Questions Related to performance

During analysis of a scenario, you realize that the throughput becomes flat as Vusers continue to increase. What is the likely cause?

  1. Bandwidth problem

  2. A database server problem

  3. A web server connection problem

  4. An application server connection problem


Correct Option: A

Which Analysis graph shows the number of transactions against transaction response times?

  1. Transactions per Second

  2. Average Transaction Response Time

  3. Transaction Response Time Under Load

  4. Transaction Response Time (distribution)


Correct Option: D

AI Explanation

To answer this question, you need to understand the different types of analysis graphs commonly used in performance testing.

Option A) Transactions per Second - This graph shows the number of transactions executed per second. It does not directly show the transaction response times.

Option B) Average Transaction Response Time - This graph shows the average response time of transactions over a period of time. It does not directly show the number of transactions against response times.

Option C) Transaction Response Time Under Load - This graph shows how the response time of transactions changes under different levels of load. It does not directly show the number of transactions against response times.

Option D) Transaction Response Time (distribution) - This graph shows the distribution of transaction response times. It displays the number of transactions against their respective response times. It is the correct answer because it directly shows the number of transactions against transaction response times.

The correct answer is D) Transaction Response Time (distribution). This option is correct because it specifically represents the number of transactions against transaction response times.

Which HTTP error code indicates that an individual business process is failing under load or the web application itself has crashed?

  1. 400

  2. 401

  3. 403

  4. 500


Correct Option: D

What could be the possible reason/reasons for poor response time bottleneck

  1. • High percentage of CPU usage

  2. • Poor logical database design, such as bad table design

  3. • Inefficient session and state management

  4. • High queue length on server side


Correct Option: B,C,D

Which one amongst the following is not the important performance counter for identifying Memory related bottleneck

  1. Available Memory Bytes

  2. Committed Memory Bytes

  3. Memory Pages / seconds

  4. % User Time


Correct Option: D

What is the recommended transaction monitoring frequency

  1. 5 Seconds

  2. 10 Seconds

  3. 15 Seconds

  4. 30 Seconds


Correct Option: B
  1. • To let all Vusers stop at once

  2. To gradually release resources of the system after a heavy load

  3. To monitor Performance Center servers

  4. None of these


Correct Option: B
  1. Disk sec / Transfer

  2. Network Interface\ Bytes Total/sec

  3. Server\ Bytes Received/sec

  4. Packets Received Errors


Correct Option: A
  1. monitor just the Database server

  2. monitor just the Application server

  3. monitor all system components present in your AUT

  4. use the performance summary instead of monitoring individual components


Correct Option: C
