1. What does pwd show?

  1. Current working directory
  2. All passwords
  3. A privilege grant
Show answer and explanation for question 1

Correct answer: A. Current working directory

pwd establishes path context.

2. Why quote a path with spaces?

  1. To change its permissions
  2. To pass it as one argument
  3. To encrypt it
Show answer and explanation for question 2

Correct answer: B. To pass it as one argument

The shell otherwise separates words.

3. What is better than chmod 777 as a blanket fix?

  1. Disable all logging
  2. Always use root
  3. Inspect identity and grant required minimum access
Show answer and explanation for question 3

Correct answer: C. Inspect identity and grant required minimum access

Access should match the intended task and identity.

4. Root can read a config, but the normal service user fails. What does the successful root read establish?

  1. That privileged process could read it in its context; service access still needs verification.
  2. The service must be using an incorrect password.
  3. Every service on the machine can read the config.
Show answer and explanation for question 4

Correct answer: A. That privileged process could read it in its context; service access still needs verification.

Effective identities and privileges differ. Inspect every path component under the service context, plus relevant ACL or isolation controls. A privileged read is weak evidence for ordinary service access.

5. The file is group-readable, but its parent directory is inaccessible to the service group. Which basic permission is relevant to reaching the file?

  1. World-write access on all parent directories.
  2. Directory search/execute access along the path.
  3. Execute permission on the configuration file.
Show answer and explanation for question 5

Correct answer: B. Directory search/execute access along the path.

Directory search permission is needed to traverse the path. Making a data file executable does not solve a parent traversal barrier; broad write access exceeds the read objective.
