Implementing Cisco Data Center Unified Computing

Question No: 1

Which of the following are true concerning authentication within a Cisco Unified Computing System?

  1. Authentication domains are used to leverage individual authentication systems.

  2. You can create up to 64 authentication domains, each associated with a provider group and realm in Cisco Unified Computing System Manager.

  3. At login, the user can select the authentication domain to be used.

  4. Cisco Unified Computing System supports LDAP or RADIUS for remote authentication.

  5. A locally authenticated user account is authenticated directly through the fabric interconnect.

Answer: E

Question No: 2

You have a Cisco UCS B200 M2 server configured with 12 4-GB DDR3 1333-MHz dual- voltage memory DIMMs. You learned that the server memory speed is running at 1066 MHz instead. How can you configure the server to run at maximum memory speed?

  1. You cannot configure memory speed of 1333 MHz. The maximum memory speed of a Cisco UCS B200 M2 server with 12 4-GB DIMM is 1066 MHz.

  2. Memory speed of the ESX host is configurable on VMware vCenter.

  3. Create a BIOS policy. In the RAS Memory BIOS settings, select Performance Mode for LV DDR Mode.

  4. On the CIMC of the Cisco UCS B200 M2, select 1333 MHz in the Memory Speed option.

Answer: C

Question No: 3

Question No: 5

The Cisco UCS administrator has the chassis discovery policy set to quot;2-linkquot;. The administrator connects a new chassis to the Cisco UCS 6200 Series Fabric Interconnects using four links. Which option about link utilization is true?

  1. The Cisco UCS will use two links until the chassis is reacknowledged, after which it will use all four links.

  2. The Cisco UCS will use all four links for discovery.

  3. The Cisco UCS will use only two links. The other two links are unusable.

  4. The Cisco UCS will use only two links. However, the administrator can manually pin traffic to the extra links by using service profiles.

Answer: A

Question No: 6

Which statement about Cisco Integrated Management Controller secure mode is true?

  1. After you enable it, you cannot disable it.

  2. After you enable it, you cannot downgrade the Cisco Integrated Management Controller firmware.

  3. It verifies the OS before allowing it to boot.

  4. The server must reboot to apply.

Answer: A

Question No: 7

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?

  1. 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.

  2. 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.

  3. 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.

  4. After Cisco Unified Computing System Manager upgrades the subordinate node, only then is the active management node automatically synchronized.

Answer: A
