MCTS 70-642 Routing, WAN & Network Connectivity 2 — Questions and Answers
Question 1: What is the purpose of a demand-dial interface in Windows Server 2008 RRAS?
- Provides always-on LAN connectivity
- Establishes a WAN connection only when traffic is destined for the remote network (Correct answer)
- Assigns DHCP addresses to VPN clients
- Monitors network bandwidth usage
Correct answer: Establishes a WAN connection only when traffic is destined for the remote network
Demand-dial interfaces connect to remote networks on-demand when traffic needs to be routed there, and disconnect when idle to save bandwidth costs.
Question 2: Which authentication protocol for dial-up and VPN in Windows Server 2008 provides mutual authentication and encrypts credentials using MS-CHAPv2?
- PAP
- CHAP
- MS-CHAPv2 (Correct answer)
- SPAP
Correct answer: MS-CHAPv2
MS-CHAPv2 (Microsoft Challenge Handshake Authentication Protocol version 2) provides mutual authentication between client and server with encrypted credential exchange.
Question 3: What Windows Server 2008 feature allows a server to act as a network bridge between a wireless and wired segment?
- Network bridging via Network Connections (Correct answer)
- RRAS demand-dial
- ICS (Internet Connection Sharing)
- DirectAccess
Correct answer: Network bridging via Network Connections
Windows Server 2008 supports network bridging through Network Connections, linking wired and wireless interfaces into a single logical network segment.
Question 4: In RRAS, what is a static route used for?
- Automatically learns routes from neighboring routers
- Manually defines a path to a specific destination network (Correct answer)
- Assigns IP addresses to remote clients
- Monitors WAN link availability
Correct answer: Manually defines a path to a specific destination network
A static route is manually configured to define a specific path to a destination network, useful for small networks or specific routing requirements.
Question 5: What is the purpose of the metric value associated with a route in the Windows routing table?
- Defines the maximum transmission unit
- Indicates the cost or preference of a route (lower is preferred) (Correct answer)
- Specifies the VLAN tag
- Sets the TTL for routed packets
Correct answer: Indicates the cost or preference of a route (lower is preferred)
A route metric represents the cost of using that route; when multiple routes exist for the same destination, the route with the lowest metric is preferred.
Question 6: Which Windows Server 2008 technology allows remote clients to connect to corporate resources without a traditional VPN by using IPv6 and IPsec?
- SSTP
- L2TP
- DirectAccess (Correct answer)
- PPTP
Correct answer: DirectAccess
DirectAccess, introduced in Windows Server 2008 R2, provides seamless remote access using IPv6 and IPsec tunnels without requiring a traditional VPN client connection.
