Oracle 1Z0-1072-22 Online Questions & Answers

• Question 221:

  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 225:

  Within your tenancy you have a compute instance with a boot volume and a block volume attached. The boot volume contains the OS and the attached block volume contains the instance's important dat

  A. Logs on the boot volume have filled the boot volume and are causing issues with the OS. What should you do to resolve this situation?
  B. Stop the instance that is full. Create a manual backup of the block storage before making changes. Detach the block volume, create a new instance of the same shape with a larger custom boot volume and attach the block volume to the new instance. Configure the OS and any related application(s) to access the block volume under the same mount point as before.
  C. Create a new instance with a larger boot volume size as well a new block volume which is the same size or larger than the one attached to the full instance. rsync the state of the boot volume and the state of the block volume between the two instances.
  D. Detach the block volume from the full instance. Create a new instance of the same shape with a larger boot volume and rsync the state of the boot volume between the instances. Attach the block volume to the new instance.
  E. Create a manual backup of the block storage instance. Create a custom image of the full instance. Once that completes deploy the custom image to a new instance.
  A. Logs on the boot volume have filled the boot volume and are causing issues with the OS. What should you do to resolve this situation?

• Question 226:

  You have two NFS clients running in two different subnets within the same Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN). You have created a shared file system for the two NFS clients who want to connect to the same file system, but you want to restrict one of the clients to have READ access while the other has READ/Write access. Which OCr feature would you leverage to meet this requirement?

  A. Use VCN security rules to control access for the NFS clients
  B. Use OCI Identity Access Management to control access for the NFS clients
  C. Use File Storage NFS Export Options to control access for the NFS clients
  D. Use NFS security to control access for the NES clients
  C. Use File Storage NFS Export Options to control access for the NFS clients

  Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure, enterprise-grade network file system. You can connect to a File Storage service file system from any bare metal, virtual machine, or container instance in your Virtual Cloud Network (VCN). You can also access a file system from outside the VCN using Oracle Cloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN). EXPORT Exports control how NFS clients access file systems when they connect to a mount target. File systems are exported (made available) through mount targets. Each mount target maintains an export set which contains one or many exports. A file system must have at least one export in one mount target in order for instances to mount the file system. The information used by an export includes the file system OCID, mount target OCID, export set OCID, export path, and client export options. For more information, see Managing Mount Targets. EXPORT SET Collection of one or more exports that control what file systems the mount target exports using NFSv3 protocol and how those file systems are found using the NFS mount protocol. Each mount target has an export set. Each file system associated with the mount target has at least one export in the export set. EXPORT PATH A path that is specified when an export is created. It uniquely identifies the file system within the mount target, letting you associate up to 100 file systems to a single mount target. This path is unrelated to any path within the file system itself, or the client mount point path. EXPORT OPTIONS NFS export options are a set of parameters within the export that specify the level of access granted to NFS clients when they connect to a mount target. An NFS export options entry within an export defines access for a single IP address or CIDR block range. For more information, see Working with NFS Export Options.

• Question 227:

  What does Terraform use to create, manage, and manipulate infrastructure resources?

  A. resources
  B. provisioner
  C. instances
  D. provider
  D. provider

  ---

  The Oracle Cloud Infrastructure provider is used to interact with the many resources supported by the Oracle Cloud Infrastructure. The provider needs to be configured with credentials for the Oracle Cloud Infrastructure account.

• Question 228:

  You are managing a tier-1 OLTP application on an Autonomous Transaction Processing (ATP) database. Your business needs to run hourly batch processes on this ATP database that may consume more CPUs than what is available on the

  server.

  How can you limit these batch processes to not interfere with the OLTP transactions?

  A. Configure ATP resource management rules to change CPU/IO shares for the consumer group of batch processes.
  B. Copy OLTP data into new tables in a new table space and run batch processes against these new tables.
  C. Disable automated backup during the batch process operations.
  D. ATP is designed for OLTP workload only, you cannot run batch processes on ATP.
  A. Configure ATP resource management rules to change CPU/IO shares for the consumer group of batch processes.

  ---

  Autonomous Transaction Processing comes with predefined CPU/IO shares assigned to different consumer groups. You can modify these predefined CPU/IO shares if your workload requires different CPU/IO resource allocations.

  By default, the CPU/IO shares assigned to the consumer groups TPURGENT, TP, HIGH, MEDIUM, and LOW are 12, 8, 4, 2, and 1, respectively. The shares determine how much CPU/IO resources a consumer group can use with respect to

  the other consumer groups. With the default settings the consumer group TPURGENT will be able to use 12 times more CPU/IO resources compared to LOW, when needed. The consumer group TP will be able to use 4 times more CPU/IO

  resources compared to MEDIUM, when needed.

• Question 229:

  You have an external facing web server running in the Oracle Cloud Infrastructure (OCI) London region. You are notified that customers in North America and Australia are facing high latency while connecting to your web server. Which services are available on OCI that can help you get current latency statistics to your web server from these markets?

  A. Use DNS Zone Management service to check latency over that connection
  B. Setup an IPsec VPN with customers in those markets and check latency over that connection
  C. Use the Internet Intelligence tool. Run tests using the web server's public IP address and review traceroute details from different vantage points
  D. Setup a FastConnect with customers in those markets and check latency over that connection
  C. Use the Internet Intelligence tool. Run tests using the web server's public IP address and review traceroute details from different vantage points
