Q14. 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.)

Change the alarm’s metric interval to 1.

Change the alarm condition to be grater than 3%.

Change the notificationtopic that you previously associated with the alarm.

Change the alarm’s trigger delay minutes value to 1.

Q15. 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.)

‘touch’ command is not available in Oracle Linux by default.

Service limits or quota for file system writes have been breached.

Useris not part of any OCI Identity and Access Management group with write permissions to File Storage service.

User is connecting as the default Oracle Linux user ‘opc’ instead of ‘root’ user.

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 orCentOS 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.

Q16. Which statement about Oracle Cloud Infrastructure paravirtualized block volume attachments is TRUE?
(Choose the best answer.)

Paravirtualized volumes may reduce the maximum IOPS performance for larger block volumes.

Paravirtualized is required to manage iSCSI configuration for virtual machine instances.

Paravirtualized volumes become immediately available on bare metal compute instances.

Paravirtualization utilizes the internal storage stack of compute instance OS and network hardware virtualization to access block volumes.

Explanation
https://docs.oracle.com/en-us/iaas/Content/Block/Concepts/overview.htm#Paravirtualized

Q17. You have created an Autonomous Data Warehouse (ADW) service in your company’s Oracle Cloud Infrastructure (OCI) tenancy and you now have to load historical data into it. You have already extracted this historical data from multiple data marts and data warehouses. This data is stored in multiple CSV text files and these files are ranging in size from 25 MB to 20 GB.
Which is the most efficient and error tolerant method for loading data into ADW? (Choose the best answer.)

CreateAuth token, use it to create an object storage credential by executing DBMS_CLOUD.CREATE_CREDENTIAL, using the web console upload the CSV files to an OCI object storage bucket, create the tables in the ADW database and then execute DBMS_CLOUD.COPY_DATA foreach CSV file to copy the contents into the corresponding ADW database table.

Create the tables in the ADW database and then execute SQL*Loader for each CSV file to load the contents into the corresponding ADW database table.

Create Auth token, useit to create an object storage credential by executing DBMS_CLOUD.CREATE_CREDENTIAL, using OCI CLI upload the CSV files to an OCI object storage bucket, create the tables in the ADW database and then execute Data Pump Import for each CSV file to copy the contents into the corresponding ADW database table.

Create Auth token, use it to create an object storage credential by executing DBMS_CLOUD.CREATE_CREDENTIAL, using OCI CLI upload the CSV files to an OCI object storage bucket, create the tables in the ADW database and then execute DBMS_CLOUD.COPY_DATA for each CSV file to copy the contents into the corresponding ADW database table.

Explanation
Using Object Storage and COPY_DATA is the standard recommended method for fetching data into ADW.
Furthermore using CLI over web has the benefit of multipart upload, that is chunk upload of large files, thus reducing the chance of a transfer failure

Q18. One of the compute instances that you have deployed on Oracle Cloud Infrastructure (OCI) is malfunctioning.
You have created a console connection to remotely troubleshoot it.
Which two statements about console connections are TRUE? (Choose two.)

It is not possible to use VNC console connections to connect to Bare Metal Instances.

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.

It is not possible to connect to the serial console to an instance running Microsoft Windows, however VNC console connection can beused.

For security purpose, the console connection will not let you edit system configuration files.

If you do not disconnect from the session, your serial console connection will automatically be terminated after 24 hours.

Explanation
https://docs.oracle.com/en-us/iaas/Content/Compute/References/serialconsole.htm

Q19. A subscriber of an Oracle Cloud Infrastructure (OCI) Notifications service topic complained about not receiving messages from the service.
Which optioncan help you debug this issue? (Choose the best answer.)

If OCI Notifications service does not receive an acknowledgement from a subscription endpoint, the service drops the message. Confirm that the subscriber is always online to receive messages to help debug the issue.

If OCI Notifications service does not receive an acknowledgement from a subscription endpoint, check the NumberOfNotificationFailed metric through the OCI Monitoring service for failed messages. Copy these messages to an OCI ObjectStorage bucket. Make sure the subscriber has the required credentials to access this bucket to help debug the issue.

If OCI Notifications service does not receive an acknowledgement from a subscription endpoint, the service tries to redeliver messages for up to one day. Make sure that the subscriber is online at least once a day to help debug the issue.

If OCI Notifications service does not receive an acknowledgement from a subscription endpoint, the service tries to redeliver messages for up to two hours. Configure an alarm on the NumberOfNotificationFailed metric through the OCI Monitoring service to help debug the issue.

Explanation
https://www.oracle.com/devops/notifications/faq/
When a subscriber’s endpoint doesn’t acknowledge receipt of a message, the service retries delivery and currently retains the message up to two hours from the time the message is published to a topic. The service tries to deliver messages within the retentionwindow.

Q20. You have been contracted by a local e-commerce company to assistwith enhancing their online shopping application. The application is currently deployed in a single Oracle Cloud Infrastructure (OCI) region. The application utilizes a public load balancer, application servers in a private subnet, and a database in a separate, private subnet.
The company would like to deploy another set of similar infrastructure in a different OCI region that will act as standby site. In the event of a failure at the primary site, all customers should be routed to the failover site automatically.
After deploying the additional infrastructure within the second region, how should you configure automated failover requirements? (Choose the best answer.)

Create a load balancer policy in the Traffic Management service. Configure one answerfor each site. Set the answer for the primary site with a weight of 10 and the answer for the secondary site with a weight of 100.

Create a new A record in DNS that points to the public load balancer at the secondary site. Create a CNAME for the sub-domain failover that will resolve to the new A record. Inform customers to prepend the website URL with failover if the primary site is unavailable.

Create a failover policy in the Traffic Management service. Set the IP address of the public load balancerfor the primary site in answer pool 1. Set the IP address of the public load balancer for the secondary site in answer pool 2. Define a health check to monitor both sites.

Deploy a new load balancer in the primary region. Create one backend set for theprimary application servers and a second backend set for the standby application servers. Create a listener for the primary backend set with a timeout of 3 minutes. Create a listener for the secondary backend set with a timeout of 10 minutes.

Q21. You created an Oracle Linux compute instance through the Oracle Cloud Infrastructure (OCI) management console then immediately realize you forgot toadd 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.)

You need to configure the boot loader to use ttyS0 as a console terminal on the VM.

You need to terminate the running instance and recreate it by providing the SSH key file.

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.

You need to modify the serial console connection string to include the identity file flag, -i to specify the SSH key to use.

Explanation
If you created an instance without an SSH key, you can use the serial console toboot 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.

Q22. You run a large global application with 90% of customers based in the US and Canada. You want to be able to test a new feature and allow a small percentage of users to access the new version of your application.
What Oracle Cloud Infrastructure Traffic Management steering policy should you utilize? (Choose the best answer.)

Load Balancer

IP Prefix steering

ASN steering

Geolocation steering

Explanation
https://docs.oracle.com/en-us/iaas/Content/TrafficManagement/Tasks/trafficmanagement.htm

Q23. 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 ofthe boot volume.
Which step should NOT be included in the process used to solve the issue? (Choose the best answer.)

Reattach the boot volume and restart the instance.

Attach the resized boot volume to a second instance as a data volume; extend the partition and grow the file system in the resized boot volume.

Stop the instance and detach the boot volume.

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

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

Q24. Which technique does NOT help you get the optimal performance out of the Oracle Cloud Infrastructure (OCI) File Storage service? (Choose the best answer.)

Limit access to the same Availability Domain (AD) as the File Storageservice where possible.

Serialize operations to the file system to access consecutive blocks as much as possible.

Right size compute instances from where file system is accessed based on their network capacity.

Increase concurrency by using multiple threads, multiple clients, and multiple mount targets.

Explanation
“File Storage performance increases with parallelism. Increase concurrency by using multiple threads, multiple clients, and multiple mount targets.”

Q25. You are using Oracle Cloud Infrastructure (OCI) services across several regions: us-phoenix-1, us-ashburn-1, uk-london-1 and ap-tokyo-1. You have creates a separateadministrator group for each region: PHX-Admins, ASH-Admins, LHR-Admins and NRT-Admins, respectively.
You want to restrict admin access to a specific region. E.g., PHX-Admins should be able to manage all resources in the us-phoenix-1 region only and not any other OCI regions.
What IAM policy syntax is required to restrict PHX-Admins to manage OCI resources in the us-phoenix-1 region only? (Choose the best answer.)

Allow group PHX-Admins to manage all-resources in tenancy where request.region= ‘phx’

Allow group PHX-Admins to manage all-resources in tenancy where request.permission= ‘phx’

Allow group PHX-Admins to manage all-resources in tenancy where request.target= ‘phx’

Allow group PHX-Admins to manage all-resources in tenancy where request.location= ‘phx’

Explanation
Use conditions to limit access depending on region:
request.regionhttps://docs.oracle.com/en-us/iaas/Content/Identity/Reference/policyreference.htm#General

Q26. You are asked to implement the disaster recovery (DR) and business continuity requirements for Oracle Cloud Infrastructure (OCI) Block Volumes. Two OCI regions being used: a primary/source region and a DR/destination region. The requirements are:
* There should be a copy of data in the destination region to use if a region-wide disaster occurs in the source region
* Minimize costs
Which design will help you meet these requirements? (Choose the best answer.)

Clone block volumes. Use Object Storage lifecycle management to automatically move clone objects to Archive Storage. Copy Archive Storage buckets from source region to destination at regular intervals.

Clone block volumes. Copy block volume clonesfrom source region to destination region at regular intervals.

Back up block volumes. Copy block volume backups from source region to destination region at regular intervals.

Back up block volumes. Use Object Storage lifecycle management to automatically move backup objects to Archive Storage. Copy Archive Storage buckets from source region to destination at regular intervals.

Explanation
https://docs.oracle.com/en-us/iaas/Content/Block/Tasks/copyingvolumebackupcrossregion.htm

Q27. 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 newinstances.
What can you check to determine why the application is NOT functioning properly? (Choose the best answer.)

Verify that the new offer feature code did not introduce any performance bugs.

Verify that the database is accessible.

Verifythat the compute resource quota has not been exceeded.

Verify that the Quality Assurance team is not currently performing load-testing against production.

Q28. Multiple teams are sharing a tenancy in OracleCloud Infrastructure (OCI). You are asked to figure out an appropriate method to manage OCI costs.
Which is NOT a valid technique to accurately attribute costs to resources used by each team? (Choose the best answer.)

Create a Cost-Tracking tag. Apply this tag to all resources with team information. Use the OCI cost analysis tools to filter costs by tags.

Create separate compartment for each team. Use the OCI cost analysis tools to filter costs by compartment.

Create an Identity and Access Management (IAM) group for each team. Create an OCI budget for each group to track spending.

Define and use tags for resources used by each team. Analyze usage data from the OCI Usage Report which has detailed information about resources and tags.

Explanation
Budgets are set on cost-tracking tags or on compartments not by user groups

Q29. Which two statements are TRUE about Object Storage data security and encryption in Oracle Cloud Infrastructure (OCI)? (Choose two.)

Client-side encryption is managed by the customer.

Data needs to be decrypted on the client side before retrieving it.

OCI Vault Management is used by default to provide data security.

All traffic to and from Object Storage service is encrypted using TLS.

A VPN connection to OCI is required to ensure secure data transfer to an object storage bucket.

Q30. You have been asked to ensure that in-transit communication between an OracleCloud Infrastructure (OCI) compute instance and an on-premises server (192.168.10.10/32) is encrypted. The instances communicate using HTTP. The OCI Virtual Cloud Network (VCN) is connected to the on-premises network by two separate connections: a DynamicIPsec VPN tunnel and a FastConnect virtual circuit. No static configuration has been added.
What solution should you recommend? (Choose the best answer.)

The instances will communicate by default over IPsec VPN, which ensures data is encrypted in-transit.

Advertise a 192.168.10.10/32 route over the VPN.

Advertise a 192.168.10.10/32 router over the FastConnect.

The instances will communicate by default over the FastConnect private virtual circuit, which ensures data is encrypted in-transit.

Q31. You are launching a Windows server in your Oracle Cloud Infrastructure (OCI) tenancy.You provided a startup script during instance initialization, but it was not executed successfully.
What is a possible reason for this error? (Choose the best answer.)

Didn’t include anything in user_data.

Wrote a custom script which tried to install GPU drivers.

Ran a cloudbase-init script instead of cloud-init.

Specified a #directive on the first line of your script.

Q32. You havecreated a geolocation steering policy in the Oracle Cloud Infrastructure (OCI) Traffic Management service, with this configuration:

What happens to requests that originate in Africa? (Choose the best answer.)

The traffic will be forwarded at the same time to both Pool 1 and Pool 2.

The traffic will be dropped.

The traffic will be forwarded randomly to any of the pools mentioned in the rules.

The traffic will be forwarded to Pool 1. If Pool 1 is not available, then it will be forwarded toPool 2.

Explanation
This policy currently has no global catch-all. No global catch-all means that queries not matching any of the above rules will receive a random answer. Global Catche-all need to set up if the traffic does not meet any condition in the pool and you still want to serve the request. Default is serve randomly.
