350-501 practice questions 341–350

1. Question 341 · 377 in bank

   

   Refer to the exhibit. Based on the show command output, which result is true after BGP session is established?

   • AThe IOS XR router advertises and accepts all routes to and from eBGP neighbor 192.168.2.2.
   • BThe IOS XR router advertises all routes to the neighbor 192.168.2.2, but it does not accept any routes from 192.168.2.2.
   • CNo routes are accepted from the neighbor 192.168.2.2, nor are any routes advertised to it.
   • DThe IOS XR router does not advertises any routes to the neighbor 192.168.2.2, but it accepts any routes from 192.168.2.2.

   Show answer

   Answer: C

   Explanation

   C is correct but the reason why the router will not advertise nor receive the prefix is because of the default EBGP policy in iOS XR which will block all incoming and outgoing prefixes.

2. Question 342 · 377 in bank

   

   Refer to the exhibit Which effect of this configuration is true?

   • AThe two routers fail to form a neighbor relationship because they have different IS-IS area types.
   • BThe two routers successfully form a neighbor relationship.
   • CThe two routers fail to form a neighbor relationship because the authentication configuration is missing.
   • DThe two routers fail to form a neighbor relationship because their system IDs are different.

   Show answer

   Answer: A

   Explanation

   Correct Answer is A. The two routers fail to form a neighbor relationship because they have different IS-IS area types. Router Type L1 with L1/2 successfully form Adjacency if Area Id Matches, else no Adjacency

3. Question 343 · 377 in bank

   

   Refer to the exhibit. In which way does router R1 operate differently than router R2?

   • AR1 sends LSA types 5 and 7, while R2 sends type 1, 2, and 7 LSAs.
   • BR1 sends LSA type 2 only, while R2 sends type 1 and type 7 LSAs.
   • CR1 sends LSA type 2 only and R2 sends LSA type 1 only.
   • DR1 sends LSA types 1 and 2, while R2 sends type 1,2, and 7 LSAs.

   Show answer

   Answer: D

   Explanation

   Couldn't be C as R1 would generate LSA T1 & LSA T2. While you're correct that NSSA generate a T7 LSA, they also generate T1 Router & T2 Network LSAs. LSA T1 describe the router (that generates them) interface and also carries information about its adjacent neighbors in the same area. LSA T2 are generated by a DR on a segment (unless the network point-to-point has been configured) and are default on ethernet interfaces. This LSA lists routers that make up the segment, including the DR itself. Therefor D is the correct answer!

   Refer to the exhibit. Which purpose of implementing NSF with this configuration is true?

   • AThe router uses NSF to handle RP switchover while allowing neighbor relationships to remain up.
   • BThe router uses NSF to reduce neighbor-relationship downtime during RP switchover.
   • CThe router uses NSF to load balance traffic on a routed EtherChannel.
   • DThe router uses NSF to load balance traffic between two links, with the primary link alternating every 90 seconds.

7. Question 347 · 377 in bank

   

   Refer to the exhibit. An engineer with an employee ID: 1234:56:789 started to configure two routers for OSPF for a client. They are advertising their loopback addresses. Which additional configuration must the engineer perform so that the GigabitEthernet 1/1 link is preferred and the GigabitEthernet 2/1 link is a backup?

   • Arouter1(config)# router ospf 1 Router1 (config-router)# auto-cost reference-bandwidth 1000 router2(config)# router ospf 1 router2(config-router)# auto-cost reference-bandwidth 1000
   • Brouter1(config)# router ospf 1 router1(config-router)# auto-cost reference-bandwidth 100 router2(config)# router ospf 1 router2(config-router)# auto-cost reference-bandwidth 100

8. Question 348 · 377 in bank

   Company A must increase throughput between two non-IEEE 802.3ad switches located in the access and distribution layers. A network engineer must create a link group with the same speed and duplex. The STP protocol must not block any of the group ports. Which action completes the implementation?

   • ABundle the physical interfaces with mode lacp configured on each of them.
   • BEnable Port Aggregation Protocol with mode auto under the logical group interface.
   • CConfigure a group logical interface with mode active enabled.
   • DGroup Ethernet interfaces with mode desirable under the physical interfaces.

9. Question 349 · 377 in bank

   

   Refer to the exhibit. During the last maintenance window, the network engineering team performed multiple software upgrades and enabled OSPFv3 for future use. However, when the network came up, the connection between HQ and the remote branch failed. A network engineer determined that routers R1 and R2 failed to establish an OSPFv2 adjacency. R1 was preconfigured with the point-to-point OSPF network type, and R2 as broadcast. The engineer confirmed that all connected interfaces are up, and the routers can reach one another via ICMP. Which action must the engineer take to resolve the issue?

   • AChange the hello and dead intervals on the interfaces on R1 and R2 to the same values respectively.
   • BConfigure R1 and R2 with the same OSPFv3 router ID.
   • CSet the same network statement under the OSPFv2 configuration on R1 and R2.
   • DSet the R1 OSPFv2 process ID to match the R2 OSPFv2 process ID.

    • Bwhen the route’s first hop has a different AS number
    • Cwhen the route’s next hop is unreachable
