  -

  Oracle Object Storage supports server-side encryption. All data stored in Oracle Object Storage is automatically encrypted

  -

  Encryption is automatically enabled for all data with no action required on the part of customers.

  -

  Oracle encrypt both the object data and the user-defined metadata associated with the object.

• Question 132:

  You are running several Linux based operating systems in your on .premises environment that you want to import to OCI as custom images. You can launch your imported images as OCI compute Virtual machines. Which two modes below can be used to launch these imported Linux VMs?

  A. Native
  B. Mixed
  C. Paravirtualized
  D. Emulated
  C. Paravirtualized
  D. Emulated

  ---

  You can use the Console or API to import exported images from Object Storage. To import an image, you need read access to the Object Storage object containing the image.

  during the Import you can select the Launch mode:

  For custom images where the image format is .oci, Oracle Cloud Infrastructure selects the applicable launch mode based on the launch mode for the source image. For custom images exported from Oracle Cloud Infrastructure where the

  image type is QCOW2, select Native Mode.

  To import other custom images select Paravirtualized Mode or Emulated Mode. For more information, see Bring Your Own Image (BYOI).

  

• Question 133:

  For what business need should you use Database Cloud Service (DBCS) instead of Oracle database on a compute instance?

  A. to bring your own license on a compute service
  B. to lower license and infrastructure cost
  C. to implement Oracle RAC for high availability
  D. to build an Oracle database on a compute service
  C. to implement Oracle RAC for high availability

• Question 134:

  Which two tools would you use to manage Database Cloud Service (DBCS)? (Choose two.)

  A. psql
  B. Oracle Swingbench
  C. SQL Developer
  D. Oracle Enterprise Manager
  C. SQL Developer
  D. Oracle Enterprise Manager

• Question 135:

  Which two statements are true about Autonomous Data Warehouse (ADW) backup?

  A. You can perform manual backups to OCI object storage in addition to automated backups available on ADW
  B. You can backup ADW database only to a standard bucket type in OCI object storage
  C. Oracle Cloud Infrastructure (OCI) recommends backing up ADW databases manually to on- premises storage devices
  D. You must backup ADW database to object storage bucket named ADW_backup
  A. You can perform manual backups to OCI object storage in addition to automated backups available on ADW
  B. You can backup ADW database only to a standard bucket type in OCI object storage

  ---

  Autonomous Database automatically backs up your database for you.In addition to automatic backups Autonomous Database also allows you take manual backups to your Oracle Cloud Infrastructure Object Storage. for example if you want

  to take a backup before a major change to make restore and recovery faster.

  Also, Manual backups are only supported with buckets created in the standard storage tier if you provision an Autonomous Data Warehouse instance named ADWC1, the bucket name should be backup_adwc1 (the bucket name is

  lowercase)

• Question 136:

  Which statement Is true about Data Guard implementation in Oracle Cloud Infrastructure (OCI) bare metal and virtual machine database systems?

  A. Primary and standby databases must be in the same OCI region.
  B. Both database systems must be in the same compartment.
  C. Database systems need not be the same shape type (e.g, primary database can be a virtual machine, and standby database a bare metal shape, and vice versa).
  D. Primary and standby database versions and editions need not be Identical.
  B. Both database systems must be in the same compartment.

• Question 137:

  You are the Cloud Architect of a company, and are designing a solution on Oracle Cloud Infrastructure where you want to have all your compute instances resistant to hardware failure. Which two are recommended best practices to achieve the requirement on Oracle Cloud Infrastructure? (Choose two.)

  A. Create a custom image of your system drive each time you change the image.
  B. Attach block volumes from different Availability Domains to compute instances in different Availability Domains for high availability.
  C. Design your system with redundant compute modes in different Availability Domains to support the failover capability.
  D. Create backups of your block volumes that are associated with compute instances in different regions.
  A. Create a custom image of your system drive each time you change the image.
  C. Design your system with redundant compute modes in different Availability Domains to support the failover capability.

  Oracle Cloud Infrastructure runs on Oracle's high-quality Sun servers. However, any hardware can experience a failure. Follow industry-wide hardware failure best practices to ensure the resilience of your solution. Some best practices

  include:

  Design your system with redundant compute nodes in different availability domains to support fail- over capability.

  Create a custom image of your system drive each time you change the image. Back up your data drives, or sync to spare drives, regularly. If you experience a hardware failure and have followed these practices, you can terminate the failed

  instance, launch your custom image to create a new instance, and then apply the backup data.

• Question 138:

  Which two resources are availability domain constructs? (Choose two.)

  A. VCN
  B. Groups
  C. Block Volume
  D. Compute Instance
  E. Object Storage
  C. Block Volume
  D. Compute Instance

• Question 139:

  Which three load-balancing policies can be used with a back end set? (Choose three.)

  A. Throughput
  B. IP Hash
  C. Weighted Round Robin
  D. CPU Utilization
  E. Least Connections
  B. IP Hash
  C. Weighted Round Robin
  E. Least Connections

  ---

  References: After you create a load balancer, you can apply policies to control traffic distribution to your backend servers. The Load Balancing service supports three primary policy types: Round Robin Least Connections IP Hash

• Question 140:

  Which two identity providers can your administrator federate with Oracle Cloud Infrastructure? (Choose two.)

  A. Microsoft Active Directory
  B. Oracle Identity Cloud Services
  C. AWS Directory Services
  D. Google Directory Federation Services
  A. Microsoft Active Directory
  B. Oracle Identity Cloud Services

  ---

  References:

  Oracle Cloud Infrastructure supports federation with Oracle Identity Cloud Service and Microsoft Active Directory (via Active Directory Federation Services (AD FS)), and any identity provider that supports the Security Assertion Markup

  Language (SAML) 2.0 protocol.
