Question 7

- (Exam Topic 1)
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?

Configure ATP resource management rules to change CPU/IO shares for the consumer group of batch processes.

Copy OLTP data into new tables in a new table space and run batch processes against these new tables.

Disable automated backup during the batch process operations.

ATP is designed for OLTP workload only, you cannot run batch processes on ATP.

Question 8

- (Exam Topic 1)
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.)

Terminate the instance while preserving the boot volum

Create a new instance from the boot volume and select a DenseIO shape to take advantage of local NVMe storage.

Create an object storage bucket and use a script that runs daily to move log files older than 15 days to the bucket.

Create and attach a block volume to the compute instance and copy the log files.

Create a custom image and launch a new compute instance with a larger boot volume size.

Write a custom script to remove the log files on a daily basis and free up the space on the boot volume.

Question 12

- (Exam Topic 2)
You are in the process of setting up a highly available student registration website on Oracle Cloud Infrastructure (OCI). You use a load balancer and a database service on OCI. You launch two compute instances each in a different subnet and add them to the back end set of a public load balancer. The load balancer is configured correctly and working. You then deploy the student registration application on these two compute instances. The application can communicate with the database service. However, when you type the URL of this student registration application in your browser, no web page appears.
What could be the cause?

The security lists of the subnets on which the two instances are located do not have “allow” rules for port 80 and 443.

The load balancer performed a health check on the application and found that compute instances were not in a healthy state and terminated the instances.

The client requested https access to the application and the load balancer service does not support end-to-end SSL from the client to the listener to the back-end set.

The Dynamic Routing Gateway is preventing the client traffic from your data center network from reaching the public IP of the load balancer.

Question 13

- (Exam Topic 2)
Which three can you achieve by using Terraform? (Choose three.)

Create resources in the right order without regard to the order in the terraform plan file.

Automatically re-provision the resources that are tainted or whose configuration has changed.

Automatically translate a deployed infrastructure and create a plan.

Automatically destroy all the resources that are in tenancy.

Continuously maintain the configuration files in an instance.

Question 14

- (Exam Topic 2)
What is a “transfer package” when transferring data to OCI via the OCI Data Transfer Service?

A transfer package is the logical representation of the physical shipment containing the HDD transfer devices that you ship to Oracle to upload to OCI.

A transfer package is the software Oracle provides for you to prepare transfer devices for shipment to Oracle

A transfer package contains the physical devices.

A transfer package is the archive file that the Data Transfer Service Utility (dts) writes to the transfer device.

Question 21

- (Exam Topic 1)
Which two statements below are correct with respect to adding secondary Virtual Network Interface Cards (VNICs) to an existing compute instance in Oracle Cloud Infrastructure? (Choose two.)

The secondary VNIC is required to be in the same Virtual Cloud Network (VCN), but can be in different subnet, as the primary VNIC.

The primary and secondary VNIC association can be in different virtual cloud networks (VCNs).

You cannot assign an Ephemeral Public IP to a secondary VNIC.

The primary and secondary VNIC association must be in the same availability domain.

You can remove the primary VNIC after the secondary VNIC's attachment is complete.

Question 22

- (Exam Topic 1)
boot volume for a minimum of 15 days so you have to increase the boot
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?

Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.

Connect via SSH to one of the application servers where the file system has been mounte

Use the Unix command chmod to change permissions on the file system directory, allowing the database user read only access.

Modify the security list associated with the subnet where the mount target reside

Change the ingress rules corresponding to the DB System subnet to be stateless.

Create an instance principal for the DB Syste

Write an Identity and Access Management (IAM) policy that allows the instance principal read-only access to the file storage service.

Question 23

- (Exam Topic 1)
You have setup your environment as shown below with the Mount Target "MT" successfully mounted on both compute instances CLIENT-X and CLIENT-Y.
For security reasons you want to control the access to the File System A in such a way that CLIENT-X has READ/WRITE and CLIENT-Y has READ only permission.
1Z0-1072-20 dumps exhibit

What you should do?

Update the OS firewall in CLIENT-X to allow READ/WRITE access.

Update the security list TWO to restrict CLIENT-Y access to read-only.

Update the mount target export options to restrict CLIENT-Y access to read-only.

Update the security list ONE to restrict CLIENT-Y access to read only.
