1Z0-997-25 Question 119
Select 2Your organization is designing a data analytics solution that combines data from a microservices-based application running in AWS with an Autonomous Database in Oracle Cloud Infrastructure (OCI). The team needs secure, low-latency connectivity between both clouds while minimizing data egress costs. Which two approaches should you include in your design? (Choose two.)
- A
Deploy a new Oracle Database instance directly in AWS to avoid network egress altogether
- B
Establish a dedicated private connection between AWS and OCI through AWS Direct Connect and OCI FastConnect
- C
Route all application traffic over the public internet with built-in encryption in transit
- D
Route cross-cloud traffic through your on-premises environment by setting up VPN connections between each cloud and on-premises
Show answer and explanation
Correct answers: B, D
Explanation
When evaluating multi-cloud solution architectures between AWS and Oracle Cloud Infrastructure, secure private links like AWS Direct Connect with OCI FastConnect (Option 2) are generally preferred because they provide lower latency and consistent throughput while minimizing egress charges. In some scenarios, routing through on-premises over VPN tunnels (Option 4) can serve as a complementary approach or backup method, although it may have higher latency. For more details, consult Oracle� documentation on FastConnect and best practices for multi-cloud connectivity.
- A. Incorrect.
Option 1: Incorrect. Deploying a separate Oracle Database in AWS no longer gives you a true multi-cloud architecture with OCI. It also defeats the purpose of leveraging Oracle Autonomous Database features in OCI.
- B. Correct.
Option 2: Correct. Pairing AWS Direct Connect with OCI FastConnect is a recommended solution for secure, low-latency multi-cloud connectivity. This method helps to minimize data egress costs by using private links rather than public internet paths.
- C. Incorrect.
Option 3: Incorrect. Public internet routing can increase latency and expose traffic to potential performance fluctuations. While encryption in transit is available, it does not fully address the need for low latency and cost optimization.
- D. Correct.
Option 4: Correct. Routing traffic through on-premises using VPN connections can be a viable fallback or complementary approach when a dedicated private connection is not immediately feasible. It provides secure tunneling, though typically at higher latency than direct interconnect options.
