1Z0-1151-25 Question 20
Single answerA retail company wants to process real-time sales data gathered from an AWS-based ecommerce platform when the data arrives in an Oracle Autonomous Database instance running in OCI. The solution must minimize latency and provide a secure, private connection between the AWS front-end application and the OCI database. Which approach is recommended for achieving this goal?
- A
Leverage an IPsec VPN connection with a NAT gateway configured on OCI to handle data traffic in real time
- B
Implement Oracle Cloud Infrastructure FastConnect integrated with AWS Direct Connect or an approved partner for private connectivity
- C
Move the data hourly from AWS to OCI using Oracle Data Transfer Service and load it into the Autonomous Database instance
- D
Configure a public internet connection to OCI with SSL/TLS encryption for secure data traffic
Show answer and explanation
Correct answer: B
Explanation
FastConnect paired with AWS Direct Connect (or a qualified partner) is a common multicloud solution for reducing latency and ensuring a secure, private connection between AWS workloads and OCI services such as Oracle Autonomous Database. This aligns with Oracle� recommended multicloud architecture patterns, as documented in Oracle Cloud Infrastructure� multicloud connectivity guidelines.
- A. Incorrect.
Option 1: An IPsec VPN with a NAT gateway can be used for basic connectivity but often lacks the consistent low latency needed for real-time data processing at scale. While secure, it may not be ideal for high-throughput, low-latency requirements associated with real-time analytics.
- B. Correct.
Option 2: FastConnect integrated with AWS Direct Connect or an approved partner offers dedicated, high-bandwidth, and low-latency connectivity between AWS and OCI. This is the recommended approach for secure, real-time data transfer to an Autonomous Database in OCI, as it minimizes latency compared to public internet or VPN solutions.
- C. Incorrect.
Option 3: Oracle Data Transfer Service is typically used for large data migrations or bulk transfers, such as initial migrations or periodic batch uploads, rather than continuous real-time streams. Using it hourly does not meet the stated requirement for real-time processing.
- D. Incorrect.
Option 4: A public internet connection with SSL/TLS encryption is secure, but it introduces variability in performance and latency, making it less ideal for low-latency real-time analytics.
