AZ-400 Develop a security and compliance plan Practice Question
This AZ-400 practice question tests your understanding of develop a security and compliance plan. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
```json
{
"alert": {
"title": "High severity vulnerability found in dependency",
"state": "open",
"severity": "critical",
"created_at": "2026-03-15T10:00:00Z",
"repository": {
"name": "my-app",
"visibility": "internal"
},
"security_advisory": {
"summary": "Remote code execution in lodash",
"severity": "critical",
"cvss": {
"score": 9.8
}
}
}
}
```
You receive a GitHub Dependabot alert as shown. The repository 'my-app' is internal. What is the best immediate action to mitigate the risk?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Update the lodash dependency to the latest patched version
Option A is correct because updating the dependency to a patched version is the best mitigation. Option B is wrong because dismissing the alert ignores the risk. Option C is wrong because creating a private fork does not fix the vulnerability. Option D is wrong because enabling secret scanning does not address dependency vulnerabilities.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Dismiss the alert as it is a false positive
Why it's wrong here
The alert is legitimate and critical.
✗
Create a private fork of the repository
Why it's wrong here
Forking does not fix the vulnerability.
✗
Enable secret scanning on the repository
Why it's wrong here
Secret scanning does not address dependency vulnerabilities.
✓
Update the lodash dependency to the latest patched version
Why this is correct
This directly fixes the vulnerability.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
