• Question 184:

  You are about to deploy an e-business application on Oracle Cloud Infrastructure and one of the requirements is to use a shared file system that supports the NFS protocol. Which storage service would meet this requirement?

  A. object storage
  B. block volume
  C. data transfer appliance
  D. file storage
  D. file storage

  ---

  Use the File Storage service when your application or workload includes big data and analytics, media processing, or content management, and you require Portable Operating System Interface (POSIX)-compliant file system access

  semantics and concurrently accessible storage. 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 185:

  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 186:

  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 187:

  You have a working application in the US East region. The app is a 3-tier app with a database backend

  - you take regular backups of the database into OCI Object Storage in the US East region. For Business continuity; you are leveraging OCI Object Storage cross-region copy feature to copy database backups to the US West region.

  Which of the following three steps do you need to execute to meet your requirement?

  A. Write an IAM policy and authorize the Object Storage service to manage objects on your behalf
  B. Specify an existing destination bucket
  C. Specify the bucket visibility for both the source and destination buckets
  D. Provide a destination object name
  E. Provide an option to choose bulk copying of objects
  F. Choose an overwrite rule
  A. Write an IAM policy and authorize the Object Storage service to manage objects on your behalf
  B. Specify an existing destination bucket
  F. Choose an overwrite rule

  ---

  You can copy objects to other buckets in the same region and to buckets in other regions. You must have the required access to both the source and destination buckets when performing an object copy. You must also have permissions to

  manage objects in the source and destination buckets.

  Because Object Storage is a regional service, you must authorize the Object Storage service for each region carrying out copy operations on your behalf. For example, you might authorize the Object Storage service in region US East

  (Ashburn) to manage objects on your behalf. Once you authorize the Object Storage service, you can copy an object stored in a US East (Ashburn) bucket to a bucket in another region.

  You can use overwrite rules to control the copying of objects based on their entity tag (ETag) values. Specify an existing target bucket for the copy request. The copy operation does not automatically create buckets.

• Question 188:

  Which two options are available when configuring DNS resolution for your virtual cloud network? (Choose two.)

  A. Internet and custom resolver
  B. Google DNS servers
  C. custom resolver
  D. Internet and virtual cloud network (VCN) resolver
  C. custom resolver
  D. Internet and virtual cloud network (VCN) resolver

• Question 189:

  Which three actions need to be performed before attempting a data transfer service job?

  A. Obtain an available host machine which can run the dts utility on-premise with SATA or USB drives attached for the transfer job.
  B. Get access to a high-speed internet connection
  C. Data Transfer Service and Storage Service Limits should be checked and raised if required.
  D. Set up SSH access to a host on OCI to coordinate the transfer job.
  E. Create an object bucket to receive the job.
  A. Obtain an available host machine which can run the dts utility on-premise with SATA or USB drives attached for the transfer job.
  C. Data Transfer Service and Storage Service Limits should be checked and raised if required.
  E. Create an object bucket to receive the job.

• Question 190:

  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.
