Practice Free 201-01 Riverbed Certified Solutions Associate - Network Performance Management Exam Questions Answers With Explanation

Cascade will send synthetic transactions to measure response time.

Cascade has a software agent that can be loaded on a Windows Server to provide response time metrics with most major applications

Cascade tracks Response Time metrics by observing live traffic. These metrics are used with other indicators to build baselines and analyze deviations that may be indicators to issues.

All the above.

Ensuring the interface of the Cascade Profiler is on the same subnet as the router, as NetFlow is not routable.

Using the “tcp/(n) + 1” port numbering scheme to ensure this router’s NetFlow is unique from all other routers.

Ensuring the router has IP connectivity to the Cascade Gateway.

Ensuring the interface of the Cascade Gateway is on the same subnet as the router, as NetFlow is not routable.

By setting 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.

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

The Performance Analytics are able to detect security threats such as host scans and worms.

The Cascade Profiler does not have two approaches

Yes, always.

It depends on whether all of the segments initialize their baseline.

It depends on what criteria was used when defining the dashboard widget.

It depends on which user defined and committed the Service.

It depends on how many Services have already been configured.

Through the serial port.

Through a keyboard and monitor connected to the appliance.

Through the Cascade Shark appliance Web Interface using the default Cascade Shark appliance IP Address.

Through the Cascade Shark appliance Web Interface if the IP address of Cascade Shark appliance is assigned through a DHCP server.

Many organizations do not know all the aspects of a given application or service they provide, which makes it difficult to fully map that service and monitor it from end to end. NetProfiler has visibility into many different areas and can often see connections used by different parts of a service that may be unknown to different administrators. This visibility allows NetProfiler to identify all the different components of a service and prov

When monitoring an application, it is often necessary to think of that application as a service instead of an application. By utilizing NetProfiler Services, you are able to take your application and easily convert it to a service. This conversion allows you to treat the application differently so it can be more effectively monitored.

Applications are large and complex and often traverse different groups within a single organization. Without the concept of a service in NetProfiler, it would not be possible to monitor the traffic from a single application since each group would have no purchase their own NetProfiler to monitor their individual aspect of the application.

None of the above.
