200-201 Security Policies and Procedures Practice Question

This 200-201 practice question tests your understanding of security policies and procedures. 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.

Exhibit

Refer to the exhibit.
ip access-list extended BLOCK_CRITICAL
 deny tcp any any eq 3389
 deny tcp any any eq 23
 permit ip any any

Refer to the exhibit. A security policy states that all remote desktop (RDP) and Telnet access from external networks must be blocked. Does the above access-list comply with the policy?

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

Yes, because it denies RDP and Telnet.

The ACL explicitly denies RDP (port 3389) and Telnet (port 23) and permits all other traffic, which fully meets the policy requirement. The policy does not require blocking other services.

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.

  • Yes, because it denies RDP and Telnet.

    Why this is correct

    The ACL denies both services required by policy.

    Related concept

    Standard ACLs match source addresses.

  • Yes, because it denies TCP ports 3389 and 23.

    Why it's wrong here

    This is also true but option A is more concise; however, only one correct answer. A is the best.

  • No, because it permits all other traffic.

    Why it's wrong here

    The policy only requires blocking those two services; permitting other traffic is acceptable.

  • No, because it should deny HTTP traffic as well.

    Why it's wrong here

    HTTP is not mentioned in the policy.

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.

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 200-201 ACL questions on filtering logic and placement.
