Refer to the exhibit. What function does router RT_A need to provide to allow Internet access for hosts
in this network? Correct Answer: address translation
What is true regarding network layer addressing? (Choose three.) Correct Answer: It uses a hierarchical
structure.;
uniquely identifies each host;

Refer to the exhibit. Host A attempts to establish a TCP/IP session with host C. During this attempt, a
frame was captured with the source MAC address 0050.7320.D632 and the destination MAC address
0030.8517.44C4. The packet inside the captured frame has an IP source address 192.168.7.5, and the
destination IP address is 192.168.219.24. At which point in the network was this packet captured?
Correct Answer: Leaving Dallas

type of password would require this login and be considered the most secure? Correct Answer: enable
secret
Refer to the exhibit. A technician is working on a network problem that requires verification of the
router LAN interface. What address should be pinged from this host to confirm that the router interface
is operational? Correct Answer: 192.168.254.1
Which OSI layer does IP rely on to determine whether packets have been lost and to request
retransmission? Correct Answer: transport
When connectionless protocols are implemented at the lower layers of the OSI model, what is usually
used to acknowledge that the data was received and to request the retransmission of missing data?
Correct Answer: an upper-layer, connection-oriented protocol or service
, Refer to the exhibit. Host C is able to ping 127.0.0.1 successfully, but is unable to communicate with
hosts A and B in the organization. What is the likely cause of the problem? Correct Answer: The subnet
mask on host C is improperly configured.
Refer to the exhibit. Which list refers only to end devices? Correct Answer: D,E,F,G
Refer to the exhibit. Host A sends a frame with the destination MAC address as FFFF.FFFF.FFFF. What
action will the switch take for this frame? Correct Answer: It will send the frame to all hosts except host
A.
Which subnet mask will allow 2040 hosts per subnet on the IP network 10.0.0.0? Correct Answer:
255.255.248.0
Refer to the exhibit. RouterB is configured properly. The Ethernet interface Fa0/0 of RouterA is
configured with the use of the commands that are shown. However, a ping from the Fa0/0 interface of
RouterA to the Fa0/0 interface of RouterB is unsuccessful. What action should be taken on RouterA to
solve this problem? Correct Answer: Use the no shutdown command on the FastEthernet interface
Fa0/0.
To send data through a network, what two flags are used to establish a session? (Choose two.) Correct
Answer: ACK;
SYN
Which statement is true about the TTL value of an IPv4 packet? Correct Answer: It specifies the
remaining "life" of the packet.
Refer to the exhibit. Communication for hosts X and Y is restricted to the local network. What is the
reason for this? Correct Answer: The gateway addresses are broadcast addresses.
What type of network is maintained if a server takes no dedicated role in the network? Correct Answer:
peer-to-peer
