Oracle Cloud Infrastructure 2020 Architect Professional 4

An online registration system is currently hosted on one large Oracle Cloud Infrastructure (OCI) Bare metal compute instance with attached block volumes to store all of the users' data. The registration system accepts the information from the user, including documents and photos and then performs automated verification and processing to check is the user is eligible for registration. The registration system becomes unavailable at times, when there is a surge of users using the system. The existing architecture needs improvement as it takes a long time for the system to complete the processing and the attached block volumes are not large enough to store the ever growing data being uploaded by the users. Which is the most effective option to achieve a highly scalable solution? (Choose the best answer.). Upgrade your architecture to use a pool of Bare metal servers and configure them to use their local SSDs for faster data access. Set up Oracle Streaming Service (OSS) to distribute the tasks to the pool of Bare metal instances with Auto Scaling to dynamically increase or decrease the pool of compute instances depending on the length of the Streaming queue. Change your architecture to use an OCI Object Storage standard tier bucket; replace the single bare metal instance with an Oracle Streaming Service (OSS) to ingest the incoming requests and distribute the tasks to a group of compute instances with Auto Scaling. Attach more Block volumes as the data volume increases, use Oracle Notification Service (ONS) to distribute tasks to a pool of compute instances working in parallel, and Auto Scaling to dynamically size the pool of instances depending on the number of notifications received from the Notification Service. Use Resource Manager stacks to replicate your architecture to another region. Upgrade your architecture to use more Block volumes as the data volume increases. Replace the single bare metal instance with a group of compute instances with Auto Scaling to dynamically increase or decrease the compute instance pools depending on the traffic.

You are designing the network infrastructure for two application servers: appserver-1 and appserver-2 running in two different subnets inside the same Virtual Cloud Network (VCN) in Oracle Cloud Infrastructure (OCI). You have a requirement where your end users will access appserver-1 from the internet and appserver-2 from the on-premises network. The on-premises network is connected to your VCN over a FastConnect virtual circuit. How should you design your routing configuration to meet these requirements? (Choose the best answer.). Configure a single routing table (Route Table-1) that has two sets of rules: one that has route to internet via the Internet Gateway and another that propagates specific routes for the on-premise network via Dynamic Routing Gateway (DRG). Associate the routing table with the VCN. Configure two routing tables: Route Table-1 that has a route to internet via the Internet gateway. Associate this route table to the subnet containing appserver- 1. Route Table-2 that propagate specific routes for the on-premises network via the Dynamic Routing Gateway (DRG). Associate this route table to subnet containing appserver-2. Configure a single routing table (Route Table-1) that has two sets of rules. One that has route to internet via the Internet Gateway and another that propagates specific routes for the on-premise network via the Dynamic Routing Gateway. Associate the routing table with all the VCN subnets. Configure two routing tables (Route Table-1 & Route Table-2) that have rule to route all traffic via the Dynamic Routing Gateway (DRG). Associate the two routing tables with all the VCN subnets.

Your customer recently provisioned a 1-Gbps FastConnect connection in ap-tokyo-1 region of Oracle Cloud Infrastructure (OCI). They will use this to connect to one Virtual Cloud Network (VCN) in their production OCI tenancy compartment and another VCN in their development OCI tenancy. How should you configure the connectivity between on-premises and the two VCNs in OCI using the single FastConnect connection? (Choose the best answer.). Provision a Dynamic Routing Gateway (DRG) and create a private virtual circuit for the FastConnect connection. Create one additional route table in your production VCN that includes two routes rules. One with a destination of the on-premises network using the DRG, and a second with a destination of the development VCN, also using the DRG. Create two private virtual circuits on the FastConnect link. Create two Dynamic Routing Gateways, one for each VCNs. Attach the virtual circuits to the dynamic routing gateways. Create a hub-VCN that uses DRG to communicate with the on-premises network over FastConnect. Connect the hub-VCN to the production VCN spoke and with development VCN spoke, each peered via their respective Local Peering Gateway (LPG). Create a single private virtual circuit over FastConnect and attach Fastconnect to either of the VCN's DRG. Use Remote Peering to peer production and development VCNs.

All three Data Guard configurations 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 RPO without causing any data loss? (Choose the best answer.). Configure "Maximum Availability" mode in SYNC mode between two availability domains (same region), and use the Maximum Availability mode in ASYNC mode between two regions. Configure "Maximum Protection" mode which provides zero data loss if the primary database fails. Configure "Maximum Scalability" mode which provides the highest level of scalability without compromising the availability of the primary database. 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.

As a part of a migration exercise for an existing on-premises application to Oracle Cloud Infrastructure (OCI), you are required to transfer a 7 TB file to OCI Object Storage. You have decided to upload it using the multipart upload functionality of Object Storage. Which two statements are true? (Choose two.). It is possible to split this file into multiple parts using rclone tool provided by Object Storage. Contiguous numbers need to be assigned for each part so that Object Storage constructs the object by ordering part numbers in ascending order. After initiating a multipart upload by making a CreateMultiPartUpload REST API Call, the upload remains active until you explicitly commit it or about it. It is possible to split this file into multiple parts using the APIs provided by Object Storage. Active multipart upload can be checked by listing all parts that have been uploaded, however it is not possible to list information for an individual object part in an active multipart upload.

You are advising the database administrator responsible for managing non-production environment for Oracle Autonomous Database running on Oracle Cloud Infrastructure. You need to help the database administrator ensure that the non-production environments have a copy of the current data from the production environment in a manner that is most time-efficient. Which method should you recommend? (Choose the best answer.). Take a full database backup of the production Autonomous database and create the non-production database from it. Create a metadata clone of the production Autonomous Database and create the non-production database from it. Create a full clone of the production Autonomous Database and create the non-production database from it. Take a Data Pump export of the production Autonomous database and import into the non-production database.

Your customer went 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 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 you move the compartment, which two IAM policies would be required to ensure both groups retain the same permissions to compartment X that they had before? (Choose two.). Define a policy in the root compartment as follows: Allow group admins to manage subnets in compartment Finance:A:X. Define a policy in compartment HR as follows: Allow group networkadmins to manage subnets in compartment C:X. Define a policy in the root compartment as follows: Allow group admins to read subnets in compartment HR:C:X. Define a policy in compartment C as follows: Allow group networkadmins to read subnets in compartment X.

A 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? (Choose the best answer.). Use multiple OCI Data Transfer Appliances to transfer data to OCI. Setup an OCI Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI. Setup a hybrid network by launching a 1Gbps FastConnect virtual circuit between your data center and OCI. Use OCI Object Storage multipart upload tool to automate the migration of your data to OCI. Setup an 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. Upload the data to OCI using OCI Object Storage multipart upload tool.

You are working as a solutions architect for an online retail store in Frankfurt which uses multiple compute instance VMs spread among three availability domains in the eu-frankfurt-1 region. You noticed the website is having very high traffic, so you enabled autoscaling to suffice the needs of your application but, you observed that one of the availability domains is not receiving any traffic. What could be wrong in this situation? (Choose the best answer.). Autoscaling only works with single availability domains. You forgot to attach a load balancer to your instance pool configuration. You have to manually add all three availability domains to your load balancer configuration. Autoscaling is using an Instance Pool configured to create instances in two availability Domains. Autoscaling can be enabled for multiple availability domains only in uk-london-1 region.
