B. an IP address that is unique for each destination in the group
C. a group address that shares the last 23 bits with the source IPv4 address
D. a 48 bit address that is determined by the number of members in the multicast group
Correct answer: A

A. drop the frame
B. process the frame as it is
C. send an error message to the sending device
D. add random data bytes to make the frame 1518 bytes long and then forward it

Question 3

A. source MAC address
B. source IP address
C. destination MAC address
D. Ethernet type
E. destination IP address
Correct answer: C
Question 4

A. It initiates an ARP request.
B. It broadcasts the frame out of all ports on the switch.
C. It notifies the sending host that the frame cannot be delivered.
D. It forwards the frame out of all ports except for the port at which the frame was received.
Correct answer: D
Question 5
What are two features of ARP? (Choose two.)
If a host is ready to send a packet to a local destination device and it has the IP address but not the MAC address of the destination, it generates an ARP broadcast.
A. An ARP request is sent to all devices on the Ethernet LAN and contains the IP address of the destination host and its multicast MAC address.
B. When a host is encapsulating a packet into a frame, it refers to the MAC address table to determine the mapping of IP addresses to MAC addresses.
C. If no device responds to the ARP request, then the originating node will broadcast the data packet to all devices on the network segment.
D. If a device receiving an ARP request has the destination IPv4 address, it responds with an ARP reply.
Correct answer: AE

C. user data segmentation
D. reliable end-to-end delivery
Correct answer: A
Question 8
What is the valid most compressed format possible of the IPv6 address 2001:0DB8:0000:AB00:0000:0000:0000:1234?
A. 2001:DB8:0:AB00::1234
B. 2001:DB8:0:AB::1234
