NEW QUESTION 12
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 Protection" mode which provides zero data loss If the primary database fails.
- C. Configure ''Maximum Scalability" mode which provides the highest level of scalability without compromising the availability of the primary database.
- D. 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.
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

An online Stock trading application is deployed to multiple Availability Domains in the us phoenix-1 region. Considering the high volume of transactions that the trading application handles, the company has hired you to ensure that the data stored by the application available, and disaster resilient. In the event of failure, the Recovery lime Objective (UK)) must be less than 2 hours to meet regulator requirements.
Which Disaster Recovery strategy should be used to achieve the RTO requirement In the event of system failure?
- A. Configure hourly block volumes backups through the Storage Gateway service.
- B. Configure hourly block volumes backups using the Oracle Cloud Infrastructure (OCI) Command Line Interface (CLI)
- C. Store hourly block volumes backup to NVMe device under a compute instance and generate a custom Image every 5 minutes.
- D. Configure your application to use synchronous master slave data replication between Availability Domains.
Answer: B
Explanation:
You can use the CLI, REST APIs, or the SDKs to automate, script, and manage volume backups and their lifecycle.
Planning Your Backup
The primary use of backups is to support business continuity, disaster recovery, and long-term archiving requirements. When determining a backup schedule, your backup plan and goals should consider the following:
Frequency: How often you want to back up your data.
Recovery time: How long you can wait for a backup to be restored and accessible to the applications that use it. The time for a backup to complete varies on several factors, but it will generally take a few minutes or longer, depending on the size of the data being backed up and the amount of data that has changed since your last backup.
Number of stored backups: How many backups you need to keep available and the deletion schedule for those you no longer need. You can only create one backup at a time, so if a backup is underway, it will need to complete before you can create another one. For details about the number of backups you can store

Autonomous Database is an Oracle Managed and Secure environment.
A physical database can't simply be migrated to autonomous because:
- Database must be converted to PDB, upgraded to 19c, and encrypted
- Any changes to Oracle shipped privileges, stored procedures or views must be removed
- All legacy structures and unsupported features must be removed (e.g. legacy LOBs) GoldenGate replication can be used to keep database online during migration
NEW QUESTION 17
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. 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.
- B. 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.
- C. 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.
- D. 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.
Answer: C
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

You have provisioned a new VM.DenseIO2.24 compute instance with local NVMe drives. The compute instance is running production application. This is a write heavy application, with a significant Impact to the business it the application goes down.
What should you do to help maintain write performance and protect against NVMe devices failure.
- A. Configure RAID 6 for NVMe devices.
- B. Configure RAID 1 for NVMe devices.
- C. NVMe drive have built in capability to recover themself so no other actions are required
- D. Configure RAID 10 for NVMe devices.
Answer: D
Explanation:
VM.DeselO2.24 compute instance include locally attached NVMe devices. These devices provide extremely low latency, high performance block storage that is ideal for big data, OLTP, and any other workload that can benefit from high-performance block storage.
A protected RAID array is the most recommended way to protect against an NVMe device failure. There are three RAID levels that can be used for the majority of workloads:
RAID 1: An exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks RAID 10: Stripes data across multiple mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved RAID 6: Block-level striping with two parity blocks distributed across all member disks If you need the best possible performance and can sacrifice some of your available space, then RAID 10 array is an option.
NEW QUESTION 19
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. Use the File Storage Service in OCI and copy the data from your existing tape based backup to the shared file system
- C. 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.
- D. Setup an on-promises OCI Storage Gateway which will back up your data to OCI Object Storage Standard
- E. 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.
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 22
You are part of a project team working in the development environment created in OCI. You have realized that the CIDR block specified for one of the subnet in a VCN is not correct and want to delete the subnet. While deleting you are getting an error indicating that there are still resources that you must delete first. The error includes the OCID of the VNIC that is in the subnet.
Which of the following action you will take to troubleshoot this issue?
- A. Use OCI CLI to call "GetVnic" operation to find out the parent resource of the VNIC
- B. Copy and Paste OCID of the VNIC in the search box of the OCI Console to find out the parent resource of the VNIC
- C. Use OCI CLI to delete the VNIC first and then delete the subnet
- D. Use OCI CLI to delete the subnet using --force option
Answer: A
Explanation:
VCN, it must first be empty and have no related resources or attached gateways To delete a VCN's subnets, they must first be empty.
Note: When you create one of the preceding resources, you specify a VCN and subnet for it. The relevant service creates at least one VNIC in the subnet and attaches the VNIC to the resource. The service manages the VNICs on your behalf, so they are not readily apparent to you in the Console. The VNIC enables the resource to communicate with other resources over the network. Although this documentation commonly talks about the resource itself being in the subnet, it's actually the resource's attached VNIC.
If the subnet is not empty, you instead get an error indicating that there are still resources that you must delete first. The error includes the OCID of a VNIC that is in the subnet (there could be more, but the error returns only a single VNIC's OCID).
You can use the Oracle Cloud Infrastructure command line interface (CLI) or another SDK or client to call the GetVnic operation with the VNIC OCID. The response includes the VNIC's display name. Depending on the type of parent resource, the display name can indicate which parent resource the VNIC belongs to. You can then delete that parent resource, or you can contact your administrator to determine who owns the resource. When the VNIC's parent resource is deleted, the attached VNIC is also deleted from the subnet. If there are remaining VNICs in the subnet, repeat the process of determining and deleting each parent resource until the subnet is empty. Then you can delete the subnet.
For example, if you're using the CLI, use this command to get information about the VNIC.
oci network vnic get --vnic-id <VNIC_OCID

Answer: A,E
Explanation:
The Oracle Services Network is a conceptual network in Oracle Cloud Infrastructure that is reserved for Oracle services. These services have public IP addresses that you typically reach over the internet. However, you can access the Oracle Services Network without the traffic going over the internet. There are different ways, depending on which of your hosts need the access:
Hosts in your on-premises network:
- Private access through a VCN with FastConnect private peering or VPN Connect: The on-premises hosts use private IP addresses and reach the Oracle Services Network by way of the VCN and the VCN's service gateway.
- Public access with FastConnect public peering: The on-premises hosts use public IP addresses.
regarding which Fastconnect Public peering: To access public services in Oracle Cloud Infrastructure without using the internet. For example, Object Storage, the Oracle Cloud Infrastructure Console and APIs, or public load balancers in your VCN. Communication across the connection is with IPv4 public IP addresses. Without FastConnect, the traffic destined for public IP addresses would be routed over the internet. With FastConnect, that traffic goes over your private physical connection.
so Answer 4 will be the best answer that meets the customer requirement A service gateway lets your virtual cloud network (VCN) privately access specific Oracle services without exposing the data to the public internet. No internet gateway or NAT is required to reach those specific services. The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the Oracle service travels over the Oracle network fabric and never traverses the internet.
Object Lifecycle Management lets you automatically manage the archiving and deletion of objects. By using Object Lifecycle Management to manage your Object Storage and Archive Storage data, you can reduce your storage costs and the amount of time you spend managing data.

NEW QUESTION 32
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. 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.
- B. Use stateless Security List rule to restrict access from known IP addresses only.
- C. Create and configure OCI Web Application Firewall service with built in DNS based intelligent routing.
- D. Use 'Export option' feature of FSS to restrict access to the mounted file systems.
Answer: D
Explanation:
Explanation
NFS export options enable you to create more granular access control than is possible using just security list rules to limit VCN access. You can use NFS export options to specify access levels for IP addresses or CIDR blocks connecting to file systems through exports in a mount target. Access can be restricted so that each client's file system is inaccessible and invisible to the other, providing better security controls in multi-tenant environments.
Using NFS export option access controls, you can limit clients' ability to connect to the file system and view or write data. For example, if you want to allow clients to consume but not update resources in your file system, you can set access to Read Only. You can also reduce client root access to your file systems and map specified User IDs (UIDs) and Group IDs (GIDs) to an anonymous UID/GID of your choice. For more information about how NFS export options work with other security layers
