Question 1 of 57

You create a file system and then add a 2 GB file. You then take a snapshot of the file system.

What would be the total meteredBytes shown by the File Storage service after the hourly update cycle is complete?

2 GB

2.5 GB

3 GB

4 GB

Correct Answer: D

When you take a snapshot of a file system, the snapshot itself does not immediately use the same storage space as the original file. Instead, it only records the state of the original file at the point in time when the snapshot was taken. However, in the context of meteredBytes shown by a File Storage service, it typically accounts for both the original data and the snapshot data. Since there is a 2 GB file and a snapshot is taken, the meteredBytes would reflect the total usage, which includes both the original 2 GB and the 2 GB for the snapshot, summing up to 4 GB.

Question 2 of 57

You are in the process of migrating several legacy applications from on-premises to Oracle Cloud Infrastructure (OCI). The current servers are already virtualized. However, you notice that the version of CentOS currently running does not align with any of the Oracle-provided compute images.

How would you migrate your existing virtual server images to OCI?

Export your current image in the VDI format and copy to an Object Storage bucket. Import it as a custom image. Select native mode to ensure the best possible performance.

Export your current image in the VMDK format and copy to an Object Storage bucket. Import it as a custom image. Select native mode to ensure the best possible performance.

Export your current image in the QED format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers.

Export your current image in the QCOW2 format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers.

Correct Answer: B

To migrate your existing virtual server images to Oracle Cloud Infrastructure (OCI), you should export your current image in the VMDK format and copy it to an Object Storage bucket. Then, import it as a custom image and select native mode to ensure the best possible performance. VMDK is a widely supported format and importing it in native mode will allow the virtual machine to interact directly with OCI hardware, which ensures optimal performance. Emulated mode, on the other hand, might be useful for compatibility with legacy drivers but can lead to performance issues.

Question 3 of 57

You just got a last minute request to create a set of instances in Oracle Cloud Infrastructure (OCI). The configuration and installed software are identical for every instance, and you already have a running instance in your OCI tenancy.

Which image option allows you to achieve this task with the least amount of effort?

Bring your own image and use it as a template for the new instances.

Select an image from the OCI Marketplace.

Create a custom image and use it as a template for the new instances.

Use Oracle-provided images and customize the installation using a third-party tool.

Correct Answer: C

To create a set of instances with an identical configuration and installed software, the most efficient approach is to create a custom image from the already running instance. This custom image can then be used as a template for the new instances, ensuring that they have the exact same setup and configuration with minimal effort.

Question 4 of 57

Which THREE protocols are supported by the Oracle Cloud Infrastructure (OCI) private Network Load Balancers?

HTTP

UDP

ICMP

TCP

iSCSI

BGP

Correct Answer: B, C, D

The Oracle Cloud Infrastructure (OCI) private Network Load Balancers support Layer 4 protocols, which include TCP, UDP, and ICMP. These protocols are fundamental for network communication, with TCP being used for reliable, ordered, and error-checked delivery of data, UDP for simpler messaging that does not require guaranteed delivery, and ICMP primarily for diagnostic and control purposes. HTTP, iSCSI, and BGP operate at different layers and are not supported by OCI private Network Load Balancers.

Question 5 of 57

You have an instance running in Oracle Cloud Infrastructure (OCI) that cannot be live-migrated during an infrastructure maintenance event. OCI schedules a maintenance due date within 14 to 16 days and sends you a notification.

What would happen if you choose not to proactively reboot the instance before the scheduled maintenance due date?

You will receive another notification to reboot within the next 14 days.

The instance will get terminated.

The instance is either reboot-migrated or rebuilt in place for you.

You will receive another notification to reboot within the next 7 days.

Correct Answer: C

If you do not proactively reboot the instance before the scheduled maintenance due date, the instance is either reboot-migrated or rebuilt in place for you. This ensures that the instance remains healthy and operational after the maintenance event.
