A cloud administrator is tasked with ensuring that all API requests to the cloud management plane are encrypted. Which protocol should be enforced to meet this requirement?
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
✓
TLS
TLS (Transport Layer Security) encrypts data in transit and is the standard protocol for securing API communications. SSH is for remote shell access, SSL (deprecated) is similar but newer is TLS, and IPsec is used for VPN tunnels.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
TLS
Why this is correct
TLS encrypts HTTP traffic (HTTPS) and is the standard for API security.
- ✗
IPsec
Why it's wrong here
IPsec is used for securing IP communications at the network layer, not typically for API encryption at the application layer.
- ✗
SSL
Why it's wrong here
SSL is the predecessor to TLS and is deprecated; modern systems use TLS.
- ✗
SSH
Why it's wrong here
SSH is used for secure remote administration, not typically for API encryption.
Quick reference
VPN Protocol Comparison
| Protocol | Port | Encryption | Authentication | Use Case |
|---|---|---|---|---|
| IKEv2 / IPsec | UDP 500 / 4500 | AES-256 | Certificates / PSK | Site-to-site & remote access |
| SSL / TLS VPN | TCP 443 | TLS 1.3 | Certificates / MFA | Clientless remote access |
| L2TP / IPsec | UDP 1701 | AES (IPsec) | PSK / Certificates | Legacy remote access |
| WireGuard | UDP 51820 | ChaCha20 | Public keys | Modern high-performance VPN |
| PPTP | TCP 1723 | MPPE (weak) | MS-CHAPv2 | Legacy — avoid in production |
PPTP is considered insecure. IKEv2/IPsec and SSL VPN are the current recommended options.
