1Z0-997-26 Workload Migration Practice Question
An enterprise is migrating a legacy Java application that requires sticky sessions and complex path-based routing rules to OCI. The migration plan requires zero dropped connections during backend server updates. Which OCI Load Balancer configuration feature should you implement?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure backend server draining with a specified timeout period in the backend set.
OCI Load Balancer supports backend set draining (draining timeout), which allows existing established connections to complete gracefully while new connections are routed to updated backend servers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable IP Hash load balancing policy without health checks.
Why it's wrong here
Disabling health checks is dangerous and IP hash does not solve connection draining during maintenance.
- ✗
Use OCI Web Application Firewall (WAF) rate limiting rules to drop incoming traffic during maintenance.
Why it's wrong here
Dropping traffic causes connection failures rather than graceful draining.
- ✓
Configure backend server draining with a specified timeout period in the backend set.
Why this is correct
Backend draining ensures active client requests finish processing before a server is taken out of rotation during deployments or cutovers.
- ✗
Configure a Layer 4 TCP Network Load Balancer with TCP session persistence disabled.
Why it's wrong here
Layer 4 Network Load Balancers do not inspect HTTP paths or provide sticky session management required by the Java application.
