This EX200 practice question tests your understanding of manage users and groups. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Refer to the exhibit. A user bob exists with UID 1002 and GID 1002. The /etc/group shows a group bob with GID 1002 but no members listed. Bob tries to access a file owned by group 'bob' with permissions 640 and owner root. What will happen?
Bob will not be able to read the file because the group bob has no members.
Why wrong: Option B is incorrect; primary group membership does not require explicit listing in /etc/group.
B
Bob will be able to read the file because he is a member of the group bob.
Why wrong: Option A is partially correct but misleading; the reason is his primary group membership, not explicit listing.
C
Bob will be able to read the file if his primary group is bob, which it is.
Option C is correct; Bob's primary group is bob (GID 1002) as defined in /etc/passwd, so he is considered a member of the group bob for file access purposes.
D
Bob will be able to read the file only if he is explicitly listed in /etc/group.
Why wrong: Option D is incorrect; explicit listing is only needed for supplementary group membership.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

Real-world example
How this comes up in practice
A practitioner preparing for the EX200 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
