  B. If the priority of the R1 ISIS 5, R1 10.0.2.2/32 P OSPF protocol is adjusted to then the route entry of the destination network segment is generated.
  C. If the priority of the R1 ISIS 5, R1 10.0.2.2/32 P ISIS protocol is adjusted to then the routing entry on the destination network segment is generated.
  D. If the R2 ISIS 5, R1 10.0.2.2/32 P ISIS protocol priority level is adjusted to then the destination segment is generated by the route entry.

• Question 352:

  Which of the following statements regarding route import is false?

  A. Importing IBGP routes into the OSPF process may cause routing loops.
  B. By default, the metric of external routes imported into the OSPF process \s 1 and the type of imported external routes is Type 2.

• Question 354:

  You need to configure policy routing on the router to specify that specific traffic passes through an interface. Which two most typical classes are used when applying policy-based routing Information can be used to forward traffic along a specific path?

• Question 355:

  A Local Area Network Denial (LAND) attacker sends a SYN packet in which the source and destination addresses are the same as the target host's address and the source port is the same as the destination port. While the receiver waits for the final ACK packet from the sender, the connection is in half-connected mode, which wastes limited TCP resources at the receive end.

  B. FALSE
  A. TRUE
