Full question →mediummultiple choiceObjective-mapped
A legal team must send a confidential contract to a partner so only the intended recipient can read it, and the partner also needs assurance the file really came from your company. Which approach best meets both needs?
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
Hash the contract and email the hash value separately.
A hash can help detect tampering, but it does not provide confidentiality or prove authorship by itself.
B
Best answer
Encrypt the file with the recipient's public key and sign it with the sender's private key.
Using the recipient's public key ensures only the intended recipient can decrypt the file, which provides confidentiality. Adding a digital signature with the sender's private key gives the partner a way to verify the file came from your company and has not been altered. Together, these controls address both privacy and authenticity, which is exactly what the scenario requires.
C
Distractor review
Use a shared symmetric key and send the key in the same email message.
A shared key can encrypt data, but sending it in the same message defeats the protection and creates obvious exposure.
D
Distractor review
Compress the file and password-protect the archive with a simple passphrase.
Password protection is weaker than proper public key encryption and does not provide strong, verifiable origin assurance.
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: Encrypt the file with the recipient's public key and sign it with the sender's private key. — The best answer combines confidentiality and authenticity. Encrypting with the recipient's public key means only that recipient can open the contract, while a digital signature from the sender's private key proves who created it and lets the recipient detect changes. This pairing is a common secure-file workflow when sensitive material must cross organizational boundaries and trust in the sender matters as much as secrecy. Why others are wrong: A hash only shows whether the content changed; it does not hide the file or identify the sender. A symmetric key can protect content, but sharing that key insecurely undermines the whole design. Password-protected archives are convenient but are not the best answer when stronger cryptographic controls are available. The scenario needs both confidentiality and sender verification, so public-key encryption plus signing is superior.
