Implementing Cisco Data Center Infrastructure (DCII) v6.0

QUESTION 71

Which example creates an Embedded Event Manager policy allowing the CLI command to execute, and triggers an SNMP notification when a user enters configuration mode?

 

A.

clip_image001

B.

clip_image002

C.

clip_image003

D.

clip_image004

 

Correct Answer: A

 

 

QUESTION 72

Between which two types of ports does FIP establish Fibre Channel virtual links? (Choose two.)

 

A.

VE Ports and VE Ports

B.

N Ports and F Ports

C.

VN Ports and VF Ports

D.

VP Ports and VE Ports

E.

VE Ports and VF Ports

F.

E Ports and E Ports

 

Correct Answer: AC

Explanation:FIP aims to establish virtual FC links between VN_Ports and VF_Ports (ENode to FCF), as well as between pairs of VE_Ports (FCF to FCF), since these are the only legal combinations supported by native Fibre Channel fabrics. Standards-compliant implementations are not required to support both forms of virtual FC links, and Cisco has decided to focus initially on implementing FIP only between ENodes and FCFs. FCF-to- FCF connectivity is considered a strategic direction for end-to-end FCoE deployments, but the short-term urgency is for FCoE adoption between CNAs and the Fibre Channel fabric perimeter, where unified fabric can offer the greatest capital expenditure (CapEx) savings today.

QUESTION 73

DRAG DROP

Drag the description on the left to the most appropriate FCoE protocol or feature on the right.

 

clip_image006

Correct Answer:

clip_image008

 

 

QUESTION 74

Which item represents the process that allows FCoE multihop using T11 standard FC-BB- 5?

 

A.

distributed FCF

B.

FIP proxy

C.

N Port proxy

D.

FIP snooping

 

Correct Answer: D

Explanation:FIP snooping is used in multi-hop FCoE environments. FIP snooping is a frame inspection method that can be used by FIP snooping capable DCB devices to monitor FIP frames and apply policies based on the information in those frames. This allows for:

Enhanced FCoE security (Prevents FCoE MAC spoofing.)

Creates FC point-to-point links within the Ethernet LAN

Allows auto-configuration of ACLs based on name server information read in the FIP frames

QUESTION 75

Which two statements about SAN zoning on Cisco Nexus switches are true? (Choose two.)

 

A.

Unlike configured zones, default zone information is not distributed to the other switches in the fabric.

B.

Traffic can either be permitted or denied among members of the default zone. This information is not distributed to all switches. It must be configured in each switch.

C.

The settings for default zone configurations cannot be changed.

D.

To activate a zone set, you must copy the running configuration to the startup configuration after the zone set is configured.

E.

Soft zoning restrictions will not prevent a source device from accessing a device outside its zone, if the source knows the Fibre Channel ID of the destination.

F.

Hard zoning is enforced by the hardware on each FLOGI sent by an N Port.

 

Correct Answer: BE

Explanation:Each member of a fabric (in effect a device attached to an Nx port) can belong to any zone. If a member is not part of any active zone, it is considered to be part of the default zone. Therefore, if no zone set is active in the fabric, all devices are considered to be in the default zone. Even though a member can belong to multiple zones, a member that is part of the default zone cannot be part of any other zone. The switch determines whether a port is a member of the default zone when the attached port comes up. Unlike configured zones, default zone information is not distributed to the other switches in the fabric Traffic can either be permitted or denied among members of the default zone. This information is not distributed to all switches; it must be configured in each switch.

QUESTION 76

Which FCoE component is responsible for the encapsulation and de-encapsulation of Fibre Channel frames in Ethernet?

 

A.

distributed FCF

B.

FCoE node

C.

FCoE logical endpoint

D.

Fibre Channel forwarder

E.

FCoE forwarder

 

Correct Answer: C

Explanation:The FCoE Logical Endpoint (FCoE_LEP) is responsible for the encapsulation and deencapsulation functions of the FCoE traffic. FCoE_LEP has the standard Fibre Channel layers, starting with FC-2 and continuing up the Fibre Channel Protocol stack.

QUESTION 77

Which four statements about reserved VLANs in Cisco NX-OS are true? (Choose four.)

 

A.

The range of reserved VLANs cannot be changed.

B.

The number of reserved VLANs is 96.

C.

A change to the range of reserved VLANs can be performed only in the VDC default.

D.

A write-erase procedure restores the default reserved VLAN range.

E.

The number of reserved VLANs is 128.

F.

A reload is needed for changes to take place.

G.

The configuration must be saved for changes to take place.

 

Correct Answer: CEFG

 

 

 

 

QUESTION 78

What configuration is required when implementing FCoE?

 

A.

disable LAN traffic on the interface

B.

configure PortFast on the access port

C.

permit all VLANs on the interface

D.

permit all VSANs on the interface

 

Correct Answer: A

Explanation:DCBX allows the switch to send a LAN Logical Link Status (LLS) message to a directly- connected CNA. Enter the shutdown lan command to send an LLS-Down message to the CNA. This command causes all VLANs on the interface that are not enabled for FCoE to be brought down. If a VLAN on the interface is enabled for FCoE, it continues to carry SAN traffic without any interruption.

QUESTION 79

In OTV, how are the VLANs split when a site has two edge devices?

 

A.

They are configured manually by user.

B.

They are split in half among each edge device.

C.

They are split as odd and even VLAN IDs on each edge device.

D.

It is not possible to have two edge devices in same site.

 

Correct Answer: C

 

 

QUESTION 80

How does addition of bandwidth between spine and leaf switches in a FabricPath architecture get utilized?

 

A.

Links between the same set of switches are automatically added to a port channel.

B.

Adding additional bandwidth is handled dynamically using the 802.1AX protocol.

C.

Traffic is load shared automatically across the available paths to the destination.

D.

FabricPath uses hardware bonding of physical interfaces to form higher-speed links.
