Public IP Association: For instances requiring internet access, a public IP address can be optionally assigned to the private IP address if the instance is in a public subnet. This is critical for scenarios where an instance needs to communicate with the internet or external networks. This aligns with statement D. Relevant OCI Documentation: Oracle Cloud Infrastructure Networking Overview VNICs and Private IPs These references provide additional context and detail on how private IP addresses work within OCI and clarify the correct statements. What happens to the performance level of a volume when it is detached from an instance?
B. Preemptible capacity C. On-demand capacity D. Dedicated host Explanation: On-demand capacity is the compute capacity type in Oracle Cloud Infrastructure (OCI) that allows you to provision and use compute instances whenever needed, without any long-term commitment. This flexibility is ideal for various workloads, including development, testing, and production environments, where immediate availability and scalability are crucial. Key Points: On-Demand Capacity: On -demand compute instances provide users with the flexibility to spin up instances as required and only pay for the time the instances are running. This model is most suitable for workloads with unpredictable usage patterns or short -term requirements. Flexibility and Scalability: With on-demand capacity, you can quickly scale your resources up or down based on your application's needs, ensuring that you only pay for the resources you actually use. No Commitment: Unlike reserved capacity, on -demand capacity does not require any long -term commitment or upfront payment, making it an attractive option for organizations looking to avoid capital expenditures. Reference: Oracle Cloud Infrastructure Documentation: OCI Compute Pricing Oracle Cloud Infrastructure Documentation: Compute Instance Lifecycle Explanation of Incorrect Options: A . Capacity reservation: This option allows you to reserve capacity in advance, ensuring that resources are available when needed. It's ideal for predictable workloads but may not be as cost- effective for fluctuating demands. B . Preemptible capacity: Preemptible instances are a lower -cost option where instances can be terminated by OCI if resources are needed elsewhere. This is suitable for non -critical workloads that can tolerate interruptions. D . Dedicated host: Dedicated hosts provide physical servers for your exclusive use, offering isolation and predictable performance. This option is more suitable for workloads requiring dedicated resources or compliance needs. Thus, Option C: On-demand capacity is the correct choice for most general -purpose workloads needing flexibility and immediate availability without long -term commitment. Which TWO options will accomplish a fully redundant connection from an on-premises data center to a Virtual Cloud Network (VCN) in the us -ashburn -1 region?

What would be the total meteredBytes shown by the File Storage service after the hourly update cycle is complete when you overwrite 0.5 GB of a 1 GB file?
C. Snapshots are accessible under the root directory of the file system at .snapshot/name. D. Snapshots are a consistent, point -in-time view of your file systems. Explanation: In OCI File Storage, snapshots are point -in-time, read-only copies of a file system that do not immediately consume additional storage beyond the space needed to track changes. Incorrect Statement: The statement that a new snapshot consumes more storage even if nothing has changed is incorrect. Snapshots are space -efficient; they only consume additional storage as changes are made to the file system after the snapshot is taken. If no changes are made between snapshots, the storage consumption remains minimal. Correct Statements: B . Before cloning a file system, at least one snapshot must exist, as the clone operation relies on this snapshot to create a copy. C . Snapshots are accessible under the .snapshot directory, allowing users to view and restore files from specific snapshots. D . Snapshots provide a consistent, point -in-time view of the file system, ensuring data integrity.

traffic and other applications requiring data integrity. HTTP (Hypertext Transfer Protocol): Frequently used for web traffic, it is an application -layer protocol built on top of TCP and enables communication between web browsers and servers. The combination of these protocols allows the OCI Network Load Balancer to manage diverse workloads, including web services and real -time applications. For reference: OCI Load Balancer Documentation Which policy would you write to provide admin access to all three of your existing admin groups for a shared Test compartment?
Explanation of Incorrect Options: Option A: Creating a new Object Storage bucket in another region and configuring a recycle policy to move data every 5 days does not provide real-time data availability or the fault tolerance required for a financial application. Recycle policies are intended for managing the lifecycle of data, not for high availability or disaster recovery. Option C: While lifecycle policies are useful for moving less frequently accessed data to a more cost - effective storage tier (e.g., from Standard to Archive), they do not address cross -region redundancy or real-time availability, which are critical for this use case. Option D: Copying an Object Storage bucket to a block volume is not a recommended practice for ensuring data durability and fault tolerance. Block volumes are used for persistent storage attached to compute instances, and copying object storage data to block volumes does not achieve the same level of redundancy and cross -region availability as replication policies. Thus, Option B is the correct and most efficient method for ensuring high availability and fault tolerance in this scenario.
