NEW QUESTION # 95
Who is responsible for patching, upgrading, and maintaining the worker nodes in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE)? (Choose the best answer.)
Answer: C
Explanation:
The user is responsible for patching, upgrading, and maintaining the worker nodes in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). In OKE, the user has control over the worker nodes, which are the compute instances that run the Kubernetes worker components. As the user, you are responsible for managing and maintaining these worker nodes, including tasks such as patching the underlying operating system, upgrading Kubernetes versions, and performing any necessary maintenance activities. While Oracle provides the underlying infrastructure and support services, including managing the control plane and ensuring the availability of the OKE service, the responsibility for managing the worker nodes lies with the user. This allows you to have control and flexibility in managing your Kubernetes environment according to your specific needs and requirements.
NEW QUESTION # 96
What can you use to dynamically make Kubernetes resources discoverable to public DNS servers? (Choose the best answer.)
Answer: D
Explanation:
To dynamically make Kubernetes resources discoverable to public DNS servers, you can use ExternalDNS.
ExternalDNS is a Kubernetes add-on that automates the management of DNS records for your Kubernetes services and ingresses. It can be configured to monitor the changes in your Kubernetes resources and automatically update DNS records in a supported DNS provider. By integrating ExternalDNS with your Kubernetes cluster, you can ensure that the DNS records for your services and ingresses are automatically created, updated, or deleted based on changes in your Kubernetes resources. This allows your Kubernetes resources to be discoverable by external systems through public DNS servers.
NEW QUESTION # 97
(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: A
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 # 98
Your security operations team wants to analyze application diagnostic and access patterns across both service and custom logs. A new IAM user group named security-auditors has been formed, and members must run advanced ad-hoc queries using the OCI Logging Console Search page to parse through indexed logs in the tenancy. Your company security mandate dictates that they must only be granted the minimum required permissions necessary to successfully execute these search queries and view the results.
Which set of policy statements correctly implements this requirement?
Answer: C
Explanation:
Oracle Logging explicitly states that searching indexed logs requiresread access to the log group and read permission on log content. The documented policies are allow group GroupA to read log-groups in tenancy and allow group GroupA to read log-content in tenancy. The read log-content permission grants LOG_CONTENT_READ, which enables users to inspect service and custom log contents and execute searches. manage log-groups is unnecessarily privileged because it allows administrative operations on logging resources. inspect does not provide sufficient access to actual log content, while use log-content is commonly associated with log ingestion and agents rather than least-privilege read-only searching. Therefore, B precisely implements the minimum permissions required for the security-auditors group to use OCI Logging Search.
NEW QUESTION # 99
Your organization is deploying a high-performance distributed deep learning training workload that requires GPU-enabled bare metal Compute instances connected through an ultra-low-latency Oracle Cloud Infrastructure (OCI) RDMA cluster network. To maximize processing efficiency and comply with strict corporate OS requirements, your team must use a custom, pre-hardened Oracle Linux operating system image that is not supported by default node pools. The containerized training jobs must be orchestrated and scheduled using your existing Container Engine for Kubernetes (OKE) control plane.
Which worker node deployment model must you implement?
Answer: C
Explanation:
OKE Self-Managed Nodes, also called Bring Your Own Nodes, provide the necessary infrastructure flexibility for specialized Compute workloads. Oracle states that self-managed nodes are Compute instances that customers create themselves and then attach to an enhanced OKE cluster. Because the instances are provisioned through OCI Compute rather than a managed OKE node pool, organizations can select specialized shape and image combinations unavailable to managed or virtual nodes. Oracle specifically cites GPU shapes, HPC shapes, and high-bandwidth, ultra-low-latency RDMA cluster networks as examples suited to self-managed nodes. This model also enables custom operating-system configuration. Virtual Nodes abstract the infrastructure entirely, while Managed Node Pools constrain supported infrastructure combinations. Therefore, Self-Managed Nodes satisfy all of the stated GPU, RDMA, and custom-image requirements.
