Question 8

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) Use FCIP with Write Acceleration and IVR version 1 with a transit VSAN to expedite the data transfer between the two SANs.
B) Change the domain IDs on both SANs so that they are both unique and then connect ISLs between the SANs.
C) Use IVR NAT with a transit VSAN between the SANs.
D) The two SANs cannot be merged without disruption.

Accepted Answer

Using IVR NAT with a transit VSAN allows for the interconnection of SANs with overlapping domain IDs by translating the domain IDs, thus minimizing disruption.

Question 9

You are designing a large Frame Relay WAN for a customer. The routing protocol is OSPF. What is the effect on the routing table if the WAN interfaces are configured as point-to-multipoint?
A) Only a route for the DR will be present in the routing table.
B) Configuring point-to-multipoint has no effect on the routing table. The route that is configured with the area command will be seen in the routing table.
C) Multipoint interfaces dynamically add the network of the connected interface.
D) Multipoint interfaces dynamically add a /32 route for each neighbor in the WAN.

Accepted Answer

Point-to-multipoint interfaces in OSPF dynamically add a /32 route for each neighbor in the WAN, which reflects the individual connections to each neighbor.

Question 10

In an OSPF network, users in a particular OSPF non-backbone area are complaining about slow access speeds to a shared corporate resource in another OSPF area. Traceroutes show that the users are taking a suboptimal default route to the destinations. Which solution will improve access speed?
A) Make the area totally stubby so that the default can be followed along the best path.
B) Create a virtual link between the areas so that traffic can shortcut directly between them.
C) Implement policy routing to channel the traffic in the optimal direction.
D) Leak specific summaries on the ABRs for the remote subnets in addition to the default.

Accepted Answer

Leaking specific summaries on the ABRs allows routers in the non-backbone area to have more specific routing information, enabling them to choose a more optimal path rather than relying on a suboptimal default route.

Question 11

A Mobile Service Provider would like to design and deploy an Ethernet service which has similar physical link failover/failback characteristics on the active/backup links as the APS/MSP SONET properties. Which Layer 2 services should be considered to address this design feature?
A) Port-Channel
B) MLPPP
C) Flex Link
D) Ethernet Pseudowires

Accepted Answer

Flex Link is a Layer 2 feature that provides link redundancy and fast failover similar to APS/MSP in SONET networks, allowing for quick switching between active and backup links.

Question 13

A Tier-3 Service Provider is evolving into a Tier-2 Service Provider due to the amount of Enterprise business it is receiving. The network engineers are re-evaluating their IP/MPLS design considerations in order to support duplicate/overlapping IP addressing from their Enterprise customers within each Layer 3 VPN. Which of the following would need to be reviewed to ensure stability in their network?
A) Assigning unique Route Target ID's
B) Assigning unique Route Distinguishers
C) Assigning unique IP address space for the Enterprise NAT/Firewalls
D) Assigning unique VRF ID's to each Layer 3 VPN

Accepted Answer

Route Distinguishers (RDs) are used in MPLS VPNs to make overlapping IP addresses unique across different VPNs. This is crucial for supporting multiple customers with potentially overlapping IP address spaces.

Question 14

A company is planning to deploy high-availability cluster support for their servers in a collapsed core data center design. Which issue should be a concern with this design?
A) NIC teaming
B) MAC address aging
C) Layer 3 domain sizing
D) Layer 2 domain sizing

Accepted Answer

In a collapsed core design, Layer 2 domain sizing can be a concern because it can lead to larger broadcast domains, which can affect network performance and stability.

Question 15

You are designing an Out of Band Cisco Network Admission Control, Layer 3 Real-IP Gateway deployment for a customer. Which VLAN must be trunked back to the Clean Access Server from the access switch?
A) untrusted VLAN
B) user VLAN

A) stateful NAT-PT
B) NAT-PT
C) stateless NAT64
D) stateful NAT64

Accepted Answer

Stateful NAT64 is designed to translate IPv6 addresses to IPv4 addresses and vice versa, supporting multiple IPv6 devices to share a single IPv4 address, which is suitable for flow-based translations.

A) N-Port Identifier Virtualization
B) Inter-Virtual Storage Area Network Routing
C) Zoning
D) Fabric Port Trunking
E) Node Port Virtualization
F) Expansion Port Trunking

Accepted Answer

N-Port Identifier Virtualization (NPIV) allows a single Fibre Channel port to register multiple World Wide Names (WWNs) and therefore multiple Fibre Channel IDs, enabling multiple virtual machines to share a single physical port.
