Refer to the exhibit Routers R1 and R2 are connected via a senal link and use the IS-IS routing protocol for route exchange After a configuration change on R2. IS-IS connectivity is interrupted A network engineer confirmed that the interfaces are in the UP state and connectivity exists between the two routers. Which two actions must the engineer perform to resolve the problem? (Choose two.)

• A.Disable padding for hello packets under the serial interface on R2 DUMPS
• B.Change the hello interface timer to 10 seconds on R1.
• C.Change the MTU to 1500 bytes on R2.
• D.Enable hello packet padding globally on R1.
• E.Change R2 to an IS-IS Level 1 router.

Refer to the exhibit. The operations team is implementing a route-map policy. Traffic from source
192.168.30.1 must reach the customer network 192.168.1.1 via the secondary link R4-R6-R5. All other traffic from the data center to the customer network must prefer the primary link R4-R3-R2.
Which action must be taken to meet the requirement for prefix 192.168.1.1/32?

• A.Apply route-map PrefixBlock in on R6 with R5 BGP peering.
• B.Apply route-map Low-LP in on R4 with R3 BGP peering
• C.Apply route-map PrefixBlock out on R3 with R4 BGP peering.
• D.Apply route-map High-LP on R6 with R4 BGP peering.

• B.It guarantees a loop-free path for all interfaces in the OSPF super backbone
• C.It applies only on the instance and makes all the interfaces inherit the configuration

Refer to the exhibit. Company A is connected to multiple upstream ISPs, with ISP_A serving as the primary upstream ISP. The company A subnet 172.43.232.0 should be announced to the secondary ISP_B only when the FTP server with IP address 10.10.1.1 is not accessible via the primary ISP. Which configuration must be applied on R1?

• A.neighbor 10.182.213.3 advertise-map Advertise-route non-exist-map Non-RIB
• B.neighbor 10.182.213.3 prefix-map Non-RIB Condition-map Advertise-route
• C.neighbor 10.182.213.3 route-map Advertise-route Condition-map Non-RIB
• D.neighbor 10.182.213.2 Condition-map Non-RIB prefix-map Advertise-route
