Prevent Password Sharing: Use Group Permissions

This 220-1202 practice question tests your understanding of logical security concepts. 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.

A technician discovers that a user has been sharing their login credentials with coworkers to allow them to access a shared drive. The company's security policy prohibits password sharing. What is the most effective way to prevent this behavior while still allowing necessary access?

Quick Answer

The answer is to configure the shared drive permissions using security groups and add the coworkers to the appropriate group. This is correct because the root cause of password sharing is that access is tied to individual accounts, which forces users to share credentials when coworkers need the same resource. By implementing group-based permissions with proper access control lists (ACLs), you grant access to a group rather than an individual, eliminating the need to share passwords while maintaining necessary access. On the CompTIA A+ Core 2 220-1202 exam, this tests your understanding of access control models and the principle of least privilege—a common trap is to choose user training or password complexity policies, but those don’t address the structural flaw. Remember the memory tip: “Groups grant, passwords protect”—always assign permissions to groups, not people, to prevent sharing.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Configure the shared drive permissions using security groups and add the coworkers to the appropriate group.

The root cause is that the shared drive access is tied to individual accounts, encouraging sharing. Implementing group-based permissions with proper access control lists (ACLs) allows the company to grant access to a group rather than an individual, eliminating the need to share passwords. Additionally, enforcing a policy of non-repudiation and using audit logs can deter sharing.

Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Disable the user's account and create a generic shared account for the drive.

    Why it's wrong here

    Generic accounts violate security principles and make auditing impossible; they encourage further misuse.

  • Implement a Group Policy that forces password changes every 30 days.

    Why it's wrong here

    Frequent password changes may reduce sharing but do not address the underlying need for shared access.

  • Configure the shared drive permissions using security groups and add the coworkers to the appropriate group.

    Why this is correct

    This grants necessary access without sharing passwords, enforcing least privilege and accountability.

    Related concept

    Standard ACLs match source addresses.

  • Send a company-wide email reminding users not to share passwords.

    Why it's wrong here

    Education is important but often insufficient to stop the behavior without technical controls.

Common exam traps

Common exam trap: ACLs stop at the first match

ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.

Detailed technical explanation

How to think about this question

ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.

KKey Concepts to Remember

  • Standard ACLs match source addresses.
  • Extended ACLs can match source, destination, protocol and ports.
  • The first matching ACL entry is used.
  • There is usually an implicit deny at the end.

TExam Day Tips

  • Check inbound versus outbound direction.
  • Read the ACL from top to bottom.
  • Look for a broader permit or deny above the intended line.

Key takeaway

ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Real-world example

How this comes up in practice

A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.

Visual reference

Source Router + ACL permit 10.0.0.0/8 deny any Server 10.0.0.5 ✓ 192.168.1.1 ✗ dropped ACLs evaluate top-down; first match wins — implicit deny all at end

What to study next

Got this wrong? Here's your next step.

Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related 220-1202 ACL questions on filtering logic and placement.
