Demo Questions

Question 1
A customer has two Cisco UCS 6248 Fabric Interconnects in a cluster connected to one Cisco UCS 5108 Chassis via:
2 ports from the primary fabric interconnect to chassis 1, I/O module A 
2 ports from the secondary fabric interconnect to chassis 1, I/O module B 
The customer wants to ensure maximum redundancy and bandwidth. Within Cisco UCS Manager, how should the chassis discovery policy and link grouping be configured before the new chassis is discovered?

  • A: 4-link, none
  • B: 2-link, none
  • C: 2-link, port channel
  • D: 4-link. port channel
Correct Answer: C

Question 2
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 3
Which statement about EPGs is true?

  • A: EPGs can both provide and consume a contract.
  • B: EPGs can provide, but cannot consume a contract.
  • C: EPGs can consume, but cannot provide a contract.
  • D: EPGs neither provide or consume contracts.
Correct Answer: B
Contracts define inbound and outbound permit, deny, and QoS rules and policies such as redirect. Contracts allow both simple and complex definition of the way that an EPG communicates with other EPGs, depending on the requirements of the environment. Although contracts are enforced between EPGs, they are connected to EPGs using provider-consumer relationships. Essentially, one EPG provides a contract, and other EPGs consume that contract.

Question 4
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 5
Which two options are control plane protocols? (Choose two.)

  • A: BGP
  • B: ARP
  • C: NAT
  • D: SMTP
  • E: CoPP
Correct Answer: AB
The control plane: The control plane is the brain of the router. It consists of dynamic IP routing protocols (that is OSPF, IS-IS, BGP, and so on), the RIB, routing updates, in addition to other protocols such as PIM, IGMP, ICMP, ARP, BFD, LACP, and so on. In short, the control plane is responsible for maintaining sessions and exchanging protocol information with other router or network devices.

Question 6
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.

Question 7
Which two components are part of the Cisco Unified Computing System 2104 I/O Module? (Choose two.)

  • A: multiplexer
  • B: chassis management console
  • C: finite state machine
  • D: data management engine
  • E: chassis management controller
Correct Answer: AE



Question 8
Where does the data plane operate on a Cisco Nexus 7000 Series Switch?

  • A: supervisor module
  • B: unified crossbar fabric
  • C: unified port controller
  • D: Connectivity Management Processor
Correct Answer: B



Question 9
Which option describes Cisco’s virtual device context feature?

  • A: logical virtualization of a single physical switch
  • B: logical switches aggregated into a single physical switch
  • C: logical switches aggregated into multiple physical switches
  • D: multiple physical switches partitioned to a single virtual switch
Correct Answer: A
Cisco NX-OS introduces support for virtual device contexts (VDCs), which allows the switches to be virtualized at the device level. Each configured VDC presents itself as a unique device to connected users within the framework of that physical switch. The VDC runs as a separate logical entity within the switch, maintaining its own unique set of running software processes, having its own configuration, and being managed by a separate administrator.

Question 10
Layer 3 networks can be logically separated by which technology?

  • A: bridge domain
  • B: VRF
  • C: VLAN
  • D: tenant
Correct Answer: B
