1. If no metric is specified for the routes being redistributed into IS-IS, what metric value is assigned to the
routes?
A. 0
B. 1
C. 10
D. 20
Answer:A
2. Which three restrictions apply to OSPF stub areas? (Choose three.)
A. No virtual links are allowed.
B. The area cannot be a backbone area.
C. Redistribution is not allowed unless the packet is changed to a type 7 packet.
D. The area has no more than 10 routers.
E. No autonomous system border routers are allowed.
F. Interarea routes are suppressed.
Answer: ABE
5. Which three IP multicast related statements are true? (Choose three.)
A. Multicast addresses 224.0.1.0 through 238.255.255.255 are called globally scoped addresses. They
are used to multicast data between organizations and across the Internet.
B. The multicast address 224.0.0.1 is a globally scoped address that has been reserved for the Network
Time Protocol (NTP) by the IANA.
C. Multicast addresses 239.0.0.0 through 239.255.255.255 are called limited scope addresses. They are
constrained to a local group or organization.
D. Multicast addresses 224.0.0.5 and 224.0.0.6 are limited scoped addresses that have been reserved for
OSPF.
E. Multicast addresses 224.0.0.0 through 224.0.0.255 are used for network protocols on local LAN
segments. Because they are always transmitted with a Time to Live (TTL) of 1, they are never forwarded
by a router.
Answer:ACE
6. Which three IP multicast address related statements are true? (Choose three.)
A. Multicast addresses 224.0.0.0 through 224.0.0.255 are always forwarded because they are transmitted
with Time to Live (TTL) greater than 1.
B. Multicast addresses 224.0.0.5 and 224.0.0.6 are source multicast addresses for OSPF routers.
C. Multicast addresses 224.0.0.13 and 224.0.0.22 are reserved link-local addresses used by PIMv2 and
IGMPv3.
D. Because they would map to overlapping IP multicast MAC addresses, multicast addresses 224.0.1.1
and 238.1.1.1 could not be used together.
E. Multicast address 224.0.1.1 has been reserved for the Network Time Protocol (NTP) by the IANA.
F. The administratively scoped multicast addresses 239.0.0.0 through 239.255.255.255 are similar in
purpose to RFC 1918 private unicast addresses.
Answer: CEF
7. Which three IP multicast group concepts are true? (Choose three.)
A. If a packet is sent to a multicast group address, all members of the multicast group will receive it.
B. If a packet is sent to a multicast group address, the multicast frame contains the source multicast
address.
C. A router does not have to be a member of a multicast group to receive multicast data.
D. A router does not have to be a member of a multicast group to send to the group.
E. A router must be a member of a multicast group to receive multicast data.
F. A router must be a member of a multicast group to send to the group.
Answer: ADE
8. Which two multicast protocol statements are true? (Choose two.)
A. Dense mode multicast requires explicit join messages from their members.
B. Dense mode multicast uses a push model to flood traffic throughout the network and then prunes the
unwanted traffic.
C. Sparse mode multicast uses a pull model to send multicast traffic to where it is requested.
D. Sparse mode uses reverse path forwarding (RPF) to prune off redundant flows.
E. The primary use of sparse mode multicast is for test labs and router performance testing.
Answer:BC
