Before installing a vendor patch package on hundreds of endpoints, the security team wants to confirm the file was published by the vendor and was not altered during download. Which two verification steps should the team perform? 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
Verify the package signature with the vendor's public key.
A valid signature proves the package came from the holder of the vendor's private key.
B
Best answer
Compare the downloaded package hash to the hash in the signed manifest.
Matching hashes confirms the downloaded file has not been altered in transit.
C
Distractor review
Decrypt the package with the vendor's private key before installation.
Publicly distributed packages are not normally decrypted this way, and private keys are never shared.
D
Distractor review
Rotate the organization's internal encryption key before downloading.
Internal key rotation does not verify vendor authenticity or file integrity for the patch package.
E
Distractor review
Check only the file timestamp and size on disk.
Timestamp and size can change without proving authenticity or detecting malicious tampering.
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: Verify the package signature with the vendor's public key. — The team should verify the digital signature using the vendor's public key and compare the downloaded package hash against the hash in the signed manifest. The signature proves the file was released by the vendor, while the hash comparison confirms the file was not modified after publication or during transfer. Using both checks provides authenticity and integrity, which is the right security posture before mass deployment of a patch. Why others are wrong: Decrypting with the vendor's private key is not how signed update validation works, and private keys should never be exposed. Internal key rotation is unrelated to verifying an external vendor package. File timestamps and size are weak indicators and do not protect against substitution, tampering, or malicious repackaging of an update file.
