 OCI Traffic Management GeoLocation steering policy
QUESTION 41You 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?
 Use OCI CLI to call “GetVnic” operation to find out the parent resource of the VNIC
 Copy and Paste OCID of the VNIC in the search box of the OCI Console to find out the parent resource of the VNIC
 Use OCI CLI to delete the VNIC first and then delete the subnet
 Use OCI CLI to delete the subnet using –force option
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_OCIDQUESTION 42Your customer has gone through a recent reorganization. As part of this change, they are organizing their Oracle Cloud Infrastructure (OCI) compartment structure to align with the company’s new organizational structure. (Refer to the exhibit)They have made the following change:Compartment A is moved, and its new parent compartment is compartment Dev.Policy defined in compartment A: Allow group G1 to manage instance-family in compartment A Policy defined in root compartment: Allow group admins to manage instance-family in compartment Ops: Test: A After the compartment move, which action will provide users of group G1 and admins with similar privileges as before the move?
 Define the following policy in compartment Dev:Allow group G1 to manage instance-family in compartment A
 Define the following policies in compartment Dev:Allow group G1 to manage instance-family in compartment AAllow group admins to manage instance-family in compartment Ops: Dev: A
 Define the following policy in compartment: Dev:Allow group admins to manage instance-family in compartment Ops: Dev: A
 Mo change in any policy statement is required as all the policies associated with a compartment being moved is automatically updated
QUESTION 43You are working with a customer who needs to attach an Oracle Cloud Infrastructure (OCI) block volume to a VM instance with read/write access type. The customer wants to know if the number of IOPS and throughput performance differs between the following two choices:* Option A: attach a single 1 TB block volume to the VM instance* Option B: attach two separate 500 GB block volumes In a RAID 0 array configuration to the VM instance You can assume that the customer is using iSCSI attachment type to attach the volumes to the instance. In addition, you can assume 1 MB block size for throughput and 4 KB block size for IOPS consideration.How should you respond to the customer?
 Option B provides higher level of throughput, but lower level of IOPS performance.
 Both options provide the same number of IOPS and throughput performance.
 Option A provides better IOPS, but lower throughput performance.
 Option B provides better IOPS and throughput performance.
QUESTION 44A company has an urgent requirement to migrate 300 TB of data to Oracle Cloud Infrastructure (OCI) In two weeks. Their data center has been recently struck by a massive hurricane and the building has been badly damaged, although still operational. They have a 100 Mbps Internet line but the connection is Intermittent due to the damages caused to the electrical grid in this scenario, what is the most effective service to use to migrate the data to OCI given the time constraints?
 Setup a OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI using OCI Storage Gateway Cloud Sync tool.
 Setup a hybrid network by launching aIGbpsFastConnect virtual circuit between your data center and OCI. Use OCI Object storage multipart upload tool to automate the migration of your data to OCI.
 Use multiple OCI Data Transfer Appliances to transfer data to OCI.

https://docs.oracle.com/en/solutions/learn-azure-oci-interconnect/index.html#GUID-FBE38C70-A4CF-40C5-A37A-121241D21199QUESTION 49You 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?
 Use Oracle Data Guard to keep on premises database always active during migration
 Retain changes to Oracle shipped privileges, stored procedures or views In the on-premises databases.
 Use Oracle GoldenGate replication to keep on premises database online during migration.
 Convert on-premises databases to PDB, upgrade to 19c, and encrypt Migration.
 Retain all legacy structures and unsupported features (e.g. taw U>Bs) In the onuses databases for migration.
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 migrationQUESTION 50Your 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?
 Use stateless Security List rule to restrict access from known IP addresses only.
 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.
 Use ‘Export option’ feature of FSS to restrict access to the mounted file systems.
 Create and configure OCI Web Application Firewall service with built in DNS based intelligent routing.
ExplanationNFS 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 layersQUESTION 51A retailer bank is currently hosting their mission critical customer application on-premises. The application has a standard 3 tier architecture -4 application servers process the incoming traffic and store application data in an Oracle Exadata Database Server.

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?
 Configure hourly block volumes backups through the Storage Gateway service.
 Configure hourly block volumes backups using the Oracle Cloud Infrastructure (OCI) Command Line Interface (CLI)
 Store hourly block volumes backup to NVMe device under a compute instance and generate a custom Image every 5 minutes.
 Configure your application to use synchronous master slave data replication between Availability Domains.
You can use the CLI, REST APIs, or the SDKs to automate, script, and manage volume backups and their lifecycle.Planning Your BackupThe 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 storeQUESTION 54A company has an application that processes confidential data. The data is currently stored in an on-premises data center. A solution architect needs to move this data to Oracle Cloud Infrastructure (OCI) Object Storage and ensure data is encrypted in-transit to OCI.Which two steps should the solution architect perform to set up the most cost-effective connection between on-premises data center and OCI?

QUESTION 56You want to automate the processing of new image files to generate thumbnails. The expected rate is 10 new files every hour.Which of the following is the most cost effective option to meet this requirement in Oracle Cloud Infrastructure (OCI)?
 Upload all files to an Oracle Streaming Service (OSS) stream. Setup a cron job to invoke a function in Oracle Functions to fetch data from the stream. Invoke another function to process the image files and generate thumbnails.Store thumbnails in another OSS stream.
 Upload files to an OCI Object storage bucket. Every time a file is uploaded, an event is emitted. Write a rule to filter these events with an action to trigger a function in Oracle Functions. The function processes the image in the file and stores the thumbnails back in an Object storage bucket.
 Build a web application to ingest the files and save them to a NoSQL Database. Configure OCI Events service to trigger a notification using Oracle Notification Service (ONS). ONS invokes a custom application to process the image files to generate thumbnails. Store thumbnails in a NoSQL Database table.
 Upload files to an OCI Object storage bucket. Every time a file is uploaded, trigger an event with an action to provision a compute instance with a cloud-init script to access the file, process it and store it back in an Object storage bucket. Terminate the instance using Autoscaling policy after the processing is finished.
