Exhibit.

You want to verify prefix information being sent from 10.36.1.4.
Which two statements are correct about the output shown in the exhibit? (Choose two.)

Correct Answer:AB
The output shown in the exhibit is the result of the command ??show ip bgp neighbor 10.36.1.4 received-routes??, which displays all received routes (both accepted and rejected) from the specified neighbor.
Option A is correct, because the routes displayed have traversed one or more autonomous systems. This can be seen from the AS_PATH attribute, which shows the sequence of AS numbers that the route has passed through. For example, the route 10.0.0.0/8 has an AS_PATH of 65001 65002, which means that it has traversed AS 65001 and AS 65002 before reaching the local router.
Option B is correct, because the output shows routes that were received prior to the application of any BGP import policies. This can be seen from the fact that some routes have a status code of ??r??, which means that they are rejected by an import policy. The??received-routes?? keyword shows the routes coming from a given neighbor before the inbound policy has been applied. To see the routes after the inbound policy has been applied, the ??routes?? keyword should be used instead.
Option C is incorrect, because the output does not show routes that are active and rejected by an import policy. The status code of ??r?? means that the route is rejected by an import policy, but it does not mean that it is active. The status code of ??>?? means that the route is active and selected as the best path. None of the routes in the output have both ??>?? and ??r?? status codes.
Option D is incorrect, because the routes displayed are not being learned from an IBGP peer. An IBGP peer is a BGP neighbor that belongs to the same AS as the local router. The output shows that the neighbor 10.36.1.4 has a remote AS of 65001, which is different from the local AS of 65002. Therefore, the neighbor is an EBGP peer, not an IBGP peer.

Refer to the exhibit.

Referring to the output shown in the exhibit, which statement is correct?

Correct Answer:B
In OSPF, the state of the neighbor relationship is determined by the exchange of OSPF packets between routers1. The state ??2Way?? as shown in the exhibit indicates that bi-directional communication has been established between the two OSPF routers1. This is the normal state for a neighbor that is not the Designated Router (DR) or Backup Designated Router (BDR) on a broadcast, non-broadcast multi-access (NBMA), or point-to-multipoint network1. These neighbors are often referred to as "DRothers"1. Therefore, option B is correct.

After receiving a BGP route, which two conditions are verified by the receiving router to ensure that the received route is valid? (Choose two)

Correct Answer:BC
✑ B is correct because the loops do not exist is one of the conditions that are verified by the receiving router to ensure that the received BGP route is valid. A loop in BGP means that a route has been advertised by the same AS more than once, which can cause routing instability and inefficiency1. To prevent loops, BGP uses the AS-path attribute, which lists the AS numbers that a route has traversed from the origin to the destination2. The receiving router checks the AS-path attribute of the received route and discards it if it finds its own AS number in the list2. This way, BGP avoids accepting routes that contain loops.
✑ C is correct because the next hop is reachable is one of the conditions that are verified by the receiving router to ensure that the received BGP route is valid. The next hop is the IP address of the next router that is used to forward packets to the destination network3. The receiving router checks the next hop attribute of the received route and verifies that it has a valid route to reach it3. If the next hop is not reachable, the received route is not usable and is rejected by the receiving router3. This way, BGP ensures that only feasible routes are accepted.

You are attempting to configure the initial two aggregated Ethernet interfaces on a router but there are no aggregated Ethernet interfaces available.
In this scenario, which configuration will enable these interfaces on this router?
A)

B)

C)

D)

Correct Answer:C
The correct answer to your question is C. Option C. Here is why:
✑ Option C shows the configuration of the chassis statement, which defines the properties of the router chassis, such as the number of aggregated Ethernet interfaces, the number of FPCs, and the number of PICs1.
✑ To enable aggregated Ethernet interfaces on a router, you need to specify the aggregated-devices statement under the chassis statement and set
the ethernet parameter to the desired number of interfaces2. For example, to enable two aggregated Ethernet interfaces, you can use the following configuration:
chassis { aggregated-devices { ethernet { device-count 2; } } }
✑ Option C shows this configuration with the device-count set to 2, which will enable two aggregated Ethernet interfaces on the router. The other options do not show this configuration and will not enable any aggregated Ethernet interfaces on the router.
✑ Therefore, option C is the correct answer to your question.

You are an operator for a network running 1S-IS. Two routers are failing to form an adjacency. What are two reasons for this problem? (Choose two.)

Correct Answer:BD
The two reasons for the failure to form an adjacency in a network running IS- IS could be:
* B. There is no configured ISO address on any IS-IS interface. IS-IS requires each router interface to have an ISO address configured. Without this address, the routers cannot form an adjacency1.
* D. The family iso configuration is missing from the adjacency interface. The ??family iso?? configuration is essential for IS-IS to function correctly. If this configuration is missing from the adjacency interface, it could prevent the formation of an adjacency1.
These explanations are based on the Enterprise Routing and Switching Specialist (JNCIS- ENT) documents and learning resources available at Juniper Networks23.

Exhibit

You are a network operator troubleshooting BGP connectivity.
Which two statements are correct about the output shown in the exhibit? (Choose two.)

Correct Answer:BC
Option B suggests that the BGP session is not established. This is correct because in the output, the state of the BGP session is shown as ??Idle??. In BGP, an ??Idle?? state means that the BGP session is not currently established1.
Option C suggests that R1 is configured for AS 65400. This is also correct because in the output, it??s shown that the local AS number is 654001. The local AS number represents the Autonomous System (AS) number of the router on which you??re checking the BGP session1.
