Oracle 1Z0-1072-20 Online Questions & Answers

• Question 191:

  You are running an online gaming application hosted on a VM.Standard2.1 instance shape in Oracle Cloud Infrastructure. As the game becomes popular, you identify network throughput as a bottleneck on your instance when uploading user data.

  Though you want to resolve the issue, you want to observe the demand for a week before adding new application instances. Which action is the most efficient way to resolve this issue?

  A. Add a secondary virtual network interface card (VNIC).
  B. Change shape of the instance to a higher network bandwidth instance.
  C. Delete the instance while preserving boot volume and spin up a new higher network bandwidth instance with this boot volume.
  D. Change the performance tier of attached block volume to High Performance.
  B. Change shape of the instance to a higher network bandwidth instance.

• Question 192:

  You have multiple applications installed on a compute instance and these applications generate a large amount of log files. These log files must reside on the boot volume for a minimum of 15 days and must be retained for at least 60 days.

  The 60-day retention requirement is causing an issue with available disk space.

  What are the two recommended methods to provide additional boot volume space for this compute instance? (Choose two.)

  A. Terminate the instance while preserving the boot volume. Create a new instance from the boot volume and select a DenseIO shape to take advantage of local NVMe storage.
  B. Create an object storage bucket and use a script that runs daily to move log files older than 15 days to the bucket.
  C. Create and attach a block volume to the compute instance and copy the log files.
  D. Create a custom image and launch a new compute instance with a larger boot volume size.
  E. Write a custom script to remove the log files on a daily basis and free up the space on the boot volume.
  B. Create an object storage bucket and use a script that runs daily to move log files older than 15 days to the bucket.
  D. Create a custom image and launch a new compute instance with a larger boot volume size.

  These log files must reside on the boot volume for a minimum of 15 days so you have to increase the boot Volume

• Question 193:

  Which statement is true about cloning a volume?

  A. You need to detach a volume before cloning from it.
  B. A cloned volume is the same as a snapshot that has a dependency on the source volume.
  C. You can change the block volume size when cloning a volume.
  D. You can create a clone for a volume across regions.
  C. You can change the block volume size when cloning a volume.

• Question 194:

  Which two statements are true about Oracle Cloud Infrastructure (OCI) DB Systems?

  A. Customers have no control over database patching.
  B. The database and backups are encrypted by default.
  C. Customers can consolidate multiple database homes on a single virtual machine database host.
  D. Customers can manage the TDE Wallet after DB Systems is provisioned.
  B. The database and backups are encrypted by default.
  D. Customers can manage the TDE Wallet after DB Systems is provisioned.

  ---

  All databases created in Oracle Cloud Infrastructure are encrypted using transparent data encryption (TDE).

  Oracle Cloud Infrastructure encrypts all managed backups in the object store. Oracle uses the Database Transparent Encryption feature by default for encrypting the backups. and the customers can manage the TDE Wallet after DB Systems

  are provisioned.

• Question 195:

  You have an application running on Oracle Cloud Infrastructure. You identified that the read and write operations are slowing your application down enough to impair user access. The application is currently using a VM.Standard 1.2 compute without any block storage attached to it. Which two options allow you to increase disk performance? (Choose two.)

  A. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Dense IO shape using the boot volume preserved.
  B. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Standard shape and attach a new block volume to host your application.
  C. Create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.
  D. Terminate the compute instance and create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.
  A. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Dense IO shape using the boot volume preserved.
  B. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Standard shape and attach a new block volume to host your application.

  ---

  You can permanently terminate (delete) instances that you no longer need.By default, the instance's boot volume is deleted when you terminate the instance, however you can preserve the boot volume associated with the instance, so that

  you can attach it to a different instance as a data volume, or use it to launch a new instance.

  You can use a boot volume backup to create an instance or you can attach it to another instance as a data volume. However before you can use a boot volume backup, you need to restore it to a boot volume.

• Question 196:

  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

  The second tool, OCI IP Troubleshooting, helps troubleshoot issues with public facing IP addresses. This feature is also part of our Internet Intelligence toolset, providing analytical insight to help network operations teams reduce the time it takes to troubleshoot an issue by providing awareness of availability and latency across the Internet.

• Question 197:

  You are planning to deploy a multi-region web application in Oracle Cloud Infrastructure (OCI). You have customers in North America, Asia and Europe who will access the application. What service is available in OCI to help you choose the regions the lowest latency to these markets?

  A. Internet Intelligence
  B. FastConnect
  C. IPsec VPN
  D. DNS Zone Management
  A. Internet Intelligence

• Question 198:

  You have been asked to create an Identity and Access Management (IAM) user that will authenticate to Oracle Cloud Infrastructure (OCI) API endpoints. This user must not be given credentials that would allow them to log into the OCI

  console.

  Which two authentication options can you use? (Choose two.)

  A. SSL certificate
  B. API signing key
  C. SSH key pair
  D. PEM Certificate file
  E. Auth token
  B. API signing key
  E. Auth token
