CV0-004 Practice Question: A hybrid cloud deployment connects an on-premises…
A hybrid cloud deployment connects an on-premises data center to a public cloud. Which TWO components are typically required to establish this connectivity? (Select TWO.)
⚠ Common exam trap
It's easy for candidates to confuse application-layer components (like load balancers or DNS) with network-layer connectivity components, or mistakenly think that public internet with HTTPS alone is sufficient for site-to-site hybrid cloud connectivity.
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
✓
Direct peering or dedicated connection (e.g., AWS Direct Connect)
A dedicated connection like AWS Direct Connect provides a private, high-bandwidth, low-latency link between an on-premises data center and a public cloud, bypassing the public internet for consistent performance and security. Option C is correct because a VPN gateway establishes an encrypted tunnel over the public internet (using protocols like IPsec) to securely connect the on-premises network to the cloud VPC, which is a standard requirement for hybrid cloud connectivity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Load balancer in the cloud
Why it's wrong here
Load balancers distribute traffic within the cloud, not connect on-premises to cloud.
- ✓
Direct peering or dedicated connection (e.g., AWS Direct Connect)
Why this is correct
Direct connection provides a private, high-bandwidth link between on-premises and cloud.
- ✓
Virtual private network (VPN) gateway
Why this is correct
VPN gateway provides encrypted connectivity over the internet.
- ✗
Public internet with HTTPS
Why it's wrong here
HTTPS alone does not establish a secure network link for hybrid cloud connectivity.
- ✗
Cloud-based DNS resolver
Why it's wrong here
DNS is for name resolution, not connectivity between environments.
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.
