Question #11
You have a Cisco Nexus 5500 Series switch. What is the default load-balancing hash mechanism for traffic on FCoE port channels?
  1. A
    the source MAC address
  2. B
    the source IP address and the destination IP address
  3. C
    the source MAC address and the destination MAC address
  4. D
    the source TCP or UDP port and the destination TCP or UDP port

Correct Answer:
B
On Nexus 5500 the default load balancing mechanism on the LACP portchannel for FCoE traffic is "source-destination". 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 "port-channel load balancing" to
"source-dest-port". With this configuration "sourcedestination-oxid" load balancing is used for FCoE traffic.

Question #12
Which two characteristics are associated with the access layer of a Data Center Unified Fabric network? (Choose two.)
  1. A
    voice, data, and wireless convergence
  2. B
    no packet manipulation
  3. C
    QoS-policing
  4. D
    routing manipulation and filtering
  5. E
    QoS – classification and queueing

Correct Answer:
AE

Question #13
Which option accurately describes the OSPF Graceful Restart feature in Cisco NX-OS?
  1. A
    keeps the plane state active during an OSPF process restart
  2. B
    shuts down the OSPF process gracefully to replace the router
  3. C
    prevents the OSPF process from restarting when the process crashes
  4. D
    allows a router to remain in the data forwarding path during an OSPF process restart

Correct Answer:
D
A graceful restart, or nonstop forwarding (NSF), allows OSPFv2 to remain in the data forwarding path through a process restart. When OSPFv2 needs to perform a graceful restart, it sends a link-local opaque (type 9) LSA, called a grace LSA.
