QUESTION 52

Which two items are required components of VN-Link in software? (Choose two.)

 

A.

VDC

B.

VEM

C.

vPC

D.

VSM

E.

VRRP

 

Correct Answer: BD

Explanation:

The Cisco Nexus 1000V Series consists of two main types of components that can virtually emulate a 66-slot modular Ethernet switch with redundant supervisor functions:

 

clip_image002Virtual Ethernet module (VEM)-data plane: This lightweight software component runs inside the hypervisor. It enables advanced networking and security features, performs switching between directly attached virtual machines, provides uplink capabilities to the rest of the network, and effectively replaces the vSwitch. Each hypervisor is embedded with one VEM.

clip_image002[1]Virtual supervisor module (VSM)-control plane: This standalone, external, physical or virtual appliance is responsible for the configuration, management, monitoring, and diagnostics of the overall Cisco Nexus 1000V Series system (that is, the combination of the VSM itself and all the VEMs it controls) as well as the integration with VMware vCenter. A single VSM can manage up to 64 VEMs. VSMs can be deployed in an active-standby model, helping ensure high availability.

QUESTION 53

Which two items are features that are available in VN-Link in software? (Choose two.)


 

A.

VM snapshot

B.

NetFlow

C.

ERSPAN

D.

high availability

E.

resource reservations

 

Correct Answer: BC

Explanation:

NetFlow is a feature that was introduced on Cisco routers that provides the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data provided by NetFlow, a network administrator can determine things such as the source and destination of traffic, class of service, and the causes of congestion. A typical flow monitoring setup (using NetFlow) consists of three main components:

 

clip_image002[2]Flow exporter: aggregates packets into flows and exports flow records towards one or more flow collectors.

clip_image002[3]Flow collector: responsible for reception, storage and pre-processing of flow data received from a flow exporter.

clip_image002[4]Analysis application: analyzes received flow data in the context of intrusion detection or traffic profiling,

 

This module describes how to configure Encapsulated Remote Switched Port Analyzer (ERSPAN). The Cisco ERSPAN feature allows you to monitor traffic on one or more ports or VLANs and send the monitored traffic to one or more destination ports.

QUESTION 54

Which command sequence correctly enables Adapter FEX on Nexus 5000 Series Switches?

 

A.

switch(config)# insta
ll feature-set virtualization switch(config)# feature-set virtualization

B.

switch(config)# install feature-set adapter-fex switch(config)# feature-set adapter-fex

C.

switch(config)# install feature-set adapter-fex switch(config)# feature-set virtualization

D.

switch(config)# install feature-set virtualization switch(config)# feature-set adapter-fex

 

Correct Answer: A

Explanation:

install feature-set virtualization : installs the cisco virtual machine feature set on the switch. feature-set virtualization : enables the cisco virtual machine feature on the switch.

QUESTION 55

Which three selections represent implementations of Cisco VN-Link technology? (Choose three.)

 

A.

Cisco Nexus 1000V

B.

Cisco Nexus 2000 FEX

C.

Cisco VM-FEX

D.

VMware PTS

E.

vMotion

 

Correct Answer: ACD

Explanation:

The VM is powered on and resides on the ESX Host 1 with all the information stored on the shared storage.

 

The VM was connected to the PODy (where y is the number of your POD) PTS VDS by associating it to port group VLAN61 that was create
d on the Cisco Nexus 5548 device. The VM has been connected to the vPC system automatically using a VN-Link in the hardware in PTS mode or in VM-FEX mode.

 

The VEM bits are used in PTS mode to connect the VM VNIC to the VMNIC interface.

 

In this case, the VMNIC interface is not a real VMNIC but a dynamic VNIC that is presented as an interface to the ESX OS. The dynamic VNIC is enabled when the Cisco UCS VIC creates and configures the VNIC parameters inherited from port group VLAN61.

QUESTION 56

When connecting Cisco Nexus 5000 Series Switches to the VMware vCenter Server, which item must be configured before installing the extension keys?

 

A.

configure vPC

B.

configure DirectPath I/O support in vCenter

C.

configure PTS on the VSM

D.

configure dynamic vNICs

 

Correct Answer: A

 

 

QUESTION 57

Which three VDC resources can be constrained with a resource template? (Choose three.)

 

A.

ACLs

B.

NAT entries

C.

IPv4 routes

D.

IPv6 routes

E.

SPAN sessions

F.

RBAC users

 

Correct Answer: CDE

Explanation:

VDC resource templates set the minimum and maximum limits for shared physical device resources when you create the VDC. The Cisco NX-OS software reserves the minimum limit for the resource to the VDC. Any resources allocated to the VDC beyond the minimum are based on the maximum limit and availability on the device. You can explicitly specify a VDC resource template, or you can use the default VDC template provided by the Cisco NX-OS software. VDC templates set limits on the following resources:

 

clip_image002[5]IPv4 multicast route memory

clip_image002[6]IPv6 multicast route memory

clip_image002[7]IPv4 unicast route memory

clip_image002[8]IPv6 unicast route memory

clip_image002[9]Port channels

clip_image002[10]Switch Port Analyzer (SPAN) sessions

clip_image002[11]VLANs

clip_image002[12]Virtual routing and forwarding instances (VRFs)

QUESTION 58

Which two Cisco Nexus platforms support Adapter FEX? (Choose two.)

 

A.

Cisco Nexus 7000 Series Switches

B.

Cisco Nexus 5000 Series Switches

C.

Cisco Nexus 5500 Series Switches

D.

Cisco Nexus 4000 Series Switches

E.

Cisco Nexus 2000 Series Fabric Extenders

 

Correct Answer: CE

Explanation:

At the access layer, the Adapter-FEX requires a FEX-enabled adapter on a server that connects to a parent device that supports virtualization of interfaces. The Adapter-FEX is supported on the following platforms:

 

clip_image002[13]The Cisco Unified Computing System (UCS) platform supports Adapter-FEX between UCS servers and the UCS Fabric Interconnect.

clip_image002[14]The Adapter-FEX is supported on the Cisco Nexus 5500 Series platform and on the Cisco Nexus 2200 Fabric Extender that is connected to a Cisco Nexus 5500 Series parent device. This implementation works on a variety of FEX-capable adapters, including the Cisco UCS P81E virtual interface card (VIC) adapter for the UCS C-Series platform and third party adapters such as the Broadcom BCM57712 Convergence Network Interface Card, that implement the virtual network tag (VNTag) technology.
