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?

• A.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.
• B.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.
• C.Use multiple OCI Data Transfer Appliances to transfer data to OCI.
• D.Upload the data to OCI using OCI Object Storage multipart upload tool.
• E.Storage Gateway to connect your data center and your VCN. Once the connection has been established, upload all data to OCI.

Your company will soon start moving critical systems Into Oracle Cloud Infrastructure (OCI) platform. These systems will reside in the us-phoenix-1and us-ashburn 1 regions. As part of the migration planning, you are reviewing the company's existing security policies and written guidelines for the OCI platform usage within the company. you have to work with the company managed key.
Which two options ensure compliance with this policy?

• A.When you create a new compute instance through OCI console, you use the default options for "configure boot volume" to speed up the process to create this compute instance.
• B.When you create a new block volume through OCI console, select Encrypt using Key Management checkbox and use encryption keys generated and stored in OCI Key Management Service.
• C.When you create a new compute instance through OCI console, you use the default shape to speed up the process to create this compute instance.
• D.When you create a new OCI Object Storage bucket through OCI console, you need to choose "ENCRYPT USING CUSTOMER-MANAGED KEYS" option.
• E.You do not need to perform any additional actions because the OCI Block Volume service always encrypts all block volumes, boot volumes, and volume backups at rest by using the Advanced Encryption Standard (AES) algorithm with 256-bit encryption.

Correct Answer: B,D

Block Volume Encryption
By default all volumes and their backups are encrypted using the Oracle-provided encryption keys. Each time a volume is cloned or restored from a backup the volume is assigned a new unique encryption key.
You have the option to encrypt all of your volumes and their backups using the keys that you own and manage using the Vault service.If you do not configure a volume to use the Vault service or you later unassign a key from the volume, the Block Volume service uses the Oracle-provided encryption key instead.

This applies to both encryption at-rest and in-transit encryption.
Object Storage Encryption
Object Storage employs 256-bit Advanced Encryption Standard (AES-256) to encrypt object data on the server. Each object is encrypted with its own data encryption key. Data encryption keys are always encrypted with a master encryption key that is assigned to the bucket. Encryption is enabled by default and cannot be turned off. By default, Oracle manages the master encryption key. However, you can optionally configure a bucket so that it's assigned an Oracle Cloud Infrastructure Vault master encryption key that you control and rotate on your own schedule.
Encryption: Buckets are encrypted with keys managed by Oracle by default, but you can optionally encrypt the data in this bucket using your own Vault encryption key. To use Vault for your encryption needs, select Encrypt Using Customer-Managed Keys. Then, select the Vault Compartment and Vault that contain the master encryption key you want to use. Also select the Master Encryption Key Compartment and Master Encryption Key.

A data analytics company has been building Its now generation big data and analytics platform on Oracle Cloud Infrastructure (OCI). They need a storage service that provide the scale and performance that their big data applications require such as high throughput to compute nodes with low latency file operations in addition, their data needs to be stored redundantly across multiple nodes In a single availability domain and allows concurrent connections from multiple compute Instances hosted on multiple availability domains.
Which OCI storage service can you use to meet i his requirement?

• A.Object Storage
• B.File System Storage
• C.Archive storage
• D.Block Volume

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?

• A.You need to set up a Service Gateway to send metrics to the OCI Monitoring service.
• B.Autoscaling only works for instances with public IP addresses.
• C.You need to assign a reserved public IP address to the compute instances.
• D.Autoscaling only works with single availability domains.

Which three scenarios are suitable for the Oracle Infrastructure (OCI) Autonomous transaction Processing Server less (ATP-S) deployment?

• A.well established, online auction marketplace is running an application where there is database usage 24*7 but also has peaks of activity that the hard to predict when the peaks happen, the total activities may reach 3 times the normal activity level (Correct)
• B.A small startup is deploying a new application fen eCommerce and it requires database to store customers' transactions the team b of what the load will look like since it is a new application. (Correct)
• C.A midsize company is considering migrating its legacy on premises MongoDB database to Oracle Cloud Infrastructure (OCI). The database has significantly higher workloads on weekends than weekdays
• D.A developer working on an Internal project needs to use a database during work hours but doesn't need It during nights or weekends. the project budget requires her to keep costs low. (Correct)
• E.A manufacturing company is running Oracle E-Business Suite application on premises. They are looking to move this application to OCI and they want to use a managed database offering for their database tier.
