Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
After a routine dependency update, a development team notices that the customer portal begins making outbound connections to an unfamiliar domain during startup. The domain is not part of the application design, and the behavior started immediately after the third-party library was updated. Which threat is most likely?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Supply-chain compromise
A compromised dependency can introduce malicious behavior through trusted software updates or packages.
B
Distractor review
Evil twin access point
An evil twin is a rogue wireless access point and would not explain unexpected outbound application connections.
C
Distractor review
Bluetooth pairing abuse
Bluetooth abuse targets nearby device pairing and short-range communication, not a web application dependency.
D
Distractor review
DNS poisoning on the client network
DNS poisoning could redirect traffic, but the timing tied to the library update points more directly to the dependency itself.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Supply-chain compromise — This is most consistent with supply-chain compromise, specifically a third-party dependency introducing unexpected behavior after an update. Because the change began immediately after the library was updated, the dependency itself is the likely source rather than a separate network issue. Supply-chain incidents can involve malicious code, tampered packages, or compromised build/release pipelines. In practice, defenders would verify package integrity, review release notes, compare hashes, and isolate the application until the dependency is trusted again. Why others are wrong: An evil twin is a fake wireless network and does not match application startup behavior. Bluetooth pairing abuse is limited to short-range device interactions and is unrelated to software package updates. DNS poisoning may redirect traffic, but it would not by itself explain a direct behavioral change immediately after a library upgrade, which strongly suggests a compromised dependency.
