You should not first click Home in the banner at the top. You would take this step to open the updates services administration home page. Before you could change the settings, you must still stop synchronizing. The Home page includes a command to do this.

You should not first click Updates in the banner at the top. You would do this to view the available updates and update options. You cannot modify synchronization settings from this page.

You should not first click Options in the banner at the top. You would do this to display the Options menu. The menu lets you access synchronization, automatic update authorization and computer options. You cannot directly modify the synchronization options from this page.

Objective: Implementing, Managing and Maintaining Name Resolution.
SubObjective: Install and configure the DNS server service. Configure DNS forwarding.

Single answer, multiple choice.

You manage the servers for one of your company's branch offices. This office does not have a connection to the Internet, but it does have a dedicated connection to your company's main office. You install the domain name system (DNS) server service on a computer named DNS-Branch5 that is running Windows Server 2003. You create a DNS zone named branch5.bcdtrain.com on DNS-Branch5, and you configure the client computers and other servers at your office to use DNS-Branch5 as their DNS server. The DNS administrator at your company's main office delegates the subdomain branch5.bcdtrain.com to DNS-Branch5.

You want all DNS queries for Internet-based resources to be processed by DNS-Main, which is a computer running DNS and Windows Server 2003 at the main office. You also want to minimize the amount of DNS traffic on your network.

What should you do to accomplish these goals?

A. Configure DNS-Branch5 as a forwarder.
B. Add the Internet protocol (IP) address of DNS-Main to the Root Hints of DNS-Branch5.
C. Configure DNS-Branch5 to use DNS-Main as a forwarder.
D. Define the Internet protocol (IP) address of DNS-Main as an alternate DNS server for your client computers and servers.

Answer:
C

Tutorial:
You should configure DNS-Branch5 to use DNS-Main as a forwarder to accomplish your goals. When you do so, you should also select the option "Do not use recursion for this domain" for the entry "All Other DNS Domains" on the Forwarders tab of the Properties dialog box of DNS-Branch5 in the DNS console. With this option enabled, DNS-Branch5 will forward all requests to DNS-Main that cannot be answered from data in the zone that it hosts or from its DNS cache.

You should not configure DNS-Branch5 as a forwarder. A forwarder is a DNS server to which DNS queries are forwarded, not a DNS server that does the forwarding. You do not have to configure a DNS server to be a forwarder.

You should not add the IP address of DNS-Main to the Root Hints of DNS-Branch5. You should use Root Hints to identify root name servers that a DNS server should use. If a DNS server can access the Internet, the Root Hints should include the addresses of the Internet's root name servers, which can be loaded from the file named cache.dns that is copied to a server when you install the DNS server service on the server. If a DNS server cannot access the Internet, you should add the IP address of the DNS server or servers that host the root zone for your internal network.

You should not define the IP address of DNS-Main as an alternate DNS server for your client computers and servers. Because one of your goals is to minimize the amount of DNS traffic on your network, you should not configure computers to use multiple DNS servers. By configuring the computers to use only DNS-Branch5, you reduce overall DNS traffic because DNS-Branch5 can cache information it receives from DNS-Main and then use this cached information to respond to DNS queries from other computers on the branch network.

Objective: Implementing, Managing and Maintaining IP Addressing.
SubObjective: Troubleshoot TCP/IP addressing. Diagnose and resolve issues related to automatic private IP addressing (APIPA).

Single answer, multiple choice.

You are an administrator for a large organization. Servers on the network run Windows Server 2003. Client computers run Windows XP Professional.

You have added a router to your network to create a new subnet. The client computers on the new subnet are having trouble connecting to the servers. One of the client computers has an IP address of 169.254.10.22. The dynamic host configuration protocol (DHCP) server on the network is working properly.

You need to correct the problem using as little administrative effort as possible.

What should you do?

A. Disable automatic private IP addressing (APIPA) on the client computers.
B. Install a DHCP relay agent on the network.
C. Configure the client computers with static IP addresses.
D. Install a DHCP server on the subnet.

Answer:
B

Tutorial:
The IP address of 169.254.10.22 on the client computer indicates that it has been configured by APIPA. Installing a DHCP relay agent will allow a DHCP server to assign IP addresses to subnets of which it is not a part. The DHCP relay agent is installed on a router or on a client computer on an alternate subnet. It forwards requests to the DHCP server on the other subnet. This would allow the proper IP addresses to be assigned to the client computers so they can communicate on their subnets.

The client computers could not connect to a DHCP server on the network, so they assigned themselves IP addresses from the pool of addresses used for APIPA. These addresses are in the range of 169.254.0.1 to 169.254.255.254, which is the range of addresses reserved for Microsoft for APIPA. Disabling APIPA would cause the client computers to receive all zeroes for the IP addresses.

Configuring the client computers with static IP addresses would work. However, with a large number of client computers in an enterprise, this would be a cumbersome task to maintain.

Installing a DHCP server on the subnet will provide IP addresses to the client computers, but it does not meet the goal of using as little administrative effort as possible.
