NEW QUESTION # 15
Challenge 2 -Task 1
In deploying a new application, a cloud customer needs to reflect different security postures. If a security zone is enabled with the Maximum Security Zone recipe, the customer will be unable to create or update a resource in the security zone if the action violates the attached Maximum Security Zone policy.
As an application requirement, the customer requires a compute instance in the public subnet. You therefore, need to configure Custom Security Zones that allow the creation of compute instances in the public subnet.
Review the architecture diagram, which outlines the resoures you'll need to address the requirement:

* Check the box to include all resources in the selected compartment if applicable.
* Create the Security Zone:
* ClickCreateto finalize the security zone creation.
* Once created, note theOCIDof the security zone from the security zone details page. The OCID will be a unique identifier starting with ocid1.securityzone.
* Verify the Security Zone:
* Go to theSecurity Zonestab and locate IAD_SAP-PBT-CSZ-01.
* Confirm the associated recipe (IAD-SP-PBT-CSP-01) and the applied policies.
OCID of the Created Security Zone
* The exact OCID will be generated upon creation (e.g., ocid1.securityzone.oc1..<unique_string>).
Please enter the OCID displayed in the OCI Console after completing Step 7.
