  1. an appliance port

  2. vPC

  3. a port channel

  4. a unified storage port

Correct Answer: C

Question No.22

Which technology provides the ability to use all links in a LAN topology by providing an active- active path to the upstream switch?

  1. STP

  2. vPC

  3. PVST

  4. RSTP

Correct Answer: B

Question No.23

Which two platforms support the FCoE protocol? (Choose two)

  1. Cisco Nexus 2332TQ Series

  2. Cisco MDS 9148S Series

  3. Cisco Nexus 7010 Series

  4. Cisco MDS 9222i Series

  5. Cisco Nexus 2248TP Series

Question No.24

What are two benefits of a service insertion that is mediated through the Cisco APIC instead of the classical Ethernet model? (Choose two.)

  1. provides Layer 5 service insertion capability

  2. provides Layer 7 service insertion capability

  3. provides policies that can manage the network and service appliances

  4. can automate the service insertion

  5. provides built-in services, such as Cisco ACE Web Application Firewall and ADC

Correct Answer: BC

Question No.25

Which option can be used to provide a nonproprietary method of load balancing and redundancy between the access and aggregation layers in the data canter?

  1. vPC

  2. PAgP

  3. LACP

  4. host vPC

Correct Answer: C

Question No.26

You have a Cisco Nexus 5500 Series switch. What is the default load-balancing hash mechanism for traffic on FCoE port channels?

  1. the source MAC address

  2. the source IP address and the destination IP address

  3. the source MAC address and the destination MAC address

  4. the source TCP or UDP port and the destination TCP or UDP port

Correct Answer: B

Explanation:

On Nexus 5500 the default load balancing mechanism on the LACP port- channel for FCoE traffic is quot;source-destinationquot;. In this default state, all the FCoE traffic takes the same link in the port- channel when the Nexus 5500 forwards frames over FCoE VE ports. In order to enable all links to be used in the port-channel for FCoE traffic, enter the port-channel load-balance ethernet source- dest-port command to configure Nexus 5500 quot;port-channel load balancingquot; to quot;source-dest-portquot;. With this configuration quot;source- destination-oxidquot; load balancing is used for FCoE traffic.

Question No.27

Service graphs are used to define which option on the Cisco ACI platform?

  1. a function that a contract must use to get to another contract

  2. a function that an EPG must use to get to another EPG

  3. the contract between two EPGs

  4. the Cisco APIC definitions of the contracts in REST API

Correct Answer: B

Question No.28

Which statement accurately describes VSAN-based QoS when the same flow is present in two class maps that are associated to a policy map?

  1. The highest QoS value is used.

  2. The lowest QoS value is used.

  3. The QoS value of the class map that is attached first takes effect.

  4. The QoS value of the class map that is attached last takes effect.

Correct Answer: C
