1. Which DNS zone contains records that resolve IP addresses to hostnames and is named using the reverse of the network address?
Reverse lookup zones contain PTR records and are named using the reversed octets of the IP address range (e.g., 10.in-addr.arpa for 10.x.x.x).
2. Which DNS record type is used to resolve an IPv6 address to a hostname (reverse lookup for IPv6)?
PTR records in the ip6.arpa reverse lookup zone map IPv6 addresses back to hostnames, equivalent to in-addr.arpa for IPv4.

A DHCP reservation ties a specific IP address to a client's MAC address, ensuring the client always receives the same IP.
4. You deploy Network Access Protection (NAP) with IPSec enforcement. Which component issues health certificates to compliant clients?
The Health Registration Authority (HRA) receives health statements from compliant clients and requests health certificates from the CA on their behalf for IPSec-based NAP enforcement.
5. A company has multiple branch offices connected via site-to-site VPNs. Administrators need a centralized location to manage all VPN connections. Which Windows Server role should they deploy?
RRAS provides VPN gateway capabilities and can be used to establish and manage site-to-site VPN connections between branch offices.
6. A security team requests a report on all open inbound firewall rules in the Windows Server 2008 perimeter. How should the network administrator present this information for maximum clarity?
