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.)

https://docs.oracle.com/en-us/iaas/Content/Network/Concepts/fastconnectoverview.htmBased on the requirements provided, the best solution would be to provision FastConnect with a single private virtual circuit, and run an IPsec VPN tunnel over the top of this virtual circuit. Here's why:
Low latency: FastConnect provides a dedicated, private connection between your on-premises network and OCI, resulting in lower latency than using a VPN over the public internet.
Consistency: Since the connection is dedicated, there is less chance of performance variation compared to using a VPN over the public internet.
Performance: FastConnect can support up to 100 Gbps, so a 1.25 Gbps connection is easily achievable.
Encryption: FastConnect provides the option to use private virtual circuits, which can be configured with encryption, ensuring that any data in transit between your on-premises network and the VCN is secure.
Low cost: FastConnect pricing is based on the speed of the connection and is generally lower than using a VPN over the public internet.
Option A is the best choice because it meets all the requirements of the client at the lowest possible cost. It provides a private, high-bandwidth, low-latency, and secure connection between the on-premises network and the VCN. The IPsec VPN tunnel provides an additional layer of encryption to ensure data security in transit.
Option B is not recommended because it does not provide a private connection, and the latency and performance may be affected by other traffic on the public internet.
Option C provides a secure connection through VPN Connect but is not recommended due to the lower performance and potential for inconsistent performance compared to FastConnect.
Option D provides a private connection but lacks the additional layer of encryption provided by the IPsec VPN tunnel.
Option E provides a public connection with an IPsec VPN tunnel, but it is not recommended due to the potential for inconsistent performance over the public internet.
