MCSE Microsoft MCSE: 70-291 3 — Questions and Answers
Question 1: You are configuring DHCP superscopes on Windows Server 2003. When is a superscope required?
- When multiple logical IP subnets exist on a single physical network segment (multinet) (Correct answer)
- When you want to reserve IP addresses for specific MAC addresses
- When DHCP clients span multiple physical subnets connected by a router
- When you need to configure option 003 gateway on a per-class basis
Correct answer: When multiple logical IP subnets exist on a single physical network segment (multinet)
A superscope groups multiple child scopes to serve clients on a multinet — a single physical segment hosting more than one logical subnet.
Question 2: Which type of DNS record is used to map an IPv4 address back to a fully qualified domain name in a reverse lookup zone?
- PTR (Correct answer)
- A
- CNAME
- SOA
Correct answer: PTR
PTR (pointer) records in reverse lookup zones map IP addresses to hostnames, enabling reverse DNS resolution.
Question 3: A branch office router needs to reach headquarters only when traffic is present, reducing WAN costs. Which RRAS feature should you configure?
- Demand-dial routing with idle disconnect timeout (Correct answer)
- Persistent static routes with metric 1
- BGP dynamic routing over a permanent leased line
- IPSec tunnel mode with continuous keepalives
Correct answer: Demand-dial routing with idle disconnect timeout
Demand-dial interfaces bring up the WAN connection only when routable traffic is detected and disconnect after the idle timeout, minimizing connection costs.
Question 4: You run 'netsh routing ip show rtmroutes' and notice a route with a metric of 256. What does a metric of 256 typically indicate in Windows Server 2003 RRAS?
- The route is unreachable or the interface is down (Correct answer)
- It is an automatically summarized classful route
- The route was learned via RIP version 1
- The route is a host route injected by IPSec
Correct answer: The route is unreachable or the interface is down
In Windows RRAS, a metric of 256 (infinite for RIP) flags a route as unreachable, usually because its interface has gone down.
Question 5: You need to ensure that only computers with healthy antivirus definitions can connect to the network via VPN. Which Windows Server 2003 feature enforces this policy?
- Network Access Quarantine Control (RRAS quarantine) (Correct answer)
- Routing and Remote Access packet filters
- IPSec transport mode with AH protocol
- Remote access policy time-of-day restrictions
Correct answer: Network Access Quarantine Control (RRAS quarantine)
Network Access Quarantine Control places VPN clients in a restricted quarantine network until a notifier script verifies compliance with health policies.
Question 6: A Windows Server 2003 WINS server database has grown very large and resolution is slowing. Which WINS maintenance action reclaims space by permanently removing records marked as extinct?
- Compact the WINS database using jetpack.exe (Correct answer)
- Run WINS consistency check from the console
- Force replication with all push/pull partners
- Restart the WINS service to flush the in-memory cache
Correct answer: Compact the WINS database using jetpack.exe
jetpack.exe compacts the WINS (and DHCP) Jet database offline, permanently reclaiming space from deleted and extinct records.
Question 7: You configure a Windows Server 2003 DNS server to forward unresolved queries to your ISP's DNS servers. However, you want the server to attempt root hints resolution if all forwarders fail. Which setting achieves this?
- Enable 'Do not use recursion for this domain' is unchecked (allow fallback to root hints) (Correct answer)
- Add the ISP DNS IPs as additional root hints entries
- Configure conditional forwarding for the '.' (root) zone
- Set the forwarder timeout to 0 seconds
Correct answer: Enable 'Do not use recursion for this domain' is unchecked (allow fallback to root hints)
When 'Do not use recursion for this domain' is unchecked on the Forwarders tab, Windows DNS falls back to root hints if all configured forwarders are unreachable.
