Demo Questions

Question 1

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)

Question 2

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 3

What are two main benefits of standardized open API’s in a multi-vendor environment? (Choose two.)

  • A: automation
  • B: clustering
  • C: interoperability
  • D: centralized management
  • E: configuration management

Correct Answer: AD




Question 4

Which device connects Cisco UCS B-Series to Cisco Fabric Switches?

  • A: Fabric Extender
  • B: a host bus adapter
  • C: Fabric Interconnects
  • D: a fabric switch

Correct Answer: B




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 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.
