C.

A 3rd party virtual switch is required such as the CISCO Nexus 1000v as no standard vSwitch exists with ESXi

D.

The included standard vSwitch of the CISCO Nexus 7000

E.

The included standard vSwitch or the CISCO Nexus 1000v

In Cascade Profiler, what is the minimum amount of historical flow data required for an Application Performance analytic to initialize?

A.

Three weeks

B.

Three days

C.

One day

D.

Configurable from one minute to three weeks

How do Cascade Performance Analytics assist with Performance Monitoring?

A.

By setting intelligent static thresholds for Application metrics and Interface metrics, tolerance can be determined. Cascade will use these thresholds and tolerances to report on deviations indicative of performance problems.

B.

The Customer only needs to identify their critical hosts, interfaces and/or applications, and Cascade will automatically baseline their behavior and report on deviations indicative of performance problems.

C.

The Performance Analytics use knowledge of hosts, interfaces, and/or applications are able to detect security threats such as host scans and worms.

D.

After baselining is completed, Cascade can re-route congested traffic to avoid congested application delivery paths.

On the Cascade Shark appliance, packet de-duplication should be enabled when:

Capturing packets from a SPAN-Port/Port-Mirror whose configuration may generate duplicate packets

B.

Capturing packets from an aggregating TAP

C.

Removing duplicate flows across multiple interfaces

D.

Capturing packets from a 10GB link

B.

sourceIP, destIP, protocol, destPort

C.

sourceIP, destIP, protocol, sourcePort, destPort

D.

destIP, protocol, destPort

E.
