Question 1
- You are responsible for migrating your on-premises legacy databases on 11.2.0.4 version to Autonomous
  Transaction Processing - Dedicated (ATP-D) in OracleCloud 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.
  
  Answer: A,C
Question 2
- You have been asked to implement a bespoke financial application in Oracle Cloud Infrastructure using virtual
  machine instances controlled by Autoscaling across multiple Availability Domains. The application stores
  transaction logs, intermediate transaction data, and audit data and needs to store this on a persistent, durable
  data store accessible from all of the application servers. The application requires the file system to be mounted
  in the /audit folder on the
  Linux file system. The system needs to tolerate the failure of two or more Fault Domains and still maintain
  data integrity. The solution should be as low maintenance as possible.
  What storage architecture should you suggest?
  
  A : Use locally attached NVMe instances andconfigure RAID 0 replication between servers.
  
  B : Implement a single instance and install an NFS server, configure and create an NFS share, and mount this as /audit on the application instances.
  
  C : Store the data on Oracle Object Storage mounted at the/audit mount point on all the Linux instances using the default mount options.
  
  D : Use File Storage Service(FSS). Configure FSS to operate from all Availability Domains the application servers operate in and mount the file system in the /audit folder.
  
  Answer: D
Question 3
- 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 supporteddue 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.
  
  Answer: D
Question 4
- A large financialcompany has a web application hosted in their on-premises data center. They are migrating
  their application to Oracle Cloud Infrastructure (OCI) and require no downtime while the migration is
  on-going. In order to achieve this, they have decided to divertonly 30% of the application works fine, they
  divert all traffic to OCI.
  As a solution architect working with this customer, which suggestion should you provide them?
  
  A : Use OCI Traffic management with failover steering policy and distribute the trafficbetween OC1 and on premises infrastructure.
  
  B : Use OCI Traffic management with Load Balancing steering policy and distribute the traffic between OCI and on premises infrastructure.
  
  C : Use an OCI load Balancer and distribute the traffic between OCI and on premises infrastructure.
  
  D : Use VPN connectivity between on premises Infrastructure and OCI, and create routing tables to distribute the traffic between them
  
  Answer: B
Question 5
- 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 :
  Setup IPsec VPN as your primary connection, and a FastConnect virtual circuit as a backup connection. Use separate edge devices in your on-premises data canter for each connection from your edge devices, advertise more specific routes IPSec VPN, and specific routes through the backup FastConnect virtual circuit
  
  B :
  SetupFastConnect virtual circuit as your primary connection, and a second FastConnect virtual circuit as a backup connection. Use separate edge devices in your FastConnect physical connectivity is redundant Use a single edge device in your on premises datacenter for each connection From yc device, advertise more specific routes via primary FastConnect virtual circuit, and less specific routes through t backup FastConnect circuit
  
  C :
  Setup FastConnect virtual circuit as your primary connection, and an IPSecVPN as a backup connection. Use separate edge devices in your on-premises data center for each connection. From your edge devices, advertise more specific routes through FastConnect virtual circuit, and more specific routes through the backup IPSec VPN path.
  
  D :
  Setup IPSec VPN as your primary connection, and a second IPSec VPN as a backup connection. Use separate edge devices in your on p data center for each connection. From your edge devices, advertise more specific routes via primary IPSec VPN. and lessspecific rod the backup IPSec VPN.
