• Question 271:

  Which of the following statements are correct regarding VRRP?

  A. Only Master can process the data packets sending to virtual router.
  B. Only Slave can process the data packets sending to virtual router.
  C. Both Master and Slave can process the data packets sending to the same virtual router to realize load balance.
  D. By default, only Master can process the data packets sending to virtual router; but we can do some configuration to make the Slave process the data packets sending to virtual router.
  A. Only Master can process the data packets sending to virtual router.

• Question 272:

  Which of the following statements regarding join member interfaces are false when link aggregation works in manual mode?

  A. An Eth-Trunk cannot be nestled, and a member interface cannot be an Eth-Trunk.
  B. An Ethernet interface can join only one Eth-Trunk. Before adding an Ethernet interface to an Eth-Trunk, ensure that the Ethernet interface does not belong to any other Eth-Trunk.
  C. If the local device uses the Eth-Trunk, the remote interface directly connected to the member interface must join the Eth-Trunk so that both ends can communicate.
  D. An Eth-Trunk can work in Layer 2 or Layer 3 mode. The two working modes can be identified automatically and do not need to be switched manually.
  D. An Eth-Trunk can work in Layer 2 or Layer 3 mode. The two working modes can be identified automatically and do not need to be switched manually.

• Question 273:

  Which of the following is the address range assigned by IANA for SSM service in IPv4?

  A. 232.0.0.0/24
  B. 225.0.0.0/8
  C. 232.0.0.0/8
  D. 239.0.0.0/8
  D. 239.0.0.0/8

• Question 274:

  An OSPF neighbor relationship fails to be established and the display ospf error command output is as follows.

  

  Which of the following is the possible cause?

  A. Router IDs conflict.
  B. Area IDs are mismatched.
  C. Network masks are inconsistent.
  D. Authentication types are inconsistent.
  C. Network masks are inconsistent.

• Question 275:

  OSPF supports multiple network types. Which of the following network types require DR and BDR to be elected? (Choose all that apply.)

  A. P2P
  B. NBMA
  C. P2MP
  D. Broadcast
  B. NBMA
  C. P2MP
  D. Broadcast

• Question 276:

  Which statement about ARP proxy is false?

  A. The ARP proxy, namely, the gateway, sends ARP request for the host. The MAC address in the ARP request packet is the MAC address of the host.
  B. The ARP proxy, namely, the gateway, sends ARP request for the host. The MAC address in the ARP request packet is the MAC address of its own interface.
  C. ARP proxy is also called promiscuous ARP or ARP hack.
  D. The ARP proxy allows the hosts on the networks with the same network ID to communicate with each other.
  A. The ARP proxy, namely, the gateway, sends ARP request for the host. The MAC address in the ARP request packet is the MAC address of the host.

• Question 277:

  Which BGP attributes can be used to prevent routing loops? (Choose three.)

  A. Originator_ID
  B. Aggregator
  C. Cluster_List
  D. AS-Path
  A. Originator_ID
  C. Cluster_List
  D. AS-Path

• Question 278:

  Which of the following statements about the mVRRP backup group are true? (Choose three.)

  

  A. An mVRRP backup group can be bound to other service VRRP backup groups.
  B. An mVRRP backup group cannot be bound to multiple service VRRP backup groups but can function as a service VRRP group to be bound to another mVRRP group.
  C. After a VRRP backup group member is bound to an mVRRP backup group, the state machine of the VRRP backup group member becomes dependent. That is, the VRRP backup group member deletes the protocol timer, and no longer sends or receives packets, and implements its state machine by directly copying the status of the mVRRP backup group.
  D. A VRRP backup group member can be bound to only one mVRRP backup group.
  A. An mVRRP backup group can be bound to other service VRRP backup groups.
  C. After a VRRP backup group member is bound to an mVRRP backup group, the state machine of the VRRP backup group member becomes dependent. That is, the VRRP backup group member deletes the protocol timer, and no longer sends or receives packets, and implements its state machine by directly copying the status of the mVRRP backup group.
  D. A VRRP backup group member can be bound to only one mVRRP backup group.

• Question 279:

  Fast detection technology can rapidly detect communication faults between neighboring devices as soon as possible so that the system can take measures immediately to ensure that services are not interrupted.

  A. True
  B. False
  A. True

• Question 280:

  BGP is an exterior gateway protocol which runs between ASs. It focuses on the control of route propagation and selection of optimal routes rather than discovery and calculation of routes.

  A. TRUE
  B. FALSE
  A. TRUE
