NEW QUESTION # 40
Which term describes an individual set of aggregated data for a metric with zero or more dimension values in the Oracle Cloud Infrastructure (OCI) Monitoring service?
Answer: D
Explanation:
Oracle Monitoring formally defines ametric streamas an individual set of aggregated data for a metric with zero or more dimension values. Different dimension combinations create distinct streams. For example, CPU utilization emitted for two separate Compute instance OCIDs can constitute two separate metric streams because the resourceId dimension differs. A metric namespace identifies the service or application emitting the metrics, such as oci_computeagent. A datapoint is an individual timestamped value within a metric stream. Oracle also uses the term metric group for limit calculations, defining it as the combination of a metric, namespace, and tenancy; that is different from the dimension-specific time-series data described in the question. Therefore, option A exactly matches Oracle ' s documented Monitoring terminology.
NEW QUESTION # 41
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?
Answer: A
Explanation:
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.
NEW QUESTION # 42
Your company has recently deployed a new web application that uses Oracle Functions. Your manager instructs you to implement monitoring metrics to manage your systems more effectively. You know that Oracle Functions automatically monitors functions on your behalf and reports metrics via Oracle Cloud Infrastructure (OCI) Monitoring. Which TWO metrics are collected and made available by this feature?
(Choose two.)
Answer: B,C
Explanation:
The correct answers are: Amount of RAM used by a function: Oracle Functions collects and reports the amount of memory (RAM) used by a function during its execution. This metric helps in monitoring and optimizing the resource consumption of functions. Length of time a function runs: Oracle Functions captures and provides the duration of function executions. This metric allows you to track the performance and responsiveness of your functions and identify any potential bottlenecks or delays. These metrics provide valuable insights into the resource utilization and performance of your functions, enabling you to monitor and optimize their behavior in the Oracle Cloud Infrastructure (OCI) environment.
NEW QUESTION # 43
You deployed a Python application to an Oracle Container Engine for Kubernetes (OKE) cluster. However, while testing you found a bug, which you rectified and then created a new Docker image. You now need to ensure that if this new image does not work once deployed, you should be able to roll back to the previous version. Using kubect1, which strategy should you use?
Answer: C
Explanation:
A rolling update is a deployment strategy that gradually replaces the old version of an application with the new version without any downtime4. OKE supports rolling updates by using the kubectl rollout command4. A rolling update allows you to roll back to the previous version if something goes wrong with the new version4.
Therefore, using a rolling update strategy with kubectl ensures that you can roll back to the previous version of your Python application if the new image does not work once deployed.Verified References: Deploy Oracle Container Engine for Kubernetes
NEW QUESTION # 44
Your organization has deployed a custom OCI Authorizer Function in a compartment named secure-auth- compartment to perform token-based validation for all ingress traffic. You have set up an API Gateway in a compartment named public-gateway-compartment with an associated dynamic group named apigw-dg containing the gateway instance. The API Gateway deployment is currently returning HTTP 500 errors because the gateway lacks the necessary permissions to invoke the authorizer function during request validation. Which minimal IAM policy statement should you write to grant the API Gateway the required permission to successfully invoke the authorizer function?
Answer: C
Explanation:
Oracle ' s documented API Gateway-to-Functions integration uses a dynamic group representing the API Gateway and an IAM policy granting that dynamic group use functions-family in the compartment containing the target Function. The use verb provides the operational permission necessary for invocation without granting unnecessary administrative control. manage functions-family would be excessively privileged because it includes lifecycle management capabilities. The read and inspect verbs are insufficient for executing a Function and, in options C and D, are also scoped to the wrong compartment. Because the authorizer resides in secure-auth-compartment, authorization must apply there. Consequently, A implements the Oracle-documented pattern and satisfies least privilege for API Gateway invocation of the custom authorizer Function.
