6 What is a security feature of using NAT on a network?

allows internal IP addresses to be concealed from external users

denies all internal hosts from communicating outside their own network

allows external IP addresses to be concealed from internal users

7 A network administrator has determined that various computers on the network are infected with a worm. Which sequence of steps should be followed to mitigate the worm attack?

9 Refer to the exhibit. Baseline documentation for a small company had ping round trip time statistics of 36/97/132 between hosts H1 and H3. Today the network administrator checked connectivity by pinging between hosts H1 and H3 that resulted in a round trip time of 1458/2390/6066. What does this indicate to the network administrator?

Something is causing interference between H1 and R1.

H3 is not connected properly to the network.

Performance between the networks is within expected parameters.

Connectivity between H1 and H3 is fine.

Something is causing a time delay between the networks.

10 When should an administrator establish a network baseline?

when the traffic is at peak in the network

when there is a sudden drop in traffic

at the lowest point of traffic in the network

at regular intervals over a period of time

11 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 verify the IP address configured on router R2.

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

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

The network administrator wants to verify Layer 2 connectivity.

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