- A
The package can only be decrypted by the vendor's private key
Why wrong: That describes encryption, not signature verification. The team is not trying to decrypt the file.
- B
The package was likely created by the vendor and was not altered after signing
Digital signature verification checks that the signed data matches what the signer produced and that the signer controlled the corresponding private key. This gives the team confidence in authenticity and integrity. If the file had been modified after signing, verification would fail. That is why signatures are commonly used for software updates and trusted releases.
- C
The package is encrypted with the vendor's public key
Why wrong: Public-key encryption protects confidentiality, but signature verification does not imply the package is encrypted.
- D
The vendor's certificate has not expired
Why wrong: A valid certificate can support signature verification, but the main result of the verification is trust in origin and integrity, not a certificate date check.
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.
A security team downloads a software update package signed by the vendor. The team verifies the signature using the vendor's public key before approving deployment. What does this verification primarily confirm?
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
The package was likely created by the vendor and was not altered after signing
Digital signature verification using the vendor's public key confirms that the package was signed with the vendor's private key, which only the vendor possesses. This provides authentication of the signer's identity and integrity of the data, ensuring the package has not been modified since signing. It does not provide confidentiality, as the package itself is not encrypted.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
The package can only be decrypted by the vendor's private key
Why it's wrong here
That describes encryption, not signature verification. The team is not trying to decrypt the file.
- ✓
The package was likely created by the vendor and was not altered after signing
Why this is correct
Digital signature verification checks that the signed data matches what the signer produced and that the signer controlled the corresponding private key. This gives the team confidence in authenticity and integrity. If the file had been modified after signing, verification would fail. That is why signatures are commonly used for software updates and trusted releases.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing digital signatures with encryption: candidates often think the public key decrypts the package itself, when in fact it only decrypts the hash, and the package remains unencrypted.
Detailed technical explanation
How to think about this question
Digital signatures rely on asymmetric cryptography, typically using RSA or ECDSA. The vendor hashes the package (e.g., with SHA-256) and encrypts that hash with their private key to create the signature. The security team decrypts the signature with the vendor's public key, computes the hash of the downloaded package, and compares the two hashes. If they match, the package is authentic and unaltered. This process is defined in standards like PKCS#1 v2.2 and RFC 8017.
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.
