1Z0-1151-25 Question 7
Single answerYour e-commerce company plans to migrate some critical workloads to Oracle Cloud Infrastructure (OCI) while retaining others on a different cloud provider to optimize costs and performance. You need to ensure low latency and secure connectivity for high-volume data transfers between OCI and the other cloud. Which option is the most appropriate first step to establish a secure and high-performance multicloud environment?
- A
Open all traffic from the external internet for both clouds to allow unrestricted data exchange
- B
Create private connectivity using dedicated interconnects (e.g., OCI FastConnect and equivalent on the other cloud)
- C
Rely solely on the public internet via SSL encryption to protect data in transit
- D
Implement only secure shell (SSH) tunneling for all application communication between the two clouds
Show answer and explanation
Correct answer: B
Explanation
Establishing a private, dedicated network path (e.g., OCI FastConnect) is recommended for secure, high-performance connectivity in a multicloud setup. Public internet paths alone can introduce latency, bandwidth limitations, and security concerns, especially when dealing with enterprise-scale workloads. Refer to Oracle's documentation on FastConnect (https://docs.oracle.com/en-us/iaas/Content/Network/Concepts/fastconnect.htm) and the other cloud provider� dedicated connectivity services for best practices on multicloud networking.
- A. Incorrect.
Option 1: Opening all ports and allowing unrestricted internet traffic introduces significant security risks and does not guarantee low latency. This approach is neither recommended nor compliant with security best practices.
- B. Correct.
Option 2: Establishing private connectivity through dedicated interconnects (like OCI FastConnect and the other cloud� equivalent service) sets up a secure, high-bandwidth, and low-latency link between the clouds. This is the best practice for multicloud environments requiring reliable performance and security.
- C. Incorrect.
Option 3: While SSL/TLS encryption can secure data in transit, relying solely on the public internet for high-throughput or latency-sensitive applications often leads to unpredictable performance and potential bottlenecks.
- D. Incorrect.
Option 4: SSH tunneling can be a useful tool for specific administrative tasks or limited data transfers, but it is not practical or scalable for an entire production environment that handles high-volume traffic between clouds.
