What is the purpose of a virtual switch?

D. Virtual switches present NICs to the UCSM for network connectivity

You disassociated a Database Server Service Profile from your existing UCS C240 M4. Then, you associate a Web Server Service Profile to this UCS C240M4. The Database Server Service Profile contained a Scrub Policy enabled for Disk Scrub. The Web Server Service Profile contains a Scrub Policy disabled for Disk Scrub.

What will happen after the reboot?

A. The process will fail because the Service Profiles are fundamentally different

B. The process will succeed, and server disk content will be preserved

C. The process will fail because of the differences in the Scrub Policies

D. The process will succeed, but server disk content will be lost

C. Cisco UCS Manager

D. Cisco UCS Central

What aspect of Cisco UCS servers enables multi-tenancy and provides an administrative hierarchy to organize resources?

A. Resource pools

B. Organizations

C. Service profile templates

D. Service profiles

You are creating a Local Disk Configuration Policy to be used by a new Service Profile for your UCS Server. Previous Service Profile had a Local Disk Configuration Policy set up for `No RAID' and the `Protect Configuration' box was checked. This time, you choose `RAID 1' and deselect the `Protect Configuration' checkbox.

What are the implications of this change?

A. The Service Profile association process will fail because you cannot change from `No RAID' to `RAID 1'

B. The Service Profile association process will fail because the policies are different and the `protect configuration' option was checked

C. The Service Profile association process will succeed, but your total disk capacity will be cut in half due to the change from RAID 0 to RAID 1

D. The Service Profile association process will succeed, but it will adopt the previous Local Disk Configuration Policy instead of the new one because it had `protect configuration' checked

ACME technologies is deploying a large number of similar UCS blade servers and want to be able to change servers policies at a later time on all blades.

What type of the Cisco UCS design is recommended?

A. Initial template based service profiles

B. Updating template based service profile

C. Updating non-template based service profiles

D. Initial non-template based service profiles

How many QoS classes are available to administrators on Cisco's UCS server?

Which additional three traffic egress controls may be enabled in Cisco UCS Manager depending upon the network adapter selected? (Choose three.)

A. Rate

B. Best Effort

C. Host Control

D. Peak

E. Burst

F. Smooth

An application is running in a data center as a set of virtual machines running on a single physical host. The host is using an NPIV enabled HBA.

What capability does this offer?

A. Only the physical host can logically connect to the SAN fabric, thus enhancing security.

B. The number of FlOGls is kept at a reasonable level, and therefore cannot saturate the SAN fabric.

C. Inter VSAN traffic can be switched directly by the HBA.

D. Each VM initiator can be managed independently, since it will generate its own FLOGl, and have its own pWWN.

In the context of Cisco's unified Computing System, which three Cisco best practices are recommended when creating WWN pools? (Choose three.)

A. All WWN must use "20" for the first octet

B. Define a standard convention for WWNs agreed upon by all stakeholders for address blocks

C. Select the default values presented by UCS Central

D. Use Cisco's OUI (00:25:B5) for the 3rd to 5th octets in WWN

E. Use the same hex value for 1st and 2nd octets in WWNN and WWPN

F. Engage the security team to request WWNs
