- A
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
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
Decrypt the package with the vendor's private key before installation.
Why wrong: Publicly distributed packages are not normally decrypted this way, and private keys are never shared.
- D
Rotate the organization's internal encryption key before downloading.
Why wrong: Internal key rotation does not verify vendor authenticity or file integrity for the patch package.
- E
Check only the file timestamp and size on disk.
Why wrong: Timestamp and size can change without proving authenticity or detecting malicious tampering.
SY0-701 General Security Concepts Practice Question
This SY0-701 practice question tests your understanding of general security concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Verify the package signature with the vendor's public key.
Option A is correct because verifying the package signature with the vendor's public key confirms the package was cryptographically signed by the vendor, proving its authenticity and integrity. This process uses asymmetric cryptography where the vendor signs the package with their private key, and the security team uses the corresponding public key to validate that signature. It ensures the file was not tampered with after signing and that it originated from the claimed vendor.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse signature verification with encryption/decryption roles, mistakenly thinking the vendor's private key is used to decrypt the package, when in fact the private key is used to sign and the public key to verify.
Detailed technical explanation
How to think about this question
Digital signatures rely on hashing the file content and encrypting that hash with the vendor's private key; verification involves decrypting the signature with the vendor's public key and comparing the resulting hash to a freshly computed hash of the downloaded file. A signed manifest often contains hashes of multiple files, and comparing the downloaded file's hash to the manifest's hash ensures the file matches what the vendor intended. In practice, tools like GPG or Windows Authenticode are used, and the public key must be obtained from a trusted source (e.g., the vendor's website or a certificate authority) to avoid man-in-the-middle attacks.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
