MCSE 70-297: Network Infrastructure Design 2 — Questions and Answers
Question 1: What is the purpose of a stub zone in Windows Server 2003 DNS?
- Contains only NS, SOA, and A records of authoritative servers (Correct answer)
- Forwards all queries to another DNS server
- Resolves names without a full zone copy
- Stores cached records from previous queries
Correct answer: Contains only NS, SOA, and A records of authoritative servers
A stub zone contains only the NS, SOA, and glue A records needed to identify the authoritative servers for a zone, reducing zone transfer traffic.
Question 2: Which routing protocol is preferred for large enterprise networks due to its scalability and support for VLSM?
- OSPF (Correct answer)
- RIP v1
- IGRP
- BGP
Correct answer: OSPF
OSPF (Open Shortest Path First) is a link-state routing protocol that supports VLSM, scales to large networks, and converges faster than distance-vector protocols.
Question 3: What is the function of the WINS server in a Windows network?
- Resolves NetBIOS names to IP addresses (Correct answer)
- Assigns IP addresses to clients
- Authenticates domain users
- Manages DNS zone transfers
Correct answer: Resolves NetBIOS names to IP addresses
WINS (Windows Internet Name Service) provides dynamic NetBIOS name-to-IP address resolution for pre-Windows 2000 applications and legacy compatibility.
Question 4: When designing a VPN solution for remote access, which protocol provides the strongest security using SSL/TLS?
- SSTP (Correct answer)
- PPTP
- L2TP
- IPSec tunnel mode
Correct answer: SSTP
SSTP (Secure Socket Tunneling Protocol) uses SSL/TLS over port 443, making it highly firewall-friendly and providing strong encryption.
Question 5: What design consideration makes a hub-and-spoke Active Directory site topology preferable over a full mesh?
- Reduced number of replication connections in large site environments (Correct answer)
- Faster replication convergence
- Support for more than 100 sites
- Automatic failover when the hub goes down
Correct answer: Reduced number of replication connections in large site environments
A hub-and-spoke topology reduces the number of site link objects and replication connections needed, simplifying management in large multi-site environments.
Question 6: Which Windows Server 2003 service provides IP address management and reduces broadcast traffic by dividing a network into subnets?
- DHCP with superscopes (Correct answer)
- WINS proxy
- DNS forwarders
- IAS server
Correct answer: DHCP with superscopes
DHCP superscopes allow a single DHCP server to serve multiple subnets, helping manage IP address allocation across segmented networks.
