NEW QUESTION # 62
The Cisco UCS environment must be connected to an existing SAN network that consists of several Cisco MDS 9000 Series Switches added to increase storage density. The solution must not exhaust the SAN network from the list of available domain IDs after connecting. Most of the SAN traffic must be mapped from the Cisco UCS blades to a specific group of the fabric interconnect ports. Which configuration must be deployed to meet these requirements?
- A. Dynamic Pinning and UCS Fabric Interconnect in Fibre Channel Switching Mode
- B. Static Pinning and UCS Fabric Interconnect in Fibre Channel End Host Mode
- C. Dynamic Pinning and UCS Fabric Interconnect in Fibre Channel End Host Mode
- D. Static Pinning and UCS Fabric Interconnect in Fibre Channel Switching Mode
Answer: B
Explanation:
Fibre Channel End Host Mode on the UCS Fabric Interconnects prevents each FI from consuming its own SAN domain ID, preserving your limited domain pool on the MDS fabric.
Static Pinning lets you bind each server blade's vHBA to a specific FI FC uplink port (or port group), ensuring that the majority of traffic from UCS blades egresses exactly where you intend it, without dynamic load-balancing changing paths.
NEW QUESTION # 63
Refer to the exhibit.
An engineer must assign multiple Fibre Channel IDs to a single port channel. Which two features must be enabled this goal? (Choose two.)
- A. Smart Zoning feature on the Cisco UCS Fabric Interconnects
- B. SAN Pin Groups on the Cisco UCS Fabric Interconnects.
- C. NPIV feature on the Cisco MDS Series
- D. NPV feature on the Cisco MDS Series.

NEW QUESTION # 64
Refer to the exhibit. Two Cisco Nexus 9000 Series Switches exchange OSPF routing information with R1. Which action accomplishes this goal?
- A. Add peer-gateway under VPC domain.
- B. Add layer3 peer-router under VPC interface link.
- C. Add peer-gateway under VPC interface link.
- D. Add layer3 peer-router under VPC domain.
Answer: D
Explanation:
Configuring layer3 peer-router at the vPC-domain level makes the two Nexus switches present themselves as a single OSPF neighbor to R1. This setting synchronizes ARP/adjacency state across the peer pair and allows a routed vPC EtherChannel (Po10) to form a proper OSPF adjacency without split-brain issues.
NEW QUESTION # 65
Refer to the exhibit. A Cisco engineer is configuring a PBR in a Cisco ACI data center scenario and plans to insert a transparent firewall. The APIC release is 4.1. the Cisco ACI fabric is configured to be the gateway for the servers and for the PBR node, and the Layer 4/ Layer 7 devices are deployed as Layer 1/ Layer 2 mode in the physical domain. Layer 1/Layer 2 PBR node interfaces arc also configured to be in a bridge domain and not in an L30ut. What is required for the consumer and provider connectors of the Layer 1/Layer 2 device for this scenario to work?
- A. Active/active symmetric PBR is requited.
- B. They must be in different BDs.
- C. PBR is used with Multi-Pod.
- D. IP-SLA Tracking is active.
Answer: B
NEW QUESTION # 66
Refer to the exhibit.
Refer to the exhibit. A 4x10G Fibre Channel has been configured between SW1 and SW2 to carry backup traffic sourced to and from the SAN.

- A. Configure exchange-based load-balancing.
- B. Configure flow-based load-balancing.
- C. Configure src-dst-ip-based load-balancing.
- D. Configure dst-mac-based load-balancing.
Answer: A

- C. redundancy for the management plane only
- D. redundancy via a single fabric interconnect
Answer: B
NEW QUESTION # 71
Refer to the exhibit. A company plans to implement high availability between the iSCSI host and the Fibre Channel target. Which solution must the company implement to recover from a failure of a host NIC, MDS IP storage port, or Fibre Channel target port?
- A. Configure FCoE between the host NICs and MDS ports
- B. Set up IP storage ports to export the two Fibre Channel target ports
- C. Map the Fibre Channel target ports to one IP storage port
- D. Implement HSRPofi thf MDS IP storage ports
Answer: B
Explanation:
Each IPS ports is exporting the same two Fibre Channel target ports of the storage but as different iSCSI target names if you use dynamic iSCSI targets). So the two IPS ports are exporting a total of four iSCSI target devices. These four iSCSI targets map the same two ports of the Fibre Channel target.

Refer to the exhibit. What must be the default gateway of the servers in EPG Web?
- A. subnet address of L3Out
- B. subnet address of BD1
- C. subnet address of BD2
- D. NAT appliance
Answer: D
Explanation:
Because of the NAT, the server subnet and and BD2 subnet are different, so the servers cannot use BD2 subnet gateway. Therefore only the NAT device knows the local gateway for the servers.
