Question 2

Which statement about a bridge domain is true?

  • A: A bridge domain must be linked to one internal network and one external network.
  • B: A bridge domain must be linked to a physical domain.
  • C: A bridge domain typically has at least one subnet that is associated with it.
  • D: A bridge domain must have at least one external network that is associated with it.

Correct Answer: A




Question 3

What are two advantages to running FabricPath in the data center over using Spanning Tree? (Choose two.)

  • A: provides multichassis EtherChannel capabilities
  • B: allows every switch to send BPDUs to each other to ensure the L2 topology is synchronized
  • C: has L2 multipath forwarding capabilities
  • D: uses 802.1q trunks to ensure VLANs are propagated through the topology
  • E: uses TTL field to provide loop mitigation

Correct Answer: CE

Efficiency and high performance − Because equal-cost multipath (ECMP) can be used the data plane, the network can use all the links available between any two devices. The first-generation hardware supporting Cisco FabricPath can perform 16-way ECMP, which, when combined with 16-port 10-Gbps PortChannels, represents bandwidth of 2.56 terabits per second (Tbps) between switches. 
Loop prevention and mitigation is available in the data plane, helping ensure safe forwarding that cannot be matched by any transparent bridging technology. Cisco FabricPath frames include a timeto-live (TTL) field similar to the one used in IP, and a reverse-path forwarding (RPF) check is also applied

Question 4

The APIC is responsible for which two processes? (Choose two.)

  • A: network policy configuration
  • B: fabric segmentation
  • C: BGP end-node emulation
  • D: ISL blocking per STP implementation
  • E: switch firmware management

Correct Answer: AE

The APIC is responsible for fabric activation, switch firmware management, network policy configuration, and instantiation. While the APIC acts as the centralized policy and network management engine for the fabric, it is completely removed from the data path, including the forwarding topology. Therefore, the fabric can still forward traffic even when communication with the APIC is lost.

Question 5

Which item in Cisco Unified Computing System is subject to finite state machine validation?

  • A: SNMP get
  • B: server boot
  • C: firmware downloads
  • D: server discovery

Correct Answer: D

An FSM is a workflow model, similar to a flow chart, that is composed of the following:
A finite number of stages (states) 
Transitions between those stages 
Operations 
The current stage in an FSM is determined by past stages and the operations performed to transition between the stages. A transition from one stage to another is dependent on the success or failure of an operation. 
Cisco UCS Manager uses FSM tasks that run in the Data Management Engine (DME) to manage end points in the Cisco UCS object model, including the following:
Physical components (chassis, I/O module, servers) 
Logical components (LAN cloud, policies) 
Workflows (server discovery, service profile management, downloads, upgrades, backups)

Question 6

Which management platform reduces server provisioning time by automatically performing an inventory and deep discovery when new devices are attached?

  • A: UCS Manager
  • B: UCS Server
  • C: CDP Manager
  • D: Enterprise Manager

Correct Answer: A

One of the main solution benefits is the reduction in server provisioning time. Whenever additional chassis are racked, stacked, and cabled and their server ports are configured, the Cisco UCS Manager will automatically perform an inventory and deep discovery of any subsequently attached equipment, without requiring manual intervention. Regardless of how many new chassis are connected, the discovery process would take about 10 minutes to discover all chassis in parallel and bring their physical resources in to the information tree under the Equipment tab.

Question 7

Which two are benefits of Cisco Unified Fabric? (Choose two.)

  • A: SNMPv3 strong authentication
  • B: reduced cabling
  • C: zone port distribution
  • D: consolidation of LAN and SAN over a common transport
  • E: native AES-256 encryption of data in flight

Correct Answer: BD




Question 8

A network engineer is migrating the server farm from 1 Gb/s Ethernet connectivity to 10 Gb/s Ethernet connectivity. 
What two Cisco Nexus Fabric Extenders support 10 Gb/s server connectivity? (Choose two.)

  • A: Nexus 2148T
  • B: Nexus 2232PP
  • C: Nexus 2248TP
  • D: Nexus 2248PQ
  • E: Nexus 2224TP

Correct Answer: AE

Question 9

Which option is a benefit of Unified Fabric Delivery to an IT organization?

  • A: lower total cost of ownership
  • B: reduced memory requirements
  • C: increased storage capacity
  • D: improved security

Correct Answer: A

Cisco Unified Fabric is the interconnection point for applications, stored data, and users that can help you:
Build an intelligent, high-performing infrastructure with multidimensional scalability for the data center network 
Simplify your data center architecture and reduce costs with LAN and SAN convergence, helping you reduce capital costs with fewer devices, simpler management, and more flexible configuration policies 
Create an open, programmable network backbone that is easier and faster to deploy and manage

Question 10

Which tool organizes workflows to automate simple and complex actions on infrastructure?

  • A: Cisco UCS Manager
  • B: Cisco UCS Director
  • C: Cisco DCNM
  • D: Cisco UCS server

Correct Answer: B

You can build Cisco UCS Director workflows to automate simple or complex provisioning and configuration processes.
