The ABC.com network consists of a single Active Directory domain named ABC.com. All servers on the ABC.com network run Windows Server.

ABC.com contains a Development department. ABC.com contains a domain controller named ABC-SR24 which is also configured as a DNS Server. A ABC.com employee named Clive Wilson works in the Development department. One

morning Clive Wilson complains that he cannot connect to another network server.

During investigation, you notice that nslookup queries sometimes take a long time and sometimes fail altogether.

You suspect that there is a problem with ABC-SR24.

How would you configure monitoring on ABC-SR24 so that you can review individual name resolution queries?

A. Use System Monitor to monitor host resolution queries on ABC-SR24.

B. Use Event Viewer to view the DNS event log on ABC-SR24.

C. Select the Log packets for debugging option on the Debug Logging tab in the DNS server properties on ABC-SR24.

D. Use Network Monitor to capture DNS query packets on ABC-SR24.

You are working as the administrator at ABC.com. The ABC.com network consists of a single Active Directory domain named ABC.com. The ABC.com network contains a DMZ that contains a two-node Network Load Balancing cluster, which

is located in a data centre that is physically impenetrable to unauthorized persons.

The cluster servers run Windows Server Web Edition and host an e-commerce website. The NLB cluster uses a virtual IP address that can be accessed from the Internet.

What can you do to mitigate the cluster's most obvious security vulnerability?

A. Configure the cluster to require IPSec.

B. Configure the network cards to use packet filtering on all inbound traffic to the cluster.

C. Use EFS on the server hard disks.

D. Configure intrusion detection the servers on the DMZ.

E. Configure Mac addressing on the servers in the DMZ.

You are working for an administrator for ABC.com. The ABC.com network consists of a single Active Directory domain named ABC.com. All the servers on the network run Windows Server servers.

You have configured four servers in a network load balancing cluster. You need to enable the cluster in unicast mode although each server only has one network card. After your configuration, the NLB cluster has successfully converged.

You discover that you can optimize the use of the cluster by moving a specific application to each node of the cluster. However for this application to execute, all the nodes of the cluster must be configured by a Network Load Balancing Port

Rule.

When you open Network Load Balancing Manager on one of the NLB nodes, you receive a message saying that Network Load Balancing Manager is unable to see the other nodes in the cluster.

How can you add a port rule to the cluster nodes?

A. By opening Network Load Balancing Manager on a different host.

B. By creating an additional virtual IP address on the cluster.

C. By modifying the Network Connection Properties on every host.

D. By removing each host from the cluster before creating the port rule.

You have recently hired a new junior administrator to assist you in running the network for a medium-sized manufacturing company. You are explaining to your new assistant that AD objects are assigned security descriptors to allow you to implement access control. You tell your assistant that the security descriptor contains several different components. Which of the following are contained in the security descriptor for an object? (Select all that apply.)

A. Discretionary access control list

B. System access control list

C. Dynamic access control list

D. Ownership information

You are setting up a procedure to keep documents exchanged between members of the R and D department secret. They will be sending these documents across the Internet to each other. Which PKI process will you need to employ to achieve this?

A. Confidentiality

B. Non-repudiation

C. Authentication

D. Data Integrity
