Question 510

An operator follows this instruction: Run who. For the task described as "current logged-in sessions", what is the most accurate expected result?

  1. who lists user login sessions recorded by the system.
  2. last displays records of past logins from the available system login database.
  3. The passwd database lists account metadata and normally stores placeholder markers for passwords.
  4. The shadow file stores protected password hash and aging fields on typical shadow-password systems.

Explanation

Correct Answer

A:

Correct consequence of Run who. This outcome explains its use for current logged-in sessions.

Incorrect Answers

B:

This outcome belongs to historical login sessions and would follow Run last; it is not the principal result of Run who.

C:

This outcome belongs to account identity database and would follow Read the appropriate entries from /etc/passwd; it is not the principal result of Run who.

D:

This outcome belongs to protected password hash storage and would follow Identify /etc/shadow and enforce restricted access; it is not the principal result of Run who.

Question 511

A help desk asks which users are currently logged into the Linux machine. A teammate tries this different approach instead: Run last. The requirement is still unmet. Which corrective action should replace the misapplied approach?

  1. Run last
  2. Run who
  3. Read the appropriate entries from /etc/passwd
  4. Identify /etc/shadow and enforce restricted access

Explanation

Correct Answer

B:

Replace the attempt with this step: who lists user login sessions recorded by the system. It fits current logged-in sessions.

Incorrect Answers

A:

This step is specific to historical login sessions: last displays records of past logins from the available system login database. It does not fix the stated requirement for current logged-in sessions.

C:

This step is specific to account identity database: The passwd database lists account metadata and normally stores placeholder markers for passwords. It does not fix the stated requirement for current logged-in sessions.

D:

This step is specific to protected password hash storage: The shadow file stores protected password hash and aging fields on typical shadow-password systems. It does not fix the stated requirement for current logged-in sessions.

Question 512

A help desk asks which users are currently logged into the Linux machine. One student proposes Run who and another proposes Read the appropriate entries from /etc/passwd. Which technical comparison is the soundest?

  1. Read the appropriate entries from /etc/passwd is more directly suited to current logged-in sessions than Run who, regardless of the stated constraint.
  2. The two actions are interchangeable for current logged-in sessions and necessarily have the same main result.
  3. Run who is used because who lists user login sessions recorded by the system. The alternative Read the appropriate entries from /etc/passwd addresses account identity database instead.
  4. Identify /etc/shadow and enforce restricted access is the only useful action for current logged-in sessions; Run who has no relevant effect.

Explanation

Correct Answer

C:

Correct distinction: Run who targets current logged-in sessions; who lists user login sessions recorded by the system. The compared alternative instead serves account identity database.

Incorrect Answers

A:

Incorrect mapping: Read the appropriate entries from /etc/passwd is used for account identity database. It does not displace Run who for the described requirement.

B:

The mechanisms are different: who lists user login sessions recorded by the system. By contrast, The passwd database lists account metadata and normally stores placeholder markers for passwords. They are not universally interchangeable.

D:

The third option addresses protected password hash storage: The shadow file stores protected password hash and aging fields on typical shadow-password systems. The original action remains relevant because who lists user login sessions recorded by the system.

Question 513

An investigator needs the system's recorded history of successful login sessions. Which action most directly addresses this requirement on a Linux-related system?

  1. Run last
  2. Read the appropriate entries from /etc/passwd
  3. Identify /etc/shadow and enforce restricted access
  4. Run id

Explanation

Correct Answer

A:

Correct for historical login sessions: last displays records of past logins from the available system login database.

Incorrect Answers

B:

This action targets account identity database: The passwd database lists account metadata and normally stores placeholder markers for passwords. The stated task instead calls for historical login sessions.

C:

This action targets protected password hash storage: The shadow file stores protected password hash and aging fields on typical shadow-password systems. The stated task instead calls for historical login sessions.

D:

This action targets effective user group IDs: id reports a user's identity numbers and associated group memberships. The stated task instead calls for historical login sessions.

Question 514

An operator follows this instruction: Run last. For the task described as "historical login sessions", what is the most accurate expected result?

  1. The passwd database lists account metadata and normally stores placeholder markers for passwords.
  2. last displays records of past logins from the available system login database.
  3. The shadow file stores protected password hash and aging fields on typical shadow-password systems.
  4. id reports a user's identity numbers and associated group memberships.

  1. Identify /etc/shadow and enforce restricted access is more directly suited to historical login sessions than Run last, regardless of the stated constraint.

Question 517

A technician needs to inspect account names, UID values and login shells without expecting actual password hashes in that file. Which action most directly addresses this requirement on a Linux-related system?

  1. Identify /etc/shadow and enforce restricted access
  2. Read the appropriate entries from /etc/passwd
  3. Run id
  4. Prefix the required command with sudo

Explanation

Correct Answer

B:

Correct for account identity database: The passwd database lists account metadata and normally stores placeholder markers for passwords.

Incorrect Answers

A:

This action targets protected password hash storage: The shadow file stores protected password hash and aging fields on typical shadow-password systems. The stated task instead calls for account identity database.

C:

This action targets effective user group IDs: id reports a user's identity numbers and associated group memberships. The stated task instead calls for account identity database.

D:

This action targets run one privileged command: sudo executes a permitted command with delegated privileges under the system's sudo policy. The stated task instead calls for account identity database.

Question 518

An operator follows this instruction: Read the appropriate entries from /etc/passwd. For the task described as "account identity database", what is the most accurate expected result?

  1. The shadow file stores protected password hash and aging fields on typical shadow-password systems.
