Which of the following statements regarding the BGP error display of a router false?

An edge port is a new port role added to RSTP to overcome the disadvantages of STP. Which of the following statements is false about this port role?

On an IS-IS network, each router can generate LSPs. Which of the following events trigger the generation of a new LSP?

Which of the following statements regarding BGP route advertisement are false?

An enterprise office network runs OSPF and is divided into multiple OSPF areas. Enterprise network engineers can configure route summarization on ASBRs to reduce the number of inter-area Type 3 LSAs, which in turn reduces the routing table size and improves device resource utilization.

A monitoring plane usually comprises the monitoring units of main control boards and interface boards. This plane can monitor the system environment independently. Which of the following environment monitoring functions can be provided by the monitoring plane?

Which of the following statements is true about BGP?

On an OSPF network, if two routers with the same router ID run in different areas and one of the routers is an ASBR, LSA flapping occurs.

As shown in the figure, the stateful inspection firewall forwards the packet because the packet matches the session status of the firewall.

Four routers run ISIS and have established adjacencies. The area IDs and router levels are marked in the following figure. If route leaking is configured on R3, which of the following is the cost of the route from R4 to 10.0.2.2/32?

As shown in the figure, R1 imports the direct route 10.1.1.0/24 to OSPF. An engineer enables bidirectional route re-advertisement on R2 and R3, and configures the following commands on R3. After the network becomes stable, which of the following is the Pre value of the route 10.1.1.0/24 in the routing table of R4?

[R3]acl 2000
[R3-acl-basic-2000] rule permit source 10.1.1.0 0
[R3-acl-basic-2000] quit
[R3]route-policy hcip permit node 10
[R3-route-policy-10] if-match acl 2000
[R3-route-policy-10] apply preference 14
[R3-route-policy-10] quit
[R3]ospf 1
[R3-ospf-1] preference ase route-policy hcip

A large number of routes typically exist in a BGP routing table, and transmitting such extensive routing information brings a heavy burden to a device. In order to address this problem, it is necessary to filter those routes to be advertised. You can configure a device to advertise only necessary routes or those that its peers require.

IGMPv2 uses the timeout mechanism for group members leaving a group. Group members can only leave a group silently. Before the timeout period expires, multicast traffic is still forwarded by the multicast router, and this is a defect.

A wide area network (WAN) is a remote network that connects local area networks (LANs) or metropolitan area networks (MANs) in different areas for communication purposes. It is typically used to interconnect campus networks or data center networks.

There are two BFD operating modes. In_______mode, the local end sends BFD Control packets at specified intervals, and the remote end checks whether the local end periodically sends BFD Control packets. (Use lowercase letters.)
