CompTIA Cloud Essentials+ (CLO-002)Cloud ConceptsMedium
A cloud customer is experiencing inconsistent network performance when accessing their cloud-hosted applications from their on-premises data center. They use a standard internet VPN connection. The CIO is concerned about data transfer costs and potential security risks over the public internet. What networking solution would BEST address these concerns?
- AImplement direct cloud connectivity
- BOptimize DNS resolution
- CIncrease VPN bandwidth
- DDeploy a cloud-based firewall
Show answer & explanationAnswer & explanation
Correct answer: A. Implement direct cloud connectivity
Direct cloud connectivity establishes a dedicated, private network connection between the customer's on-premises data center and the cloud provider, bypassing the public internet. This significantly improves performance, reduces latency, enhances security, and often lowers data transfer costs compared to VPNs over the public internet.
Why the other options are wrong
- B. Optimizing DNS resolution might slightly improve initial connection times but won't address sustained performance, security, or cost issues of data transfer.
- C. Increasing VPN bandwidth might help performance but doesn't address the inherent security and cost concerns of routing over the public internet.
- D. A cloud-based firewall enhances security within the cloud environment but doesn't resolve performance, cost, or security issues of the connection from on-premises over the public internet.
Direct Cloud Connectivity
A dedicated, private network connection established between a customer's on-premises infrastructure and a cloud provider's network, bypassing the public internet.
- Provides consistent, higher bandwidth and lower latency.
- Enhances security by avoiding the public internet.
- Can reduce data transfer costs for high volumes.
