NEW QUESTION 18
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-phoenix-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? (Choose the best answer.)
- A. 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.
- B. Create an instance with 1 OCPU shape. Use the Resize Instance action to scale up to a larger shape when more resources are needed.
- 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.Standard2.1 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.

NEW QUESTION 20
You created an Oracle Linux compute instance through the Oracle Cloud Infrastructure (OCI) management console then immediately realize you forgot to add an SSH key file. You notice that OCI compute service provides instance console connections that supports adding SSH keys for a running instance. Hence, you created the console connection for your Linux server and activated it using the connection string provided. However, now you get prompted for a username and password to login.
What option should you recommend to add the SSH key to your running instance, while minimizing the administrative overhead? (Choose the best answer.)
- A. You need to reboot the instance from the console, boot into the bash shell in maintenance mode, and add SSH keys for the opc user.
- B. You need to terminate the running instance and recreate it by providing the SSH key file.
- C. You need to configure the boot loader to use ttyS0 as a console terminal on the VM.
- D. You need to modify the serial console connection string to include the identity file flag, -i to specify the SSH key to use.
Answer: A
Explanation:
If you created an instance without an SSH key, you can use the serial console to boot into maintenance mode and add or reset the SSH key for the opc user or reset the password for the opc user. Alternately, you can stop the instance, attach the boot volume to a new instance, and configure SSH on the new instance.

NEW QUESTION 21
Recently, your e-commerce web application has been receiving significantly more traffic than usual. Users are reporting they often encounter a 503 Service Error when trying to access your site. Sometimes the site is very slow.
You check your instance pool configuration to confirm that the maximum number of instances is configured to allow 20 compute instances. Currently, 14 compute instances have been provisioned by the instance pool.
You also confirm that current CPU utilization across all hosts exceeds the scale-out threshold you set in your auto-scaling policy. However, the instance pool is not provisioning any new instances.
What can you check to determine why the application is NOT functioning properly? (Choose the best answer.)
- A. Verify that the database is accessible.
- B. Verify that the new offer feature code did not introduce any performance bugs.
- C. Verify that the Quality Assurance team is not currently performing load-testing against production.
- D. Verify that the compute resource quota has not been exceeded.
Answer: D
NEW QUESTION 22
You launched a Linux compute instance to host the new version of your company website via Apache Httpd server on HTTPS (port 443). The instance is created in a public subnet along with other instances. The default security list associated to the subnet is:
You want to allow access to the company website from public internet without exposing websites eventually hosted on the other instances in the public subnet.
Which action would you take to accomplish the task? (Choose the best answer.)
- A. Create a new security list with a stateful rule to allow ingress access on port 443 and associate it to the public subnet.
- B. Create a network security group, add a stateful rule to allow ingress access on port 443 and associate it to the public subnet that hosts the company website.
- C. Create a network security group, add a stateful rule to allow ingress access on port 443 and associate it to the instance that hosts the company website.
- D. In default security list, add a stateful rule to allow ingress access on port 443.
Answer: C
NEW QUESTION 23
A developer has created a file system in Oracle Cloud Infrastructure (OCI) File Storage service. She launches an Oracle Linux compute instance and successfully mounts the file system from the instance.
She then tries writing to the file system from the compute instance using the following command:
touch /mnt/yourmountpoint/helloworld
But gets an error message:
touch: cannot touch '/mnt/yourmountpoint/helloworrld': Permission denied Which is a reason for this error? (Choose the best answer.)
- A. Service limits or quota for file system writes have been breached.
- B. User is not part of any OCI Identity and Access Management group with write permissions to File Storage service.
- C. User is connecting as the default Oracle Linux user 'opc' instead of 'root' user.
- D. 'touch' command is not available in Oracle Linux by default.
Answer: C
Explanation:
https://docs.oracle.com/en-us/iaas/Content/File/Troubleshooting/cannotwrite.htm When a file system is created, the root user owns the root directory. If you're connecting from an instance that uses a Linux or CentOS platform image, the default user is opc. The default user is ubuntu when you connect from an instance that uses an Ubuntu platform image. These default users are not root users, so you can't initially write a file or directory to a new file system with these users.
NEW QUESTION 24

- B. It is not possible to use VNC console connections to connect to Bare Metal Instances.
- C. VNC console connection uses SSH port forwarding to create a secure connection from your local system to the VNC server attached to your instance's console.
- D. If you do not disconnect from the session, your serial console connection will automatically be terminated after 24 hours.
- E. For security purpose, the console connection will not let you edit system configuration files.
