Your company has four DNS servers that run Windows Server 2008 R2. Each server has a static IP address.
You need to prevent DHCP from assigning the addresses of the DNS servers to DHCP clients.
What should you do?

You have a Windows Server 2008 R2 computer that has an IP address of 172.16.45.9/21.
The server is configured to use IPv6 addressing.
You need to test IPv6 communication to a server that has an IP address of 172.16.40.18/21.
What should you do from a command prompt?

Your company has computers in multiple locations that use IPv4 and IPv6. Each location is protected by a firewall that performs symmetric NAT.
You need to allow peer-to-peer communication between all locations.
What should you do?

Your company uses DHCP to lease IPv4 addresses to computers at the main office. A WAN link connects the main office to a branch office. All computers in the branch office are configured with static IP addresses. The branch office does not use DHCP and uses a different subnet. You need to ensure that the portable computers can connect to network resources at the main office and the branch office.
How should you configure each portable computer?

Your company is designing its network. The network will use an IPv6 prefix of 2001:DB8:BBCC:0000::/53.
You need to identify an IPv6 addressing scheme that will support 2000 subnets.
Which network mask should you use?

Your company has an IPv6 network that has 25 segments. You deploy a server on the IPv6 network. You need to ensure that the server can communicate with all segments on the IPv6 network.
What should you do?

Your network contains a server named Server1 that runs Windows Server 2008 R2. Server1 has the Routing and Remote Access service (RRAS) role service installed. You need to view all inbound VPN packets. The solution must minimize the amount of data collected.
What should you do?

Your network contains a single Active Directory domain. All servers run Windows Server 2008 R2. A DHCP server is deployed on the network and configured to provide IPv6 prefixes. You need to ensure that when you monitor network traffic, you see the interface identifiers derived from the Extended Unique Identifier (EUI)-64 address.
Which command should you run?

You need to capture the HTTP traffic to and from a server every day between 09:00 and 10:00.
What should you do?

Your network contains a server named Server1 that runs Windows Server 2008 R2. Server1 has the SNMP Service installed.
You perform an SNMP query against Server1 and discover that the query returns the incorrect identification information.
You need to change the identification information returned by Server1.
