QUESTION 1 – (Topic 1)
Which statement about the Layer 3 card on the Cisco Nexus 5500 Series Switch is true?

A. BGP support is not provided, but RIP, EIGRP, and OSPF support is provided.
B. Up to two 4-port cards are supported with up to 160 Gb/s of Layer 3 forwarding capability.
C. Up to 16 FEX connections are supported.
D. Port channels cannot be configured as Layer 3 interfaces.

Answer: C

Explanation:
From the Cisco NX-OS 5.1(3)N1(1) release and later releases, each Cisco Nexus 5500 Series device can manage and support up to 24 FEXs without Layer 3. With Layer 3, the number of FEXs supported per Cisco Nexus 5500 Series device is 8. With Enhanced vPC and a dual-homed FEX topology each FEX is managed by both Cisco Nexus 5000 Series devices. As a result, one pair of Cisco Nexus 5500 Series devices can support up to 24 FEXs and 16 FEXs for Layer 2 and Layer 3.

QUESTION 2 – (Topic 1)
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.

Answer: B

Explanation:
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 3 – (Topic 1)
Which three items must be configured in the port profile client in Cisco UCS Manager? (Choose three.)

A. port profile
B. DVS
C. data center
D. folder
E. vCenter IP address
F. VM port group

Answer: B,C,D

Explanation:
After associating an ESX host to a DVS, you can migrate existing VMs from the vSwitch to the DVS, and you can create VMs to use the DVS instead of the vSwitch. With the hardware-based VN-Link implementation, when a VM uses the DVS, all VM traffic passes through the DVS and ASIC-based switching is performed by the fabric interconnect.
In Cisco UCS Manager, DVSes are organized in the following hierarchy: vCenter
Folder (optional)
Datacenter
Folder (required)
DVS
At the top of the hierarchy is the vCenter, which represents a VMware vCenter instance. Each vCenter contains one or more datacenters, and optionally vCenter folders with which you can organize the datacenters. Each datacenter contains one or more required
datacenter folders. Datacenter folders contain the DVSes.

QUESTION 4 – (Topic 1)
Which GLBP load-balancing algorithm ensures that a client is always mapped to the same VMAC address?

A. vmac-weighted
B. dedicated-vmac-mode
C. shortest-path and weighting
D. host-dependent

Answer: D

Explanation:
Host dependent—GLBP uses the MAC address of the host to determine which virtual MAC address to direct the host to use. This algorithm guarantees that a host gets the same virtual MAC address if the number of virtual forwarders does not change.
