問題 #153
You are building a secure containerized application on Container Engine for Kubernetes (OKE) that must access OCI resources securely using OKE Workload Identity. Which cluster type must you select during creation to enable support for OKE Workload Identity?
答案：A
解題說明：
OKE Workload Identity is anenhanced-cluster capability. Oracle ' s current Kubernetes Engine documentation explicitly lists workload identity as supported by Enhanced clusters and not supported by Basic clusters.
Workload Identity enables IAM policies to authorize individual Kubernetes workloads according to attributes such as cluster, namespace, and service account, avoiding broader permissions inherited from worker-node instance principals. Basic clusters support standard Kubernetes and OKE functionality but exclude enhanced capabilities including Workload Identity, virtual nodes, self-managed nodes, and advanced cluster add-on management. "Dedicated cluster" and "Autonomous cluster" are not the OKE cluster types used for this feature classification. Therefore, an application architecture requiring OKE Workload Identity must use an Enhanced cluster, making option A correct.
問題 #154
You have built a local container image named order-processor:1.0 and need to push it to a repository named order-services in your Phoenix region (phx) tenancy, which has the Object Storage namespace ax39m19vpw.
Which command must you run to properly tag the local image before pushing it to Container Registry?
答案：A
解題說明：
OCI Container Registry requires the destination image tag to use the structure < region-key > .ocir.io/ < tenancy-namespace > / < repository-name > : < tag > . For Phoenix, the region key is phx; the supplied tenancy namespace is ax39m19vpw; the repository is order-services; and the image tag is 1.0. Combining these values produces phx.ocir.io/ax39m19vpw/order-services:1.0. Oracle ' s current container documentation provides the same docker tag structure before an image is pushed to OCIR. The alternative commands incorrectly reorder the namespace and registry host or use an unsupported registry hostname format.
Therefore, option A correctly retags the local order-processor:1.0 image with the fully qualified OCIR repository path required for the subsequent docker push.
問題 #155
Your cloud-native banking microservice retrieves API tokens stored in OCI Vault. To meet strict security compliance standards, you must configure secret rules on these vault secrets. The security policies mandate that the secret contents must automatically expire and have their retrieval blocked 30 days after creation, and any previously used token content must never be allowed for reuse, even if the older secret version containing that content has been deleted. Which TWO configurations must you specify within the secret rules to satisfy these compliance requirements?
答案：C,E
解題說明：
OCI Vault provides both Secret Expiry Rules and Secret Reuse Rules. secret_version_expiry_interval uses an ISO 8601 duration, so P30D establishes a 30-day validity period. Setting is_secret_content_retrieval_blocked_on_expiry to true ensures secret contents cannot be retrieved after expiry, satisfying the first requirement. For the second requirement, a SECRET_REUSE_RULE prevents previously used secret contents from being reused across versions. Oracle ' s SDK documentation confirms that is_enforced_on_deleted_secret_versions=true extends that restriction even when the previous secret version has been deleted. Setting either Boolean to false would weaken the stated controls.
HSM_PURGE_RULE is not one of the documented OCI Vault secret-rule types. Therefore, C and D jointly satisfy both requirements.
問題 #156
You are tasked with configuring access for a new developer group named ops-team in OCI. Members of this group must be able to publish raw data points to a custom metric namespace named AppPerformance in the tenancy, and they must also be able to run queries to view both service and custom metrics in a target compartment named production-cmp.
Which TWO IAM policy statements must be written to satisfy these requirements?
答案：B,D
解題說明：
OCI Monitoring IAM maps the use metrics verb to metric write capability, including METRIC_WRITE and the PostMetricData operation. Oracle specifically documents the pattern Allow group < group > to use metrics in tenancy where target.metrics.namespace= ' < namespace > ' for publishing custom metric data.
Therefore, E grants publishing access specifically to AppPerformance. Querying metric data requires read metrics, which includes METRIC_READ and SummarizeMetricsData; B consequently gives the group the required query access in production-cmp. publish is not an OCI IAM policy verb, inspect permits listing metric metadata but not retrieving data points, and manage provides unnecessary privilege. B and E therefore implement the stated requirements using the appropriate least-privilege Monitoring verbs.
問題 #157
Your organization mandates that all containerized workloads deployed to Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) must utilize Kubernetes NetworkPolicy resources, such as Calico, to enforce strict micro-segmentation of traffic. You have deployed these workloads to an enhanced OKE cluster using virtual node pools to minimize infrastructure maintenance. During testing, you discover that the Calico installation fails because NetworkPolicy resources and third-party CNI policy integrations are completely unsupported on this specific node configuration. How should you resolve this security implementation challenge while continuing to use VCN-Native Pod Networking?
答案：A
解題說明：
Oracle explicitly states that virtual nodes do not support Kubernetes NetworkPolicy resources or network providers such as Calico and Cilium that provide NetworkPolicy enforcement. Virtual nodes support only OCI VCN-Native Pod Networking and cannot use Flannel or other third-party CNI plugins. By contrast, Calico can be installed with managed node pools while retaining VCN-native pod networking. This combination enables Kubernetes NetworkPolicy objects to enforce pod-level traffic controls and micro- segmentation. An IAM policy or network security list cannot substitute for Kubernetes NetworkPolicy because OCI network controls and Kubernetes pod policy enforcement operate at different layers. Therefore, when Calico-based NetworkPolicy enforcement is mandatory, migrating the workload from virtual nodes to managed node pools is the supported OKE architecture.
