You want to push a new image in the Oracle Cloud Infrastructure (OCI) Registry. Which TWO actions would you need to perform? (Choose two.)
Answer: B,E
Explanation:
To push a new image to the Oracle Cloud Infrastructure (OCI) Registry, you would need to perform the following two actions: Assign a tag via Docker CLI to the image: Before pushing the image, you need to assign a tag to it using the Docker CLI. The tag helps identify the image and associate it with a specific version or label. Generate an auth token to complete the authentication via Docker CLI: To authenticate and authorize the push operation, you need to generate an auth token. This token is used to authenticate your Docker CLI with the OCI Registry, allowing you to push the image securely. Note: Generating an API signing key, assigning an OCI defined tag via OCI CLI, and generating an OCI tag namespace are not required steps for pushing a new image to the OCI Registry.

You are developing a cloud native serverless application where uploaded PDF documents inside an OCI Object Storage bucket must automatically trigger an OCI Function for text processing. You have created an OCI Events rule configured with the condition eventType: com.oraclecloud.objectstorage.createbucket matching the bucket ' s compartment. However, when test files are uploaded, the function does not trigger.
Which TWO actions must you perform to successfully implement and troubleshoot this event-driven integration?
Answer: B,D
Explanation:
Object-level state changes in OCI Object Storage donot emit Events by default. Oracle requires the bucket ' sEmit Object Eventscapability to be enabled before object create, update, or delete events are generated. In addition, the rule must use the correct event type. com.oraclecloud.objectstorage.createbucket represents creation of a bucket itself, whereas uploading a new object generates com.oraclecloud.objectstorage.
createobject. Therefore, the current rule can never match ordinary PDF uploads. Dynamic groups are not used to assign identities to buckets, Events does not require permission to read the actual object ' s contents, and no VCN Service Gateway is necessary for this native OCI service integration. Consequently, B and D are required.
NEW QUESTION # 54
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?
Answer: D
Explanation:
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.
NEW QUESTION # 55
(CHK_4 > 2) You have a scenario where a DevOps team wants to store secrets in Oracle Cloud Infrastructure (OCI) Vault so that it can inject the secrets into an app ' s environment variables (for example, MYSQL_DB_PASSWD) at deployment time. Which is NOT valid about managing secrets in the OCI Vault service?
Answer: D
Explanation:
The correct answer is: " A unique OCID is automatically generated for each secret and remains unchanged even when creating a new secret version. " The statement that is NOT valid about managing secrets in the OCI Vault service is: " A unique OCID is automatically generated for each secret and remains unchanged even when creating a new secret version. " In OCI Vault, a secret is identified by its OCID (Oracle Cloud Identifier), which is a unique identifier for each resource in Oracle Cloud Infrastructure. However, when a new secret version is created for an existing secret, the OCID remains the same for the secret itself, but a new OCID is generated for the secret version. This allows you to track and manage different versions of a secret while maintaining a consistent OCID for the secret itself. The other statements mentioned are valid: You can manually create new secrets as well as new secret versions using the OCI Console. This means you have control over creating and managing secrets within the Vault service. A secret reuse rule prevents the use of secret contents across different versions of a secret. This ensures that each secret version maintains its own unique set of contents and avoids accidental reuse or sharing of secrets across versions. By default, new secret versions automatically expire in 90 days unless you configure an expiry rule. This helps enforce good security practices by automatically rotating secrets periodically, reducing the risk of unauthorized access in case of compromise. Therefore, the statement that is NOT valid is the one regarding the uniqueness and consistency of the OCID when creating new secret versions.
NEW QUESTION # 56
You are writing a script to automate operational reports and need to extract custom aggregated CPU utilization metrics for a set of compute instances within your compartment. Which OCI CLI command should you run to retrieve this aggregated metric data from the OCI Monitoring service?
Answer: C
Explanation:
The correct command is oci monitoring metric-data summarize-metrics-data. Oracle defines this operation specifically for retrieving aggregated metric data that matches a Monitoring Query Language (MQL) expression. The command accepts parameters including the compartment OCID, metric namespace, and -- query-text, which can contain expressions such as CpuUtilization[1m].mean(). The post operation performs the opposite function: it publishes custom metric data into OCI Monitoring rather than retrieving it. query and retrieve are not valid subcommands under oci monitoring metric-data. Therefore, when an automation script must obtain aggregated CPU utilization or another metric series from Monitoring, summarize-metrics-data is the documented OCI CLI operation.
