CompTIA Cloud Essentials+ (CLO-002)Cloud ConceptsEasy
A company is evaluating cloud providers and comparing their networking capabilities. They need to ensure that their applications can communicate with other services within the same cloud region using high-bandwidth, low-latency connections. Which of the following networking concepts is crucial for this requirement?
- ADirect Connect
- BVirtual Private Network (VPN)
- CVirtual Private Cloud (VPC)
- DContent Delivery Network (CDN)
Show answer & explanationAnswer & explanation
Correct answer: C. Virtual Private Cloud (VPC)
A Virtual Private Cloud (VPC) provides an isolated section of the cloud where users can launch resources in a virtual network they define. This allows applications within the same VPC (and thus typically the same region) to communicate with high-bandwidth and low-latency internal connections.
Why the other options are wrong
- A. Direct Connect provides a dedicated physical connection between on-premises infrastructure and the cloud provider, not for internal cloud communication.
- B. VPNs are primarily for secure connections over the public internet, typically between on-premises and cloud, not for high-bandwidth, low-latency communication within a cloud region.
- D. CDNs are used to distribute content globally for faster delivery to end-users, not for internal application communication within a cloud region.
Virtual Private Cloud (VPC)
A logically isolated section of a public cloud where users can launch cloud resources in a virtual network that they define, offering control over network configuration, IP addressing, and security.
- Isolated network within a public cloud.
- User-defined IP address ranges, subnets, route tables.
- Enables secure and private internal communication.
Memory trick: VPNs CDN VPC DIRECTS traffic.
