You have deployed a web application targeting a global audience across multiple Oracle Cloud Infrastructure (OCI) regions. You decide to use Traffic Management Geo-Location based Steering Policy to serve web requests to users from the region closets to the user. Within each region you have deployed a public load balancer with 4 servers in a backend set. During a DR test disable all web servers in one of the regions however, traffic Management does not automatically direct all users to the other region. Which two are possible causes? You did not correctly setup the Load Balancer HTTP health check policy associated with me backend set One of the two working web servers In the other region did not pass Its HTTP health check You did not setup a Route I able associated with load Balancer's subnet You did not setup an HTTP Health Check associated with Load Balancer public IP in the disabled region. Rather than using Geo-Location based Steering Policy, you should use Failover Policy Type to serve traffic.
You are creating an Oracle Cloud Infrastructure Dynamic Group. To determine the members of this group you are defining a set of matching rules. Which of the following are the supported variables to define conditions in the matching rules? (Choose Two) instance.compartment.id -the OCID of the compartment where the instance resides. instance.tenancy.id -the OCID of the tenancy where the instance resides. tag <tagnamespace>, <tagkey>value -the tag namespace and tag key. iam.policy.id - the OCID of the 1AM policy to apply to the group.
You are building a demo for a customer that showcases Oracle Cloud Infrastructure (OCI) Events service and Oracle Functions. You plan to create an event every time an image is uploaded to an OCI Object Storage bucket. You have also created a function that is listening to the event and processes the image for face recognition. Choose the two actions from below that are NOT required to run the demo successfully. The function must be deployed only to Oracle Kubernetes Engine (OKE). You have to enable Object Storage buckets to emit events for state changes. You must deploy the function that does facial recognition for the demo to work. Creating an event rule is not permitted for OCI Object storage. You must specify an action type while creating an Event service and specify the function you want to trigger.
An online gaming application is deployed to multiple Availability Domains in the Oracle Cloud Infrastructure (OCI) us-ashburn-1 region. Considering the high volume of traffic that the gaming application handles, the company has hired you to ensure that the data stored by the application is scalable, highly available, and disaster resilient. In the event of failure, the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) must be less than 2 hours. Which Disaster Recovery strategy should be used to achieve the RTO and RPO requirements in the event of a system failure? Configure hourly block volumes backups using the OCI Command Line Interface (CLI). Create a user defined backup policy with a schedule of generating daily backups for block volumes. Configure hourly block volumes backups through the OCI Storage Gateway service. Create a user defined backup policy with a schedule of generating hourly backups for block volumes.
A fast growing E-commerce company has deployed their online shopping application on Oracle Cloud Infrastructure. The application was deployed on compute instances with Autoscaling configuration for application servers fronted by a load balancer and OCI Autonomous Transaction Processing (ATP) in the backend. In order to promote their e-commerce platform 50% discount was announced on all the products for a limited period. During the day 1 of promotional period it was observed that the application is running slow and company's hotline is flooded with complaints. What could be two possible reasons for this situation? The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation. As part of Autoscaling, the load balancer shape has dynamically changed to a larger shape to handle more incoming traffic and the system was slow for a short time during this change. The health check on some of the backend servers has failed and the load balancer was rebooting these servers. Autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room for scaling further.
You are tasked with backing up your data using Oracle Cloud Infrastructure Block Volume service. When you are finalizing your block volume backup schedule, which of the following two are valid considerations for your backup plan? (Choose Two) Number of stored backups: How many backups you need to keep available and the deletion schedule for those you no longer need. Governance: Tagging of backups so you can capture backup related API calls through the Audit service. Frequency: How often you want to back up your data. Location: Determine the Object Store Bucket where the backups will be stored. Encryption: Whether to use your own key to encrypt your volume backups.
As a solution architect, you are designing a web application to be deployed across multiple Oracle Cloud Infrastructures (OCI) regions for a global audience.

Trigger a notification when a function completes its execution.
Which of the following is NOT a good use case for the Oracle Cloud Infrastructure (OCI) Streaming service? Meeting compliance requirements for data to remain unchanged over a long time, so that it can be retrieved for audit purposes. Messaging with a pull-based communication model and the ability to feed multiple consumers with the same data independently. Ingesting metric and log data to help make critical operational data more quickly available for indexing, analysis, and visualization. Providing a unified entry point for cloud components to report their life cycle events for audit, accounting, and related activities.
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? 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.

Web Application Firewall policy using access control rules Deny rules in Virtual Cloud Network Security Group for the specific set of IP addresses. Delete Internet Gateway from Virtual Cloud Network. Deny rules in Virtual Cloud Network Security Lists for the specific set of IP addresses.
Which of the following is NOT a good use case for the volume backup feature of the Oracle Cloud Infrastructure Block Volume service? Support business continuity requirements of reducing the risk of outages or data mutation over time. Meet compliance and regulatory requirements for data to remain unchanged over time, so that it can be retrieved for audit purposes. Rapidly duplicate an environment in seconds to test configuration changes without impacting your production environment. Retain a copy of data in a volume, so that you can duplicate an environment later or preserve the data for future use.
Which of the below options is true regarding Oracle Cloud Infrastructure's load balancing service? You can dynamically change the load balancer shape to handle more incoming traffic. The public load balancer applies a floating public IP address to the primary load balancer. When you create a private load balancer, the service requires 2 or more subnets to host both the primary and standby load balancers. A public load balancer is Availability Domain specific in scope.
You 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.
An organization has its mission critical application consisting of multiple application servers and databases running inside Virtual Cloud Network (VCN) in uk-london-1 region. Their solution architect wants to further strengthen their architecture by planning for Disaster Recovery (DR) in eu-frankfurt-1 region. Which two solutions should their architect keep in mind while designing for DR? It is not possible to use Active Data Guard to synchronize a database in uk-london-1 region to equivalent database in eu-frankfurt-1 region. Load balancer will automatically distribute traffic between both the regions. A remote VCN peering connection is required to establish secure and reliable connectivity between different VCNs created in uk-london-1 and eu-frankfurt-1 region. rsync utility can be used to asynchronously copy file systems or snapshot data to another region. The RTO is the acceptable timeframe of lost data that application can tolerate.
You 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 better IOPS and throughput performance. 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.
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? Create a volume group, add the block volume and boot volume and then run the volume group backup. Before creating a backup, save your application data and detach the block volume. Create a backup, detach the block volume and save your application data. Use the block volume clone feature to save cost and speed up the backup process.

You are working as a solution architect for a customer in Frankfurt, which uses multiple compute instance VMs spread among three Availability Domains in the Oracle Cloud Infrastructure (OCI) eu-frankfurt-1 region. The compute instances do not have public IP addresses and are running in private subnets inside a Virtual Cloud Network (VCN). You have set up OCI Autoscaling feature for the compute instances, but find out that instances cannot be auto scaled. You have enabled monitoring on the instances. What could be wrong in this situation? Autoscaling only works for instances with public IP addresses. Autoscaling only works with single availability domains. You need to assign a reserved public IP address to the compute instances. You need to set up a Service Gateway to send metrics to the OCI Monitoring service.
You are trying to troubleshoot the configuration of your Oracle Cloud Infrastructure (OCI) Load Balancing service. You have a backend HTTP service for which you have created a backend set in the load balancer. You have configured health checks for the backend set. Although the health checks appear good, customers sometimes experience transaction failures. Which of the following options will definitely lead to this problem? You are NOT using regional subnets in your Virtual Cloud Network. With Availability Domain (AD) specific subnet. the compute instances of the backend service running in the subnet have issues when the AD is down. You are using OCI Domain Name System. You have misconfigured the 'A' record with the wrong IP address leading to requests not getting routed correctly. You are using iSCI for block volume attachment to the compute instances in your backed HTTP service. TCP/IP configuration of your block volume attachment is not configured correctly, leading to issues in your backend service. You are running a TCP-level health check against your HTTP service. The TCP handshake can succeed and indicate that the service is up even when the HTTP service has issues.
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? Use locally attached NVMe instances and configure RAID 0 replication between servers. 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. Implement a single instance and install an NFS server, configure and create an NFS share, and mount this as /audit on the application instances. Store the data on Oracle Object Storage mounted at the /audit mount point on all the Linux instances using the default mount options.
You are a solution architect working with a startup that has decided to move their workload to Oracle Cloud Infrastructure. Since their workload is small, upon architecting, you decide its sufficient to use 8 compute instances to run their workload. The company wants to use a common storage for their instances. So, you propose the idea of attaching a block volume to multiple instances to provide a common storage. Which of the below option is NOT true for such a solution? If the block volume is already attached to an instance as read/write non-shareable you can't attach it to another instance until you detach it from the first instance. You can delete a block volume from one instance without detaching it from all other instances there by keeping other instance's storage intact. Block volumes attached as read-only are configured as shareable by default. Once you attach a block volume to an instance as read-only, it can only be attached to other instances as read-only.
Which of the following features is NOT supported by Oracle Cloud Infrastructure Multi-factor authentication (MFA)? Only the user can enable MFA for their own account. Members of the Administrators group can disable MFA for other users. Users can disable MFA for their own accounts. Members of the Administrators group can enable MFA for other users.
A cloud consultant is working on implementation project on OCI. As part of the compliance requirements, the objects placed in object storage should be automatically archived first and then deleted. He is testing a Lifecycle Policy on Object Storage and created a policy as below: [ { "name": "Archive_doc", "action": "ARCHIVE", "objectNameFilter": { "inclusionPrefixes": "doc"] }, "timeAmount": 5, "timeunit": "DAYS", "isEnabled": true }, { "name": "Delete_doc", "action": "DELETE", "objectNameFilter": "inclusionPrefixes": [ "doc"] 1."timeAmount": 5, "timeunit": "DAYS", "isEnabled": true } What will happen after this policy is applied? All objects with names starting with "doc" will be deleted after 5 days of object creation All the objects having file extension ".doc" will be archived for 5 days and will be deleted 10 days after object creation All the objects having file extension ".doc" will be archived 5 days after object creation All the objects with names starting with "doc" will be archived 5 days after object creation and will be deleted 5 days after archival.
Your customer has gone through a recent departmental re structure. As part of this change, they are organizing their Oracle Cloud Infrastructure (OCI) compartment structure to align with the company's new organizational structure. They have made the following change: Compartment x Is moved, and its parent compartment is now compartment c. Policy defined in compartment A: Allow group networkadmins to manage subnets in compartment X Policy defined in root compartment: Allow group admins to read subnets in compartment Finance:A:X After the compartment move, which action will provide users of group networkadmins and admins with similar privileges as before the move? Define a policy in Compartment C as follows: Allow group network admins to manage subnets in compartment X. No change in any policy statement is required as compartments move automatically moves alt the policy statements associated with compartments as well. Define a policy in compartment C as follows: Allow group admins to read subnets in compartment HR:C:X Define a policy in compartment HR as follows: Allow group network admins to manage subnets in compartment X. Define a policy in compartment C as follows Allow group admins to read subnets in compartment HR:C:X.
You have multiple IAM users who launch different types of compute Instances and block volumes every day. As a result, your Oracle cloud Infrastructure (OCF) tenancy quickly hit the service limit and you can no longer create any new instances. As you are cleaning up environment, you notice that the majority of the Instances and block volumes are untagged. Therefore, It is difficult to pinpoint the owner of these resources verify if they are safe to terminate. Because of this, your company has issued a new mandate, which requires adding compute instances. Which option is the simplest way to implement this new requirement? Create a policy to automatically tag a resource with the user name. Create a policy using 1AM requiring users to tag specific resources. This will allow a user to launch compute instances on\y if certain tags were defined. Create tag variables to automatically tag a resource with the user name. Create a default tag for each compartment, which ensure that appropriate tags are applied at resource creation Create tag variables for each compartment to automatically tag a resource with the user name.

Increase the TTL of the DNS records after the switch. Reduce the TTL of the DNS records before the switch.
An eCommerce company is running on Oracle Cloud Infrastructure (OCI) and many compute instances remain unused for the most part of the year except during Black Friday and Christmas. You suggest them to use OCI's Autoscaling feature and present them a slide to showcase the features of Autoscaling. Which option below is inaccurate in your presentation to the customer? A cooldown period between Autoscaling events lets the system stabilize at the updated level. When an instance pool scales in, instances are terminated in this order: the number of instances is balanced across Availability Domains, and then balanced across Fault Domains. Finally, within a Fault Domain, the newest instance is terminated first. Autoscaling relies on performance metrics such as CPU utilization that are collected by OCI Monitoring service to trigger an Autoscaling event. Autoscaling requires an instance pool as a pre-requisite so that it can automatically adjust the number of compute instances in an instance pool.
You have to migrate your application to Oracle Cloud Infrastructure (OCI). The database is constantly being updated and needs to be online without interruptions. How can you transition the database to OCI without interrupting its use? It is impossible to migrate without interruption. Use an on-premises database with two-way synchronization to a cloud-based database and allow clients to connect to either databases. Use an on-premises database with one-way synchronization to a cloud-based database and allow clients to connect only to the cloud database. Use an on-premises database with one-way synchronization to a cloud-based database and allow clients to connect only to the on-premises database until it is synchronized.
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.<br />Which of the following is a NOT a true statement? Before you create a custom image of an instance, you must disconnect all iSCSI attachments and remove all iscsid node configurations from the instance. Editing custom Windows images is not supported due to hardware differences between shapes. Custom images do not include the data from any attached block volumes. You can create additional custom images of an instance while the instance is engaged in the image creation process.
