Question 101

Regarding multi-instance CE (Multi-VPN-Instance CE, MCE), which of the following description is wrong?

  1. On the MCE device, you need to create separate routing and forwarding tables for different VPNs, and bind them to the correct interface
  2. Users connected to the same MCE but not belonging to a VPN instance cannot access each other
  3. Devices with MCE function can access multiple VPN instances in BGPIMPLS IP VPN applications, reducing user investment in network equipment
  4. There must be multiple physical links between MCE and PE to achieve isolation between different VPIN instances

Question 102

In an MPLS network, there are different types of operations for labels, among which the meaning of the "pop" action is?

  1. Replace the top label with another value
  2. Add the top label to the MPLS label stack
  3. Replace the top label with another set of labels
  4. Remove the top label from the MPLS label stack

Question 103

In a multi-level RR scenario, a large number of second-level RR are connected to the first-level RR, which may cause the BGP routing table of the first-level RR to overflow. What method can be used to reduce the risk of overflow of the BGP routing table of the first-level RR?

  1. ORF
  2. Route aggregation
  3. Routing control
  4. Set the same Cluster-lD

Question 104

Which of the following tools cannot be used to match BGP routing entries?

  1. Community Filter
  2. Advanced ACL
  3. Basic ACL
  4. IP Prefix List

Question 105

Regarding the difference between NSR and NSF, which one is correct?

  1. NSF does not need neighbor routers to complete
  2. NSR must rely on neighbor routers to complete
  3. NSF must rely on neighbor routers to complete
  4. Both NSR and NSF need neighbor routers to complete
