OCI Architect Questions and Answers Rated A+ You deployed an OCI compute instance (VM.Standard2.16) to run on SQL database. After a few weeks, you need to increase disk performance by using NVMe disks but keeping the same number of CPUs. As a first step, you terminate the instance and preserve the boot volume. What's the next step? Create new instance using a *VM.DenseI02.16* shape using the preserved boot volume and move the SQL Database to *NVMe* disks. You have an OCI load balancer distributing traffic via an evenly-weighted *round robin* policy to your back end web servers weighted load balancer, but it's not distributing evenly. How do you fix it? Disable *Cookie-based* persistence on the back-end You have an *AI/ML* app running in OCI. It needs GPU and 20GGbps Network throughput. Currently using VMStandard 2.1. Which two options allow you to get required performance 1. Terminate/Create *BM.GPU2.2* using boot volume preserved but no block volume attached 2. Terminate/Create *BM.GPU2.2* using boot volume preserved and attach block volume (Keywords: BM.GPU2.2) Which 2 are regional resources in OCI Compute images Block volume backups An OCI Tenancy *Administrator isn't able to delete a user*, what can cause this issue?

(Keywords: Retention Rule) Which two components cannot be deleted in your Oracle Cloud Infrastructure Virtual Cloud Network? 1. Default *Security List* 2. Default *Route Table* A financial firm is designing an application architecture for its online trading platform that must have high availability and fault tolerance. Their Solutions Architect configured the application to use OCI Object storage bucket located in the Phoenix Region to store large amounts of financial data. The stored financial data in the bucket must not be affected even if there is an outage in one of the *Availability Domains* or even the *entire Region*. What should the Architect do to avoid any costly service disruptions and ensure data durability? Create a *replication policy* to send data to different buckets in another OCI region.
