MAC addresses? (Choose two.)
neighbor solicitations
echo requests
neighbor advertisements
echo replies
,router solicitations
router advertisements
Answer: neighbor solicitations

●● Which range of link-local addresses can be assigned to an IPv6-
enabled interface?
FEC0::/10
FDEE::/7
FE80::/10
FF00::/8
Answer: FE80::/10
●● What would be the interface ID of an IPv6 enabled interface with a
MAC address of 1C-6F-65-C2-BD-F8 when the interface ID is
generated by using the EUI-64 process?
0C6F:65FF:FEC2:BDF8
1E6F:65FF:FEC2:BDF8
C16F:65FF:FEC2:BDF8
106F:65FF:FEC2:BDF8
Answer: 1E6F:65FF:FEC2:BDF8
,●● An organization is assigned an IPv6 address block of
2001:db8:0:ca00::/56. How many subnets can be created without using
bits in the interface ID space?
256
512
1024
4096
Answer: 256
●● Refer to the exhibit. If host A sends an IP packet to host B, what will
the destination address be in the frame when it leaves host A?
DD:DD:DD:DD:DD:DD
172.168.10.99
CC:CC:CC:CC:CC:CC
172.168.10.65

●● When a switch configuration includes a user-defined error threshold
on a per-port basis, to which switching method will the switch revert
when the error threshold is reached?
, cut-through
store-and-forward
fast-forward
fragment-free
Answer: store-and-forward
●● Which two statements are correct about MAC and IP addresses
during data transmission if NAT is not involved? (Choose two.)
Destination IP addresses in a packet header remain constant along the
entire path to a target host.
Destination MAC addresses will never change in a frame that goes
across seven routers.
Every time a frame is encapsulated with a new destination MAC
address, a new destination IP address is needed.
Destination and source MAC addresses have local significance and
change every time a frame goes from one LAN to another.
A packet that has crossed four routers has changed the destination IP
address four times.
Answer: Destination IP addresses in a packet header remain constant
along the entire path to a target host.
Destination and source MAC addresses have local significance and
change every time a frame goes from one LAN to another.
●● What is one main characteristic of the data link layer?
