Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A finance application stores approval records for wire transfers. Auditors need to prove which employee approved each transfer, and employees must not be able to deny their approval later. Which security objective is best addressed by binding each approval to an individual identity and preserving immutable logs?
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
Distractor review
Confidentiality, because the approval records should be hidden from everyone except finance staff.
Incorrect. Confidentiality protects data from unauthorized viewing, but it does not prove who approved an action or prevent denial later.
B
Best answer
Nonrepudiation, because the organization needs proof that a specific person performed the approval.
Correct. Nonrepudiation provides evidence that a specific user performed an action and later cannot reasonably deny it. Binding approvals to individual identities, using signed records, and keeping immutable logs all support that objective. This is especially important for financial workflows where auditors must trace accountability for every approval.
C
Distractor review
Availability, because the approval system must remain online during business hours.
Incorrect. Availability ensures systems and data are accessible when needed, but it does not establish proof of who approved a transaction.
D
Distractor review
Integrity, because the record must never be changed after it is saved.
Incorrect. Integrity helps prevent unauthorized alteration of records, but it does not by itself prove which person performed the approval.
Common exam trap
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Technical deep dive
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Standard ACLs match source addresses.
What is the correct answer to this question?
The correct answer is: Nonrepudiation, because the organization needs proof that a specific person performed the approval. — Nonrepudiation is the best fit because the business problem is not simply protecting the record from being read or modified. The requirement is to prove that a specific employee approved a transfer and to prevent later denial. Using unique user identities, signed approvals, and tamper-evident logs creates evidence that supports attribution and accountability during audits and disputes. Why others are wrong: Confidentiality focuses on secrecy, not proof of action. Availability matters when systems must stay online, but it does not establish user attribution. Integrity protects records from unauthorized change, yet a record can be intact and still not prove who created it. The scenario is specifically about demonstrating responsibility for the approval.
