1Z1-1072 by Oracle Valid Free Exam Practice Test

Question 1

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.Standard2.1 compute without any block storage attached to it. Which two options allow you to increase disk IOPS performance?

A. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.Standard2.2 shape using the boot volume preserved and attach a new block volume to host your application. B. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.DenseI02.8 shape using the boot volume preserved and use the NVMe devices to host your application. C. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.Standard2.2 shape using the boot volume preserved, but no block volume attached. D. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved, but no block volume attached.

Correct Answer: B,D

Question 2

Which two statements are true about restoring a volume from a block volume backup in Oracle Cloud Infrastructure Block Volume service?

A. You can only restore a volume to the same availability domain in which the original block volume resides. B. You can restore a block volume backup to a larger volume size. C. You can restore a volume to any availability domain within the same region where the backup is stored. D. You can restore a volume from any full volume backup but not from an Incremental backup. E. You can restore only one volume from a manual block volume backup.

Correct Answer: B,C

Question 3

You must implement a backup solution for your Autonomous Data Warehouse (ADW) that will enable you to restore data as old as one year with a recovery point objective (RPO) of 10 days.
Which database backup strategy would you select?

A. Take monthly manual backups to supplement the automated backups and preserve them for 12 months. B. Take weekly manual backups to supplement the automated backups and preserve them for 12 months. C. Take quarterly manual backups to supplement the automated backups and preserve them for 12 months. D. Use the automated backups.

Billing stops for both CPU and storage usage when autonomous database is stopped. D. Billing for storage usage continues when autonomous database is stopped. E. Billing does not stop when autonomous database is terminated.

Question 6

You have deployed a compute instance (VM.Standard2.24) to run an Oracle database. With this set up, you run into some performance issues and want to leverage an OCI Dense IO shape (VM.DenseIO2.24), with which you get 25.6 TB local NVMe SSD. You do not want to lose the configuration changes you made to the instance. Which of the following TWO steps ARE NOT required to make this transition?

A. Create a new instance using a VM.DenseIO2.24 shape using the preserved boot volume and move the Oracle Database data to block volumes B. Terminate the VM.Standard2.24 instance and do not preserve the boot volume C. Terminate the VM.Standard2.24 instance and preserve the boot volume D. Create a new instance using the VM.Dense102.24 shape using the preserved boot volume and move the Oracle Database data to NVMe disks

Question 8

You are about to upload log file (5 TiB size) to Oracle Cloud Infrastructure object storage and have decided to use multipart upload capability for a more efficient and resilient upload. Which two statements are true about multipart upload? (Choose two.)

A. You do not have to commit the upload after you have uploaded all the object parts B. While a multipart upload is still active, you cannot add parts even if the total number of parts is less than 10,000 C. Individual object parts can be as small as 10 MiB or as large as 50 GiB D. The maximum size for an uploaded object is 10 TiB

A VCN resolver allows instances to use host names to communicate with instances on other VCNs in your tenancy. C. A VCN resolver allows instances to use the host names of the hosts in your on-prem network that are connected to your VCN by an IPSec VPN connection. D. An Internet resolver allows instances to use the host names that are published on the Internet.
