Which statement explains why a Cisco UCS 6200 Fabric Interconnect that is configured in end-host mode is beneficial to the unified fabric network?
A. There is support for multiple (power of 2) uplinks.
B. Upstream Layer 2 disjoint networks will remain separated.
C. The 6200 can connect directly via vPC to a Layer 3 aggregation device.
D. STP is not required on the uplink ports from the 6200.
Correct Answer: D
In Cisco Unified Computing System environments, two Ethernet switching modes determine the way that the fabric interconnects behave as switching devices between the servers and the network. In end-host mode, the fabric interconnects appear to the upstream devices as end hosts with multiple links. In end-host mode, the switch does not run Spanning Tree Protocol and avoids loops by following a set of rules for traffic forwarding. In switch mode, the switch runs Spanning Tree Protocol to avoid loops, and broadcast and multicast packets are handled in the traditional way.
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.
Correct Answer: C
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
Which three items must be configured in the port profile client in Cisco UCS Manager? (Choose three.)
A. port profile
C. data center
E. vCenter IP address
F. VM port group
Correct Answer: BCD
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:
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.

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
Correct Answer: AC
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.

Which policy-map action performs congestion avoidance?
Correct Answer: D
Congestion avoidance techniques monitor network traffic loads in an effort to anticipate and avoid congestion at common network bottlenecks. Congestion avoidance is achieved through packet dropping. Among the more commonly used congestion avoidance mechanisms is Random Early Detection (RED), which is optimum for high-speed transit networks. Cisco IOS QoS includes an implementation of RED that, when configured, controls when the router drops packets. If you do not configure Weighted Random Early Detection (WRED), the router uses the cruder default packet drop mechanism called tail drop.
