An email security team receives a macro-enabled spreadsheet from a known supplier. The file must be analyzed before users open it, and if it proves malicious, the organization wants to stop the same attachment from reaching other inboxes. Which two tools are the best fit? Select two.
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.
Best answer
Sandboxing the attachment in an isolated environment.
Sandboxing safely detonates the file so analysts can observe behavior without risking an endpoint or user workstation.
Best answer
Using a secure email gateway with attachment detonation and quarantine.
An email gateway can inspect the message, detonate the attachment, and quarantine it before broader delivery occurs.
Distractor review
Network access control to verify the supplier's laptop posture.
NAC controls device access to the network, which does not analyze an email attachment or stop delivery to inboxes.
Distractor review
Data loss prevention to block outbound customer records.
DLP focuses on detecting sensitive data leaving the organization, not on safely detonating suspicious spreadsheet attachments.
Distractor review
Intrusion detection system signatures on the mail server.
IDS may detect some malicious traffic patterns, but it does not safely execute the file or quarantine the email itself.
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: Sandboxing the attachment in an isolated environment. — Sandboxing lets the team open the attachment in isolation and see whether it drops files, launches processes, or calls out to external systems. A secure email gateway with detonation and quarantine then prevents the same message from reaching additional users while the analysis is underway. Together, these tools support safe inspection and broad containment before a suspicious attachment can spread. Why others are wrong: NAC governs endpoint access, not attachment analysis. DLP is for sensitive data leakage, not malicious file behavior. An IDS can spot some network indicators, but it does not execute the file or quarantine the email for the rest of the organization.
