A large financial services company has used 2 types of Oracle DB Systems. In Oracle Cloud Infrastructure (OCI) to store user dat a. One is running on a VM.Standard2.8 shape and the other on a VM.Standard 2.4 shape.
As business grows, data is growing rapidly on both the databases and performance is also degrading. The company wants to address this problem with a viable and economical solution.
As the solution architect for that company you have suggested that they move their databases to Autonomous Transaction Processing Serverless (ATP-S) database.
Which two factors should you consider before you arrived at that recommendation?
- A. You verified that ATP S supports the database features and options currently being used by the 2 databases.
- B. Confirm that ATP-S allows customers to compress tablespaces to reduce storage costs
- C. Validate that ATP-S will support the storage and processing requirements for the 2 databases over the life cycle of the business applications.
- D. Upon provisioning, ATP-S automatically scales up CPU to meet the application's processing requirements.
Answer: A,C
Explanation:
Not all features present in Oracle Database Enterprise Edition are available in ATP, and some some Oracle Database features are restricted, for example, database features designed for administration are not available. so you need to validate it first, You can find a complete list of the features that are not supported,

You login to your Oracle Cloud Infrastructure (OCI)account and use the 'Move Resource' option.
What will happen when you attempt moving the compute resource?
- A. The move will be successful though Compute Instance and its Public and Private IP address will stay the same. The Compute instance VNIC will still be associated with the original VCN.
- B. The move will be successful though Compute Instance Public and Private IP address changed, and it will be associated to the VCN in target compartment.
- C. The move will be successful though Compute Instance and its Public and Private IP address will stay the same. The Compute instance VNIC will need to be moved separately. The Compute instance will still be associated with the original VCN.
- D. The move will fail and you will be prompted to move the VCN first. Once VCN is moved to the target compartment, the Compute instance can be moved.
Answer: A
Explanation:
Moving Resources to a Different Compartment
Most resources can be moved after they are created. There are a few resources that you can't move from one compartment to another. Some resources have attached resource dependencies and some don't.
Not all attached dependencies behave the same way when the parent resource moves.
For some resources, the attached dependencies move with the parent resource to the new compartment.
The parent resource moves immediately, but in some cases attached dependencies move asynchronously and are not visible in the new compartment until the move is complete.
For other resources, the attached resource dependencies do not move to the new compartment. You can move these attached resources independently.
You can move Compute resources such as instances, instance pools, and custom images from one compartment to another. When you move a Compute resource to a new compartment, associated resources such as boot volumes and VNICs are not moved.
You can move a VCN from one compartment to another. When you move a VCN, its associated VNICs, private IPs, and ephemeral IPs move with it to the new compartment.

NEW QUESTION # 67
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 Availability" mode in SYNC mode between two availability domains (same region), and use the Maximum Availability mode in SYNC mode between two regions.
- B. 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.
- C. Configure "Maximum Protection" mode which provides zero data loss If the primary database fails.
- D. Configure ''Maximum Scalability" mode which provides the highest level of scalability without compromising the availability of the primary database.
Answer: A
Explanation:
https://docs.cloud.oracle.com/en-us/iaas/Content/Resources/Assets/whitepapers/best-practices-for-dr-on-oci.pdf All three Data Guard configurations are fully supported on Oracle Cloud Infrastructure. However, because of a high risk of production outage, we don't recommend using the maximum protection mode for your Data Guard configuration.
We recommend using the maximum availability mode in SYNC mode between two availability domains (same region), and using the maximum availability mode in ASYNC mode between two regions. This architecture provides you the best RTO and RPO without causing any data loss. We recommend building this architecture in daisy-chain mode: the primary database ships redo logs to the first standby database in another availability domain in SYNC mode, and then the first standby database ships the redo logs to another region in ASYNC mode. This method ensures that your primary database is not doing the double work of shipping redo logs, which can cause performance impact on a production workload.
This configuration offers the following benefits:
No data loss within a region.
No overhead on the production database to maintain standbys in another region.
Option to configure lagging on the DR site if needed for business reasons.
Option to configure multiple standbys in different regions without any additional overhead on the production database. A typical use case is a CDN application Bottom of Form

NEW QUESTION # 70
An automobile company wants to deploy their CRM application for Oracle Database on Oracle Cloud Infrastructure (OC1) DB Systems for one of major clients. In compliance with the Business Continuity Program of the client, they need to provide a Recovery Point objective (RPO) of 24 hours and a Recovery time objective (RTO) of 24 hours and Recovery Time Objective (RTO) of 1 hour.
The CRM application should be available oven in me event that an entire on Region is down.
Which approach Is the most suitable and cost effective configuration for this scenario?
- A. Deploy a 1 node VM Oracle database in one region and replicate the database to a 1 node VM Oracle database in another region using a manual setup and configuration of Oracle Data Guard.
- B. Deploy a 1 node VM Oracle database in one region. Manual Configure a Recovery Manager (RMAN) database backup schedule to take hourly database backups. Asynchronously copy the database backups to object storage in another OCI region, If the primary OCI region is unavailable launch a new 1 new VM Database in the other OCI region restore the production database from the backup.
- C. Deploy a 2 node Virtual Machine (VM) Oracle RAC database in one region and replicate the database to a 2 node VM Oracle RAC database in another region using a manual setup and configuration of Oracle Data Guard.
- D. Deploy an Autonomous Transaction Processing (Serverless) database in one region and replicate it to an Autonomous Transaction Processing (Serverless) database in another region Oracle GoldenGate.
Answer: A
Explanation:
You can configure the Autonomous Database instance as a target database for Oracle GoldenGate. But You can't set up Oracle Autonomous Database as a source database for Oracle GoldenGate.
Recovery Point objective (RPO) of 24 hours and Recovery Time Objective (RTO) of 1 hour
- To provision new VM and restore the production database from the backup on object storage, will exceed the RTO 1 hour
- You can create the standby DB system in a different availability domain from the primary DB system for availability and disaster recovery purposes. With Data Guard and switchover/failover can meet RTO
1 hour.
- RAC Database is not required in this solution. Standalone will be most suitable and cost effective
NEW QUESTION # 71
An organization has its IT infrastructure in a hybrid setup with an on-premises environment and an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) in the us-phonix-1 region. The on-premise applications communications with compute instances inside the VPN over a hardware VPN connection. They are looking to implement an Intrusion detected and Prevention (IDS/IPS) system for their OCI environment. This platform should have the ability to scale to thousands of compute of instances running inside the VCN.
How should they architect their solution on OCI to achieve this goal?
- A. There Is no need to implement an IPS/IDS system as traffic coming over IPSec VPN tunnels Is already encrypt
- B. Set up an OCI Private Load Balance! and configure IDS/IPS related health checks at TCP and/or HTTP level to inspect traffic
- C. Configure autoscaling on a compute Instance pool and set vNIC to promiscuous mode to called traffic across the vcn and send it IDS/IPS platform for inspection.
- D. Configure each host with an agent that collects all network traffic and sends that traffic to the IDS/IPS platform to inspection
Answer: D
Explanation:
in Transit routing through a private IP in the VCN you set up an instance in the VCN to act as a firewall or intrusion detection system to filter or inspect the traffic between the on-premises network and Oracle Services Network.
The Networking service lets you implement network security functions such as intrusion detection, application-level firewalls In fact, the IDS model can be host-based IDS (HIDS) or network-based IDS (NIDS). HIDS is installed at a host to periodically monitor specific system logs for patterns of intrusions. In contrast, an NIDS sniffs the traffic to analyze suspicious behaviors. A signature-based NIDS (SNIDS) examines the traffic for patterns of known intrusions. SNIDS can quickly and reliably diagnose the attacking techniques and security holes without generating an over-whelming number of false alarms because SNIDS relies on known signatures.
However, anomaly-based NIDS (ANIDS) detects unusual behaviors based on statistical methods. ANIDS could detect symptoms of attacks without specific knowledge of details. However, if the training data of the normal traffic are inadequate, ANIDS may generate a large number of false alarms.

NEW QUESTION # 74
You are a solutions architect for a global health care company which has numerous data centers around the globe. Due to the ever growing data that your company is storing, you were Instructed to set up a durable, cost effective solution to archive you data from your existing on-premises tape based backup Infrastructure to Oracle Cloud Infrastructure (OCI).
What is the most-effective mechanism to Implement this requirement?
- A. Setup an on premises OCI Storage Gateway which will back up your data to OCI Object Storage Archive tier.
- B. Setup fastConnect to connect your on premises network to your OCI VCN and use rsync tool to copy your data to OCI Object Storage Archive tier.
- C. Setup an on premises OCI Storage Gateway which will back up your data to OCI object Storage Standard tier. Use Object Storage life cycle policy management to move any data older than 30 days from Standard to Archive tier.
- D. Setup an on-promises OCI Storage Gateway which will back up your data to OCI Object Storage Standard
- E. Use the File Storage Service in OCI and copy the data from your existing tape based backup to the shared file system
Answer: A
Explanation:
Oracle Cloud Infrastructure offers two distinct storage tiers for you to store your unstructured data. Use the Object Storage Standard tier for data to which you need fast, immediate, and frequent access. Use the Archive Storage service's Archive tier for data that you access infrequently, but which must be preserved for long periods of time. Both storage tiers use the same manageable resources (for example, objects and buckets). The difference is that when you upload a file to Archive Storage, the object is immediately archived. Before you can access an archived object, you must first restore the object to the Standard tier.
you can use Storage Gateway to move files to Oracle Cloud Infrastructure Archive Storage as a cost effective backup solution. You can move individual files and compressed or uncompressed ZIP or TAR archives. Storing secondary copies of data is an ideal use case for Storage Gateway.
NEW QUESTION # 75
