Which of the following is the primary method for transmitting IPv6 traffic over an IPv4 network? A. Subnetting B. Tunneling C. Supernetting D. Contracting |
B. Tunneling is a method for encapsulating IPv6 traffic within IPv4 datagrams |
|
|
Which of the following is the IPv6 equivalent to a private IPv4 address? A. Link-local unicast address B. Global unique unicast address C. Unique local unicast address D. Anycast address |
C. Unique local unicast addresses are the IPv6 equivalent of the 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 private network addresses in IPv4 |
|
|
Which of the following is an automatic tunneling protocol used by Windows operating systems that are located behind NAT routers? A. Teredo B. 6to4 C. ISATAP D. APIPA |
A. Teredo is a mechanism that enables devices behind non-IPv6 NAT routers to function as tunnel endpoints |
|
|
Which type of IP address must a system have to be visible from the Internet? A. Registered B. Binary C. Class B D. Subnetted |
A. For an address to be visible from the Internet, it must be registered with the IANA |
|

Which of the following subnet mask values would you use when configuring a TCP/IP client with an IPv4 address on the 172.16.32.0/19 network? A. 255.224.0.0 B. 255.240.0.0 C. 255.255.224.0 D. 255.255.240.0 E. 255.255.255.240 |
C. In binary form, the mask 255.255.224.0 is 11111111.11111111.11100000.00000000, which contains 19 network identifier bits |

|
Which of the following terms best describes the component that enables DHCP clients to communicate with DHCP servers on other subnets? A. Forwarder B. Resolver C. Scope D. Relay agent |
D. a relay agent is a software module that receives DHCP broadcast messages and forwards them to a DHCP server on another subnet |
|
|
Which of the following message types is not used during a successful DHCP address assignment? A. DHCPDISCOVER C. DHCPACK D. DHCPINFORM |
D. The DHCPINFORM message type is not used during an IP address assignment |
|
|
Which of the following DHCP address allocation types is the equivalent of a reservation in Windows Server 2012 R2? A. Dynamic allocation B. Automatic allocation C. Manual allocation D. Hybrid allocation |
C. Manual allocation is when the DHCP server permanently assigns a specific IP address to a specific computer on the network. In the Windows Server 2012 R2 DHCP server, manually allocated addresses are called reservations |
|
|
Which of the following network components are typically capable of functioning as DHCP relay agents? A. Windows 8.1 computers B. Routers C. Switches D. Windows Server 2012 R2 computers |
B. Most IP routers have DHCP relay agent capabilities built into them. If the routers connecting your subnets are so equipped, you can use them as relay agents, eliminating the need for a DHCP server on each subnet. D. If your routers cannot function as DHCP relay agents, you can use the relay agent capability built into the Windows server operating systems. In Windows Server 2012 R2, the DHCP relay agent capability is built into the Remote Access role |
|
|
Which of the following TCP/IP parameters is typically deployed as a scope option in DHCP? A. DNS Server B. Subnet Mask C. Lease Duration D. Default Gateway |
D. The default gateway must be a router on the same subnet as the IP addresses the DHCP server is allocating. Therefore, the gateway address is different for every scope and must be deployed as a scope option
|

Which of the following resource record types contains the information a DNS server needs to perform reverse name lookups? A. A B. CNAME C. SOA D. PTR |
D. PTR records contain the information needed for the server to perform reverse name lookups
|
|
|
Which of the following would be the correct FQDN for a resource record in a reverse lookup zone if the computer's IP address is 10.75.143.88? A. 88.143.75.10.in-addr.arpa B. 10.75.143.88.in-addr.arpa C. in-addr.arpa.88.143.75.10 D. arpa.in-addr.10.75.143.88 |
A. To resolve the IP address 10.75.143.88 into a name, a DNS server would locate a domain called 143.75.10.in-addr.arpa in the usual manner and read the contents of a resource record named 88 in that domain |
|
|
Which of the following is not one of the elements of DNS? A. Resolvers B. Relay agents C. Name servers D. Namespace |
B. Relay agents are router devices that enable DHCP clients to communicate with servers on other networks |
|
|
In which of the following DNS transactions does the querying system generate a recursive query? A. A DNS client sends the server name www.adatum.com to its designated DNS server for resolution B. A client's DNS server sends a request to a root domain server to find the authoritative server for the com top-level domain C. A client's DNS server sends a request to the com top-level domain server to find the authoritative server for the adatum.com domain D. A client's DNS server sends a request to the adatum.com domain server to find the IP address associated with the server name www. |
A. When a client sends a name resolution query to its DNS server, it uses a recursive request so that the server will take on the responsibility for resolving the name |
|
|
Which of the following contains the controls used to modify DNS name caching? A. The Forwarders tab of a server's properties sheet B. The State of Authority (SOA) tab of a zone's Properties sheet C. The Root Hints tab of a server's Properties sheet D. The New Zone Wizard |
B. The Start of Authority (SOA) tab of a zone's Properties sheet contains the Minimum (Default) TTL setting that controls DNS name caching for the zone |
