  • C: Scheduler
  • D: Activity Planner
  • E: Predefined Tasks

Question 3

Which model is a deployment model in cloud computing?

  • A: automatic cloud
  • B: layered cloud
  • C: private cloud
  • D: collapsed cloud

Correct Answer: C

Cloud Deployment ModelsA cloud deployment model represents a specific type of cloud environment, primarily distinguished by ownership, size, and access. 
There are four common cloud deployment models:
Public Clouds 
Community Clouds 
Private Clouds 
Hybrid Clouds 
Other Deployment Models

Question 4

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 5

Which two options are primary elements of a tenant? (Choose two.)

  • A: firewall rules
  • B: contracts
  • C: EPG
  • D: access policies
  • E: switch domains

Correct Answer: BC

Tenants can be isolated from one another or can share resources. The primary elements that the tenant contains are filters, contracts, outside networks, bridge domains, contexts, and application profiles that contain endpoint groups (EPGs). Entities in the tenant inherit its policies.

Question 6

 

  

Refer to the exhibit. A network engineer allocates 12 physical ports to a new VDC. Which command is used to verify VDC port allocation on a Cisco Nexus switch?

  • A: show vdc port-membership
  • B: show vdc port-allocation
  • C: show vdc allocation
  • D: show vdc membership

Correct Answer: D

show vdc membership 
To display the interface membership information for the virtual device contexts (VDCs), use the show vdc membership command. 
show vdc membership [status]

Question 7

Which two protocols are encapsulated in FCoE? (Choose two.)

  • A: iSCSI
  • B: Fibre Channel
  • C: CIFS
  • D: NFS
  • E: SCSI

Correct Answer: BE

FCoE virtual links replace the physical Fibre Channel links by encapsulating Fibre Channel frames in Ethernet frames, and an FCoE virtual link is identified by the MAC addresses of the two FCoE endpoints.

Question 8

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 9

Which privilege is assigned by default to the UCS Manager Storage Administrator user role?

  • A: service-storage-security-config
  • B: service-admin-config
  • C: service-admin
  • D: service-profile-storage

Correct Answer: D

Question 10

Which two standards enable Ethernet to support FCoE? (Choose two.)

  • A: Priority Flow Control
  • B: Virtual Extensible LAN
  • C: Enhanced Transmission Selection
  • D: Address Resolution Protocol
  • E: virtual port channel and virtual device context

Correct Answer: AC

Enhancements to Ethernet The T11 organization’s FC-BB-5 standard defines FCoE, and also defines running FC over other media types. The IEEE 802.1 organization facilitates FCoE by defining enhancements to Ethernet. These enhancements fall under the DCB umbrella, specifically, three enabling standards for Ethernet to support FCoE:
Priority-based Flow Control (PFC) 
Enhanced Transmission Selection (ETS) 
Data Center Bridging Exchange (DCBX)
