NEW QUESTION # 17
In the network shown in the figure, R1 and R2 are configured with single-hop BFD detection. The network engineer found that the BFD session was Down, so he queried the BFD-related configurations of R1 and R2. The configuration information has been marked in the figure.
In addition, the network engineer performed the Ping 10.0.12.2 operation on R1, and the output information is shown in the figure.
Based on this, the possible reason for the BFD session going Down is that the packets with UDP port 4784 are rejected.
Answer: A
NEW QUESTION # 18
On the network shown in the figure, EBGP peer relationships are established between neighboring routers through directly connected interfaces.
* The router ID of each router is 10.0.X.X, and the AS number is 6500X, where X is the number of the router.
* Both R1 and R4 have static routes to 192.168.1.0/24, which are imported to BGP through the import- route command.
* R1 adds a community attribute (1:1) to the route before advertising it to its peers.
* All routers are configured to propagate community attributes.
* R3 is configured with a routing policy that rejects routes with the community attribute 1:1.
In this case, which of the following is the path for traffic from R3 to 192.168.1.0/24?
Answer: B
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Understanding the BGP Network Topology in the Question:
* BGP Peering & Route Distribution
* Each router forms EBGP peer relationships with directly connected neighbors.
* R1 and R4 import the static route 192.168.1.0/24 into BGP and advertise it to their peers.
* Community attributes are attached to routes to influence routing policies.
* Effect of Community Attribute 1:1
* R1 marks 192.168.1.0/24 with community 1:1 before advertising it.
* R3 has a policy that rejects any routes with community attribute 1:1.
* Since R1's advertisement contains 1:1, R3 will not accept 192.168.1.0/24 from R2.
Route Selection and Traffic Flow Analysis:
* R1 advertises 192.168.1.0/24 with community 1:1 to R2.
* R3 rejects this route from R2 because of the configured routing policy.
* R4 also advertises 192.168.1.0/24 to its EBGP neighbors without community 1:1.
* R5 learns the route from R4 and advertises it to R3.
* Since R5's advertisement does not include community 1:1, R3 accepts the route from R5.
* Thus, the best available path for R3 to reach 192.168.1.0/24 is R3 # R5 # R1.
# Correct Path: R3 # R5 # R1
Checking Each Option:
# Option A: R3 # R2 # R4 (Incorrect)
* R3 does not learn the route from R2 because it rejects community 1:1.
* Since R1 added 1:1, and R2 propagated the same community, R3 will not accept this path.
# Option B: R3 does not have a route to 192.168.1.0/24 (Incorrect)
* R3 does have a route, but it learns it from R5 instead of R2.
# Option C: R3 # R2 # R1 (Incorrect)
* R1 marked the route with 1:1, and R2 advertised it with the same community.
* Since R3 rejects 1:1 routes, it will not use this path.
# Option D: R3 # R5 # R1 (Correct)
* R5 learns the route from R4, which does not have community 1:1, and advertises it to R3.
* R3 accepts this route and forwards traffic to R5, which sends it to R1.
Final Conclusion:
# D. The correct path for traffic from R3 to 192.168.1.0/24 is R3 # R5 # R1.
Thus, the correct answer is: D.

NEW QUESTION # 19
As shown in the figure, an engineer uses 4 routers to test branch network interoperability. Among them, R1, R2, and R3 in branch 1 deploy OSPF to implement network interoperability. R2, R3, and R4 in branch 2 deploy IS-S to implement network interoperability. Now the engineer wants to implement R1 to access the loopback interface address of R4. Which of the following operations can meet this requirement?
Answer: B
NEW QUESTION # 20
A network device has established an OSPF neighbor relationship with another device. The figure shows the configuration of GE0/0/0 on the network device.
Which of the following commands would NOT affect the OSPF neighbor status of the interface?
Answer: A
Explanation:
Comprehensive and Detailed In-Depth Explanation:
To determine the correct answer, we need to analyze how each command impacts OSPF neighbor relationships.
1. Understanding OSPF Neighbor Formation
OSPF routers form neighbor relationships when they meet the following conditions:
* They are in the same subnet (IP addresses and subnet masks must match).
* They are in the same OSPF area.
* They use the same network type (e.g., Broadcast, Point-to-Point).
* Authentication (if configured) must match.
* Hello and Dead timers must match.
2. Analyzing Each Answer Option
# A. " undo ip address 10.0.12.2 24 " # Affects OSPF Neighbor Status
* Removing the IP address will prevent the interface from sending and receiving OSPF Hello packets.
* Without an IP address, OSPF cannot establish neighbor relationships.
* Effect: Breaks OSPF neighbor status.
# B. " undo description " # Does NOT Affect OSPF Neighbor Status
* The interface description is just a label for administrators and has no impact on OSPF functionality.
* It does not affect neighbor relationships, routing, or communication.
* Effect: No impact on OSPF neighbors.
# C. " undo ospf cost " # Affects OSPF Neighbor Status Indirectly
* OSPF cost determines the path selection but does NOT break the neighbor relationship.
* However, if the cost change leads to routing table recalculations, it might cause temporary convergence issues.
* Effect: Does not directly break neighbor status, but affects route selection.
# D. " undo ospf dr-priority " # Affects OSPF Neighbor Status (Possibly Causes DR Re-Election)
* OSPF DR/BDR election uses priority values.
* If changed, a new election might occur, leading to a temporary loss of neighbor relationships.
* Effect: Might cause OSPF neighbor reset (temporary impact on adjacency).
