You work for a large company that has just acquired another smaller company. You have been asked to lead a group of SAN experts from both companies to design the integration plan that will be used to interconnect the SANs and migrate the data from the newly acquired company to the main storage arrays.
The first thing that the team discovers is that the two SANs have the same domain IDs.
As the SAN team lead, what would you advise your team to do so that you can interconnect the two SANs while minimizing disruption?
- A. Change the domain IDs on both SANs so that they are both unique and then connect ISLs between the SANs.
- B. The two SANs cannot be merged without disruption.
- C. Use IVR NAT with a transit VSAN between the SANs.
- D. Use FCIP with Write Acceleration and IVR version 1 with a transit VSAN to expedite the data transfer between the two SANs.

IVR Network Address Translation (NAT) can be enabled to allow non-unique domain IDs; however, without NAT, IVR requires unique domain IDs for all switches in the fabric. IVR NAT simplifies the deployment of IVR in an existing fabric where non-unique domain IDs might be present.

- A. Add a default route in each branch toward the data center on the West Coast.
- B. Build an overlay MPLS network with Layer 3 VPN.
- C. Use Optimized Edge Routing at the data center.
- D. Add a redundant data center on the East Coast to serve some of the traffic there.
- E. Add an aggregation layer router in each geographical zone.

You are implementing a one-to-many multicast solution for a large service provider network. Which technology offers optimal routing of multicast traffic?
- A. Anycast RP
- B. MSDP
- C. PIM sparse mode
- D. PM SSM
- E. Bidirectional PIM
Answer: D
Explanation:
Explanation/Reference:
Explanation:
Before you begin the PIM configuration process, decide which PIM mode to use.This is based on the applications you intend to support on your network. Use the following guidelines:
In general, if the application is one-to-many or many-to-many innature, then PIM-SM can be used
successfully.
For optimal one-to-many application performance, SSM is appropriate but requires IGMP version 3
support.

Service provider XYZ plans to provide dedicated Internet access and MPLS L3VPN services to
business customers. XYZ has these design specifications:
-MP-BGP running on the core MPLS P routers with external Internet routes.
-The core network will include 16 Point of Presence IP POPs throughout the Asia-Pacific region.
-An additional nine non-P routers will use EBGP peering with multiple providers for Internet
traffic. -An additional 50 PE routers will provide end customers with dedicated Internet access and L3VPN services throughout the Asia-Pacific region.
In what two ways can the MP-BGP be removed from the MPLS P core routers and still provide dedicated Internet access and MPLS L3VPN services? (Choose two.)
- A. It is not possible to disable BGP from the MPLS core P routers without impacting the dedicated Internet access and MPLS L3VPN services.
- B. Enable all EBGP routers as route reflector servers and MPLS PE routers as their clients.
- C. Enable separate BGP control plane routers using a route reflector server concept that will be fully meshed with peer route reflector servers and have clients as MPLS PE routers and EBGP peering routers.

OSPF timers have not been modified on any router.
Which network will converge faster, and why, if the link between 10.1.1.0/24 and router P4S-RA fails?
- A. They will converge at approximately the same time, because all routers have an equal cost alternate path.
- B. Network 1 will converge faster, because there are fewer flooding hops through the network.
