  3. RTA and RTB cannot establish a neighbor relationship
  4. A neighbor relationship can be established; all network segments are reachable
Correct answer: D
Question 2

  1. The fastest routing process
  2. uniqueness
  3. Higher preference value
  4. The route with the largest next-hop address 
  5. Low Router ID
Correct answer: C
Question 3
Which of the following statements are NOT true regarding the TCP sliding window protocol? (Multiple Choice)
  1. The initial window offer is advertised by the sender
  2. If the retransmission timer expires without the sender receiving an ACK message, the receiver retransmits the packet to the sender.
  3. The size of the sliding window can only increase or stay the same
  4. It allows the transmission of multiple frames before waiting for an acknowledgment
  5. The receiver is required to acknowledge the data packets transmitted by the sender
  6. The sender need not transmit a full window’s worth of data
Correct answer: AC

  1. FALSE
  2. TRUE
Correct answer: A
Question 6
Which types of prefixes will a router running BGP most likely advertise to an IBGP peer, assuming it is not configured as a route reflector?
  1. Prefixes received from EBGP peers and prefixes received from route reflectors
  2. All prefixes in its routing table
  3. Prefixes received from EBGP peers and prefixes locally originated via network statements or imported
  4. Prefixes received from other IBGP peers, prefixes received from EBGP peers, and prefixes imported to BGP
  5. Prefixes received from other IBGP peers and prefixes received from router reflectors
  6. Prefixes received from any other BGP peer and prefixes locally originated via network statements or imported
Correct answer: C
Question 7
In a data communication session between two hosts, the session layer in the OSI model generally communicates with what other layer of the OSI model?
  1. The physical layer of the peer 
  2. The peer’s presentation layer
  3. The peer’s session layer
  4. The peer’s application layer
  5. The data link layer of the peer
Correct answer: C
Question 8

  1. Does not advertise the route to other BGP routers
  2. Discards the route directly
  3. Advertises the route to IBGP peers only
  4. Advertises the route normally, but does not use it to forward data
Correct answer: C
