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 two options do you need to implement together to migrate your on premises databases to OCI?

• A.Use Oracle GoldenGate replication to keep on premises database online during migration.
• B.Convert on-premises databases to PDB, upgrade to 19c, and encrypt Migration.
• C.Retain all legacy structures and unsupported features (e.g. taw U>Bs) In the onuses databases for migration.
• D.Retain changes to Oracle shipped privileges, stored procedures or views In the on-premises databases.
• E.Use Oracle Data Guard to keep on premises database always active during migration

All three Data Guard Configuration are fully supported on Oracle Cloud infrastructure (OCI). You want to deploy a maximum availability architecture (MAA) for database workload.
Which option should you consider while designing your Data Guard configuration to ensure best RTO and PRO without causing any data loss?

• A.Configure ''Maximum Scalability" mode which provides the highest level of scalability without compromising the availability of the primary database.
• B.Configure ''Maximum Availability" mode in SYNC mode between two availability domains (same region), and use the Maximum Availability mode in SYNC mode between two regions.
• C.Configure "Maximum Performance" mode In SYNC mode between two availability domains (same region) which provides, the highest level of data protection that is possible without affecting the performance of the primary database.
• D.Configure "Maximum Protection" mode which provides zero data loss If the primary database fails.

You are running a legacy application In a compute Instance on Oracle Cloud Infrastructure (OCI). To provide enough space for it to store internal data, a block volume is attached to the instance in paravirtualized mode. Your application is not resilient to crash-consistent backup.
What should you do to securely backup the block volume?

• A.Before creating a backup, save your application data and detach the block volume.
• B.Create a backup, detach the block volume and save your application data.
• C.Create a volume group, add the block volume and boot volume and then run the volume group backup.
• D.Use the block volume clone feature to save cost and speed up the backup process.

An OCI Architect is working on a solution consisting of analysis of data from clinical trials of a pharmaceutical company. The data is being stored in OCI Autonomous Data Warehouse (ADW) having 8 CPU Cores and 70 TB of storage. The architect is planning to setup autoscaling to respond to dynamic changes in the workload.
Which of the following needs to be considered while configuring auto scaling? Choose two

• A.Auto scaling also scales IO throughput linearly along with CPU
• B.The maximum CPU cores that will be automatically allocated for this database is 16 CPUs
• C.The database memory SGA and PGA will not get affected by the changes in the number of CPUs during auto scaling
• D.Enabling auto scaling does not change the concurrency and parallelism settings

Your organization is planning on using Oracle Cloud Infrastructure (OCI) File Storage Service (FSS). You will be deploying multiple compute instance in Oracle Cloud Infrastructure (OCI) and mounting the file system to these compute instances. The file system will hold payment data processed by a Database instance and utilized by compute instances to create a overall inventory report. You need to restrict access to this data for specific compute instances and must be allowed/blocked per compute instance's CIDR block.
Which option can you use to secure access?

• A.Use stateless Security List rule to restrict access from known IP addresses only.
• B.Use 'Export option' feature of FSS to restrict access to the mounted file systems.
• C.Create and configure OCI Web Application Firewall service with built in DNS based intelligent routing.
• D.Create a new VCN security list, choose SOURCE TYPE as Service and SOURCE SERVICE as FSS. Add stateless ingress and egress rules for specific P address and CIDR blocks.
