Question No: 9

Which three options are benefits of using VRFs within an enterprise network? (Choose three.)

A. simplifies configuration and troubleshooting

B. enables partitioning of network resources

C. enhances security between user groups

D. provides additional redundancy at Layer 3

E. allows for routing and forwarding separation

F. improves routing protocol convergence

Answer: B,C,E

Question No: 10

Which statement about Fibre Channel communications is correct?

A. N_Port to N_Port connections use logical node connection points.

B. Flow control is only provided by QoS.

C. It must be implemented in an arbitrated loop.

D. Communication methods are similar to those of an Ethernet bus.

Answer: A

Explanation:

Fibre Channel supports a logical node connection point between node ports (N_ports). This is similar to TCP and UDP sockets.

Question No: 11

A company's virtualization team wants to transfer control of network switching and policy management for VMware virtual servers to the networking team. What Cisco network virtualization solution should be implemented?

A. Unified Computing System

B. Nexus distributed virtual switch

C. virtual network agent

D. Nexus unified fabric switch

Answer: B

Explanation: Nexus 1000v

Question No: 12

Support of vPC on the Cisco Nexus 5000 access switch enables various new design options for the data center Access layer, including which of the following?

A. The vPC peer link is not required for Access layer control traffic, and can instead be used to span VLANs across the vPC access switches

B. A single switch can associate per-interface with more than one vPC domain

C. vPC can be used on both sides of the MEC, allowing a unique 16-link EtherChannel to be built between the access and aggregation switches

D. Allows an EtherChannel between a server and a access switch while still maintaining the level of availability that is associated with dual-homing a server to two different access switches

Answer: C

Question No: 13

Which of these is true of IP addressing with regard to VPN termination?

A. addressing designs need to allow for summarization

B. termination devices need routable addresses inside the VPN

C. IGP routing protocols will update their routing tables over an IPsec VPN

D. designs should not include overlapping address spaces between sites, since NAT is not supported

Answer: D

Question No: 14

Which NAC design model matches the following definitions?

NAS is deployed centrally in the core or distribution layer. Users are multiple hops away from the Cisco NAS.

After authentication and posture assessment, the client traffic no longer passes through the Cisco NAS.

PBR is needed to direct the user traffic appropriately

A. Layer 3 in-band virtual gateway

B. Layer 3 out-of-band with addressing

C. Layer 2 in-band virtual gateway

D. Layer 2 out-of-band virtual gateway

Answer: B

Explanation:

https://www.cisco.com/c/en/us/products/collateral/security/nac-appliance-clean-access/product_data_sheet0900aecd802da1b5.html

Passing traffic mode

u2022 Virtual gateway (bridged mode)

u2022 Real IP gateway (routed mode)

Client access mode

u2022 Layer 2 (client is adjacent to the Cisco NAC Server)

u2022 Layer 3 (client is multiple hops from the Cisco NAC Server)

Traffic flow model

u2022 In-band (Cisco NAC Server is always in-line with user traffic)

u2022 Out-of-band (Cisco NAC Server is in-line only during authentication, posture assessment, and remediation)

Question No: 15

What is the primary benefit of implementing Virtual Device Contexts on Nexus hardware In a multi- tenant environment?

A. resource isolation

B. software partitioning

C. resource allocation

D. granular monitoring

Answer: A

Question No: 16

What SAN technology can accomplish fabric infrastructure implementation using multiple fabrics?

A. VSAN

B. IVR

C. SCSI

D. NAS

Answer: A

Question No: 17

Which multicast implementation strategy provides load sharing and redundancy by configuring intradomain RPs as MSDP peers?

A. anycast RP

B. auto-RP

C. bootstrap router

D. static RP

Answer: A

Explanation: https://www.cisco.com/c/en/us/td/docs/ios/solutions_docs/ip_multicast/White_papers/anyca st.html#wp1029118

"Anycast RP is a useful application of MSDP. Originally developed for interdomain multicast applications, MSDP used for Anycast RP is an intradomain feature that provides redundancy and load-sharing

capabilities. Enterprise customers typically use Anycast RP for configuring a Protocol Independent Multicast sparse mode (PIM-SM) network to meet fault tolerance requirements within a single multicast domain."

Question No: 18

Which two design recommendations are most appropriate when OSPF is the data center core routing protocol? (Choose two.)

A. Never use passive interfaces.

B. Use NSSA areas from the core down.

C. Use totally stub areas to stop type 3 LSAs.

D. Use the lowest Ethernet interface IP address as the router ID.

E. Manipulate the reference bandwidth.

Answer: B,E
