NEW QUESTION 306

The authentication modes supported by Huawei routers can be divided into Null, Simple., MD5, and HMAC-MD5 according to different encryption algorithms. Some devices also support HMAC-SHA256

The OSPF neighbor authentication process is completed by exchanging Hello packets

Huawei routers support two authentication methods: area authentication and interface authentication

In the same OSPF process on the same router, if Area 0 uses MD5 authentication, other areas must also use MD5 authentication, but the authentication keys in different areas can be different

NEW QUESTION 307

NEW QUESTION 310
When dual-link hot backup is configured in a WLAN group, the AP will establish CAPWAP links with the primary AC and backup AC respectively.

TRUE

FALSE

NEW QUESTION 311

TRUE

FALSE

NEW QUESTION 312
ASPF technology enables the firewall to support multi-channel protocols such as FTP, and can also formulate corresponding security policies for complex applications.

TRUE

FALSE

NEW QUESTION 313
Similar to 0SPF, the two routers establishing a BGP peer relationship must be directly connected.

TRUE

FALSE

NEW QUESTION 314
IPv6 nodes need to maintain a neighbor table, and each neighbor has a corresponding state.
Which of the following statements about neighbor status is correct?

When the neighbor status is Reachable, it means that the neighbor is reachable within the specified time, but if the appearance is not used after a fixed time, the neighbor status will be migrated to Incomplete.

When the neighbor state is Incomplete, it means that the neighbor is unreachable and address resolution is in progress. When the resolution is successful, it enters the Complete state.

When the state of the neighbor is State, the NS message will be sent to the neighbor again. If a response is received, the state of the neighbor will be transferred to Incomplete.

When the neighbor status is Delay, if there is a response from the neighbor within a fixed time, the neighbor status will directly migrate to Reachable.

NEW QUESTION 315
The statement about OSPF AS-External-LSA, which is correct? (Multiple choice)

Net mask is set to all 0

Link State ID is set as the destination network segment address

Advertising Router is set to the Router ID of ASBR

Use Link State ID and Advertising Router to uniquely identify an AS-External-LSA
