NEW QUESTION 29
User response time in AppResponse is the sum of which five metrics?
- A. Outbound Round Trip Time, Request Payload Transfer Time, Server Response Time, Response Payload Transfer Time, Total Retransmission Delay
- B. Connection Setup Time, Request Payload Transfer Time, Server Response Time, Response Payload Transfer Time, Total Retransmission Delay
- C. Inbound Round Trip Time, Request Payload Transfer Time, Server Response Time, Response Payload Transfer Time, Total Retransmission Delay
- D. Inbound Round Trip Time, Outbound Round Trip Time, Server Response Time, Request Payload Transfer Time, Total Retransmission Delay
Answer: B
Explanation:
User Response Time is a sum of the averages of the following four metrics: "Connection Setup Time [msec]" + "Server Response Time [msec]" + "Total Payload Transfer Time [msec]" + "Total Retrans Delay [msec]". User Response Time estimates the average time for an application to process a TCP data request, and thus is a good measure of end-user response time.
NEW QUESTION 30
Which of the following best describes Microflow Index Data in AppResponse?
- A. Raw packets
- B. Data required for export to WireShark or Transaction Analyzer
- C. Packet data required for offline analysis
- D. Summary information about conversations based on packets
Answer: D
Explanation:
The Microflow Indexing section of the tab specifies limits for the storage of Microflow indexes. Microflow Indexing captures summary information about conversations between devices on the network. This information is all that is needed by the Packet Analyzer software to calculate many of the View metrics that describe the traffic stream. Because it is already in summary form, processing of Microflow Indexing data for View metrics is very fast.
NEW QUESTION 31

- A. Day of the week and week of the month
- B. Month of the quarter and quarter of the year
- C. Time of day and day of the week

NEW QUESTION 32
Which host group type is used by default for the End User component in NetProfiler Service definitions?
- A. Any combination of user defined groups from multiple group types
- B. ByApp
- C. ByInternalHosts
- D. ByLocation
Answer: D
Explanation:
The default selection is the ByLocation group type. If you want to use the ByLocation group type for determining how end user components are tracked and reported, then ensure that the groups of that group type associate IP addresses with the locations you want to track.
If you have a large network, it may be desirable to track and report end users by region, rather than by individual location. In this case, you may prefer to create a ByRegion group type for managing services. In this new group type you might define regional groups instead of using smaller geographical locations.
The group type selection you make on the Configuration > General Settings page is applied to all service definitions. It determines how end-user service components are grouped on dashboards and reports. You should choose this group type carefully because historical data for services will be lost if you must change the group type later.
