QUESTION 18
In computer networking a multicast address is an identifier for a group of hosts that have joined a multicast group. Multicast addressing can be used in the Link Layer (OSI Layer 2), such as Ethernet Multicast, as well as at the Internet Layer (OSI Layer
3) as IPv4 or IPv6 Multicast. Which two descriptions are correct regarding multicast addressing?
A. The first 23 bits of the multicast MAC address are 0x01-00-5E.
This is a reserved value that indicates a multicast application.
B. The last 3 bytes (24 bits) of the multicast MAC address are 0x01-00-5E.
This is a reserved value that indicates a multicast application.
C. To calculate the Layer 2 multicast address, the host maps the last 23 bits of the IP address into the last 24 bits of the MAC address. The high-order bit is set to 0.
D. The first 3 bytes (24 bits) of the multicast MAC address are 0x01-00-5E.
This is a reserved value that indicates a multicast application.
Answer: CD
QUESTION 19
EIGRP is being used as the routing protocol on the Company network. While troubleshooting some network connectivity issues, you notice a large number of EIGRP SIA (Stuck in Active) messages. What causes these SIA routes? (Select two)
A. The neighboring router stops receiving ACK packets from this router.
B. The neighboring router starts receiving route updates from this router.
C. The neighboring router is too busy to answer the query (generally caused by high CPU utilization).
D. The neighboring router is having memory problems and cannot allocate the memory to process the query or build the reply packet.
Answer: CD
Explanation:
SIA routes are due to the fact that reply packets are not received. This could be caused by a router which is unable to send reply packets. The router could have reached the limit of its capacity, or it could be malfunctioning.
Notes: If a router does not receive a reply to all outstanding queries within 3 minutes, the route goes to the stuck in active (SIA) state. The router then resets the neighbors that fail to reply by going active on all routes known through that neighbor, and it re-advertises all routes to that neighbor.
