Full question →mediummultiple choiceObjective-mapped
A legal department needs a contract file that can later prove who signed it and whether the content changed after signing. Which cryptographic mechanism should be used?
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
Hashing
Hashing can detect changes, but it cannot bind the document to a specific signer.
B
Distractor review
Tokenization
Tokenization replaces data values, which is useful for privacy but not for signature validation.
C
Best answer
Digital signature
Digital signatures provide tamper detection and signer validation using asymmetric cryptography.
D
Distractor review
Symmetric encryption
Symmetric encryption hides content but does not identify the signer or prove document integrity alone.
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: Digital signature — A digital signature is the best choice because it combines integrity checking with proof of the signer’s identity, assuming the certificate chain is trusted. The signer uses a private key to create the signature, and others verify it with the matching public key. This lets the legal department detect tampering and later demonstrate that a particular key holder approved the document. Why others are wrong: Symmetric encryption protects confidentiality but does not, by itself, prove who signed the file or whether the file changed. Hashing detects change but does not bind that change detection to a person or organization. Tokenization substitutes values with tokens and is mainly used to reduce exposure of sensitive data, not to establish signer identity or nonrepudiation.
