MCSE 70-297: Network Infrastructure Design 1 — Questions and Answers
Question 1: When designing an Active Directory forest structure, what is the primary reason to create multiple forests?
- To maintain separate security boundaries (Correct answer)
- To reduce replication traffic
- To support more than 1,000 users
- To enable multiple DNS namespaces
Correct answer: To maintain separate security boundaries
Separate forests provide the strongest security boundary since administrative access cannot cross forest boundaries without explicit trusts.
Question 2: Which DNS record type is required for domain controllers to be located by clients?
- SRV (Correct answer)
- A
- MX
- PTR
Correct answer: SRV
Domain controllers register SRV (Service) records in DNS so that Active Directory clients can locate services like Kerberos and LDAP.
Question 3: What is the recommended DHCP scope utilization threshold that should trigger adding a new scope or server?
- 80% (Correct answer)
- 50%
- 95%
- 100%
Correct answer: 80%
Microsoft recommends that when DHCP scope utilization reaches 80%, administrators should plan to expand the scope or deploy additional servers.
Question 4: Which Windows Server 2003 feature allows multiple network paths to be aggregated for increased bandwidth and fault tolerance?
- Network Load Balancing (NLB) (Correct answer)
- DHCP Failover
- Routing and Remote Access
- Network Bridge
Correct answer: Network Load Balancing (NLB)
Network Load Balancing distributes incoming traffic across multiple servers, providing both increased throughput and fault tolerance.
Question 5: When designing an IP addressing scheme, what class of address is 172.16.0.0/12?
- Class B private (Correct answer)
- Class A private
- Class C private
- Class B public
Correct answer: Class B private
The 172.16.0.0/12 range (172.16.0.0 to 172.31.255.255) is a Class B private address range defined by RFC 1918.
Question 6: Which protocol is used by Windows Server 2003 to dynamically update DNS records for DHCP clients?
- Dynamic DNS (DDNS) (Correct answer)
- BOOTP
- WINS
- RARP
Correct answer: Dynamic DNS (DDNS)
Dynamic DNS (DDNS) allows DHCP servers or clients to automatically register and update DNS resource records when IP addresses change.
