NO.19 When two routers exchange LSDB information using DD packets, a master/slave relationship is formed first, the router with a larger router ID is the master, and determine the MS bit.

TRUE

FALSE

NO.20 If a router ID is configured in both the system via and the BGP view, BGP uses the router ID configured in the BGP view because the BGP view takes precedence over the system view.

TRUE

FALSE

NO.21 In the OSPF protocol, inter-area route calculation involves only Router LSA, Network LSA, and Summary LSA.

TRUE

FLASE

NO.22 Which of the following statements regarding BGP route advertisement are false?

All the BGP routes learned from all BGP peer will be advertised to other BGP peers.

Only the optimal routes preferred by BGP can be advertised to other BGP peers.

By default, the routes learned from an IBGP peer will not be forwarded to other IBGP peers.

Only the routes learned from IGPs can be advertised to other BGP peers.

NO.23 Which of the following statement regarding the display ospf peer command output is true?

Address: 10.1,1.1 Indicates that the local interface address is 10.1.1.1.

Through negotiation during DD packet exchange, the local end becomes the slave.

NO.25 RSTP provides different functions in different scenarios. Which of the following statements Is false?

After TC-BPDU attack defense function is enabled, you can set the number of times the switch processes TC BPDUs within a certain period

The role of the designated port that is enabled with root protection cannot be changed

If the edge port on the switch enabled with BPDU protection receives RST BPDU, the switch sets the edge port as a non-edge-port and triggers STP calculation

When the designated port enabled with root protection receives optimal RST BPDUs, the port enters the Discarding state and does not forward packets. If the port does not receive optimal RST BPDUs within a certain period of time, the port will automatically restore to the Forwarding state

TRUE

FALSE

LS Ack packets contain complete LSA information.

DD packets contain only LSA summary information, including LS Type, LS ID, Advertising Router, and LS Sequence Number.

LS Update packets contain complete LSA information.

NO.29 After which of the following parameters are modified does an IS-IS neighbor relationship need to re-established?
