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?

Question 392

(0)

ABRs of a Stub area do not flood Type-5 and Type-4 LSAs to the Stub area. Therefore, the Stub area does not have the external AS routing capability. ABRs of the Stub area advertise a default route t

Question 393

(0)

Assume that the subnet mask is 255.255.255.248. Which of the following addresses are valid host addresses? (Choose three.)

Question 394

(0)

Which of the following statements is false?

Question 395

(0)

If the Router Priority of a router is set to 0, this router cannot be elected as a DR or a BDR.

Question 396

(0)

Only Router-LSAs and Network-LSAs are involved in intra-area route calculations.

Question 397

(0)

Which of the following statements about Flush packets in a Smart Link group are true? (Choose three.)

Question 398

(0)

Which of the following statements about Stub areas is false?

Question 399

(0)

Each router running OSPF has a router ID. A router ID is a 32-bit integer and uniquely identifies a router. Hence, even of routers in different ASs, the router IDs must be different.

Question 400

Which of the following statements about link aggregation are true? (Choose three.)

Question 391

Which of the following is the possible cause?

Router IDs conflict.

Area IDs are mismatched.

Network masks are inconsistent.

Authentication passwords are inconsistent.

Question 394

Which of the following statements is false?

An ABR maintains an LSDB for each area. There are many LSDBs on an ABR.

The metric of an ASE LSA can be specified when an external route is imported. The default value is 1.

The external routing information carries a Tag label for transmitting additional information of the route. It is commonly used in a routing policy. The default value of the Tag label is 0.

The Link State ID in an ASBR-Summary-LSA is the Router ID of the ASBR.

Question 397

Which of the following statements about Flush packets in a Smart Link group are true? (Choose three.)

A Smart Link group sends Flush packets to instruct other devices to update the address table.

Flush packets use IEEE 802.3 encapsulation.

The destination MAC address of Flush packets is an unknown unicast address, which is used to distinguish protocols.

The destination MAC address of Flush packets is a special multicast address, which is used to distinguish protocols.

Question 398

Which of the following statements about Stub areas is false?

The difference between a Stub area and a Totally Stubby area is that the Totally Stubby area cannot contain summary-LSAs.

The ABR in the Stub area generates a default route to guide forwarding of packets destined for other area.

A Transit area cannot be configured as a Stub area.

Any Stub area can be configured as a Totally Stubby area.

Question 400

Which of the following statements about link aggregation are true? (Choose three.)

Link aggregation can be performed in manual load balancing or LACP mode. In manual loading balancing mode, LACP is enabled; in LACP mode, LACP is enabled too.

In manual load balancing mode, all active member interfaces forward data and perform load balancing.

In static LACP mode, the creation of the Eth-Trunk and the addition of member interfaces to the Eth-Trunk are performed manually. Compared with link aggregation in manual load balancing mode, active interfaces in static LACP modeare selected by sending LACP Data Units (LACPDUs).

In dynamic LACP mode, the creation of the Eth-Trunk, the addition of member interfaces, and the selection of active interfaces are performed based on LACP negotiation.
