Cisco CCIE Data Center Written Set 3

1.

Which statement about the FCIP Tape Acceleration feature is true?

Cisco MDS SAN-OS provides only tape write acceleration. After receiving all the data, the host-side MDS FCIP Tape Acceleration-enabled switch proxies the successful completion of the SCSI WRITE operation. Cisco SAN-OS provides increased performance of data delivery to the remote FCIP connected tape drives by using UDP over the WAN. The FCIP Tape Acceleration feature can be used with multilink port channels if the port channels are constructed with a port channel protocol. WRITE FILEMARKS operations are proxied by the host-side MDS FCIP Tape Acceleration- enabled switch.

2.

Which statement about the SAN Extension Tuner is true?

The SET configuration is persistent across reboots. The virtual N Ports that are created will register the FC4 features that are supported with the name server. Only SCSI read and write commands are implemented. SET cannot be used if iSCSI is enabled. The data pattern that is used for the data that is generated between the virtual N Ports can be an all- zero pattern or an all-ones pattern. No other data patternscan be used.

3.

What is the benefit of the Priority-Based Flow control feature in Data Center Bridging?

provides the capability to manage a bursty, single traffic source on a multiprotocol link enables bandwidth management between traffic types for multiprotocol links addresses the problem of sustained congestion by moving corrective action to the network edge allows autoexchange of Ethernet parameters between switches and endpoints

4.

When an NP port becomes operational, the NP switch first logs itself into the core switch by sending a FLOGI request (using the port WWN of the NP port). What will occur next?

The switch registers with the fabric name server. The switch will perform a PLOGI to the port login server. The switch will register parameters using FDISC. The NPV switch will perform a PLOGI using FDISC to register with the fabric name server.

5.

What is the main function of the device-alias distribute command?

This command distributes the device alias configuration on the existing switch to all the other switches in the Cisco Fabric Services region. This command enables distribution and will send the configuration after a commit is executed. This command changes the distribution mode for device aliases. There is no such command.

6.

When a switch that supports enhanced zoning joins a fabric, which SW_ILS command does it use to determine the enhanced zoning capabilities of the other switches in the fabric?

MR ESS ELP EFP none of the above

7.

Which statement about the iSCSI initiator task tag is true?

The initiator assigns a task tag to each task it issues. The target assigns a task tag on behalf of the initiator. During the life of the task, this tag does not have to be unique. SCSI may not use this tag as part of the SCSI task identifier.

8.

Switchport mode trunk
Switchport trunk allowed vlan all
Channel-group 10 mode on

Channel-group 10 mode on
No shut
Interface port-channel10
Switchport mode trunk
Switchport allowed vlan all
No shut
Which Port Channel configuration must be used on the Nexus 1000v port-profile?

MAC pinning Cisco Discovery Protocol pinning Mode On Mode Active No port channel configuration

9.

What are the four vPath packet flow steps? (Choose four.)

enforce the action determined by the flow manager intercept packets on service enabled ports run packets through the vPath flow manager classify the packets flow manager emits an action for the packets

10.

Given the following configuration, what command can be used to determine the physical path that traffic will be sent out upon?
Port-profile type Ethernet name vm-data
Switchport mode trunk
Switchport trunk allowed vlan 200-210
Channel-group auto mode on mac-pinning
State enabled
Vmware port-group
No shut
Port-profile type vethernet name vlan-200
Switchport mode access
Switchport vlan 200
State enabled
Vmware port-group
No shut
