Nsa Chapter 7 Exam

Topics: IP address, Network address translation, Subnetwork Pages: 5 (1290 words) Published: May 5, 2013
Refer to the exhibit. Traffic exiting R1 is failing translation. What part of the configuration is most likely incorrect? ip nat pool statement
access-list statement
ip nat inside is on the wrong interface
interface s0/0/2 should be a private IP address

Refer to the exhibit. What is the purpose of the command marked with an arrow shown in the partial configuration output of a Cisco broadband router? defines which addresses can be translated
defines which addresses are allowed into the router
defines which addresses are assigned to a NAT pool
defines which addresses are allowed out of the router

How many bits of an IPv6 address are used to identify the interface ID? 32

Refer to the exhibit. How many IPv6 broadcast domains exist in this topology? 0

Refer to the exhibit. Which two addresses could be assigned to traffic leaving S0 as a result of the statement ip nat pool Tampa netmask (Choose two.)

Refer to the exhibit. A network technician determines DHCP clients are not working properly. The clients are receiving IP configuration information from a DHCP server configured on the router but cannot access the Internet. From the output in the graphic, what is the most likely problem? The DHCP server service is not enabled.

The inside interface for DCHP is not defined.
The DHCP pool is not bound to the interface.
The pool does not have a default router defined for the clients. All the host addresses have been excluded from the DHCP pool.
Your organization is issued the IPv6 prefix of 2001:0000:130F::/48 by your service provider. With this prefix, how many bits are available for your organization to create subnetworks? 8

After activating IPv6 routing on a Cisco router and programming IPv6 addresses on multiple interfaces, what is the remaining step to activate RIPng? Enter the interface programming mode for each IPv6 interface and enable IPng RIP. Enter the ipv6 router rip name command and then use network statements to activate RIPng on the interfaces. Enter the router rip command, and then activate RIPng using the version command. RIPng then automatically runs on all IPv6 interfaces. Enter the interface programming mode for each IPv6 interface and enable the multicast group FF02::9, and then activate RIPng globally using the ipv6 router rip name command.

Refer to the exhibit. IPv6 address 2006:1::1/64 eui-64 has been configured on the router FastEthernet0/0 interface. Which statement accurately describes the EUI-64 identifier configuration? It will randomly generate a 64 bit interface ID.

It will assign an address from the pool of IPv6 private addresses to the interface. It will assign only the registry prefix of the IPv6 Global Unicast address to the interface. The configuration will derive the interface portion of the IPv6 address from the MAC address of the interface.
What is true regarding the differences between NAT and PAT?
PAT uses the word “overload” at the end of the access-list statement to share a single registered address. Static NAT allows an unregistered address to map to multiple registered addresses. Dynamic NAT allows hosts to receive the same global address each time external access is required. PAT uses unique source port numbers to distinguish between translations.

Refer to the exhibit. The FTP server has an RFC 1918 private address. Users on the Internet need to connect to the FTP server on the Fa0/0 LAN of R1. Which three configurations must be completed on R1? (Choose three.) dynamic NAT

NAT with overloading
open port 20
open port 21
open port 23
NAT with port forwarding

Refer to the exhibit. On the basis of the configuration shown, how should the pool of the excluded addresses be assigned to key hosts on the network, such as router interfaces, printers, and servers? The addresses are statically assigned by the...
