An online registration system Is currently hosted on one large Oracle Cloud Infrastructure (OCT) Bare metal compute Instance with attached block volume to store of the users' data. The registration system accepts the Information from the user, Including documents and photos then performs automated verification and processing to check it the user is eligible for registration.
The registration system becomes unavailable at tunes 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 use data being uploaded by the users.
Which Is the most effective option to achieve a highly scalable solution?

• A.Change your architecture to use an OCI Object Storage standard tier bucket, replace the single bare metal instance with a Oracle Streaming Service (OSS) to ingest the Incoming requests and distribute the tasks to a group of compute Instances with Auto Scaling
• B.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.
• C.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.
• D.Attach more Block volumes as the data volume increase, 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.

You have deployed a multi-tier application with multiple compute instances in Oracle Cloud Infrastructure.
You want to back up these volumes and have decided to use Volume Group's feature. The Block volume and Compute instances exist in different compartments within your tenancy.
Periodically. a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.
What could be the cause?

• A.You are exceeding your volume group backup quota configured.
• B.You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.
• C.Compute instance with multiple block volumes attached cannot move when a compartment is moved.
• D.The Identity and Access Management policy allowing backup failed to move when the compartment was moved.

As a part of migration exercise for an existing on premises application to Oracle Cloud Infrastructure (OCT), yon ore required to transfer a 7 TB file to OCI Object Storage. You have decided to upload functionality of Object Storage.
Which two statements are true?

• A.Active multipart upload can be checked by listing all parts that have been uploaded, however It Is not possible to list information for individual object part in an active multipart upload
• B.It is possible to spill this fileInto multiple parts using the APIs provided by Object Storage.
• C.It is possible to split this file into multiple parts using rclone tool provided by Object Storage.
• D.After initiating a multipart upload by making a CreateMultlPartUpload RESI API Call, the upload remains active until you explicitly commit it or abort.
• E.Contiguous numbers need to be assigned for each part so that Object Storage constructs the object by ordering, part numbers in ascending order

Your Oracle database is deployed on-premises and has produced 100 TB database backup locally. You have a disaster recovery plan that requires you to create redundant database backups in Oracle Cloud Infrastructure (OCI).
Once the initial backup is completed, the backup must be available for retrieval in less than 30 minutes to support the Recovery Time Objective (RTO) of your solution.
Which is the most cost effective option to meet these requirements?

• A.Use OCI Storage Gateway to transfer the backup files to OCI Object Storage Standard tier as the final destination.
• B.Setup an IPsec VPNConnect between on-premises data center and OCI. Then to use OCI CLI command to upload database backups to OCI Object Storage Archive tier as the final destination.
• C.Setup a FastConnect connection between on-premises data center and OCI. Then to use OCI CLI command to upload database backups to OCI Object Storage Standard tier as the final destination.
• D.Use OCI Storage Gateway to transfer the backup files to OCI Object Storage Archive tier as the final destination.

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?

• A.Option B provides higher level of throughput, but lower level of IOPS performance.
• B.Option B provides better IOPS and throughput performance.
• C.Option A provides better IOPS, but lower throughput performance.
• D.Both options provide the same number of IOPS and throughput performance.
