Oracle Cloud Infrastructure 2021 Multicloud Architect Associate — Question 28

You have been asked to set up connectivity between a client's on-premises network and Oracle Cloud Infrastructure (OCI). The requirements are:
✑ Low latency: The applications are financial and require low latency connectivity into OCI.
✑ Consistency: The application isn't tolerant of performance variation.
✑ Performance: The communications link needs to support up to 1.25 Gbps.
✑ Encryption: The communications link needs to encrypt any data in transit between the on-premises network and OCI Virtual Cloud Network (VCN).
The client wants to implement the above with as low a cost as possible, while meeting all of the requirements. What should you suggest? (Choose the best answer.)

Answer options

• A. Provision FastConnect with a single private virtual circuit, and run an IPsec VPN tunnel over the top of this virtual circuit.
• B. Provision FastConnect with a single public virtual circuit.
• C. Provision a site-to-site IPsec VPN between your on-premises network and your virtual cloud network (VCN) using VPN Connect.
• D. Provision FastConnect with a single private virtual circuit.
• E. Provision FastConnect with a single public virtual circuit, and run an IPsec VPN tunnel over the top of this virtual circuit.

Correct answer: E

Explanation

Option E is the best choice because it provides low latency and high bandwidth through FastConnect while ensuring data encryption via the IPsec VPN tunnel, addressing all requirements effectively. Options A and D do not meet the requirement for a public virtual circuit, while option B does not provide the necessary encryption for data in transit, making them unsuitable. Option C lacks the dedicated bandwidth of FastConnect, which is essential for the client's financial applications.
