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

Confidentiality

Encrypting data during transmission ensures that only authorized parties can read the data, thereby maintaining confidentiality.

B

Distractor review

Integrity

Integrity ensures that data is not tampered with. While encryption can help detect tampering, the primary goal described is preventing unauthorized access, which is confidentiality.

C

Distractor review

Availability

Availability ensures that systems and data are accessible when needed. Encryption does not directly address availability.

D

Distractor review

Non-repudiation

Non-repudiation provides proof of origin and integrity of data, often through digital signatures. It is not the primary goal of encryption during transmission.

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 SC-900 question test?

Standard ACLs match source addresses.

What is the correct answer to this question?

The correct answer is: Confidentiality — The three core security goals are confidentiality, integrity, and availability (CIA triad). Confidentiality ensures that data is not disclosed to unauthorized individuals. Encryption of data in transit prevents eavesdropping, thus protecting confidentiality. While encryption also provides some integrity protection, the scenario explicitly mentions 'protecting from unauthorized access' which is confidentiality. Availability ensures systems are accessible when needed. Non-repudiation is not part of the CIA triad; it ensures that a user cannot deny an action.
