Oracle Cloud Infrastructure 2021 Cloud Operations Associate - 1Z0-1067-21 Exam Practice Test

Your customer is running a set of compute instances inside a private subnet to manage their workloads on Oracle Cloud Infrastructure (OCI) tenancy. You have set up auto scaling feature to provide consistent performance to their end users during period of high demand.
Which step should be met for auto scaling to work? (Choose the best answer.)

You have been asked to set up connectivity between a client's on-premises network and Oracle Cloud Infrastructure (OCI). The requirements are:
Low latency: The applications are financial and require low latency connectivity into OCI. Consistency: The application isn't tolerant of performance variation.
Performance: The communications link needs to support up to 1.25 Gbps.
Encryption: The communications link needs to encrypt any data in transit between the on-premises network and OCI Virtual Cloud Network (VCN).
The client wants to implement the above with as low a cost as possible, while meeting all of the requirements. What should you suggest? (Choose the best answer.)

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 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.)

You have set an alarm to be generated when the CPU usage of a specified instance is greater than 10%. In the alarm behavior view below you notice that the critical condition happened around 23:30. You were expecting a notification after 1 minute, however, the alarm firing state did not begin until 23:33.

What should you change to fix it? (Choose the best answer.)

Which option contains the essential components of the Oracle Cloud Infrastructure Notifications service? (Choose the best answer.)
