You have a need to test network connectivity in a variety of environments to determine if your web site will respond fast enough and reliably enough to the requests from your mobile web-based application. You don't have the ability to create these environments within your test facilities.
What is the best option to use to conduct this testing?

  1. Find or develop a simulator that can simulate the network interaction of many devices on varied networks.
  2. Find or develop an emulator that can emulate the network interaction of many devices on varied networks.
  3. Find a cloud-based network simulator that can generate network traffic from a variety of different networks.
  4. Implement crowd-source testing to get a large number of people to use their own devices to connect via various networks.

Answer(s): C

Explanation:

C is correct. Cloud-based network simulators are commonly used for this purpose. A and B are not ideally suited for the problem and D would be too unreliable to control.



What is the best way to verify that a simulator is giving reliable results?

  1. Read the requirements
  2. Test the simulators
  3. Compare the results to the results from a real device
  4. Compare the results from the simulator to the results from an emulator

Answer(s): C

Explanation:

C is the best way to verify the reliability of the simulator. A as we all know may not tell us how the simulator really works. B would require knowing how the simulator should behave, which might be information we don't have. D would not make sense as you'd be comparing information from two different developed products.



Which cloud capability is most beneficial for performance testing?

  1. Supporting a variety of network types
  2. Supporting a variety of protocols
  3. Supporting a variety of device types
  4. Supporting a variety of device quantities and usages

Answer(s): D

Explanation:

D is correct as this is more beneficial for performance testing. Mixing any of the other three will help create a realistic load, but without D the others are not as useful.



Which of the following is a type of data that a mobile performance testing tool should be able to monitor, track and generate?

  1. Bursts of activity
  2. Usability information
  3. Navigation flow data
  4. Secure data transactions

Answer(s): A

Explanation:

A is correct. B and C deal with usability, not performance.
While D should be verified as part of security testing, it's not normally considered part of performance testing.
