• Question 341:

  Based on BGP route selection rules, how are Origin attributes listed in descending order of priority?

  A. EGP > IGP > Incomplete
  B. IGP > Incomplete > EGP
  C. Incomplete > EGP > IGP
  D. IGP > EGP > Incomplete
  D. IGP > EGP > Incomplete

• Question 342:

  RSTP provides faster convergence than STP. What are causes? (Choose all that apply.)

  A. RSTP defines the edge port role. The edge port does not receive and process configuration BPDUs, and not participate in RSTP calculation. The edge port can directly change from the Disable state to the Forwarding state.
  B. When the root port fails, the optimal alternate port will become the root port and enter the Forwarding state.
  C. In RSTP, when a port is elected as the designated port, it enters the Discarding state. Then the port immediately enters the Forwarding state through the Proposal/Agreement mechanism.
  D. In RSTP, when a port receives RST BPDUs from the upstream designated bridge, the port will compare the own stored RST BPDU will the received RST BPDU.
  E. When the designated port fails, the optimal alternate port will become the root port and enter the Forwarding state.

• Question 344:

  An ACL is used to match routing information or data packet addresses so as to filter out the unmatched routing information or data packets.

  A. True
  B. False
  A. True

• Question 345:

  Which of the following statement about the jitter and delay is false?

  A. The jitter depends on the delay.
  B. The variation in packet delay is called jitter.
  C. The lower the delay is, the less the jitter is.
  D. The jitter is independent of the delay.
  D. The jitter is independent of the delay.

• Question 346:

  Which statement about the trunk interface is true?

  A. A trunk interface is always connected to hosts.
  B. "multiple" VLAN IDs can be set on a trunk interface. The VLAN IDs can be the same as or different from the PVID.
  C. The trunk interface cannot have a PVID.
  D. If the trunk interface receives a packet with a VLAN not in the allowed VLAN list, the trunk interface broadcast the packet in the VLAN.
  B. "multiple" VLAN IDs can be set on a trunk interface. The VLAN IDs can be the same as or different from the PVID.

• Question 347:

  What are the mainly methods of data collection? (Choose all that apply.)

  B. Collection through port mirroring
  C. Centralized collection by NMS
  D. Automatic collection
  A. Collection by physical optical splitter
  B. Collection through port mirroring
  C. Centralized collection by NMS

  B. FALSE

• Question 350:

  Which statement about OSPF is false?

  A. Hello packets are used to discover and maintain neighbor relationships. On a broadcast network or an NBMA network, Hello packets can also be used to elect a DR and a BDR.
  B. DD packets describe summary LSDB information by carrying LSA headers.
  C. The intervals at which two routers send Hello packets must be consistent; otherwise, a neighbor relationship cannot be established between them.
  D. DD packets contain headers of all LSAs for periodic LSDB synchronization between OSPF neighbors.
  D. DD packets contain headers of all LSAs for periodic LSDB synchronization between OSPF neighbors.
