Question 16

An upcoming e-commerce company has deployed their online shopping application on OCI. The application was deployed on compute instances with autoscaling configuration for application servers fronted by a load balancer and OCI Autonomous Transaction Processing (ATP) in the backend.
In order to promote their e-commerce platform 50% discount was announced on all the products for a limited period. During the day 1 of promotional period it was observed that the application is running slow and company's hotline is flooded with complaints.
What could be two possible reasons for this situation?

A.The health check on some of the backend servers has failed and the load balancer was rebooting these servers.

B.The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation

C.The autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room of scaling

D.As part of autoscaling, the load balancer shape has dynamically changed to a larger shape to handle more incoming traffic and the system was slow for a short time during this change

Question 17

You have deployed a multi-tier application with multiple compute instances in Oracle Cloud Infrastructure. You want to back up these volumes and have decided to use Volume Group's feature. The Block volume and Compute instances exist in different compartments within your tenancy.
Periodically. a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.
What could be the cause?

A.You are exceeding your volume group backup quota configured.

B.You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.

C.Compute instance with multiple block volumes attached cannot move when a compartment is moved.

D.The Identity and Access Management policy allowing backup failed to move when the compartment was moved.

Question 18

Which of the following is NOT a good use case for the Oracle Cloud Infrastructure (OCI) Streaming service?

A.Meeting compliance requirements for data to remain unchanged over a long time, so that it can be retrieved for audit purposes.

B.Ingesting metric and log data to help make critical operational data more quickly available for indexing, analysis, and visualization.

C.Messaging with a pull-based communication model and the ability to feed multiple consumers with the same data independently.

D.Providing a unified entry point for cloud components to report their life cycle events for audit, accounting, and related activities.

Question 19

A company is running High Performance Computing workloads on Oracle Cloud Infrastructure and are using OCI bare metal compute shape. They have decided to create a custom image of the bare metal instance's boot disk and use it to launch other instances.
Which of the following is a NOT a true statement?

A.Before you create a custom image of an instance, you must disconnect all iSCSI attachments and remove all iscsid node configurations from the instance.

B.You can create additional custom images of an instance while the instance is engaged in the image creation process.

C.Editing custom Windows images is not supported due to hardware differences between shapes.

D.Custom images do not include the data from any attached block volumes.

Question 20

You have been asked to implement a bespoke financial application in Oracle Cloud Infrastructure using virtual machine instances controlled by Autoscaling across multiple Availability Domains. The application stores transaction logs, intermediate transaction data, and audit data and needs to store this on a persistent, durable data store accessible from all of the application servers. The application requires the file system to be mounted in the /audit folder on the Linux file system. The system needs to tolerate the failure of two or more Fault Domains and still maintain data integrity. The solution should be as low maintenance as possible.
What storage architecture should you suggest?

A.Implement a single instance and install an NFS server, configure and create an NFS share, and mount this as /audit on the application instances.

B.Store the data on Oracle Object Storage mounted at the /audit mount point on all the Linux instances using the default mount options.

C.Use File Storage Service(FSS). Configure FSS to operate from all Availability Domains the application servers operate in and mount the file system in the /audit folder.

D.Use locally attached NVMe instances and configure RAID 0 replication between servers.
