NEW QUESTION # 325
On the OSPF network shown in the figure, an adjacency has been established between R1 and R2. An engineer configures the commands in the figure on R2. In this case, which of the following routing entries may exist in the routing table of R2?
Answer: A,C,D
Explanation:
Configuration Analysis:
* On R2, the following configuration has been applied:
acl 200
rule deny source 10.1.0.0 0.0.3.0
rule permit
#
ospf 1
filter-policy 2000 import
* This configuration uses ACL 200 to filter routes during import into the OSPF routing table on R2.
* Rule deny source 10.1.0.0 0.0.3.0: Blocks routes in the range 10.1.0.0/24 to 10.1.3.0/24 (inclusive).
* Rule permit: Allows all other routes to be imported.
* Impact of ACL 200 on Route Import:
* 10.1.0.0/24 to 10.1.3.0/24: These subnets are explicitly denied by ACL 200 and will not appear in R2's routing table.
* 10.1.4.0/24 and beyond: These subnets are permitted by the rule permit statement and will be imported into R2's routing table.
* Routing Table Entries on R2:
* Option A (10.1.4.0/24): Exists in R2's routing table because it is permitted.
* Option B (10.1.3.0/24): Does not exist because it is denied by ACL 200.
* Option C (10.1.2.0/24): Does not exist because it is denied by ACL 200.
* Option D (10.1.1.0/24): Does not exist because it is denied by ACL 200.
* A (10.1.4.0/24)
Correct Options:References:
* HCIA-Datacom Study Guide, Chapter: OSPF Route Filtering
* Huawei ACL Configuration for Route Policies
NEW QUESTION # 326
In the broadcast network shown in the figure, OSPF runs on four routers, and they are in the same area and the same network segment. OSPF will automatically elect a DR and a BDR, and the other two routers will become DR other, so as to achieve a better backup effect.
Answer: A
NEW QUESTION # 327
To prevent inter-area routing loops, OSPF does not allow advertising routing information between two non- backbone areas and allows sing routing information only within an area or between the backbone area and a non-backbone area. Therefore, each ABR must be connected to the backbone area.
Answer: A
Explanation:
OSPF (Open Shortest Path First) mandates that the backbone area (Area 0) serves as the central area for routing information exchange. To avoid inter-area routing loops, routing information is only exchanged between the backbone area and non-backbone areas, not directly between two non-backbone areas.
Consequently, each Area Border Router (ABR) must connect to the backbone area to facilitate this routing exchange .
NEW QUESTION # 328
By default, the time interval for sending PIM Hello messages on the router interface is () seconds.

Explanation:
30
NEW QUESTION # 329
