NEW QUESTION # 27
(CHK_4 > 2) Which TWO statements are NOT valid regarding the Oracle Cloud Infrastructure (OCI) Streaming service? (Choose two.)
Answer: A,B
Explanation:
The two statements that are NOT valid regarding the Oracle Cloud Infrastructure (OCI) Streaming service are: A stream can be configured with either a public or a private endpoint with support for customer managed encryption keys. This statement is not valid because the OCI Streaming service currently supports only private endpoints. Customer managed encryption keys are not currently supported for OCI Streaming. OCI Streaming can support up to 2,000 requests per second to each partition. This statement is not valid because the throughput of a stream is not defined by the partition in terms of requests per second. The throughput of a stream is defined in terms of data input and output rates. Each partition provides 1 MB/sec data input and 2 MB/sec data output, but it does not correspond to a specific number of requests per second. The other statements are valid: OCI Streaming stores all data for 24 hours by default, but that can be extended up to 7 days. Although OCI Streaming automatically encrypts all data while in transit, it is the developer ' s responsibility to encrypt data at rest, if needed.
NEW QUESTION # 28
Your organization has deployed their e-commerce application on Oracle Container Engine for Kubernetes (OKE) and they are using the Oracle Cloud Infrastructure Registry (OCIR) service as their Docker image repository. They have deployed the OKE cluster using the ' custom create ' option, and their Virtual Cloud Network (VCN) has three public subnets with associated Route Tables, Security Lists, and Internet Gateway.
However, their application containers are failing to deploy. On investigation, they discover that the images are not being pulled from the designated OCIR repository, even though the YAML configuration has the correct path to the images. What is a valid concern here that needs to be further investigated?
Answer: B
Explanation:
A valid concern that needs to be further investigated in this scenario is whether the OKE cluster has a secret with the credentials of the Oracle Cloud Infrastructure Registry (OCIR) repository and if that secret is being used in the Kubernetes deployment manifest. Here ' s why this concern is relevant: Access to the OCIR repository: In order for the OKE cluster to pull images from the OCIR repository, it needs proper authentication credentials. These credentials are typically provided in the form of a secret, which contains the necessary information to authenticate with the registry. Secret in the deployment manifest: The Kubernetes deployment manifest defines how the application containers should be deployed. It includes specifications such as the container image, resource requirements, and environment variables. To pull images from a private repository like OCIR, the deployment manifest needs to reference the appropriate secret that contains the registry credentials. If the images are not being pulled from the designated OCIR repository, it suggests that either the secret with the OCIR credentials is missing or it is not properly referenced in the deployment manifest. Further investigation should focus on verifying the presence and correctness of the secret, as well as confirming that it is correctly referenced in the deployment manifest for the application containers. By ensuring the presence of the secret and proper configuration in the deployment manifest, the OKE cluster will have the necessary credentials to access the OCIR repository and successfully deploy the application containers.
NEW QUESTION # 29
You are configuring a route on an Oracle Cloud Infrastructure API Gateway to an HTTP backend service that takes up to four minutes to execute long-running analytical queries. Which timeout configuration should you apply in the API deployment specification to safely prevent a gateway timeout?
Answer: C
Explanation:
For an HTTP backend, OCI API Gateway provides readTimeoutInSeconds to control how long the gateway waits for the backend response after the connection has been established. A four-minute backend processing window requires a timeout of 240 seconds, so B is sufficient without exceeding the platform limit. Oracle documents a maximum configurable timeout value of300 secondsfor HTTP backend timeout parameters.
Therefore, the 360-second and 480-second choices exceed the supported range and would not be valid deployment values. A 120-second timeout would expire before the four-minute analytical operation can complete. Thus, 240 seconds is both within the API Gateway limit and aligned with the backend ' s maximum execution duration.
NEW QUESTION # 30
You are developing a continuous integration (CI) pipeline running on an Oracle Cloud Infrastructure (OCI) Compute instance that automatically builds and pushes container images to Container Registry (OCIR). You need to configure dynamic group membership and write the minimum required IAM policies to authorize this Compute instance to push images to repositories within a compartment named qa-compartment.
Which TWO steps must you perform to achieve this authorization?
Answer: A,C
Explanation:
OCI dynamic groups identify Compute instances using the documented instance.id attribute, making B valid.
Oracle Container Registry documentation also shows manage repos as a policy capable of authorizing image pushes within a specified compartment, making D the sufficient policy among the supplied choices. container.
instance is not a valid Compute-instance matching variable, while inspect repos provides only discovery-level permissions. use repos does not supply the repository update permissions required for pushing images. For stricter production least privilege, Oracle additionally documents conditioning a manage repos policy to specific permissions such as REPOSITORY_READ, REPOSITORY_UPDATE, and REPOSITORY_CREATE; however, that granular variant is not offered among these choices. Therefore, B and D are the correct selections.
NEW QUESTION # 31
You are developing a Python microservice that needs to consume real-time telemetry data from a specific OCI Stream partition, beginning only with new messages that are published after your consumer client connects.
Which cursor type must you specify when invoking the create_cursor API call?
Answer: C
Explanation:
The LATEST cursor type positions the consumer at the most recent point in the stream so that it receives only messages published after the cursor is created. Oracle explicitly states that a cursor based on the most recent message allows consumption only of messages subsequently added to the stream. TRIM_HORIZON has the opposite behavior: it begins with the oldest message still available inside the stream ' s retention period.
AFTER_OFFSET begins immediately after a supplied partition offset, while AT_TIME begins from a specified timestamp. Because the requirement is to ignore all historical telemetry already retained in the partition and consume only newly arriving records, LATEST is the correct cursor type for the CreateCursor operation.
