Refer to the exhibit. When YDK is used to interact with Cisco routers, what is the purpose of passing intf_f into the crud_service.read() method?

A. The Interfaces() class acts as a NETCONF filter, which limits the data returned to that of the openconfig:interfaces YANG model. B. It provides the data types of the openconfig:interfaces model to the router for dynamic configuration of the interfaces. C. It locks the interfaces from modification by other active NETCONF sessions. D. It passes default values into… Read More »

Router R1 is configured to advertise outgoing SA messages to routers R2 and R3, but to receive incoming SA messages only from R2. Which additional configuration must an engineer apply to router R1 so it filters all MSDP SA messages from Domain-C?

A. R1# ip msdp sa-filter in 192.168.3.1 B. R3# ip msdp sa-filter out 192.168.3.1 C. R3# ip msdp password peer 192.168.1.1 D. R1# ip msdp password peer 192.168.3.1 Answer: Option A.

A network engineer applied configuration on R1 to summarize all ISIS routes, but R2 is still receiving specific routes from R1. The engineer has confirmed that both routers are configured with the correct summarization configuration, but R1 is not sending the correct summary routes. Which configuration must be applied to router R1 to summarize routes within Level 1?

A network engineer must segregate three interconnected campus networks using IS-IS routing. A two-layer hierarchy must be used to support large routing domains and to avoid more specific routes from each campus network being advertised to other campus network routers automatically. Which two actions does the engineer take to accomplish this segregation? (Choose two.)

A. Designate two IS-IS routers as BDR routers at the edge of each campus, and configure one BDR for all Level 1 routers and one BDR for all Level 2 routers. B. Designate two IS-IS routers from each campus to act as Level 1/Level 2 backbone routers at the edge of each campus network. C. Assign the same… Read More »
