- 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 NumberofNotificationFaiied metric through the OCI Monitoring service to help debug the issue
- Resource manager stacks are free. There are no fees for installing and managing Resource Manager, you only pay for the infrastructure you deploy and use for your applications.
- If you do not disconnect from the session, your serial console connection will automatically be terminated after 24 hours.
- 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
- OCI Ansible Modules represent discrete provisioning tasks or operations that you can invoke individually from the command line, or else run Individually or in sequence from a playbook.
- OCI Ansible Modules enable orchestrating, provisioning, and configuration management tasks on Oracle Cloud Infrastructure
-
Automate the provisioning of this new environment: OCI Resource Manager
-
Add the SSH key to your running Instance: modify the serial console connection string to include the identity file flag, -I to specify the SSH key to use
-
key benefit of using Resource Manager for your Terraform provisioning and management activities: Resource Manager manages the Terraform state file for your infrastructure and locks the file so that only one Job at a time can run on a given stack
-
Does NOT help you get the optimal performance out of the OCI File Storage service: Serialize operations to the file system to access consecutive blocks as much as possible
-
Encryption of data in-transit: Native Oracle Net Services encryption and integrity capabilities
-
Ensure that data being accessed by the application is encrypted: Native Oracle Net Services encryption and integrity capabilities
-
Essential components of the Oracle Cloud Infrastructure Notifications service: A topic with a name unique across the tenancy, a subscription, and a message where content is published
-
Application is NOT functioning properly: Verify that the compute resource quota has not been exceeded
-
Make IPSec VPN connection highly available (HA): Add another Customer-Premises Equipment (CPE) and create second IPSec VPN connection with the same Dynamic Routing Gateway (DRG)
-
Unable to access an internal application running behind Public Load Balancer using a compute instance pool with auto scaling enabled. Some deleted items In the Audit Log while troubleshooting. The route table rules associated with the subnet within the VCN
-
Include a quota to allow for use of only 20 VM.Standard shapes per Availability Domain: set compute quota vm-standard2-2-count to 20 in compartment dev
-
Control the costs and avoid any overspending: Associate a Budget Tag to each compartment with the monthly budget amount and set an alert rule to notify the developers' teams when they reached a specific percentage of the budget
-
NOT a valid technique to accurately attribute costs to resources used by each team: Create an Identity and Access Management (IAM) group for each team. Create an OCI budget for each group to track spending
-
Make API calls to other services without storing credentials in a configuration file: Create appropriate matching rules in the Dynamic Group to create an Instance Principal
-
Daily Incremental backups need to be retained for at least 50 days: Enable automatic backups and choose the preset retention period of 60 days
-
Oracle allow as part of vulnerability and penetration tests testing: Customers are allowed to use their own testing and monitoring tools
-
Develop an Ansible playbook to centralize configuration file management and deployment: Download the dynamic inventory script provided by Oracle Cloud Infrastructure and include It in the playbook Invocation command
-
Delete all the temporary data with /temp prefix: oci os object bulk-delete -ns vision -bn app-data --prefix /temp --force
-
Download the archive file as quickly as possible:(get , 128) oci os object get -ns my-namespace -bn my-bucket --name my-large-object --multipart-download-threshold 2000 --part-size 128
-
You want to restrict admin access to a specific region. E.g., PHX-Admlns: Allow group PHX-Admins to manage all-resources in tenancy where request.region = 'phx'
-
Service error:NotAuthorizedOrNotFound. shape VM.Standard2.4 not found, http status code: 404: terraform apply -auto-approve
-
metric query showing all read IOPS at a one-minute interval, filtered to this compartment and aggregated for the maximum: IopsRead[lm]{compartmentId="ocidl.compartment.ocl.phx..exampleuniquelD"}.grouplng().max()
Required parameters to launch an instance in Oracle Cloud:
- Virtual Cloud Network
- subnet
- Availability Domain
- instance shape
- image operating system
TRUE for OCI Compute Service:
- You can launch a virtual or bare metal instance by using the same LaunchInstance API
- You can share custom images across tenancies and regions
Configured for a load balancer to accept incoming traffic:
- a listener
- a back-end server
- a back end set
Two parameters are required in a back end set’s HTTP health check:
- Port
- URL Path
High Availability on Oracle Cloud Infrastructure:
- Configure your database to have Data Guard in another Availability Domain in Sync mode within a region.
- Distribute your application servers across all Availability Domains within a region.
Valid targets for creating a budget In OCI:
- Select Cost-Tracking Tags as the type of target for your budget.
- Select Compartment as the type of target for your budget
Copy of data in the destination region to use If a region-wide disaster occurs in the source region + Minimize costs:
- Backup block volumes.
- Copy block volume backups from source region to destination region at regular intervals
Load historical data(25 MB -20 GB) stored in CSV text files to ADW:
- Create Auth token
- Create an object storage credential by executing DBMS_CI OUD.CREATE _CREDENTIAL
- Using OCI CLI upload the CSV files to an OCI object storage bucket.
- Create the tables in the ADW database
- Execute DBMS_CLOUD.COPY_DATA for each CSV file to copy the contents into the corresponding ADW database table
True about the Bulk Export of OCI Audit Log Events:
- Exported logs are available in the object storage buckets in your tenancy.
- Exported logs remain available indefinitely
Identify excessive spend across all resources in your tenancy:
- Create a tag namespace named BILLING with a Tag Key named CostCenter.
- Tag each of your resources with this Tag Key and the correct value
To manage alarms In OCI, which three actions can be performed through the OCI Console:
- View alarm history for last 3 months.
- View all the firing alarms.
- Move an alarm to a different compartment
Manage multiple environments using OCI CLI: Use OCI CLI profiles to create multiple set of credentials in your config file, and reference the appropriate profile at runtime
Lifecycle policy for object storage: oci os object-lifecycle-pollcy put -ns <object_storage_namespace> -bn <bucket_name> -Items<json_formatted_llfecycle_policy>
Copy an object from Object Storage: oci os object copy --namespace-name <object_storage_namespace> --bucket-name <source_bucket_name> --source-object-name <source_object> --destination-namespace <destination_namespace_string> --destination-region <destination_region> --destination-bucket <destination_bucket_name> --destination-object-name <destination_object_name>
Provision new resources on OCI multiple times through CLI: oci resource-manager stack create --compartment-id <compartment_OCID> --config-source prod.zip --variables file://variables.json --display-name "Production Stack build" --description "Creating new Production environment"
Command Line Interface to launch a Linux virtual machine fails. Which is invalid parameter: -t <tenancy_id>
