This CCSP practice question tests your understanding of cloud platform and infrastructure security. 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.
An organization is migrating critical workloads to the cloud and must ensure data confidentiality. Which THREE of the following practices help protect data in transit? (Choose three.)
Implementing IPsec VPNs
IPsec encrypts IP packets for site-to-site connectivity.
Using HTTPS for web applications
HTTPS uses TLS to encrypt HTTP traffic.
Applying service control policies (SCPs)
Why wrong: SCPs control service usage, not data encryption.
Enabling server-side encryption (SSE) for data at rest
Why wrong: SSE protects data at rest, not in transit.
Using SSL/TLS for application traffic
TLS encrypts data between client and server.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Implementing IPsec VPNs
IPsec VPNs encrypt IP packets at the network layer, providing end-to-end confidentiality and integrity for all traffic between sites or between a remote user and the cloud. This is a standard practice for securing data in transit across untrusted networks like the internet.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
ISC2 often tests the distinction between data-in-transit controls (like IPsec, TLS, HTTPS) and data-at-rest controls (like SSE) or policy-based controls (like SCPs), leading candidates to mistakenly select options that protect data at rest or manage permissions instead of securing data during transmission.
Detailed technical explanation
IPsec operates in two modes: transport mode (encrypts only the payload) and tunnel mode (encrypts the entire IP packet, adding a new header). In cloud migrations, IPsec is commonly used for site-to-site VPNs between on-premises gateways and cloud virtual private gateways, ensuring all traffic between the two environments is encrypted at Layer 3.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
