300-420 Question 155
Select 3An organization is migrating its applications to a hybrid cloud model and wants to ensure reliable WAN connectivity between its on-premises data center and the cloud. The organization also requires low latency and high bandwidth for critical applications. Which WAN connectivity options should the organization consider to meet these requirements?
- A
Dedicated MPLS circuits
- B
Internet VPN connections
- C
Direct cloud interconnect services
- D
Point-to-Point leased lines
- E
Satellite internet connections
Show answer and explanation
Correct answers: A, C, D
Explanation
For hybrid cloud models that require reliable, low-latency, and high-bandwidth connectivity, options like MPLS circuits, direct cloud interconnect services, and Point-to-Point leased lines are ideal. While Internet VPNs and satellite connections may be used in other scenarios, they typically do not meet the performance and reliability requirements for critical applications in a hybrid cloud environment.
- A. Correct.
Dedicated MPLS circuits provide reliable, low-latency, and high-quality connections suitable for hybrid cloud environments.
- B. Incorrect.
Internet VPN connections are cost-effective but often suffer from higher latency and inconsistent performance, which may not meet the requirements.
- C. Correct.
Direct cloud interconnect services, such as AWS Direct Connect or Azure ExpressRoute, are designed for low-latency and high-bandwidth connections to cloud providers and are ideal for hybrid models.
- D. Correct.
Point-to-Point leased lines offer reliable and consistent performance, making them suitable for critical applications that require low latency and high bandwidth.
- E. Incorrect.
Satellite internet connections generally experience high latency and variable bandwidth, making them unsuitable for critical applications or hybrid cloud deployments.
