Exhibit
openssl verify -CAfile corp-root.pem signed-invoice.pdf signed-invoice.pdf: OK Signature report: - Signer: CN=Northwind Procurement - Issuer: CN=Corp Intermediate CA - Timestamp: 2026-04-14 16:22 UTC - Document digest: matches signature
Based on the exhibit, what is the best conclusion about the signed document?
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
The invoice is confidential because the signature encrypts the document contents.
Digital signatures do not provide confidentiality by themselves. The document may still be readable to anyone who has access to it. The exhibit only shows the signature validated successfully, which speaks to trust and integrity, not secrecy.
B
Best answer
The invoice was not changed after signing and the signer’s certificate chain validated correctly.
A valid digital signature confirms that the document digest still matches the signed value and that the certificate chain was trusted by the verifier. That means the invoice has not been altered since signing, and the signature can be associated with the trusted certificate identity shown in the exhibit.
C
Distractor review
The invoice can be edited if the timestamp is still within business hours.
A timestamp does not grant permission to modify a signed document. If the file were edited, the digest would no longer match the signature. The exhibit explicitly says the digest matches, which supports integrity, not a temporary editing window.
D
Distractor review
The sender’s private key is now public because the certificate verified successfully.
Verifying a certificate does not expose the sender’s private key. The private key remains protected and should never be made public. Successful verification only means the public certificate chain and signature were accepted as valid by the trust store.
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 invoice was not changed after signing and the signer’s certificate chain validated correctly. — The best conclusion is that the invoice was not changed after signing and that the certificate chain validated correctly. The exhibit shows a successful verification result and a matching document digest, which together demonstrate integrity and trust in the signer’s identity. This is exactly what a digital signature is designed to provide: proof that the content has not been altered and that it came from a certificate trusted by the verifier. Why others are wrong: Digital signatures do not encrypt the file, so confidentiality is not guaranteed. The timestamp does not authorize edits, and changing the content would break the signature. A successful verification also does not reveal the private key; only the public certificate is used for validation. The evidence points to integrity and signer authenticity, not secrecy or key exposure.
