1Z0-997-26 Security Practice Question
Your development team needs to deploy applications into an OCI Security Zone. They attempt to create a compute instance with a public IP address attached, but the operation fails. Why did this happen?
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
✓
Security Zones explicitly prohibit public IP addresses on compute instances to prevent external exposure.
Security Zones strictly prohibit resources from having public IP addresses to prevent accidental exposure to the internet, blocking non-compliant API requests.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Security Zones explicitly prohibit public IP addresses on compute instances to prevent external exposure.
Why this is correct
Security Zones enforce maximum security policies, which include blocking public IP creation on compute resources.
- ✗
The VCN lacks an Internet Gateway.
Why it's wrong here
While an Internet Gateway is required for internet routing, Security Zone guardrails proactively block public IPs regardless.
- ✗
The OCI Vault service is offline.
Why it's wrong here
Vault status does not impact compute IP assignment.
- ✗
The team lacks IAM permissions to create compute instances.
Why it's wrong here
The failure is due to Security Zone policy guardrails, not standard IAM authorization.
