CompTIA Project+ (PK0-005)Basics of IT and GovernanceHard
An organization is migrating its data center to a hybrid cloud model, integrating existing on-premises infrastructure with public cloud services. The project manager needs to ensure seamless and secure communication between the on-premises network and the cloud environment. Which technology is crucial for establishing this type of dedicated, private network connection?
- AVirtual Private Network (VPN)
- BWireless Local Area Network (WLAN)
- CDirect Connect / ExpressRoute (Private Interconnect)
- DInternet Service Provider (ISP) connection
Show answer & explanationAnswer & explanation
Correct answer: C. Direct Connect / ExpressRoute (Private Interconnect)
Dedicated private interconnect services like AWS Direct Connect or Azure ExpressRoute provide a direct, private network connection from a customer's premises to a cloud provider, offering higher bandwidth, lower latency, and enhanced security compared to internet-based VPNs.
Why the other options are wrong
- A. VPNs provide secure connections over the public internet, which may not offer the 'dedicated' and 'private' performance guarantees needed for robust hybrid cloud integration.
- B. WLANs are for local wireless connectivity and are irrelevant for connecting geographically separate data centers and cloud environments.
- D. An ISP connection is a general internet connection and lacks the dedicated, private nature required for seamless and secure hybrid cloud integration.
Cloud Private Interconnect
A dedicated, private network connection that links an organization's on-premises infrastructure directly to a public cloud provider's network, bypassing the public internet. Examples include AWS Direct Connect and Azure ExpressRoute.
- Provides dedicated, high-bandwidth connectivity.
- Offers lower latency and consistent network performance.
- Enhances security by not traversing the public internet.
Memory trick: Private Connect: Direct, Dedicated, Dependable.
