NEW QUESTION # 18
You have been tasked with provisioning an Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) cluster to deploy new applications and manage existing ones. Which two statements are FALSE?
- A. When a cluster's Kubernetes API endpoint has a public IP address, you can access the cluster in Cloud Shell by setting up a kubeconfig file
- B. To access the cluster using kubectl, you have to set up a Kubernetes configuration file stored in the $HOME/.kube directory
- C. To access the cluster using kubectl, you have to set up a Kubernetes manifest file stored in the $HOME/.manifest directory
- D. The only available option when a cluster's Kubernetes API endpoint has a public IP address is to control the cluster locally using kubectl and the Kubernetes Dashboard
Answer: C,D
Explanation:
Setting up a Kubernetes manifest file in the $HOME/.manifest directory is not a standard practice for accessing a Kubernetes cluster using kubectl. Manifest files are used to define and manage Kubernetes resources, such as pods, deployments, and services, but they are not used for configuring access to the cluster.
While controlling the cluster locally using kubectl and the Kubernetes Dashboard is one way to interact with a cluster, it is not the only available option when a cluster's Kubernetes API endpoint has a public IP address. You can also access and manage the cluster remotely using kubectl from any environment that has network connectivity to the cluster.
NEW QUESTION # 19
You are a migration architect responsible for managing data storage solutions in Oracle Cloud Infrastructure (OCI). You configured a Storage Gateway file system on a local host running in an on-premises datacenter, which maps to an Object Storage bucket with an identical name in OCI. What happens when a file is written to a Storage Gateway file system?
- A. The file is stored locally on the host machine
- B. The file is replicated to multiple Object Storage buckets for redundancy
- C. The file is written as an object with the same name in the associated Object Storage bucket
- D. The file is uploaded to OCI Object Storage synchronously
Answer: C
Explanation:
When a file is written to a Storage Gateway file system, it is written as an object with the same name in the associated Object Storage bucket in OCI. This allows for seamless integration and synchronization between the local file system and the cloud-based Object Storage.
NEW QUESTION # 20
You have set up cross-region replication for a block volume in the US West (Phoenix) region, choosing US West (San Jose) as the destination. Now, you want to create a new volume from the volume replica in the US West (San Jose) region. What should you do?
- A. No action required. By default, the replica is available as a block volume
- B. Activate the replica
- C. Trigger the replica
- D. Initialize the replica
Answer: B
Explanation:
Activating the replica is the correct action to take in order to make the volume replica usable as a block volume in the US West (San Jose) region. This step ensures that the replica is ready for use and can be attached to instances for storage purposes.

NEW QUESTION # 27
How does containerization differ from virtualization in terms of resource optimization?
- A. Containers require a full operating system to run, whereas virtual machines share a single operating system
- B. Containerization allows for more efficient utilization of hardware resources by sharing the host operating system
- C. Virtualization maximizes efficiency by running multiple applications on the same OS kernel
- D. Virtualization offers more flexibility in terms of application dependencies
Answer: B
Explanation:
Containerization allows for more efficient utilization of hardware resources by sharing the host operating system. Containers only package the application and its dependencies, running on top of the host OS without the need for a separate guest OS.
NEW QUESTION # 28
Which option best describes the term Inventory Asset in the context of Oracle Cloud Migrations (OCM) service?
- A. Virtual Machines that have been specifically selected to migrate to OCI within the OCM UI
- B. Virtual Machines that have been automatically discovered and listed in the OCM UI
- C. An OCI Compute instance representing the migrated on-premises asset in the OCM UI
- D. The entire on-premises environment that is subject to discovery and analysis by OCM
Answer: A
Explanation:
Virtual Machines that have been specifically selected to migrate to OCI within the OCM UI are considered Inventory Assets. These assets are the ones that will undergo the migration process to Oracle Cloud Infrastructure as part of the OCM service.
NEW QUESTION # 29
Which statement accurately describes the routing mechanism within a Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure (OCI)?
- A. Each subnet within a VCN employs multiple route rules, allowing for diverse routing paths based on traffic priorities
- B. VCN local routing necessitates manual configuration of route rules to facilitate infrastructure communication
- C. If no route rule matches the network traffic you intend to route outside the VCN, the traffic is sent to the Internet
- D. A subnet in a VCN is associated with a single route table, dictating how outbound traffic from all Virtual Network Interface Cards (VNICs) within that subnet is directed
Answer: D
Explanation:
In Oracle Cloud Infrastructure (OCI), a subnet in a Virtual Cloud Network (VCN) is indeed associated with a single route table. This route table determines how outbound traffic from all Virtual Network Interface Cards (VNICs) within that subnet is directed, providing a centralized control mechanism for routing within the VCN.
