  STP Topology

  On a network running STP, a device is called a bridge. Each bridge has a bridge ID (BID). According to IEEE 802.1d, a BID is composed of a bridge priority (leftmost 16 bits) and a bridge MAC address (rightmost 48 bits).

• Question 772:

  Which of the following are features of the OSPF protocol?

  A. Routing loops are likely to occur.

  B. Triggered update is supported.

  C. The shortest path is calculated based on the number of hops.

  D. Area division is supported.

  Correct Answer: D

  A. True

  B. False

  Correct Answer: A

• Question 774:

  Which of the following statements about the routing table show in the figure are true?

  

  A. The next hop in the route to the destination network 10.0.3.3/32 is not directly connected. Therefore, the local router does not forward data packets destined for 10.0.3.3.

  B. The local router forwards data packets destined for 10.0.3.3 from Ethernet0/0/0.

  C. The local router forwards data packets destined for 10.0.2.2 from Erthernet0/0/0.
