Question 570

An operator follows this instruction: Run sudo chown alice notes.txt. For the task described as "change file owner", what is the most accurate expected result?

  1. chgrp changes group ownership without changing the file's owning user.
  2. Directory execute permission permits path traversal or searching entries by name.
  3. A 027 mask removes group write and all other permissions from newly created file/directory modes.
  4. chown changes the ownership UID associated with the file.

Explanation

Correct Answer

D:

Correct consequence of Run sudo chown alice notes.txt. This outcome explains its use for change file owner.

Incorrect Answers

A:

This outcome belongs to change owning group and would follow Run sudo chgrp editors notes.txt; it is not the principal result of Run sudo chown alice notes.txt.

B:

This outcome belongs to directory traverse permission and would follow Grant appropriate execute permission on the directory after authorization; it is not the principal result of Run sudo chown alice notes.txt.

C:

This outcome belongs to restrict default creation mask and would follow Set umask 027 in the shell session; it is not the principal result of Run sudo chown alice notes.txt.

Question 571

An administrator must transfer file ownership of notes.txt to user alice rather than changing permissions only. A teammate tries this different approach instead: Run sudo chgrp editors notes.txt. The requirement is still unmet. Which corrective action should replace the misapplied approach?

  1. Run sudo chown alice notes.txt
  2. Run sudo chgrp editors notes.txt
  3. Grant appropriate execute permission on the directory after authorization
  4. Set umask 027 in the shell session

Explanation

Correct Answer

A:

Replace the attempt with this step: chown changes the ownership UID associated with the file. It fits change file owner.

Incorrect Answers

B:

This step is specific to change owning group: chgrp changes group ownership without changing the file's owning user. It does not fix the stated requirement for change file owner.

C:

This step is specific to directory traverse permission: Directory execute permission permits path traversal or searching entries by name. It does not fix the stated requirement for change file owner.

D:

This step is specific to restrict default creation mask: A 027 mask removes group write and all other permissions from newly created file/directory modes. It does not fix the stated requirement for change file owner.

Question 572

An administrator must transfer file ownership of notes.txt to user alice rather than changing permissions only. One student proposes Run sudo chown alice notes.txt and another proposes Grant appropriate execute permission on the directory after authorization. Which technical comparison is the soundest?

  1. Grant appropriate execute permission on the directory after authorization is more directly suited to change file owner than Run sudo chown alice notes.txt, regardless of the stated constraint.
  2. Run sudo chown alice notes.txt is used because chown changes the ownership UID associated with the file. The alternative Grant appropriate execute permission on the directory after authorization addresses directory traverse permission instead.
  3. The two actions are interchangeable for change file owner and necessarily have the same main result.
  4. Set umask 027 in the shell session is the only useful action for change file owner; Run sudo chown alice notes.txt has no relevant effect.

Explanation

Correct Answer

B:

Correct distinction: Run sudo chown alice notes.txt targets change file owner; chown changes the ownership UID associated with the file. The compared alternative instead serves directory traverse permission.

Incorrect Answers

A:

Incorrect mapping: Grant appropriate execute permission on the directory after authorization is used for directory traverse permission. It does not displace Run sudo chown alice notes.txt for the described requirement.

C:

The mechanisms are different: chown changes the ownership UID associated with the file. By contrast, Directory execute permission permits path traversal or searching entries by name. They are not universally interchangeable.

D:

The third option addresses restrict default creation mask: A 027 mask removes group write and all other permissions from newly created file/directory modes. The original action remains relevant because chown changes the ownership UID associated with the file.

Question 573

A collaborative file must be assigned to the editors group while retaining its existing user owner. Which action most directly addresses this requirement on a Linux-related system?

  1. Grant appropriate execute permission on the directory after authorization
  2. Set umask 027 in the shell session
  3. Run ls -l target.txt
  4. Run sudo chgrp editors notes.txt

Explanation

Correct Answer

D:

Correct for change owning group: chgrp changes group ownership without changing the file's owning user.

Incorrect Answers

A:

This action targets directory traverse permission: Directory execute permission permits path traversal or searching entries by name. The stated task instead calls for change owning group.

B:

This action targets restrict default creation mask: A 027 mask removes group write and all other permissions from newly created file/directory modes. The stated task instead calls for change owning group.

C:

This action targets inspect rwx permission bits: The long listing displays the rwx mode string and owner/group columns. The stated task instead calls for change owning group.

Question 574

An operator follows this instruction: Run sudo chgrp editors notes.txt. For the task described as "change owning group", what is the most accurate expected result?

  1. chgrp changes group ownership without changing the file's owning user.
  2. Directory execute permission permits path traversal or searching entries by name.
  3. A 027 mask removes group write and all other permissions from newly created file/directory modes.
  4. The long listing displays the rwx mode string and owner/group columns.

Question 577

A user has read permission on a directory but cannot reach a known file path within it. Which action most directly addresses this requirement on a Linux-related system?

  1. Grant appropriate execute permission on the directory after authorization
  2. Set umask 027 in the shell session
  3. Run ls -l target.txt
  4. Run chmod u+x deploy.sh

Explanation

Correct Answer

A:

Correct for directory traverse permission: Directory execute permission permits path traversal or searching entries by name.

C:

This action targets inspect rwx permission bits: The long listing displays the rwx mode string and owner/group columns. The stated task instead calls for directory traverse permission.

D:

This action targets make owner script executable: The symbolic u+x form adds execute permission for the owning user. The stated task instead calls for directory traverse permission.
