Full question →mediummultiple choiceObjective-mapped
After a successful phishing attempt, the security team adds MFA, email sandboxing, endpoint isolation, and immutable backups so that one failed safeguard does not expose the company. Which principle does this best illustrate?
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
Defense in depth
Multiple layered controls are added so that if one control fails, other controls still reduce the risk.
B
Distractor review
Need-to-know
Need-to-know limits access to information, but it does not describe layered control design.
C
Distractor review
Availability
Availability is a security objective, but it is not the specific design principle being demonstrated.
D
Distractor review
Compensating control
Compensating controls replace a missing required control, while this scenario emphasizes many layers together.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Defense in depth — Defense in depth is the best fit because the organization is using several independent safeguards across different layers: user authentication, email inspection, endpoint containment, and backup recovery. The idea is that a single compromise, such as one successful phishing email, should not lead directly to full compromise. Security+ expects you to recognize layered protection as a strategy, not just list individual tools. Why others are wrong: Need-to-know concerns restricting information to only those who require it for their job. Availability is one of the CIA triad objectives, but it is not a layered security strategy. Compensating control refers to an alternative measure used because the preferred control is unavailable or impractical; here the organization is not replacing one missing control, but strengthening multiple defenses at once.
