  B. The traffic path cannot be adjusted flexibly.
  C. The upgrade of new network services is slow.

• Question 176:

  When importing routes discovered by other routing protocols, a routing protocol may need to import only the routes that meet the conditions and set attributes of the imported routes to meet the requirement of the protocol. In such a case, a route-policy can be created.

  A. True

  A. True

• Question 177:

  What about all outgoing labels in the label forwarding table of a device for the same route with the same next hop?

  A. They must be different.
  B. They must be the same.
  C. They may be the same.
  B. They must be the same.

• Question 178:

  Which statements about the PVID on the access interface are true?

  A. When receiving a packet without the VLAN tag, the interface adds the VLAN tag to the packet and sets the VID in the tag to the default VLAN ID.
  B. When receiving a packet with a VLAN tag, the interface compares the VLAN ID in the tag with the default VLAN ID. If they are the same, the interface forwards the packets; otherwise, the interface discards the packets.
  C. When the interface sends a packet with a VLAN tag that contains the default VLAN ID, the system removes the VLAN tag of the packet, and then forwards the packet.
  D. None of the above.

  D. All routers on a PIM-SM network must know the location of RPs.
  A. Different group addresses on a PIM-SM network can correspond to different RPs.

  B. Link aggregation complies with IEEE 802.3az.
  C. The logical link formed by bundling multiple physical links together is called a link aggregation group (LAG) or a trunk.
  D. Active and inactive interfaces exist in link aggregation. Active interfaces forward data, whereas inactive interfaces do not.
