You are working on the migration of the web application infrastructure of your company from on- premises
to Oracle Cloud Infrastructure. You need to ensure that the DNS cache entries of external clients will not
direct them to the on-premises infrastructure after switching to the new infrastructure.
Which of the following options will minimize this problem?
A. Reduce the TTL of the DNS records after the switch.
B. DNS changes propagate fast enough that it is not necessary to take any action.

D. Increase the TTL of the DNS records after the switch.
E. Reduce the TTL of the DNS records before the switch.
An eCommerce company is running on Oracle Cloud Infrastructure (OCI) and many compute instances remain unused for the most part of the year except during Black Friday and Christmas. You suggest them to use OCI's
Autoscaling feature and present them a slide to showcase the features of Autoscaling. Which option below is inaccurate in your presentation to the customer?
A. A cooldown period between Autoscaling events lets the system stabilize at the updated level.
B. When an instance pool scales in, instances are terminated in this order: the number of instances is balanced across Availability Domains, and then balanced across Fault Domains. Finally, within a Fault Domain, the newest instance is terminated first.
C. Autoscaling relies on performance metrics such as CPU utilization that are collected by OCI Monitoring service to trigger an Autoscaling event.
D. Autoscaling requires an instance pool as a pre-requisite so that it can automatically adjust the number of compute instances in an instance pool.
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. Editing custom Windows images is not supported due to hardware differences between shapes.
C. Custom images do not include the data from any attached block volumes.
D. You can create additional custom images of an instance while the instance is engaged in the image creation process.
You have to migrate your application to Oracle Cloud Infrastructure (OCI). The database is constantly being updated and needs to be online without interruptions. How can you transition the database to OCI without interrupting its use?
A. It is impossible to migrate without interruption.
B. Use an on-premises database with two-way synchronization to a cloud-based database and allow clients to connect to either databases.
C. Use an on-premises database with one-way synchronization to a cloud-based database and allow clients to connect only to the cloud database.
D. Use an on-premises database with one-way synchronization to a cloud-based database and allow clients to connect only to the on-premises database until it is synchronized.
You are responsible for migrating your on-premises legacy databases on 11.2.0.4 version to Autonomous Transaction Processing - Dedicated (ATP-D) in Oracle Cloud Infrastructure (OCI). As a solution architect, you need to plan your migration approach. Which three options do you need to implement together to migrate your on-premises databases to OCI?
A. Retain all legacy structures and unsupported features (e.g. legacy LOBs) in the on-premises databases for migration.
B. Use Oracle Data Guard to keep on-premises database always active during migration.
C. Launch Autonomous Transaction Processing - Dedicated database in OCI.
D. Retain changes to Oracle shipped privileges, stored procedures or views in the on-premises databases.
E. Convert on-premises databases to PDB, upgrade to 19c, and encrypt.
F. Use Oracle GoldenGate replication to keep on-premises database online during migration.
An E-commerce company which sells computers, tablets, and other electronics items has recently decided to move all of their on-premises infrastructure to Oracle Cloud Infrastructure (OCI). One of their on-premises application is running on an NGINX server and the Oracle Database is running in a 2 node Oracle Real Application Clusters (RAC) configuration. They cannot afford to have any application down time when they do the migration. What is an effective mechanism to migrate the customer application to OCI and set up regular automated backups?
A. Launch a compute instance and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled. Import the on-premises database to OCI VM DB Systems using Oracle Data Pump and then enable automatic backups.
B. Launch a compute instance for both the NGINX application server and the database server. Attach block volumes on the database server compute instance and enable backup policy to backup the block volumes.
C. Launch a compute instance and run an NGINX server to host the application. Deploy Exadata Quarter Rack, enable automatic backups and import the database using Oracle Data Pump.
D. Launch a compute instance and run an NGINX server to host the application. Deploy a 2 node VM DB Systems with Oracle RAC enabled. Setup Oracle GoldenGate to synchronize data from their on-premises database to OCIVM Database. Export and Import the on-premises database to OCIVM DB Systems using Oracle Data Pump, apply the GoldenGate trail files to sync up the OCI database with the on-premises database. Enable automatic backups for the OCIVM database and then cutoverthe
application from on-premises to OCI.
You have an application running in Microsoft Azure and want to use Oracle Autonomous Data warehouse (ADW) instance for running business analytics. How can you build a secure solution for such a use-case?
A. Connect the Oracle ADW in your VCN to the Microsoft Azure VNet over the internet.
B. Create a software VPN connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance.
