You are using the Oracle Cloud Infrastructure Command Line Interface to launch a Linux virtual machine. You enter the following command (with correct values for all parameters):
The command fails.
Which is NOT a valid parameter in this command? (Choose the best answer.)
In the command line for launching a Linux virtual machine using the Oracle Cloud Infrastructure Command Line Interface, the parameter --t <tenancy_id> is not valid. The tenancy is specified during the OCI CLI configuration setup and is not required in the launch instance command. Parameters required for launching an instance include --availability-domain, --compartment-id, --shape, --display-name, --image-id, --ssh-authorized-keys-file, and --subnet-id.
You have received an email from your manager to provision new resources on Oracle Cloud Infrastructure (OCI). When researching OCI, you determined that you should use OCI Resource Manager. Since this is a task that will be done multiple times for development, test, and production. You will need to create a command that can be re-used.
Which CLI command can be used in this situation? (Choose the best answer.)
The correct CLI command to provision new resources on Oracle Cloud Infrastructure (OCI) using OCI Resource Manager for a task that will be done multiple times, such as creating new Production environments, is 'oci resource-manager stack create'. This command is specifically used to create a new stack. The command includes the compartment-id, configuration source (prod.zip), variable file (variables.json), display name, and description, making it reusable for different environments such as development, test, and production.
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.)
The most cost-effective approach is to use a VM.Standard2.1 shape instance with 1 OCPU each and set up autoscaling with a minimum of 2 instances and a maximum of 8 instances. This setup ensures that the application can handle the normal load (2 OCPUs), spike to handle weekly increases (up to 4 OCPUs), and scale up significantly for the end-of-month major usage uptick (up to 8 OCPUs), all while utilizing the smallest instance size to minimize costs during periods of lower demand.
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.)
To meet the requirements of low latency, consistency, performance of 1.25 Gbps, and encrypted data in transit, provisioning FastConnect with a single private virtual circuit and running an IPsec VPN tunnel over this circuit is the best solution. FastConnect provides low-latency, high-performance connectivity without performance variation. The IPsec VPN tunnel over the private virtual circuit ensures that the data in transit is encrypted, meeting the security requirements. This approach also balances cost-effectiveness while fulfilling all specified requirements.
Which two statements about the Oracle Cloud Infrastructure (OCI) Command Line Interface (CLI) are TRUE? (Choose two.)
The CLI for Oracle Cloud Infrastructure allows users to filter output using the JMESPath query option for JSON, which provides powerful capabilities for processing JSON data. Additionally, the CLI offers the same core functionality as the Console and includes additional commands, making it a versatile tool for managing and automating cloud resources.
