A retail company has recently adopted a hybrid architecture. They have the following requirements for their end-to-end Connectivity model between their on-premises data center and Oracle Cloud Infrastructure (OC1) region
* Highly available connection with service level redundancy
* Dedicated network bandwidth with low latency
Which connectivity setup is the most cost effective solution for this scenario?
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?
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?
Which three options are available to migrate an Oracle database 12.x from an on-premises environment to Oracle Cloud Infrastructure (OCI)?
You are working with a customer who needs to attach an Oracle Cloud Infrastructure (OCI) block volume to a VM instance with read/write access type. The customer wants to know if the number of IOPS and throughput performance differs between the following two choices:
• Option A: attach a single 1 TB block volume to the VM instance
• Option B: attach two separate 500 GB block volumes In a RAID 0 array configuration to the VM instance
You can assume that the customer is using iSCSI attachment type to attach the volumes to the instance. In addition, you can assume 1 MB block size for throughput and 4 KB block size for IOPS consideration.
How should you respond to the customer?
You are tasked with migrating an online shopping website to Oracle Cloud Infrastructure (OCI) and decide to use a Load Balancer. You have configured the backend set with the round robin policy. During the testing phase, you noticed that users are losing items from their shopping carts when they navigate to different pages.
How should you implement a solution to this problem?
A retailer bank is currently hosting their mission critical customer application on-premises. The application has a standard 3 tier architecture -4 application servers process the incoming traffic and store application data in an Oracle Exadata Database Server. The bank has recently has service disruption to other inter applications to they are looking to avoid this issue for their mission critical Customer Application.
Which Oracle Cloud Infrastructure services should you recommend as part of the DR solution?
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 data analytics company has been building its next-generation big data and analytics platform on Oracle Cloud Infrastructure (OCI) in the US East (Ashburn) region. They need a storage service that provides the scale and performance that their big data applications require such as high throughput to compute nodes coupled with low latency file operations.
In addition, they need to allow concurrent connections from multiple compute instances hosted in multiple Availability Domains and want to be able to quickly restore a previous version of the data in case of a need to roll back any major update.
Which option can they use to meet these requirements in the most cost-effective way?
You have configured backups for your Oracle Cloud Infrastructure (OCI) 2-node RAC DB systems on virtual machines. In the console, the database backup displays a Failed status.
Which of the following options is the most likely reason for this backup issue?
