Question 1

The boot volume on your Oracle Linux instance has run out of space. Your application has crashed due to a lack of swap space, forcing you to Increase the size of the boot volume.
Which step should NOT be Included In the process used to solve the Issue?

A. Reattach the boot volume and restart the instance.

B. Create a RAID 0 configuration to extend the boot volume file system onto another block volume.

C. Resize the boot volume by specifying a larger value than the boot volume's current size.

D. Attach the resized boot volume to a second instance as a data volume; Extend the partition and grow the file system on the resized boot volume.

Question 2

You are asked to deploy a new application that has been designed to scale horizontally. The business stakeholders have asked that the application be deployed In us-phoenlx-1.
Normal usage requires 2 OCPUs. You expect to have few spikes during the week, that will require up to 4 OCPUs, and a major usage uptick at the end of each month that will require 8 OCPUs.
What is the most cost-effective approach to implement a highly available and scalable solution?

A. Create an instance with 1 OCPU shape. Use the Resize Instance action to scale up to a larger shape when more resources are needed.

B. Create an instance pool with a VM.Standard2.1 shape instance configuration. Setup the autoscaling configuration to use 2 availability domains and have a minimum of 2 instances and a maximum of 8 instances.

C. Create an instance with 1 OCPU shape. Use a CLI script to clone It when more resources are needed.

D. Create an instance pool with a VM.Standard2.2 shape instance configuration. Setup the autoscaling configuration to use 2 availability domains and have a minimum of 2 instances, to handle the weekly spikes, and a maximum of 4 Instances.

Question 3

Your company recently adopted a hybrid cloud architecture which requires them to migrate some of their on-premises web applications to Oracle Cloud Infrastructure OCI). You created a Terraform template which automatically provisions OCI resources such as compute instances, load balancer, and a database instance. After running the stack using the terraform apply command, it successfully launched the compute Instances and the load balancer, but it failed to create a new database Instance with the following error:
Service error:NotAuthorizedOrNotFound. shape VM.Standard2.4 not found, http status code: 404 You discovered that the resource quotas assigned to your compartment prevent you from using VM.Standard2.4 instance shapes available in your tenancy. You edit the Terraform script and replace the shape with VM.Standard2.2.
Which option would you recommend to re-run the terraform command to have required OCI resources provisioned with the least effort?

A. terraform refresh -target=oci_database_db_system.db_system

B. terraform plan -target=oci_database_db_system.db_system

C. terraform apply -auto-approve

D. terraform apply -target=ocl_database_db_system.db_system

Question 5

You set up a bastion host in your VCN to only allow your IP address (140.19.2.140) to establish SSH connections to your Compute instances that are deployed private subnet. The Compute instances have an attached Network Security Group with a Source Type: Network security Group (NSG) , Source NSG: -050504. To secure the bastion host, you added the following ingress rules to its Network Security Group:

However, after checking the bastion host logs, you discovered that there are IP addresses other than your own that can access your bastion host.
What is the root cause of this issue?

A. The port 22 provides unrestricted access to 140.19.2.140 and to other IP address

B. A netmask of /32 allows all IP address in the 140.19.2.0 network, other than your IP 110.19.2.140

C. The Security List allows access to all IP address which overrides the Network Security Group ingress rules.

D. All compute instances associated with NSG-050504 are also able to connect to the bastion host.

Question 6

You have deployed a three-tier web application inside an Oracle Cloud Infrastructure (OCI) VCN with a CIDR block of 10.0.0.0/28. You Initially deploy three web servers (VM.Standard2.2), two application servers (VM.Standard2.4), and two servers (VM.Standard2.8) running Oracle database.
The web, application and database servers are deployed across two availability domains in the us-ashburn-1 region.
You also deployed a Public Load Balancer In front of the two web servers. The web traffic gradually Increases In the first few days following the deployment, so you attempt to double the number of instances in each tier of the application to handle the new load. Unfortunately, some of these new Instances fail to launch.
Your tenancy comes with the following set of predefined services limits for the availability domain and compartment where the application is deployed.

What is a possible reason for this deployment to fail?

A. You do not have enough private IP addresses left to launch all of the new compute instances.

B. You do not have sufficient public IP addresses required by the web, application and database servers.

C. You do not have sufficient quotas for number of VM.Standard2.2, VM.Standard2.4 and VM.Standard2.8 shapes in the Production compartment in the us-ashburn-1 region.

D. You do not have sufficient quotas for number of VM.Standard2.2, VM.Standard2.4 and VM.Standard2.8 shapes in each availability domain in the us-ashburn-1 region.
