Oracle 1Z0-1072-20 Online Questions & Answers

• Question 161:

  Which statement is true about the Oracle Cloud Infrastructure File Storage Service Snapshots?

  A. Snapshots are created under the root folder of file system, in a hidden directory named .snapshot
  B. Snapshots are not incremental
  C. You can restore the whole snapshot, but not the individual files
  D. It Is not possible to create snapshots from OCI console, but just the CLI
  A. Snapshots are created under the root folder of file system, in a hidden directory named .snapshot

  ---

  The File Storage service supports snapshots for data protection of your file system. Snapshots are a consistent, point-in-time view of your file systems. Snapshots are copy-on-write, and scoped to the entire file system. The File Storage

  service encrypts all file system and snapshot data at rest. You can take as many snapshots as you need.

  Data usage is metered against differentiated snapshot data. If nothing has changed within the file system since the last snapshot was taken, the new snapshot does not consume more storage Snapshots are accessible under the root

  directory of the file system at .snapshot/name. For data protection, you can use a tool that supports NFSv3 to copy your data to a different availability domain, region, file system, object storage, or remote location.

• Question 162:

  There are multiple options of migrating Oracle Databases from on-premises to Oracle Cloud Infrastructure. Which two characteristics do you need to consider when choosing a migration method? (Choose two.)

  A. On-premises database character set and application version
  B. On-premises database version and quantity of data, including indexes
  C. On-premises host operating system platform and network bandwidth
  D. On-premises connectivity using remote and local VCN peering
  B. On-premises database version and quantity of data, including indexes
  C. On-premises host operating system platform and network bandwidth

  ---

  References: https://docs.cloud.oracle.com/iaas/Content/Database/Tasks/migrating.htm Some of the characteristics and factors to consider when choosing a migration method are: On-premises database version Database service database version On-premises host operating system and version On-premises database character set Quantity of data, including indexes Data types used in the on-premises database Storage for data staging Acceptable length of system outage Network bandwidth

• Question 163:

  You have created a virtual cloud network (VCN) with three private subnets. Two of the subnets contain application servers and the third subnet contains a DB System. The application requires a shared file system so you have provisioned one using the file storage service (FSS). You also created the corresponding mount target in one of the application subnets. The VCN security lists are properly configured so that both application servers and the DB System can access the file system. The security team determines that the DB System should have read-only access to the file system. What change would you make to satisfy this requirement?

  A. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.
  B. Connect via SSH to one of the application servers where the file system has been mounted. Use the Unix command chmod to change permissions on the file system directory, allowing the database user read only access.
  C. Modify the security list associated with the subnet where the mount target resides. Change the ingress rules corresponding to the DB System subnet to be stateless.
  D. Create an instance principal for the DB System. Write an Identity and Access Management (IAM) policy that allows the instance principal read-only access to the file storage service.
  A. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.

  ---

  NFS export options enable you to create more granular access control than is possible using just security list rules to limit VCN access. You can use NFS export options to specify access levels for IP addresses or CIDR blocks connecting to file systems through exports in a mount target.

• Question 164:

  The Oracle Cloud Infrastructure Block Volume service lets you expand the size of block and boot volumes. Which three options below can you use to increase the size of your block volumes?

  A. Clone an existing volume to a new, larger volume
  B. You can only expand block volumes and not boot volumes
  C. Expand an existing volume in place with offline resizing
  D. Take a backup of your existing volume and restore from the volume backup to a larger volume
  E. Expand an existing volume in place with online resizing
  A. Clone an existing volume to a new, larger volume
  C. Expand an existing volume in place with offline resizing
  D. Take a backup of your existing volume and restore from the volume backup to a larger volume

  ---

  The Oracle Cloud Infrastructure Block Volume service lets you expand the size of block volumes and boot volumes. You have three options to increase the size of your volumes:

  Expand an existing volume in place with offline resizing. See Resizing a Volume Using the Console for the steps to do this.

  Restore from a volume backup to a larger volume. See Restoring a Backup to a New Volume and Restoring a Boot Volume.

  Clone an existing volume to a new, larger volume. See Cloning a Volume and Cloning a Boot Volume.

• Question 165:

  With regard to Oracle Cloud Infrastructure Load Balancing service, which two actions will occur when a backend server that is registered with a backend set is marked to drain connections?

  A. All existing connections to this backend sever will be immediately closed.
  B. Requests to this backend server are redirected to a user-defined error page.
  C. All new connections to this backend server are disallowed.
  D. Connections to this backend server will remain open until all in-flight requests are completed.
  E. All connections to this backend server are forcibly closed after a timeout period.
  C. All new connections to this backend server are disallowed.
  D. Connections to this backend server will remain open until all in-flight requests are completed.

• Question 166:

  Which two options are valid for loading data directly into Autonomous Data Warehouse (ADW)? (Choose two.)

  A. Data Integrator
  B. Data Pump
  C. Data Transfer Service
  D. SQL *Loader
  B. Data Pump
  D. SQL *Loader

• Question 167:

  Which storage would you use if your big data workload requires shared access and an NFS based interface?

  A. File Storage
  B. Storage Software Cloud Appliance
  C. Object Storage
  D. Archive Storage
  E. Block Volume
  A. File Storage

  https://docs.cloud.oracle.com/iaas/Content/File/Concepts/filestorageoverview.htm The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases,

  including the following:

  General Purpose File Storage: Access to an unlimited pool of file systems to manage growth of structured and unstructured data.

  Big Data and Analytics: Run analytic workloads and use shared file systems to store persistent data. Lift and Shift of Enterprise Applications: Migrate existing Oracle applications that need NFS storage, such as Oracle E-Business Suite and

  PeopleSoft.

  Databases and Transactional Applications: Run test and development workloads with Oracle, MySQL, or other databases.

  Backups, Business Continuity, and Disaster Recovery: Host a secondary copy of relevant file systems from on premises to the cloud for backup and disaster recovery purposes. MicroServices and Docker: Deliver stateful persistence for

  containers. Easily scale as your container- based environments grow.

• Question 168:

  You are responsible for setting up access for all the cloud users of a large enterprise. You log in to the Phoenix region and start creating users and policies. You then realize that some users might be creating resources in the Ashburn region. Which step should you perform to enable those users?

  A. You can assign a region to each of the users at the time of creation.
  B. IAM users are global and non-admin users can add resources to any region by default.
  C. You need to log in to each region separately to create users for that particular region.
