C. Requires extensive IT skills

D. No operational expenditure

A large enterprise has virtualized heavily in their data center. All virtual machines in the enterprise are built from standardized baseline templates. Based on these image templates, they have set configuration best practices and implementation workflows.

Recently, the company has started to see performance issues on several production-critical virtual guests. In responding to the performance issues, the cause was found to be incorrectly configured vNIC parameters in the virtual guests.

Which service should be implemented to identify deviations in the deployed servers from the baseline templates, and to remediate any such deviations?

A. Change management reporting

B. CMDB automation

C. Policy-driven configuration management

D. Incident management runbook automation

A company has finished the design for their VDC. They realize that they should also include a few design considerations to prepare them for cloud.

What is a key technical reason for the company to build a cloud-based service?

A. Scale resources up and down to meet needs

B. Take advantage of multi-tenancy to improve utilization

C. Consolidate systems to increase density

D. Leverage auto-healing to reduce down-time

separate SAN fabrics. For ease of management, each fabric can only be configured with a single VSAN.

How should this environment be configured?

A. Blade server switches: NPV mode SAN core switches: NPIV mode

B. Blade server switches: NPIV mode SAN core switches: NPV mode

C. Blade server switches: NPV mode Storage edge switches: NPIV mode

D. Blade server switches: NPIV mode Storage edge switches: NPV mode

Which type of switch can provide management functions for virtual machine ports?

A. Distributed virtual switch

B. Standard virtual switch

C. Physical switch

D. Third-party virtual switch

Your VDC design calls for iSCSI adapters. In a meeting with the CIO, you are challenged about the planned capital expenditure for the iSCSI adapters. The CIO states that it would more cost-effective to purchase 10 Gigabit Ethernet NICs and use the integrated hypervisor software stack.

What effect will this have on the hypervisors?

A. Increased CPU load

B. Increased amount of I/O

C. Decreased amount of I/O

D. Decreased CPU load
