Administering Windows Server 2012 Network Infrastructure & DNS Services 1 — Questions and Answers
Question 1: Which Windows Server 2012 role provides automatic IP address assignment and management to network clients?
- DNS Server
- DHCP Server (Correct answer)
- IPAM
- Routing and Remote Access
Correct answer: DHCP Server
The DHCP Server role automatically assigns IP addresses, subnet masks, default gateways, and DNS server addresses to network clients.
Question 2: In Windows Server 2012, what is IPAM used for?
- Managing Internet proxy settings
- Centrally monitoring and managing IP address space, DHCP, and DNS (Correct answer)
- Configuring IPsec tunnels
- Auditing IP-level firewall rules
Correct answer: Centrally monitoring and managing IP address space, DHCP, and DNS
IP Address Management (IPAM) provides a centralized framework for monitoring, auditing, and managing the IP address space along with associated DHCP and DNS infrastructure.
Question 3: What type of DNS record maps a hostname to an IPv6 address in Windows Server 2012 DNS?
- A
- AAAA (Correct answer)
- PTR
- CNAME
Correct answer: AAAA
AAAA records (quad-A) map fully qualified domain names to 128-bit IPv6 addresses, while A records map to 32-bit IPv4 addresses.
Question 4: In Windows Server 2012 DNS, what is the purpose of a stub zone?
- Cache all DNS records for a zone
- Store only the SOA, NS, and A records of an authoritative zone to resolve names in that zone (Correct answer)
- Provide secondary DNS for a zone
- Block DNS queries from external clients
Correct answer: Store only the SOA, NS, and A records of an authoritative zone to resolve names in that zone
A stub zone contains only the SOA record, NS records, and A records for the zone's name servers, helping DNS servers locate authoritative servers for a zone.
Question 5: Which feature of Windows Server 2012 DHCP helps prevent unauthorized DHCP servers from operating on the network?
- DHCP failover
- DHCP authorization in Active Directory (Correct answer)
- DHCP filtering
- DHCP relay agent
Correct answer: DHCP authorization in Active Directory
DHCP servers must be authorized in Active Directory before they can serve leases, preventing rogue DHCP servers from assigning incorrect IP configuration.
Question 6: What is the purpose of a DNS forwarder in Windows Server 2012?
- Replicate DNS zones to secondary servers
- Forward DNS queries for external names to another DNS server (Correct answer)
- Balance DNS query load across multiple servers
- Cache DNS records locally for performance
Correct answer: Forward DNS queries for external names to another DNS server
A DNS forwarder directs queries that the local DNS server cannot resolve to a designated upstream DNS server, typically an ISP or public DNS server.
