  A. Is either a BPF or Wireshark Display filter only.

  B. Can be created from a chart.

• Question 153:

  How many Group Types Can you create on your Cascade Profiler?

  B. 20

  C. 15

  D. 10

  E. Unlimited

  Correct Answer: D

• Question 154:

  One advantage of using a trace clip for analysis within Cascade Pilot instead of its parent capture job trace is:

  A. The trace clip is likely smaller in size, so views load faster.

  B. The trace clip is moved to the local system, so views load faster.

  C. The trace clip has a base set of views pre-applied, so analysis is faster.

  D. The trace clip is guaranteed to have trend/index data, so views load faster.

  Correct Answer: A

• Question 155:

  For Service policies that get applied to End User segments, by default separate policies are tracked by location for the client traffic. Which of the following is NOT true regarding flexibility in configuration of these End User segments?

  A. The default hostgroup type used can be changed from Configuration > General Settings.

  B. Different hostgroup types can be used for monitoring End User segments for each Service.

  C. While editing the Service one has the capability to select all sites or a subset of sites to include for monitoring.

  D. When adding a Service Health by Location widget to a dashboard, one has the capability to include all locations or a subset (maximum of 10).

  E. The default hostgroup type used for monitoring End User segments is ByLocation.

  Correct Answer: B

• Question 156:

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

  A. 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

  Correct Answer: A

• Question 157:

  How do all the Cascade components stay time synchronized?

  A. They all point to the same NTP server.

  B. The Profiler, ideally, points to an NTP server (although it can use local time as well), the Gateway and Sensor get their time information from the Profiler which acts as their NTP Server.

  C. For security reasons, all components use local time. The same time should be set on each component.

  D. They all synchronize their time via timestamps in Netflow sources.

  Correct Answer: B

• Question 158:

  To better analyze live traffic on Cascade Shark from Cascade Pilot you should:

  A. Apply a View on the live interface and then start a Capture Job on the capture port to analyze traffic later.

  B. Start a Capture Job on the capture port with a BPF filter and apply a View on the live interface for the same capture job.

  C. Start a Capture Job on the capture port, apply a View on the live interface and create a trace clip for the time window of interest.

  D. Never create a Capture Job to prevent packet drops.

  Correct Answer: C

• Question 159:
