A VDC architect has just purchased switches to be used as converged access layer switches. All Fibre Channel traffic operates at 8 Gbps and all ports operate at line-rate.
The design requires that all FC ports be configured as ISLs and be connected to the SAN core switches. An equal number of converged ports will be configured as standard Ethernet ports and connected to the aggregation layer switches.
What is the oversubscription ratio of the FC ports on this switch?
A. 3:1
B. 5:1
C. 6:1
D. 8:1
A project is assigned to a group of developers who have only weeks to develop a prototype for an online trading application. The application needs to run on a variety of virtual host compute systems and be accessible from anywhere. The project lead must select an environment that would allow for self-service, anywhere availability, wide scalability, and elasticity.
Which would be the best approach to meet their needs?
A. Outsource their infrastructure needs to a cloud provider that can meet their service-level requirements
B. Outsource their connectivity requirements and build their compute environment at a co- location facility
C. Construct a virtualized host compute environment with SAN storage and virtual network within their data center
D. Construct an internal cloud infrastructure group to build virtualized services to run, metered, within their organization
A large enterprise is in the process of converting to a virtual data center as a first step toward cloud computing.
They want the ability to deploy, manage, and decommission infrastructure components in a timely manner to meet their business requirements, with minimal impact to their systems administration staff.
What should be implemented?
A. Centralized resource pooling and management
B. Configuration management
C. Self-service request automation
D. Policy-driven configuration management
A company has invested in virtualization for all their non-mission critical applications and many mission critical applications. The company now wants to convert their virtualized silos that are still owned by each line-of business into a true VDC.
What is an important business outcome from this?
A. Reporting for management and chargeback
B. Workload right-sourcing
C. Dramatic reduction in energy consumption
D. Reduction in workforce
Which design consideration helps reduce risk when data is comingled across different business units in a VDC, or between different companies in the cloud?
A. Creating trust zones
B. Creating unique login IDs
C. Having a formal risk assessment process
D. Regulations that specify data that can be co-mingled
A hypervisor has been deployed with all virtual machines (VMs) sharing the same storage array LUN for their respective virtual disks. Array-based replication has been implemented for BC/DR. A restore of a single VM is now required.
What would happen if you attempt to recover an individual VM?
A. All VMs will be reverted.
B. Only the restored VM will need to be restarted.
C. None of the VMs will be restartable.
D. Only the restored VM will be reverted.
Which is a scale-out NAS solution that can distribute data over multiple nodes for resiliency?
A. EMC VPLEX
B. EMC Symmetrix VMAX
C. EMC Isilon
D. EMC VNX
An application processes test results from a manufacturing facility, then generates and archives quality reports. The application runs on an old, but still supported UNIX system. It was developed by an organization's IT department 10 years ago. While it has not been changed in over five years, the application source code and skills needed to modify it are still available internally.
What is this an example of?
A. A legacy application
B. Vendor lock-in
C. An enterprise application
D. Service-oriented architecture
A company has virtualized all their non-mission critical applications and many of their mission critical applications. They now want to convert those virtualized silos that are still owned by the lines of business into a true VDC.
What is an important technical capability gained from doing this?
A. Provisioning time is reduced by deploying standard services
B. A multi-tenant environment can be leveraged to deploy custom services
C. The data center is ready to deploy cloud services
D. Energy consumption is cut dramatically due to increased consolidation
What is the first phase of the Virtual Data Center Design Process?
A. Evaluate technology options
B. Create plan
C. Perform initial analysis
D. Gather data
