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.
Exhibit
openssl verify -CAfile corp-root.pem signed-invoice.pdf
signed-invoice.pdf: OK
Signature report:
- Signer: CN=Northwind Procurement
- Issuer: CN=Corp Intermediate CA
- Timestamp: 2026-04-14 16:22 UTC
- Document digest: matches signature
Based on the exhibit, what is the best conclusion about the signed document?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
openssl verify -CAfile corp-root.pem signed-invoice.pdf
signed-invoice.pdf: OK
Signature report:
- Signer: CN=Northwind Procurement
- Issuer: CN=Corp Intermediate CA
- Timestamp: 2026-04-14 16:22 UTC
- Document digest: matches signature
A
The invoice is confidential because the signature encrypts the document contents.
Why wrong: Digital signatures do not provide confidentiality by themselves. The document may still be readable to anyone who has access to it. The exhibit only shows the signature validated successfully, which speaks to trust and integrity, not secrecy.
B
The invoice was not changed after signing and the signer’s certificate chain validated correctly.
A valid digital signature confirms that the document digest still matches the signed value and that the certificate chain was trusted by the verifier. That means the invoice has not been altered since signing, and the signature can be associated with the trusted certificate identity shown in the exhibit.
C
The invoice can be edited if the timestamp is still within business hours.
Why wrong: A timestamp does not grant permission to modify a signed document. If the file were edited, the digest would no longer match the signature. The exhibit explicitly says the digest matches, which supports integrity, not a temporary editing window.
D
The sender’s private key is now public because the certificate verified successfully.
Why wrong: Verifying a certificate does not expose the sender’s private key. The private key remains protected and should never be made public. Successful verification only means the public certificate chain and signature were accepted as valid by the trust store.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The invoice was not changed after signing and the signer’s certificate chain validated correctly.
Option B is correct because a valid digital signature provides both integrity (the document was not altered after signing) and authentication (the signer's certificate chain validates to a trusted root). The exhibit shows a successful signature validation, which cryptographically proves that the invoice has not been modified since signing and that the signing certificate is trusted.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The invoice is confidential because the signature encrypts the document contents.
Why it's wrong here
Digital signatures do not provide confidentiality by themselves. The document may still be readable to anyone who has access to it. The exhibit only shows the signature validated successfully, which speaks to trust and integrity, not secrecy.
✓
The invoice was not changed after signing and the signer’s certificate chain validated correctly.
Why this is correct
A valid digital signature confirms that the document digest still matches the signed value and that the certificate chain was trusted by the verifier. That means the invoice has not been altered since signing, and the signature can be associated with the trusted certificate identity shown in the exhibit.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing digital signatures with encryption — candidates often think signing encrypts the document, but signing only provides integrity and non-repudiation, not confidentiality.
Trap categories for this question
Command / output trap
Digital signatures do not provide confidentiality by themselves. The document may still be readable to anyone who has access to it. The exhibit only shows the signature validated successfully, which speaks to trust and integrity, not secrecy.
Detailed technical explanation
How to think about this question
Digital signatures use asymmetric cryptography: the signer creates a hash of the document (e.g., SHA-256) and encrypts that hash with their private key. The verifier decrypts the hash with the public key from the certificate and compares it to a freshly computed hash; any mismatch indicates tampering. The certificate chain validation ensures the signing certificate is issued by a trusted Certificate Authority (CA) and has not been revoked, typically checked via CRL or OCSP.

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.

What is the correct answer to this question?
The correct answer is: The invoice was not changed after signing and the signer’s certificate chain validated correctly. — Option B is correct because a valid digital signature provides both integrity (the document was not altered after signing) and authentication (the signer's certificate chain validates to a trusted root). The exhibit shows a successful signature validation, which cryptographically proves that the invoice has not been modified since signing and that the signing certificate is trusted.
