- A
Configure adaptive application controls to whitelist allowed applications
Why wrong: Adaptive application controls are for controlling which applications can run, not for detecting brute-force attacks.
- B
Enable vulnerability assessment and review the findings
Why wrong: Vulnerability assessment identifies known CVEs but does not help verify a brute-force attack in real time.
- C
Enable Just-in-Time (JIT) VM access for the affected VM
JIT blocks unauthorized access attempts by restricting inbound traffic to specific IPs and ports, preventing brute-force attacks.
- D
Enable Azure DDoS Protection on the virtual network
Why wrong: DDoS Protection is for volumetric attacks, not brute-force attacks on a single VM.
- E
Use File Integrity Monitoring (FIM) to check for changes to system files
FIM monitors and alerts on changes to critical files, which can indicate a successful compromise.
Quick Answer
The correct answer is to use Just-in-Time (JIT) VM access and File Integrity Monitoring (FIM) together. JIT VM access immediately blocks ongoing brute-force attempts by restricting inbound traffic to only authorized IPs and ports, effectively locking out the attacker. FIM then verifies whether the attack succeeded by checking for unauthorized changes to critical system files, such as /etc/passwd or SSH configurations, which indicate a compromise. On the AZ-500 exam, this pairing tests your understanding of combining preventive and detective controls for a complete incident response workflow. A common trap is choosing vulnerability assessment or DDoS protection, which address different threats. Remember the memory tip: “JIT blocks the knock, FIM checks the lock”—JIT stops the brute-force at the network layer, while FIM confirms if the system was breached.
AZ-500 Practice Question: Secure Azure using Microsoft Defender for Cloud and Microsoft Sentinel
This AZ-500 practice question tests your understanding of secure azure using microsoft defender for cloud and microsoft sentinel. 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.
Your company uses Microsoft Defender for Cloud to secure its Azure resources. The security team receives alerts about a potential brute-force attack on a Linux virtual machine. You need to verify whether the attack was successful and take immediate remediation actions. Which two Defender for Cloud features should you use together?
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
Enable Just-in-Time (JIT) VM access for the affected VM
Option B is correct because Just-in-Time VM access can block brute-force attempts by allowing only authorized IPs and ports. Option C is correct because the File Integrity Monitoring (FIM) feature can detect changes to critical system files, indicating a successful compromise. Option A is wrong because vulnerability assessment is for checking known vulnerabilities, not real-time attack verification. Option D is wrong because adaptive application controls whitelist applications, not directly related to brute-force detection. Option E is wrong because Azure DDoS Protection is for network-level DDoS, not brute-force attacks.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
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.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
