Question 520

A technician needs to inspect account names, UID values and login shells without expecting actual password hashes in that file. One student proposes Read the appropriate entries from /etc/passwd and another proposes Run id. Which technical comparison is the soundest?

  1. Read the appropriate entries from /etc/passwd is used because The passwd database lists account metadata and normally stores placeholder markers for passwords. The alternative Run id addresses effective user group IDs instead.
  2. Run id is more directly suited to account identity database than Read the appropriate entries from /etc/passwd, regardless of the stated constraint.
  3. The two actions are interchangeable for account identity database and necessarily have the same main result.
  4. Prefix the required command with sudo is the only useful action for account identity database; Read the appropriate entries from /etc/passwd has no relevant effect.

Explanation

Correct Answer

A:

Correct distinction: Read the appropriate entries from /etc/passwd targets account identity database; The passwd database lists account metadata and normally stores placeholder markers for passwords. The compared alternative instead serves effective user group IDs.

Incorrect Answers

B:

Incorrect mapping: Run id is used for effective user group IDs. It does not displace Read the appropriate entries from /etc/passwd for the described requirement.

C:

The mechanisms are different: The passwd database lists account metadata and normally stores placeholder markers for passwords. By contrast, id reports a user's identity numbers and associated group memberships. They are not universally interchangeable.

D:

The third option addresses run one privileged command: sudo executes a permitted command with delegated privileges under the system's sudo policy. The original action remains relevant because The passwd database lists account metadata and normally stores placeholder markers for passwords.

Question 521

A security analyst needs to identify the restricted file conventionally holding local password hashes. Which action most directly addresses this requirement on a Linux-related system?

  1. Run id
  2. Prefix the required command with sudo
  3. Identify /etc/shadow and enforce restricted access
  4. Run su - as an authorized user and authenticate as required

Explanation

Correct Answer

C:

Correct for protected password hash storage: The shadow file stores protected password hash and aging fields on typical shadow-password systems.

Incorrect Answers

A:

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

B:

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 protected password hash storage.

D:

This action targets root login shell switch: su - switches to the target user's login environment, typically root when unspecified. The stated task instead calls for protected password hash storage.

Question 522

An operator follows this instruction: Identify /etc/shadow and enforce restricted access. For the task described as "protected password hash storage", what is the most accurate expected result?

  1. id reports a user's identity numbers and associated group memberships.
  2. sudo executes a permitted command with delegated privileges under the system's sudo policy.
  3. su - switches to the target user's login environment, typically root when unspecified.
  4. The shadow file stores protected password hash and aging fields on typical shadow-password systems.

Explanation

Correct Answer

D:

Correct consequence of Identify /etc/shadow and enforce restricted access. This outcome explains its use for protected password hash storage.

Incorrect Answers

A:

This outcome belongs to effective user group IDs and would follow Run id; it is not the principal result of Identify /etc/shadow and enforce restricted access.

B:

This outcome belongs to run one privileged command and would follow Prefix the required command with sudo; it is not the principal result of Identify /etc/shadow and enforce restricted access.

C:

This outcome belongs to root login shell switch and would follow Run su - as an authorized user and authenticate as required; it is not the principal result of Identify /etc/shadow and enforce restricted access.

Question 523

A security analyst needs to identify the restricted file conventionally holding local password hashes. A teammate tries this different approach instead: Run id. The requirement is still unmet. Which corrective action should replace the misapplied approach?

  1. Identify /etc/shadow and enforce restricted access
  2. Run id
  3. Prefix the required command with sudo
  4. Run su - as an authorized user and authenticate as required

Explanation

Correct Answer

A:

Replace the attempt with this step: The shadow file stores protected password hash and aging fields on typical shadow-password systems. It fits protected password hash storage.

Incorrect Answers

B:

This step is specific to effective user group IDs: id reports a user's identity numbers and associated group memberships. It does not fix the stated requirement for protected password hash storage.

C:

This step is specific to run one privileged command: sudo executes a permitted command with delegated privileges under the system's sudo policy. It does not fix the stated requirement for protected password hash storage.

D:

This step is specific to root login shell switch: su - switches to the target user's login environment, typically root when unspecified. It does not fix the stated requirement for protected password hash storage.

Question 525

An administrator must create a new ordinary local account named trainee on a system with standard user-management tools. Which action most directly addresses this requirement on a Linux-related system?

  1. Run sudo passwd trainee and set the password interactively
  2. Run sudo groupadd editors
  3. Run sudo usermod -aG editors trainee
  4. Run sudo useradd trainee with needed account options

Explanation

Correct Answer

D:

Correct for create local user account: useradd creates a new local user database entry according to system defaults and supplied options.

Incorrect Answers

A:

This action targets set user authentication password: passwd changes the account's local authentication password using the configured PAM policy. The stated task instead calls for create local user account.

B:

This action targets create new group: groupadd creates a named group in the local group database. The stated task instead calls for create local user account.

C:

This action targets append supplemental group: The -aG combination appends a supplemental group instead of replacing the existing list. The stated task instead calls for create local user account.

Question 526

An operator follows this instruction: Run sudo useradd trainee with needed account options. For the task described as "create local user account", what is the most accurate expected result?

  1. useradd creates a new local user database entry according to system defaults and supplied options.
  2. passwd changes the account's local authentication password using the configured PAM policy.
  3. groupadd creates a named group in the local group database.
  4. The -aG combination appends a supplemental group instead of replacing the existing list.

Explanation

Correct Answer

A:

Correct consequence of Run sudo useradd trainee with needed account options. This outcome explains its use for create local user account.

Incorrect Answers

B:

This outcome belongs to set user authentication password and would follow Run sudo passwd trainee and set the password interactively; it is not the principal result of Run sudo useradd trainee with needed account options.

C:

This outcome belongs to create new group and would follow Run sudo groupadd editors; it is not the principal result of Run sudo useradd trainee with needed account options.

D:

This outcome belongs to append supplemental group and would follow Run sudo usermod -aG editors trainee; it is not the principal result of Run sudo useradd trainee with needed account options.
