R&S Final Exam Part II/ Ch 10

Which set of commands will configure a router as a DHCP server that will assign IPv4 addresses to the 192.168.100.0/23 LAN while reserving the first 10 and the last addresses for static assignment?

• ip dhcp excluded-address 192.168.100.1 192.168.100.10

  ip dhcp excluded-address 192.168.100.254

  ip dhcp pool LAN-POOL-100

  network 192.168.100.0 255.255.255.0

  ip default-gateway 192.168.100.1

• ip dhcp excluded-address 192.168.100.1 192.168.100.10

  ip dhcp excluded-address 192.168.101.254

  ip dhcp pool LAN-POOL-100

  network 192.168.100.0 255.255.254.0

  default-router 192.168.100.1

• dhcp pool LAN-POOL-100

  ip dhcp excluded-address 192.168.100.1 192.168.100.9

  ip dhcp excluded-address 192.168.100.254

  network 192.168.100.0 255.255.254.0

  default-router 192.168.101.1

• ip dhcp excluded-address 192.168.100.1 192.168.100.9

  ip dhcp excluded-address 192.168.101.254

  ip dhcp pool LAN-POOL-100

  ip network 192.168.100.0 255.255.254.0

  ip default-gateway 192.168.100.1

Which command, when issued in the interface configuration mode of a router, enables the interface to acquire an IPv4 address automatically from an ISP, when that link to the ISP is enabled?

• ip dhcp pool

• ip address dhcp

• service dhcp

• ip helper-address

Refer to the exhibit. Based on the output that is shown, what type of NAT has been implemented?

• dynamic NAT with a pool of two public IP addresses

• PAT using an external interface

• static NAT with one entry

• static NAT with a NAT pool

Refer to the exhibit. An administrator is trying to configure PAT on R1, but PC-A is unable to access the Internet. The administrator tries to ping a server on the Internet from PC-A and collects the debugs that are shown in the exhibit. Based on this output, what is most likely the cause of the problem?

• The address on Fa0/0 should be 64.100.0.1.

• The NAT source access list matches the wrong address range.

• The inside global address is not on the same subnet as the ISP.

• The inside and outside NAT interfaces have been configured backwards.

A network engineer is interested in obtaining specific information relevant to the operation of both distribution and access layer Cisco devices. Which command provides common information relevant to both types of devices?

• show ip protocols

• show ip interface

• show cdp neighbors

• show port-security

What are two functions provided by the syslog service? (Choose two.)

• to gather logging information for monitoring and troubleshooting

• to select the type of logging information that is captured

• to periodically poll agents for data

• to provide statistics on packets that are flowing through a Cisco device

When a customer purchases a Cisco IOS 15.0 software package, what serves as the receipt for that customer and is used to obtain the license as well?

• Software Claim Certificate

• End User License Agreement

• Unique Device Identifier

• Product Activation Key

Refer to the exhibit. The network administrator enters these commands into the R1 router:

R1# copy running-config tftp

Address or name of remote host [ ]?

When the router prompts for an address or remote host name, what IP address should the administrator enter at the prompt?

• 192.168.9.254

• 192.168.10.1

• 192.168.10.2

• 192.168.11.252

• 192.168.11.254

A ping fails when performed from router R1 to directly connected router R2. The network administrator then proceeds to issue the show cdp neighbors command. Why would the network administrator issue this command if the ping failed between the two routers?

• The network administrator wants to determine if connectivity can be established from a non-directly connected network.

• The network administrator wants to verify the IP address configured on router R2.

• The network administrator wants to verify Layer 2 connectivity.

• The network administrator suspects a virus because the ping command did not work.

Which statement is true about CDP on a Cisco device?​

• Because it runs at the data link layer​, the CDP protocol can only be implemented in switches.

• CDP can be disabled globally or on a specific interface​.

• To disable CDP globally, the no cdp enable command in interface configuration mode must be used.

• The show cdp neighbor detail command will reveal the IP address of a neighbor only if there is Layer 3 connectivity​.
