(TCO 1) What server role provides IEEE 802.1X authentication features? (Points : 5)        File services
       Active directory domain services
       Web server (IIS)
       Network policy and access services

Explanation / Answer

1.

The authentication features of IEEE 802.1X are as follows:

·       A successful security feature which provides security against various barriers.

·       Wired network connections are protected via set of credentials provided by an authenticated user.

·       Network policy server which provides the management of the network policies using three components RADIUS server, RADIUS proxy, and Network access protection(NAP).

·       IEEE 802.1X manage the access services provided by the server.

Thus, the option 4 network policies and access services is correct.

2.

Intersite replication does not require much planning or management because, it is automatic. Site links are used to connect different sites to each other.

Connections must be created between the sites and active directory services are used to create these connections called as site links.

The steps to manage the replication between sites in the intersite replication process are as follows:

·       Identify the sites with low cost site links.

·       Identify the well-connected sites having medium cost links.

·       Identify the remaining WAN links.

·       Create a site link for each pair of sites that cross the WAN link.

·       Make a schedule for the user needs.

This process should avoid high frequency times and site links should have a common window of time that is required for routing.

Thus, the option 2 site link is correct.

3.

A site can be considered as a physical location of some data. The benefits of the AD site are as follows:

·       Group the servers into containers to replicate the network’s topology.

·       Configure the replication mechanism between domains.

·       Mapping of TCP/IP subnets to the sites to join the correct site.

Thus, the option 1 improved replication control is correct.

4.

When there are multiple users at different access locations who wants to access an application then, there should be a mechanism that can optimize the server’s performance in relation to the application.

Application server optimization is used to provide accessibility, functionality, and availability from the applications at different locations. Different methods are used to optimize the server. Load balancing and failover management are two methods which can optimize the server.

Load balancing can increase and manage the network bandwidth. The benefits provided by the load balancing are as follows:

·       Improve the throughput

·       Decrease the latency

·       Improve the response times.

5.

The forest root domain is a type of domain naming server(DNS) which has a rule of assigning a domain name. The domain name is assigned in the prefix.suffix form. For example: technet.microsoft.com technet is prefix and microsoft.com is suffix in this example.

If user is working on single domain system then, the single domain system will act as a forest root domain. If user is working on a multiple domain system then, there should be a dedicated forest root domain.

The forest is a collection of domain names having common network resources.

6.

The organizational unit can be considered as a container to group other objects together for administrative purposes. It creates a hierarchy with in the active directory to meet the needs of the users. It can hold the users, groups, and computers.
