Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q244-Q249):

NEW QUESTION # 244
Which of the following descriptions of OSPF's own anti-environment measures are correct? (Multiple choice)

A. Routers in the same area calculate a loop-free shortest path tree with itself as the root based on LSDB.
B. ASBR is not allowed to exist in the OSPF backbone area
C. When OSPF divides areas, it stipulates that all non-backbone areas must be directly connected to the backbone area, and communications between non- backbone areas must pass through the backbone area.
D. Only one ABR is allowed between the OSPF backbone area and non-backbone area.
E. OSPF's LSA flooding has a maximum of 16 hops. If it exceeds 16 hops, the LSA will be discarded.

Answer: A,C

NEW QUESTION # 245
Which of the following descriptions about VRRP is incorrect?

A. When two routers with the same priority compete for Master at the same time, the one with the larger interface address is preferred as Master.
B. VRRP priority determines the status of each router in the virtual router based on priority.
C. By default, if a Master already exists, for the sake of network stability, the Backup with a higher priority will not preempt.
D. If the Backup router works in non-preemptive mode, as long as the Master router does not fail, the Backup router will not become the Master router even if it is subsequently configured with a higher priority.

Answer: C

NEW QUESTION # 246
Which of the following descriptions about setting Community through routing policies to affect routing selection is wrong?

A. It cannot be affected, because the Community attribute of the route is a non-transitional attribute and cannot be passed between routers
B. It can be indirectly affected. By setting the Community attribute of the route, the route can be classified, and then set different route selection-related attributes according to the category, such as Local_Pre, MED, etc., to achieve the purpose of affecting route selection
C. After the router receives the routing update whose Commmity attribute is No_ Advertise, it will not advertise it outside the local AS.
D. It can be affected indirectly. By setting the Community attribute of the route, the route can be classified, and then different attributes related to route selection can be set according to the category.
These attributes only include Loacal_Pre and MED, so as to achieve the purpose of affecting route selection

Answer: B

NEW QUESTION # 247
On an OSPF network, if a router receives an update of an LSA that exists in the local LSDB, the router updates the LSDB and floods the LSA.

A. TRUE
B. FALSE

Answer: B

Explanation:
If a router receives an LSA identical to one already in its LSDB, it does not flood the LSA again unless the LSA has changed (i.e., the sequence number or content has been updated). OSPF ensures efficient use of bandwidth by avoiding redundant flooding of unchanged LSAs.

NEW QUESTION # 248
ip ip-prefx List1 index 10 permit 10.1.0.0 24 greater-equal () less-equal 32 means that the first 24 bits of the matching network address are the same as 10.1.0.0, and the network mask length is greater than or equal to 26 and less than or equal to 32 routing.

Answer:

Explanation:
26
