  C. This feature allows the binding of the same WWNN from the pool to the vHBA, even across reboots.
  D. This feature allows the binding of the Fibre Channel uplink to the vHBA, even across reboots.
  A. This feature allows the binding of the SCSI targets to the vHBA, even across reboots.

• Question 93:

  B. Specific VLANs are trunked on specific uplinks.
  C. UDLD is enabled.
  D. UDLD is disabled.
  E. Cisco Discovery Protocol is enabled.
  F. Cisco Discovery Protocol is disabled.
  G. They connect to the I/O modules.
  A. When a VLAN is configured, it is trunked on all uplinks.
  D. UDLD is disabled.
  E. Cisco Discovery Protocol is enabled.

• Question 94:

  Which two policies can specify that a port channel be configured between the fabric extender and fabric interconnect? (Choose two.)

  A. chassis or fabric extender discovery policy
  B. rack server discovery policy
  C. rack management connection policy
  D. server inheritance policies
  E. autoconfig policies
  F. chassis connectivity policy
  A. chassis or fabric extender discovery policy

• Question 95:

  Which of the following scenarios accurately demonstrate how the Cisco Unified Computing System ensures that a firmware upgrade is minimally disruptive to the data center unified fabric?

  A. If an I/O module is upgraded to a version that is incompatible with its fabric interconnect, the fabric interconnect can automatically reactivate the I/O module to a compatible version.
  B. If components like server BIOS, HBA, and RAID controller firmware are unsuccessfully updated through direct firmware updates, the update process will fall back to a host firmware package that is associated with the service profile.
  C. If an update of the subordinate fabric interconnect leaves it in a nonusable state, the primary fabric interconnect will automatically be updated to ensure that one fabric interconnect is running the most recent firmware.
  D. After Cisco Unified Computing System Manager upgrades the subordinate node, only then is the active management node automatically synchronized.
  A. If an I/O module is upgraded to a version that is incompatible with its fabric interconnect, the fabric interconnect can automatically reactivate the I/O module to a compatible version.

• Question 96:

  Which two are true with respect to the upgrade process for the Cisco Unified Computing System? (Choose two.)

  A. For easier manageability, Cisco provides one full bundle that contains the firmware images for all Cisco Unified Computing System components.
  B. You can choose from FTP, TFTP, SCP, and HTTP to copy the bundle image from a remote file system.
  C. When the bundle image is downloaded, it must be transferred to the flash file system of the active fabric interconnect.
  D. When the download is successful, Cisco Unified Computing System Manager expands the individual files from the archive and installs them in the correct flash file system partition.
  E. It is strongly recommended that you activate all components in all chassis at one time.
  F. The I/O module, CIMC, and adaptors update process operates strictly on the backup partition of Flash for a given component.
  C. When the bundle image is downloaded, it must be transferred to the flash file system of the active fabric interconnect.
  F. The I/O module, CIMC, and adaptors update process operates strictly on the backup partition of Flash for a given component.

• Question 97:

  Which consideration must be made while performing backup operations within the Cisco UCS Manager?

  A. Each backup destination can have multiple backup operations.
  B. Backups can be scheduled ahead of time.
  C. A user can perform incremental backups of a system configuration.
  D. Rerunning an existing backup operation overwrites the existing backup file.
  D. Rerunning an existing backup operation overwrites the existing backup file.

• Question 98:

  Refer to the exhibit.

  

  You are configuring a Cisco UCS Fabric Interconnect. You associate a blade server to a service profile that has the Testing boot policy. Which statement describes the result of the configuration?

  A. The iSCSI boot was created for the LAN boot policy.
  B. The blade server fails to boot due to a missing configuration line of set order 0.
  C. The blade server first tries to boot by using vHBA3 across the SAN network.
  D. The blade server first tries to boot from the local storage, and if this fails, it boots from vHBA3.
  C. The blade server first tries to boot by using vHBA3 across the SAN network.

• Question 99:

  Which option describes the difference between "high-performance" and "none" on a VM- FEX port profile?

  A. None is software assisted, and high-performance is software and hardware assisted.
  B. None indicates that VM-FEX is not used on this interface, and high-performance indicates that is used.
  C. None is used for management profiles, and high-performance is used for mission-critical data profiles.
  D. None assumes default scheduling settings for the port profile, and high-performance gives the ports priority in scheduling.
  A. None is software assisted, and high-performance is software and hardware assisted.
