NEW QUESTION 2
Which statement accurately describes the implementation of FSPF on Cisco MDS 9700 Series switches?

• A. FSPF is enabled on the Fibre Channel switches but must be enabled manually on a per-VSAN basis.
• B. FSPF must be enabled manually on the switch and on each VSAN on the switch.
• C. FSPF is enabled, by default, on the Fibre Channel switches for all VSANs.

Answer: A

NEW QUESTION 3
Which topology is not supported when using vPC?

• A. a single-homed server to a single FEX that is connected to two Cisco Nexus 5500 Series Switches
• B. a dual-homed server to two FEXs, each connected to two Cisco Nexus 5500 Series Switches
• C. a dual-homed server to two FEXs that are connected to one Cisco Nexus 5500 Series Switch
• D. a dual-homed server to a single FEX that is connected to two Cisco Nexus 5500 Series Switches

Answer: C

Explanation: The figure shows unsupported topology where a vPC is between hosts and two FEXs that are connected to one Cisco Nexus 5500 Series device. This topology does not provide a good high availability solution because the server loses the connectivity to the network when the Cisco Nexus 5000 Series device fails.

If you need to connect a multi-homing server to a pair of FEXs when there is only one Cisco Nexus 5000 Series device, you have the option to run active or standby NIC teaming from the server. Reference: http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/mkt_ops_guides/513_n1_1

NEW QUESTION 4
Refer to the exhibit.

This multilayer Cisco Nexus switch had been the active virtual gateway for Group 1 before it became temporarily unavailable. What will happen to GLBP Group 1 when this device becomes available again?

• A. The currently active router remains active.
• B. It depends on the priority value that is configured active on the router.
• C. The Cisco Nexus switch becomes the active virtual gateway after 600 seconds.
• D. It depends on the weighting values that are configured active on the router.

Answer: A

Explanation: GLBP prioritizes gateways to elect an active virtual gateway (AVG). If multiple gateways have the same priority, the gateway with the highest real IP address becomes the AVG. The AVG assigns a virtual MAC address to each member of the GLBP group. Each member is the active virtual forwarder (AVF) for its assigned virtual MAC address, forwarding packets sent to its assigned virtual MAC address.
The AVG also answers Address Resolution Protocol (ARP) requests for the virtual IP address. Load sharing is achieved when the AVG replies to the ARP requests with different virtual MAC addresses. Note: Packets received on a routed port destined for the GLBP virtual IP address terminate on the local router, regardless of whether that router is the active GLBP router or a redundant GLBP router. This termination includes ping and Telnet traffic. Packets received on a Layer 2 (VLAN) interface destined for the GLBP virtual IP address terminate on the active router.

• C. Each vFC interface must be bound to an FC enabled Ethernet or EtherChannel interface or to the MAC address of a remotely connected adapter

NEW QUESTION 11
You enable the HSRP feature on a Cisco Nexus 7000 Series switch. You must ensure that the switch manages packets that are sent to the local vPC MAC address, remote vPC MAC address, and HSRP virtual MAC address. Which command should you run?

• A. Peer-gateway

• D. peer-switch

NEW QUESTION 12
Between which two types of ports does FIP establish Fibre Channel virtual links? (Choose two.)

• A. VE Ports and VE Ports
• B. N Ports and F Ports
• C. VN Ports and VF Ports
• D. VP Ports and VE Ports
• E. VE Ports and VF Ports
• F. E Ports and E Ports

Answer: AC

Explanation: FIP aims to establish virtual FC links between VN_Ports and VF_Ports (ENode to FCF), as well as between pairs of VE_Ports (FCF to FCF), since these are the only legal combinations supported by native Fibre Channel fabrics. Standards-compliant implementations are not required to support both forms of virtual FC links, and Cisco has decided to focus initially on implementing FIP only between ENodes and FCFs. FCF-to-FCF connectivity is considered a strategic direction for end-to-end FCoE deployments, but the short-term urgency is for FCoE adoption between CNAs and the Fibre Channel fabric perimeter, where unified fabric can offer the greatest capital expenditure (CapEx) savings today.

NEW QUESTION 15
Which statement about Cisco FabricPath is true?

• A. It is the best solution for interconnecting multiple data centers.
• B. It optimizes STP throughout the Layer 2 network.
• C. It is a simplified extension of Layer 3 networks across a single data center.
• D. The Cisco FabricPath domain appears as a single STP bridge, where each edge port uses the same MAC address.

Answer: D

Explanation: To have a loop-free topology for the CE/FabricPath hybrid network, the FabricPath network automatically displays as a single bridge to all connected CE devices. The STP domains do not cross into the FabricPath network. If multiple STP domains are defined, BPDUs and topology change notifications (TCNs) are localized to the domain. If a connected STP domain is multihomed to the FabricPath domain, a TCN must be able to reach to all devices in the STP domain through the FabricPath domain. As a result, the TCN is sent to the FabricPath domain through the IS-IS protocol data unit (PDU) by default.

NEW QUESTION 16
Which statement about scalability in Cisco OTV is true?

• A. The control plane avoids flooding by exchanging MAC reachability.
• B. IP-based functionality provides Layer 3 extension over any transport.
• C. Any encapsulation overhead is avoided by using IS-IS.
• D. Unknown unicasts are handled by the authoritative edge devic

Answer: A

Explanation: Cisco calls the underlying concept of OTV traffic forwarding "MAC routing", since it behaves as if you are routing Ethernet frames over the DCI transport. OTV uses a control plane protocol to proactively propagate MAC address reachability before traffic is allowed to pass, which eliminates dependency
on flooding mechanism to either learn MAC addresses or forward unknown unicasts. Reference:
