SC-200 Respond to security incidents Practice Question

This SC-200 practice question tests your understanding of respond to security incidents. 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.

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

✓

Blocks traffic originating from IP address 10.0.0.1.

The JSON snippet defines a WAF rule with a match condition that checks if the client IP address equals 10.0.0.1. The action is set to 'Block', meaning any request from that specific IP address will be denied. Option B correctly identifies this behavior.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

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

  • ✗

    Blocks traffic from the entire 10.0.0.0/24 subnet.

    Why it's wrong here

    The match value is a single IP, not a subnet.

  • ✓

    Blocks traffic originating from IP address 10.0.0.1.

    Why this is correct

    The rule matches RemoteAddr with IPMatch operator for '10.0.0.1' and blocks it.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Logs traffic from IP address 10.0.0.1 without blocking.

    Why it's wrong here

    The action is 'Block', not 'Log'.

  • ✗

    Allows traffic from IP address 10.0.0.1.

    Why it's wrong here

    The action type is 'Block', not 'Allow'.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse an exact IP match with a subnet match, assuming '10.0.0.1' implies the entire /24 range, or they misread the 'Block' action as 'Allow' or 'Log' due to familiarity with other WAF rule types.

Detailed technical explanation

How to think about this question

Azure WAF rules use a priority-based evaluation where each rule can match on attributes like source IP, URI, or headers. The 'matchVariable' 'RemoteAddr' refers to the client's IP address as seen by the WAF, and the 'operator' 'IPMatch' performs an exact string comparison (not CIDR). In real-world scenarios, this is used to block specific malicious IPs without affecting other traffic from the same subnet, which is common when dealing with targeted attacks or botnets.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
