Question 1

An administrator needs to configure Windows Server 2008 R2 to route traffic between two subnets without using a dedicated hardware router. Which feature should be enabled?

Accepted Answer

IP Routing via Routing and Remote Access (RRAS)

Answer

Enabling IP routing in RRAS allows Windows Server 2008 R2 to function as a software router between subnets.

Question 2

Which Windows Server 2008 R2 feature provides fault tolerance for a DHCP server by splitting scope address distribution between two DHCP servers?

Accepted Answer

DHCP Failover (80/20 rule)

Answer

The 80/20 rule manually splits a scope so that 80% of addresses are served by the primary and 20% by a backup DHCP server.

Question 3

A Windows Server 2008 R2 DNS server is configured as a forwarder. When the forwarder is unavailable, which behavior occurs by default if 'Use root hints if no forwarders are available' is enabled?

Accepted Answer

The DNS server queries root hint servers to resolve the name

Answer

With root hints fallback enabled, the DNS server falls back to iterative queries starting from root hint servers when forwarders fail.

Question 4

Which type of DNS zone stores a read-only copy of zone data and only contains NS and SOA records plus glue records for delegated zones?

Accepted Answer

Stub zone

Answer

A stub zone contains only the SOA, NS, and glue A records needed to contact authoritative servers for the zone.

Question 5

An IPsec policy is applied via Group Policy on Windows Server 2008 R2. A server cannot communicate with a client after the policy is applied. What is the most likely cause?

Accepted Answer

The client does not have a matching IPsec policy configured

Answer

IPsec requires both endpoints to have compatible policies; if the client lacks a matching policy, the negotiation fails and communication is blocked.
