  With the Nexus 5x00 switch, FCoE functionality is a licensed feature. After the license is installed, FCoE configuration can be completed. Reference: http://www.ciscopress.com/articles/article.asp?p=2030048andseqNum=4

• Question 104:

  Drag the security description on the left to the appropriate security feature on the right.

  Select and Place:

  

  

• Question 105:

  In policy-based routing, which action is taken for packets that do not match any of the route-map statements?

  A. forwarded after the egress queue empties on the outbound interface
  B. forwarded using the last statement in the route map
  C. forwarded using the closest matching route-map statement
  D. forwarded using destination-based routing
  D. forwarded using destination-based routing

  ---

  Each entry in a route map contains a combination of match and set statements. The match statements define the criteria for whether appropriate packets meet the particular policy (that is, the conditions to be met). The set clauses explain

  how the packets should be routed once they have met the match criteria.

  You can mark the route-map statements as permit or deny. You can interpret the statements as follows:

  ?If the statement is marked as permit and the packets meet the match criteria, the set clause is applied. One of these actions involves choosing the next hop. ?If a statement is marked as deny, the packets that meet the match criteria are sent

  back through the normal forwarding channels, and destination-based routing is performed. ?If the statement is marked as permit and the packets do not match any route-map statements, the packets are sent back through the normal

  forwarding channels, and destination-based routing is performed.

• Question 106:

  Which Cisco MDS feature needs to be enabled for Cisco TrustSec FC Link Encryption to work?

  A. feature FC-TSLE
  B. feature Trust-Sec
  C. feature FC-SP
  D. feature ESP
  E. feature DHCHAP
  C. feature FC-SP

• Question 107:

  Which statement about SNMP support on Cisco Nexus switches is true?

  A. Cisco NX-OS only supports SNMP over IPv4.
  B. Cisco NX-OS supports one instance of the SNMP per VDC.
  C. SNMP is not VRF-aware.
  D. SNMP requires the LAN_ENTERPRISE_SERVICES_PKG license.
  E. Only users belonging to the network operator RBAC role can assign SNMP groups.
  B. Cisco NX-OS supports one instance of the SNMP per VDC.

  ---

  Cisco NX-OS supports one instance of the SNMP per virtual device context (VDC). By default, Cisco NX-OS places you in the default VDC. SNMP supports multiple MIB module instances and maps them to logical network entities. SNMP is also VRF aware. You can configure SNMP to use a particular VRF to reach the SNMP notification host receiver. You can also configure SNMP to filter notifications to an SNMP host receiver based on the VRF where the notification occurred.

• Question 108:

  Which FCoE component is responsible for the encapsulation and de-encapsulation of Fibre Channel frames in Ethernet?

  A. distributed FCF
  B. FCoE node
  C. FCoE logical endpoint
  D. Fibre Channel forwarder
  E. FCoE forwarder
  C. FCoE logical endpoint

  ---

  The FCoE Logical Endpoint (FCoE_LEP) is responsible for the encapsulation and deencapsulation functions of the FCoE traffic. FCoE_LEP has the standard Fibre Channel layers, starting with FC-2 and continuing up the Fibre Channel Protocol stack.

• Question 109:

  Which option is a restriction of the unified ports on the Cisco UCS 6200 Series Fabric Interconnect when connecting to the unified fabric network?

  A. Direct FC connections are not supported to Cisco MDS switches
  B. The FCoE or Fibre Channel port allocations must be contiguous on the 6200.
  C. 10-G Fibre Channel ports only use SFP+ interfaces.
  D. vPC is not supported on the Ethernet ports.
  B. The FCoE or Fibre Channel port allocations must be contiguous on the 6200.

  ---

  When you configure the links between the Cisco UCS 2200 Series FEX and a Cisco UCS 6200 series fabric interconnect in fabric port channel mode, the available VIF namespace on the adapter varies depending on where the FEX uplinks are connected to the fabric interconnect ports. Inside the 6248 fabric interconnect there are six sets of eight contiguous ports, with each set of ports managed by a single chip. When uplinks are connected such that all of the uplinks from an FEX are connected to a set of ports managed by a single chip, Cisco UCS Manager maximizes the number of VIFs used in service profiles deployed on the blades in the chassis. If uplink connections from an IOM are distributed across ports managed by separate chips, the VIF count is decreased.
