MCTS 70-642 Microsoft 70 642: Network Infrastructure, Configuring 4

Question 1

A Windows Server 2008 R2 DHCP server is failing to lease addresses. You run 'ipconfig /all' on the server and notice it has an APIPA address. What is the most likely problem?

Accepted Answer

The DHCP server itself is not authorized in Active Directory

Answer

In an Active Directory environment, a DHCP server must be authorized in AD before it can lease addresses; an unauthorized server will not service client requests.

Question 2

You need to allow remote users to access internal resources without requiring a VPN client installation, using only a web browser. Which solution should you implement?

Accepted Answer

SSL VPN via Remote Desktop Gateway

Answer

Remote Desktop Gateway (RD Gateway) allows remote users to connect to internal RDP resources over HTTPS using only a web browser or RDP client without a separate VPN client.

Question 3

An administrator configures a DNS server with a GlobalNames zone. What is the purpose of this zone?

Accepted Answer

To replace WINS for single-label name resolution across the enterprise

Answer

The GlobalNames zone in Windows Server 2008 allows administrators to support single-label name resolution (like WINS) in environments where WINS is being phased out.

Question 4

You need to capture all network traffic passing through a specific network interface on a Windows Server 2008 R2 server for analysis. Which built-in tool should you use?

Accepted Answer

Network Monitor (netmon)

Answer

Network Monitor (netmon) is a built-in packet capture tool that captures and analyzes network traffic on Windows Server 2008 R2 interfaces.

Question 5

A DNS zone is configured as Active Directory-integrated. What is a key advantage over a standard primary zone?

Accepted Answer

It enables multi-master replication and eliminates a single point of failure

Answer

AD-integrated zones use multi-master replication through AD replication, so any domain controller running DNS can accept updates, eliminating a single point of failure.
