Which technology can significantly reduce the network bandwidth required for backup?

You have been asked to diagnose a problem in your VDC. excessive latency and application timeouts on one hypervisor. The problem is known to be network related.
You examine the interface counters on the switch and find no abnormal activity. A packet analyzer
shows a significant number of CRC errors being generated by one of the NICs.
Which type of switch architecture is being used in this environment?

A company has two data centers located within 3 km of each other. They use EMC arrays at one
of the data centers; they use non-EMC storage at the other data center. They would like to have a
consistent view of one or more LUNs.
Which product should you suggest they deploy?

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 organizational reason for the company to build a cloud-based service?

You are designing a new VDC and are planning to use iSCSI for storage connectivity from the
hypervisors. The network infrastructure is 10 Gigabit Ethernet, and the storage system can
support multiple NICs.
Your networking design on the storage system must provide the highest level of performance,
security, and fault tolerance.
What should you recommend?

An architect is designing a VDC network environment, and is concerned about the overhead
introduced by the Spanning Tree Protocol. The environment will have approximately 2,500 VLANs
configured.

Which Spanning Tree Protocol should the architect specify for this implementation?

When selecting a hypervisor, which condition would favor choosing KVM?

From which resource are virtually provisioned LUNs allocated?

A small law firm that does not currently have any virtualization technologies implemented has

recently merged with another firm of approximately the same size. They are planning to
consolidate into a single location. They have decided to virtualize their servers and they would like
to consolidate storage. It has been determined that 80% of the file server data has not been
accessed in over 90 days.
What can they implement to achieve higher storage efficiency?

You are designing a new VDC and are planning to use iSCSI for storage connectivity from the
hypervisors. The network infrastructure is 10 Gigabit Ethernet, and the hypervisor hardware can
support only two NICs. Your networking design on the hypervisor must provide the highest level of
performance, security, and fault tolerance.
