A SOC analyst reviews a suspicious email about an overdue invoice. The display name matches a known supplier, but the envelope sender is from a free webmail domain, and the Reply-To address uses a look-alike domain with one swapped letter. The message also includes a company logo and a PDF attachment. Which two findings are the strongest indicators of a phishing attempt? 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.
A
Best answer
The display name matches the supplier, but the envelope sender is from a free webmail provider.
A familiar display name can be copied easily, so it is not trustworthy by itself. An envelope sender using a free webmail provider is inconsistent with a legitimate supplier invoice workflow and strongly suggests impersonation. Attackers often rely on this mismatch to bypass casual review while making the message appear routine.
B
Distractor review
The message was transmitted over TLS to the recipient's mail gateway.
TLS only protects message transport between mail systems. It does not validate the sender's identity, the message content, or the destination links. Phishing campaigns commonly use TLS, so this detail is operationally normal and does not reduce the risk by itself.
C
Best answer
The Reply-To address uses a look-alike domain with one swapped letter in the brand name.
A look-alike domain is a classic phishing indicator because it is designed to catch responses or credential submissions intended for the real vendor. One-character substitutions are particularly effective because they are hard to spot quickly in a busy inbox and often indicate deliberate impersonation rather than a simple typo.
D
Distractor review
The email contains a PDF invoice attachment with a normal business filename.
A PDF attachment and a routine filename are both common in legitimate business communication. While attachments should always be handled carefully, this detail alone does not prove malicious intent. Attackers can use any file type, so the file name is weak evidence compared with sender and domain inconsistencies.
E
Distractor review
The message includes the supplier's logo and a standard-looking signature block.
Logos and signature blocks are easy for attackers to copy from public websites or previous emails. Those elements can make a message look authentic, but they do not verify identity. Security reviewers should treat branding as cosmetic evidence and focus instead on sender, reply-to, and link destination details.
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: The display name matches the supplier, but the envelope sender is from a free webmail provider. — The strongest phishing indicators are the sender identity mismatches. A display name can be spoofed, but a free webmail envelope sender is inconsistent with normal supplier operations. The Reply-To address using a look-alike domain is even more suspicious because it reveals deliberate redirection of responses or credentials. Together, these findings point to impersonation and credential theft rather than a routine invoice notification. Why others are wrong: TLS, a PDF attachment, and a professional-looking signature block do not establish legitimacy. Modern phishing campaigns frequently use encrypted transport, common attachment types, and copied branding to look credible. Those details should be treated as neutral or cosmetic, while domain mismatches and reply-to anomalies are much stronger evidence of malicious intent.
