NEW QUESTION # 98
Which statement is NOT valid regarding autoscaling configurations in Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE)?
Answer: C
Explanation:
Oracle explicitly lists Kubernetes Cluster Autoscaler among the deploymentsnot supported when using OKE virtual nodes. Virtual nodes provide a serverless data-plane model in which Oracle manages the underlying compute capacity, so customers do not resize a conventional virtual-node pool through Kubernetes Cluster Autoscaler. Cluster Autoscaler remains applicable to managed node pools, where worker-node capacity can be increased or decreased according to scheduling demand. Oracle also identifies Vertical Pod Autoscaler as unsupported on virtual nodes, while Metrics Server is supported through a deployment method adapted for virtual nodes. Horizontal Pod Autoscaler operates at the pod/deployment level and can adjust replica counts without requiring customers to resize virtual-node infrastructure. Therefore, B is the NOT valid statement because it incorrectly claims Cluster Autoscaler can resize both managed and virtual node pools.
NEW QUESTION # 99
You are troubleshooting a containerized microservice on a development host and need to obtain its full configuration metadata, including network settings and volume mounts, in JSON format. Which command should you run to retrieve this detailed information?
Answer: B
Explanation:
The docker inspect command retrieves detailed low-level metadata for Docker objects and returns the information in JSON format by default. Oracle ' s Docker documentation explicitly states that docker inspect can obtain full information about a container in JSON format and can expose specific configuration elements through formatting options. This includes network configuration, mapped ports, mounted storage, environment details, container state, and other runtime properties. docker stats provides live CPU, memory, network, and I/O utilization rather than static configuration metadata. docker history examines the image layer history and Dockerfile-derived changes. docker system provides system-wide administration commands and cleanup operations rather than detailed inspection of an individual container. Therefore, docker inspect is the appropriate troubleshooting command.
NEW QUESTION # 100
How are cloud native application versions deployed to an OKE cluster when using a blue/green deployment strategy?
Answer: B
Explanation:
Blue/Green deployment strategy allows releasing a new version of an application using two identical environments where one of them is active at a given time. The current version of the application is provisioned on the active environment, whereas the new version gets deployed to the standby environment1. The traffic is shifted from the active to the standby environment by updating the ingress resource2. Therefore, both old and new application versions are deployed to production at the same time, but only one of them receives the traffic.

NEW QUESTION # 101
Which TWO statements accurately describe an Oracle Functions application? (Choose two.)
Answer: A,B
Explanation:
The correct statements are: A common context to store configuration variables that are available to all functions in the application. A Docker image containing all the functions that share the same configuration. A logical group of functions.Explanation: An Oracle Functions application provides a common context for functions within the application. It allows you to store configuration variables that are accessible by all the functions in the application. Functions within the same application can share the same Docker image, which contains the common configuration and dependencies. An Oracle Functions application serves as a logical group that organizes related functions. Functions within the same application can be managed collectively, and they can interact and share resources within the application context.
NEW QUESTION # 102
Your team has chosen to use master encryption key (MEK) within an Oracle Cloud Infrastructure (OCI) Vault for encrypting Kubernetes secrets associated with your microservice deployments in OCI Container Engine for Kubernetes (OKE) clusters so that you can easily manage key rotation. Which of the following is NOT valid about rotating keys in the OCI Vault service?
Answer: B
Explanation:
The correct answer is: " Once rotated, older key versions can be used for encryption until they are deleted. " The statement that is NOT valid about rotating keys in the OCI Vault service is: " Once rotated, older key versions can be used for encryption until they are deleted. " In the OCI Vault service, when you rotate a master encryption key (MEK), a new key version is automatically generated. However, once a key is rotated and a new version is created, the older key versions are no longer usable for encryption. The purpose of key rotation is to ensure that the encryption keys are regularly updated and that older keys are no longer used to protect sensitive data. This enhances security by minimizing the impact of potential key compromises. The other statements mentioned are valid: Both software and hardware security module (HSM)-protected MEKs can be rotated. This provides flexibility in choosing the type of MEK and ensures that key rotation can be performed regardless of the encryption method used. Each key version is tracked internally with separate unique OCIDs (Oracle Cloud Identifiers). This allows for easy management and tracking of different key versions within the OCI Vault service. In summary, the statement that is NOT valid is the one suggesting that older key versions can still be used for encryption until they are deleted. Key rotation is designed to ensure the use of the latest key version and to retire older key versions to enhance security.
