Question 914 of 1,152

Security Architecture →hardMultiple SelectObjective-mapped

Quick Answer

The answer is to use HTTPS with a trusted certificate authority (CA) and to digitally sign the update packages. HTTPS provides server identity validation by allowing the client to verify the certificate’s chain of trust and domain match, which prevents man-in-the-middle attacks during the initial connection. Digital signatures ensure update integrity because the signature is created with a private key and verified with a public key, so even if the web server is later compromised, the signed packages remain tamper-proof. On the Security+ SY0-701 exam, this question tests your understanding of defense-in-depth: HTTPS secures the channel, while digital signatures protect the content beyond the channel. A common trap is to think HTTPS alone guarantees package integrity, but it only protects data in transit—once the server is compromised, unsigned updates could be swapped. Memory tip: HTTPS for the handshake, digital signatures for the payload—trust the channel, then trust the file.

SY0-701 Security Architecture Practice Question

This SY0-701 practice question tests your understanding of security architecture. 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 company distributes update packages through a web portal. Users must verify the portal's identity over the network, and the downloaded packages must be trusted even if the web server is later compromised. Which two controls best satisfy these goals? Select two.

A
Use HTTPS with a certificate from a trusted certificate authority so users can validate the portal.
HTTPS protects the connection in transit and lets clients validate that they are communicating with the expected portal through trusted certificate chains. That addresses the need to confirm the portal's identity over the network and prevents interception or modification by an attacker on the path.
B
Use FTP over the internet because the credentialed login keeps the transfer secure enough.
Why wrong: FTP does not provide encryption or strong server identity validation for the data path. Credentials alone do not make the traffic confidential or resistant to interception. Because the scenario requires identity verification and trust in transit, FTP is not an acceptable choice.
C
Digitally sign the update packages so clients can verify integrity even if the web server is later compromised.
Digital signatures let clients verify that the package was created by a trusted publisher and has not changed since it was signed. Even if the web server is compromised, attackers cannot forge a valid signature without the private key. This protects the authenticity and integrity of the update itself.
D
Publish a SHA-256 hash on the same download page and trust that the server will remain honest.
Why wrong: A hash posted on the same server is only useful if the server is trustworthy at the moment the user checks it. If the web server is compromised, an attacker can replace both the file and the hash. A standalone hash does not provide the same tamper resistance as a digital signature.
E
Use plain HTTP and rely on file permissions to protect the updates in transit.
Why wrong: File permissions protect storage on the server, not the network path between the server and the user. Plain HTTP offers no confidentiality or identity validation, so an attacker could modify or intercept the package. The scenario specifically requires secure transmission and trust even if the server is later compromised.

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

✓

Use HTTPS with a certificate from a trusted certificate authority so users can validate the portal.

HTTPS with a certificate from a trusted certificate authority (CA) allows the client to validate the web portal's identity by verifying the certificate's chain of trust and ensuring the domain name matches. This prevents man-in-the-middle attacks and confirms the server is legitimate before any data is exchanged.

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 may think FTP with credentials is sufficient for identity verification, but FTP does not provide certificate-based server authentication, and the question specifically requires verifying the portal's identity over the network, which only HTTPS with a trusted CA certificate achieves.

Trap categories for this question

Scenario analysis trap
FTP does not provide encryption or strong server identity validation for the data path. Credentials alone do not make the traffic confidential or resistant to interception. Because the scenario requires identity verification and trust in transit, FTP is not an acceptable choice.

Detailed technical explanation

How to think about this question

HTTPS uses TLS to encrypt the session, and the server presents an X.509 certificate signed by a trusted CA. The client performs certificate path validation, checks the signature, expiration, and revocation status (via CRL or OCSP) to confirm the server's identity. Digitally signing update packages with a private key (e.g., using RSA or ECDSA) allows clients to verify the signature with the corresponding public key, ensuring integrity and authenticity even if the server is later compromised, because the signature is generated offline and cannot be forged without the private key.

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.
