1Z0-997-26 Multicloud And Hybrid Practice Question
An organization has configured an OCI-Azure Interconnect. Latency measurements between an OCI compute instance and an Azure VM exceed acceptable thresholds for a synchronous database replication application. Which diagnostic step should be taken first within OCI?
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
✓
Verify the MTU settings across the OCI VCN, DRG, Azure VNet, and ExpressRoute gateway to check for fragmentation issues.
Checking the FastConnect virtual circuit status, monitoring traffic metrics, and checking for packet drops or incorrect routing paths via OCI Monitoring and Network Path Analyzer is the correct first diagnostic step.
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 OCI Database Vault on the compute instances.
Why it's wrong here
Database Vault secures database tables and has no impact on network latency.
- ✗
Replace the OCI Dynamic Routing Gateway with an Internet Gateway.
Why it's wrong here
An Internet Gateway routes over the public internet, which increases latency and is less secure.
- ✓
Verify the MTU settings across the OCI VCN, DRG, Azure VNet, and ExpressRoute gateway to check for fragmentation issues.
Why this is correct
Mismatched MTU sizes causing fragmentation can severely impact performance across cloud interconnects.
- ✗
Recreate the Azure ExpressRoute circuit in a different Azure subscription.
Why it's wrong here
Recreating the circuit without diagnostics is disruptive and unlikely to fix path latency.
