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 Groups' 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. A compute instance with multiple block volumes attached cannot move when a compartment is moved.
• C. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
• D. 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.

A data analytics company has been building Its now generation big data and analytics platform on Oracle Cloud Infrastructure (OCI). They need a storage service that provide the scale and performance that their big data applications require such as high throughput to compute nodes with low latency file operations in addition, their data needs to be stored redundantly across multiple nodes In a single availability domain and allows concurrent connections from multiple compute Instances hosted on multiple availability domains.
Which OCI storage service can you use to meet i his requirement?

• A. File System Storage
• B. Archive storage
• C. Object Storage
• D. Block Volume

As an administrator you want to give users of ObjectWriters group full access to bucket Bucket-A and its objects in compartment comp-images. You want users of ObjectWriters to not be able to access or modify properties of any other buckets and its objects in the compartment comp-images.
Select the statement(s) below that will best define your IAM policies.

• A. Allow group ObjectWriters to inspect buckets in compartment comp-images Allow group ObjectWriters to read buckets in compartment comp-images where target.bucket.name=' Bucket-A" Allow group ObjectWriters to manage objects in compartment comp-images where target.bucket.name=' Bucket-A'
• B. Allow group ObjectWriters to manage buckets in compartment comp-images where target.bucket.name=' Bucket-A'
• C. Allow group ObjectWriters to mange buckets in compartment comp- images Allow group ObjectWriters to manage objects in compartment comp-images where target.bucket.name= 'Eucket-A'
• D. Allow group ObjectWritexs to read buckets in compartmentcomp-images Allow group ObjectWriters to manage objects in compartment comp- images where target.bucket.name= 'Bucket-A'

A fast growing E-commerce company has deployed their online shopping application on Oracle Cloud Infrastructure. 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. 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.
• C. Autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room for scaling further.
• D. The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation.
