SCS-C02 Data Protection Practice Question
A company is migrating on-premises data to AWS using AWS Snowball Edge. The data must be encrypted in transit and at rest. Which combination of steps should be taken?
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 Snowball Edge with default encryption settings; data is encrypted at rest and in transit.
Snowball Edge automatically encrypts data at rest using AES-256 and uses TLS for data in transit. Option A is incorrect because client-side encryption is not required; Snowball Edge handles encryption automatically. Option B is incorrect because Snowball Edge transfers data via its own secure protocol, not VPN. Option C is incorrect because KMS is not directly used for Snowball encryption; the device manages its own encryption keys.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Encrypt the data with a client-side tool before copying to Snowball Edge.
Why it's wrong here
Client-side encryption is not required; Snowball Edge encrypts data automatically.
- ✗
Set up a VPN connection to AWS and transfer data over the VPN.
Why it's wrong here
A VPN connection is not used with Snowball Edge; the device uses its own secure transfer method.
- ✗
Use AWS KMS to generate a key and apply it to the Snowball Edge device.
Why it's wrong here
AWS KMS is not directly applied to Snowball Edge devices; the device generates and manages its own encryption keys.
- ✓
Use Snowball Edge with default encryption settings; data is encrypted at rest and in transit.
Why this is correct
Correct. Snowball Edge encrypts data at rest with AES-256 and in transit with TLS.
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.
