SSCP Systems and Application Security Practice Question
This SSCP practice question tests your understanding of systems and application security. 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.
A company deploys a web application that processes credit card payments. The development team uses parameterized queries for all database interactions. However, during a penetration test, the tester successfully injects malicious code into a search field and retrieves sensitive customer data. Which of the following is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The application uses dynamic SQL despite parameterized queries for some fields.
Option A is correct because the use of parameterized queries prevents SQL injection, but if dynamic SQL is constructed elsewhere in the application (e.g., for the search field), it can still be vulnerable. Option B is incorrect because XSS affects client-side execution, not direct data retrieval from the database. Option C is incorrect because direct query execution would require explicit permissions beyond the application's context. Option D is incorrect because directory traversal exploits file system access, not database query injection.
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.
✓
The application uses dynamic SQL despite parameterized queries for some fields.
Why this is correct
Dynamic SQL in the search field bypasses the parameterized queries used elsewhere, allowing injection.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The web server is misconfigured to allow directory traversal.
Why it's wrong here
Directory traversal accesses files, not database content.
✗
The database server has weak permissions allowing direct query execution.
Why it's wrong here
Weak permissions could allow unauthorized queries, but the injection occurred through the application.
✗
The search field output is not sanitized, allowing stored XSS.
Why it's wrong here
Stored XSS would execute in users' browsers, not directly retrieve database data.
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 developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
