NEW QUESTION # 195
A company wants to switch from static routing to a dynamic routing protocol to ease the administrative and operational overhead. The network topology is hub and spoke, and the branches use DMVPN back to the hub using two 100 Mbps internet connections.

Also, the branch routers have limited memory and CPU resources.
Which routing protocol and design solution must the company choose?
- A. iBGP with the hub routers set up as route reflectors and branches set up as clients
- B. EIGRP with branch routers as stub routers using ECMP
- C. ISIS with the hub and spoke routers configured in two different areas
- D. OSPF deployed in area 0 with branch routers connecting from area 1
Answer: B

NEW QUESTION # 197
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.) 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.
- A. Utilize different MTU values for each campus network segment. Level 2 backbone routers must utilize a larger MTU size of 9216.
- B. Assign the same IS-IS NET value for each campus, and configure internal campus routers with Level 1/ Level 2 routing.
- C. Designate two IS-IS routers from each campus to act as Level 1/Level 2 backbone routers at the edge of each campus network.

NEW QUESTION # 200
Company A recently acquired another company. Users of the newly acquired company must be able to access a server that exists on Company A's network, both companies use overlapping IP address ranges.
Which action conserves IP address space and provides access to the server?
- A. Re-IP overlapping address space in the acquired company
- B. Use a single IP address to create overload NAT
- C. Use a single IP address to create a static NAT entry
- D. Build one-to-one NAT translation for every user that needs access
Answer: C
Explanation:
You wouldn't create a NAT to convert every single user from the newly acquired company into one IP address in the other existing company. You would create a static NAT for traffic destined to the server at the network boundary between the 2 companies. Traffic destined to the server from the newly acquired company would be NAT'd to the server IP in Company A.
