• Question 143:

  Which of the following is the port state defined by RSTP?

  A. Discarding
  B. Learning
  C. Forwarding
  D. All of the above

• Question 144:

  Which of the following statements are correct regarding priority in VRRP?

  A. The IP address owner always uses 255 as its priority regardless its config priority.
  B. The IP address owner always uses 0 as its priority regardless its config priority.
  C. We can configure the priority as 0 to make the router never attend the Master election.
  D. If a VRRP router changes from Master to Slave, it will send out a VRRP message with priority 0 in the network.
  A. The IP address owner always uses 255 as its priority regardless its config priority.

• Question 145:

  Which of the following statements about VRRP are true? (Choose three.)

  A. VRRP is a redundancy protocol designed for a multicast- or broadcast-capable LAN such as the Ethernet. VRRP ensures that traffic is switched to another router when the next-hop router for a host on the LAN fails. This guarantees the reliability and non-stop forwarding of services.
  B. In VRRP, two virtual router ID and a virtual IP address need to be configured on a router to generate a virtual MAC address. A virtual router is formed.
  C. Hosts on a network can communication with a virtual router without knowing any information about physical routers on the network.
  D. A virtual router consists of a master router and several backup routers. The master router forwards packets. When the master router fails, a backup router takes over as the master router.

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

• Question 147:

  What is the link ID of an ASBR-Summary-LSA?

  C. Address of the destination network segment
  D. Router ID of the destination ASBR
  D. Router ID of the destination ASBR

• Question 148:

  C. eSight displays the architecture of the entire network and relationship between network entities.
  D. The physical topology monitoring provides an entry for unified network monitoring, improving OandM efficiency.
