MCTS 70-642 Routing, WAN & Network Connectivity 1 — Questions and Answers
Question 1: Which Windows Server 2008 role enables IP routing and VPN connectivity?
- Web Server (IIS)
- Routing and Remote Access Service (RRAS) (Correct answer)
- Network Policy Server
- File Services
Correct answer: Routing and Remote Access Service (RRAS)
RRAS (Routing and Remote Access Service) provides IP routing, NAT, and VPN gateway functionality in Windows Server 2008.
Question 2: What VPN protocol in Windows Server 2008 encapsulates PPP frames within IP datagrams and uses IPsec for encryption?
- PPTP
- L2TP/IPsec (Correct answer)
- SSTP
- IKEv2
Correct answer: L2TP/IPsec
L2TP/IPsec tunnels PPP frames using L2TP and secures them with IPsec encryption, providing strong authentication and data integrity.
Question 3: Which routing protocol is a distance-vector protocol supported by RRAS in Windows Server 2008?
- OSPF
- BGP
- RIP version 2 (Correct answer)
- IS-IS
Correct answer: RIP version 2
RIP version 2 (Routing Information Protocol) is a distance-vector routing protocol supported natively in Windows Server 2008 RRAS.
Question 4: What Windows Server 2008 feature translates private IP addresses to a public IP address for internet access?
- IPsec
- NAT (Network Address Translation) (Correct answer)
- DHCP relay
- DNS forwarder
Correct answer: NAT (Network Address Translation)
NAT translates private, internal IP addresses to a single public IP address, allowing multiple internal hosts to share internet connectivity.
Question 5: Which VPN protocol in Windows Server 2008 uses SSL/TLS over port 443 and is well-suited for traversing firewalls?
- PPTP
- L2TP/IPsec
- SSTP (Correct answer)
- GRE
Correct answer: SSTP
SSTP (Secure Socket Tunneling Protocol) uses HTTPS (port 443) to encapsulate PPP traffic, easily passing through most firewalls and web proxies.
Question 6: What command displays the current IP routing table on a Windows Server 2008 system?
- netstat -r
- ipconfig /all
- route print (Correct answer)
- tracert /route
Correct answer: route print
'route print' displays the full IP routing table including destination networks, subnet masks, gateways, interfaces, and metrics.
