NEW QUESTION 33
Drag and drop the characteristics from the left onto the correct telemetry mode on the right.
Answer:
Explanation:
Explanation
In a dial-in mode, the destination initiates a session to the router and subscribes to data to be streamed. Dialin mode is supported over gRPC in only 64-bit platforms In a dial-out mode, the router initiates a session to the destinations based on the subscription. All 64-bit IOS XR platforms (except for NCS 6000 series routers) support gRPC and TCP protocols. All 32-bit IOS XR platforms support only TCP.
NEW QUESTION 34

Which design consideration should be observed when EIGRP is configured on Data Center switches?
- A. Configure multiple EIGRP autonomous systems to segment Data Center services and applications.
- B. Prevent unnecessary EIGRP neighborships from forming across switch virtual interfaces.
- C. Lower EIGRP hello and hold timers to their minimum settings to ensure rapid route reconvergence.

Answer: D
NEW QUESTION 43
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. Assign the same IS-IS NET value for each campus, and configure internal campus routers with Level 1/ Level 2 routing.
- B. 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.
- C. Utilize different MTU values for each campus network segment. Level 2 backbone routers must utilize a larger MTU size of 9216.
- D. Designate two IS-IS routers from each campus to act as Level 1/Level 2 backbone routers at the edge of each campus network.
- E. Assign a unique IS-IS NET value for each campus, and configure internal campus routers with Level 1 routing.
Answer: D,E

- C. Run an eBGP session within different VRFs for each ISP.
- D. Apply route filtering such that the client advertises only routes originated from its own AS.
Answer: B
