring network traffic tool Q. How do I know the path that a packet takes to the destination? Answer: use "tracert" command-line Q. What does the ping Answer: The ping command will send roundtrip packets to a destination other PC, router, printer, etc. The The -l is how big the packet should be in bytes. The default is 32, if the -l parameter is not used.
And the -n is saying to send, it times. The default is 4, when this parameter is not used. What is DHCP? What are the benefits and drawbacks of using it? In a networked environment it is a method to assign an 'address' to a computer when it boots up. Benefit: A system administrator need not worry about computers being able to access networked resources Q.
Also, DHCP helps prevent address conflicts caused by a previously assigned IP address being reused to configure a new computer on the network. Reduces configuration management Using DHCP servers can greatly decrease time spent configuring and reconfiguring computers on your network. Servers can be configured to supply a full range of additional configuration values when assigning address leases. These values are assigned using DHCP options.
Also, the DHCP lease renewal process helps assure that where client configurations need to be updated often such as users with mobile or portable computers who change locations frequently , these changes can be made efficiently and automatically by clients communicating directly with DHCP servers.
Answer: HCP uses a client-server model. The server database includes the following: Valid configuration parameters for all clients on the network. Valid IP addresses maintained in a pool for assignment to clients, plus reserved addresses for manual assignment. Duration of a lease offered by the server. The lease defines the length of time for which the assigned IP address can be used. With a DHCP server installed and configured on your network, DHCP-enabled clients can obtain their IP address and related configuration parameters dynamically each time they start and join your network.
DHCP servers provide this configuration in the form of an address-lease offer to requesting clients. Name 2 scenarios.? Answer: Open Windows Components Wizard. Under Components , scroll to and click Networking Services. Click Details. Click Next.
Define what is Active Directory? Answer: Active Directory is a Meta Data. Active Directory is a data base which store a data base like your user information, computer information and also other network object info. Answer: Domain local groups assign access permissions to global domain groups for local domain resources. Global groups provide access to resources in other trusted domains. Universal groups grant access to resources in all trusted domains. I am trying to create a new universal user group.

The 'domain' is simply your computer address not to confused with an URL. A domain address might look something like
Below are the Active Directory Interview Questions and answers. However there are more Interview question:. The global catalog is stored on domain controllers that have been designated as global catalog servers and is distributed through multimaster replication. Searches that are directed to the global catalog are faster because they do not involve referrals to different domain controllers.
