An insurance company has contracted you to help automate their application business continuity plan. They have the application running in eu-frankfurt-1 as the primary site and uk-london-1 as a disaster recovery site. Normally they have a DNS A record associated with the IP address of the primary endpoint in eu-frankfurt-1. In the event of a disaster, they use OCI DNS Zone Management to update the A record and replace it with the IP address of the endpoint in uk-londond-1.
How can you automate the failover process? (Choose the best answer.)
A. Create a Health Check that evaluates both regional endpoints. Create a Traffic Management Steering policy with Failover type and associate it with the Health Check.
B. Create a Traffic Management Steering policy with Load Balancer type and add both eu-frankfurt-1 and uk-london-1 endpoints. Attach the Traffic Management Steering policy to the A record.
C. Provision a Load Balancer in Frankfurt and associate it with the A record in DNS. Create a backend set with backend servers from both eu-frankfurt-1 and uk-london-1 regions.
D. Create a Traffic Management Steering policy and attach it to a backend servers from both eu-frankfurt1 and uk-london-1 regions.
You are working as a Cloud Operations Administrator for your company. They have different Oracle Cloud Infrastructure (OCI) tenancies for development and production workloads. Each tenancy has resources in two regions – uk-london-1 and eu-frankfurt-1. You are asked to manage all resources and to automate all the tasks using OCI Command Line Interface (CLI).
Which is the most efficient method to manage multiple environments using OCI CLI? (Choose the best answer.)
A. Use OCI CLI profiles to create multiple sets of credentials in your config file, and reference the appropriate profile at runtime.
B. Create environment variables for the sets of credentials that align to each combination of tenancy, region, and environment.
C. Run oci setup config to create new credentials for each environment every time you want to access the environment.
D. Use different bash terminals for each environment.
Your team implemented a SaaS application that requires a whole system deployment for each new customer. The infrastructure provisioning is already automated via Terraform, and now you have been asked to develop an Ansible playbook to centralize configuration file management and deployment.
What is the most effective way to ensure your playbooks are utilizing up-to-date and accurate inventory? (Choose the best answer.)
A. Export an inventory list from the Oracle Cloud Infrastructure Web console.
B. Export an inventory list using Terraform apply command.
C. Implement a Command Line Interface script to list all the resources and run it within Ansible to generate a dynamic inventory list.
D. Download the dynamic inventory script provided by Oracle Cloud Infrastructure and include it in the playbook invocation command.
You have a 750 MIB file in an Oracle Cloud Infrastructure (OCI) Object Storage bucket. You want to download the file in multiple parts to speed up the download using the OCI CLI. You also want to configure each part size to be 128 MIB.
Which is the correct OCI CLI command for this operation? (Choose the best answer.)
A. oci os object get –ns my–namespace –bn my–bucket ––name my–large–object ––multipart–download– threshold 750 ––parallel–download–count 128
B. oci os object download –ns my–namespace –bn my–bucket ––name my–large–object ––multipart– download–threshold 750 ––parallel–download–count 128
C. oci os object download –ns my–namespace –bn my–bucket ––name my–large–object ––resume–put ––multipart–download–threshold 500 ––part–size 128
D. oci os object get –ns my–namespace –bn my–bucket ––name my–large–object ––multipart–download– threshold 500 ––part–size 128
Security Testing Policy describes when and how you may conduct certain types of security testing of Oracle Cloud Services, including vulnerability and penetration tests, as well as tests involving data scraping tools.
What does Oracle allow as part of this testing? (Choose the best answer.)
A. Customers are allowed to use their own testing and monitoring tools.
B. Customers can simulate DoS attack scenarios as long as it's restricted to the customer's own environment.
C. Customers can validate that their network resources are isolated from other customer resources.
D. Customers are allowed to test Oracle Cloud Infrastructure (OCI) hardware related to resources in their tenancy.
What is a key benefit of using Oracle Cloud Infrastructure's Resource Manager for your Terraform provisioning and management activities? (Choose the best answer.)
A. You can use Resource Manager to apply patches to all existing Oracle Linux interfaces in a specified compartment.
B. Resource Manager has administrative privileges by design. Even if your IAM user does not have access, you can leverage Resource Manager to provision new resources to any compartment in the Tenancy.
C. You can use Resource Manager to identify and maintain an inventory of all Compute and Database instances across your tenancy.
D. Resource Manager manages to Terraform state file for your infrastructure and locks the file so that only one job at a time can run on a given stack.
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 new offer feature code did not introduce any performance bugs.
B. Verify that the database is accessible.
C. Verify that the compute resource quota has not been exceeded.
D. Verify that the Quality Assurance team is not currently performing load-testing against production.
Which technique does NOT help you get the optimal performance out of the Oracle Cloud Infrastructure (OCI) File Storage service? (Choose the best answer.)
A. Limit access to the same Availability Domain (AD) as the File Storage service where possible.
B. Serialize operations to the file system to access consecutive blocks as much as possible.
C. Right size compute instances from where file system is accessed based on their network capacity.
D. Increase concurrency by using multiple threads, multiple clients, and multiple mount targets.
Your deployment platform within Oracle Cloud Infrastructure (OCI) leverages a compute instance with multiple block volumes attached. There are multiple teams that use the same compute instance and have access to these block volumes. You want to ensure that no one accidentally deletes any of these block volumes. You have started to construct the following IAM policy but need to determine which permissions should be used.
allow group DeploymentUsers to manage volume-family where ANY { request.permission != , request.permission != , request.permission != }
Which permissions can you use in place of in this policy? (Choose the best answer.)
A. VOLUME_DELETE, VOLUME_ATTACHMENT_DELETE, VOLUME_BACKUP_DELETE
B. VOLUME_ERASE, VOLUME_ATTACHMENT_ERASE, VOLUME_BACKUP_ERASE
C. ERASE_VOLUME, ERASE_VOLUME_ATTACHMENT, ERASE_VOLUME_BACKUP
D. DELETE_VOLUME, DELETE_VOLUME_ATTACHMENT, DELETE_VOLUME_BACKUP
You have a group pf developers who launch multiple VM.Standard2.2 compute instances every day into the compartment Dev. As a result, your OCI tenancy quickly hit the service limit for this shape. Other groups can no longer create new instances using VM.Standard2.2 shape.
Because of this, your company has issued a new mandate that the Dev compartment must include a quota to allow for use of only 20 VM.Standard2.2 shapes per Availability Domain. Your solution should not affect any other compartment in the tenancy.
Which quota statement should be used to implement this new requirement? (Choose the best answer.)
A. set compute quota vm-standard2–2count to 10 in compartment dev where request.region = usphoenix–1
B. set compute quota vm-standard2–2–count to 20 in compartment dev
C. zero compute quotas in tenancy set compute quota vm–standard2–2–count to 20 in compartment dev
D. zero compute quotas in tenancy set compute quota vm–standard2–2–count to 20 in tenancy dev
