300-420 Question 154
Single answerAn organization is planning to connect its on-premises data center to a hybrid cloud solution. The requirements include high availability, predictable performance, and secure connectivity for business-critical applications. Which WAN connectivity option best meets these requirements?
- A
MPLS VPN
- B
Public Internet with IPsec VPN
- C
Dedicated Leased Line
- D
SD-WAN with Public Internet
Show answer and explanation
Correct answer: A
Explanation
MPLS VPN is the most suitable option for this scenario because it offers SLA-backed performance guarantees, high availability, and secure connectivity. These characteristics align with the requirements for connecting an on-premises data center to a hybrid cloud solution, especially for business-critical applications. Other options either lack the necessary performance guarantees or are cost-prohibitive for hybrid cloud environments.
- A. Correct.
MPLS VPN provides high availability, predictable performance through SLA-backed services, and secure connectivity, making it ideal for business-critical applications.
- B. Incorrect.
Public Internet with IPsec VPN is cost-effective but lacks predictable performance and SLA guarantees, making it unsuitable for business-critical applications requiring high availability.
- C. Incorrect.
Dedicated Leased Line offers predictable performance and security but is extremely expensive and less scalable, which may not align with hybrid cloud environments.
- D. Incorrect.
SD-WAN with Public Internet can provide flexibility and cost savings, but it depends on the underlying internet connection, which may not guarantee predictable performance or high availability.
