Software Testing and Quality Control Questions

Multiple choice technology security

When do we need to be penetration testing

  1. After integration testing but before acceptance testing by the client/end user

  2. after unit test

  3. after integration testing

  4. during system testing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Penetration testing is typically conducted after integration testing is complete and the system is fully functional, but before user acceptance testing (UAT) or final release. Testing earlier (like unit testing) is premature, and doing it during system testing is less comprehensive.

Multiple choice technology security

The kind of testing in which activities are performed to find the active machines, open ports and available services, identifying the OS and mapping the network

  1. Passive Scanning

  2. Social Engineering

  3. Scanning

  4. Fuzzing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

To solve this question, the user needs to know the different types of testing techniques used in cybersecurity. The user must identify the type of testing in which activities are performed to find active machines, open ports, available services, identifying the OS, and mapping the network.

Now, let's go through each option and explain why it is right or wrong:

A. Passive Scanning: This option is incorrect because passive scanning is a type of testing in which the tester monitors network traffic and collects data without actively engaging with the network.

B. Social Engineering: This option is incorrect because social engineering is a type of attack that exploits human behavior to gain access to systems or information.

C. Scanning: This option is correct. Scanning is a type of testing that involves actively probing a network to identify active machines, open ports, available services, identifying the OS, and mapping the network.

D. Fuzzing: This option is incorrect because fuzzing is a type of testing that involves sending random or invalid data to a system to identify vulnerabilities.

The Answer is: C

Multiple choice technology security

Which tool can be used for system vulnerability test

  1. Nessus

  2. HP Web Inspect

  3. TAM

  4. SDL
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The correct answer is A. Nessus.

Nessus is a widely used tool for system vulnerability testing. It helps identify and assess vulnerabilities in various systems and networks. It performs scans to detect potential weaknesses and provides detailed reports on the vulnerabilities found. Nessus is known for its extensive vulnerability database and its ability to perform comprehensive security assessments.

Options B, C, and D are not specifically designed for system vulnerability testing:

B. HP Web Inspect: HP Web Inspect is a web application security testing tool that focuses on identifying vulnerabilities in web applications, rather than system vulnerabilities.

C. TAM: It is unclear what "TAM" refers to in this context. Without more information, it is difficult to determine if it is a tool suitable for system vulnerability testing.

D. SDL: SDL stands for "Security Development Lifecycle," which is a methodology for developing secure software. It is not a specific tool used for system vulnerability testing.

Therefore, option A, Nessus, is the most appropriate tool for system vulnerability testing.

Multiple choice technology security

When you are performing EQA of an application developed by another project, you are doing

  1. white box testing

  2. black box testing

  3. security testing

  4. vulnerability testing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When performing EQA (External Quality Assurance) on an application developed by another team, you have access to the source code and internal architecture. This visibility into the codebase allows you to examine code structure, dependencies, and internal logic, which characterizes white box testing rather than black box testing.

Multiple choice

The statements executed before the condition are tested in

  1. Do While……..loop

  2. Do loop While…………

  3. For……….Next loop

  4. For Each …………Next Loop
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In Do...Loop While, the statements execute first, then the condition is tested. This guarantees at least one execution, unlike Do While...Loop where the condition is tested before execution.

Multiple choice

The following program is to be tested for statement coverage: begin if (a = = b) {S1; exit;} else if (c = = d) {S2;} else {S3; exit;} S4; end The test cases T1, T2, T3 and T4 given below are expressed in terms of the properties satisfied by the values of variables a, b, c and d. The exact values are not given. T1 : a, b, c and d are all equal T2 : a, b, c and d are all distinct T3 : a=b and c !=d T4 : a !=b and c=d

Which of the test suites given below ensures coverage of statements S1, S2, S3 and S4?

  1. T1, T2, T3

  2. T2, T4

  3. T3, T4

  4. T1, T2, T4

Multiple choice

The tester now tests the program on all input strings of length five consisting of characters ‘a’, ‘b’, ‘c’, ‘d’ and ‘e’ with duplicates allowed. If the tester carries out this testing with the four test cases given above, how many test cases will be able to capture the flaw?

  1. Only one

  2. Only two

  3. Only three

  4. All four
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Flaw in this given procedure is that one character of Array ‘A’ that can be replaced by more than one characters of 'newc' array, which should not be so. Test cases (3) and (4) identify this flaw as they are containing ‘oldc’ and ‘newc’ array characters arranged in specific manner. Following string can reflect flaw, if tested by test case (3).

Likewise, single character ‘b’ in A is replaced by ‘c’ and then by ‘d’. Same way, test case (4) can also catch the flaw.
