Question 1

Single choice

You have been asked to ensure that in-transit communication between an Oracle Cloud 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 Dynamic IPsec 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.

Question 2

Single choice

You have created a group for several auditors. You assign the following policies to the group:

What actions are the auditors allowed to perform within your tenancy? (Choose the best answer.)

The Auditors can view resources in the tenancy.

Auditors are able to create new instances in the tenancy.

The Auditors are able to delete resource in the tenancy.

Auditors are able to view all resources in the compartment.

Question 3

Single choice

You have a web application running on Oracle Cloud Infrastructure (OCI) that lets users log in with a username and password. You notice that an attacker has tried to use SQL comment "--" to alter the database query, remove the password check and log in as a user. You decide to prevent any future attacks.

Which of the following OCI services or features would you choose to safeguard your application? (Choose the best answer.)

Network Security Group

Data Safe

Web Application Framework (WAF)

Vault

Question 4

Multiple choice

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 be used.

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.

Question 5

Single choice

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.)

Create Auth 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 for each 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, 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 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.

Question 6

Single choice

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.)

-t <tenancy_id>

- -image-id <image_id>

- -shape "<shape_name>"

-c <compartment_id>

- -subnet-id <subnet_id>

Question 7

Single choice

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.)

oci resource-manager stack create --tenancy-id <tenancy_OCID> \
--config-source prod.zip --variables file://variables.json \
--display-name Production stack build \
--description Creating new Production environment

oci resource-manager stack update --compartment-id <compartment_OCID> \
--config-source prod.zip --variables file://variables.json \
--display-name "Production stack build" \
--description Creating new Production environment

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

oci resource-manager stack update --tenancy-id <tenancy_OCID> \
--config-source prod.zip --variables file://variables.json \
--display-name "Production stack build" \
--description Creating new Production environment

Question 8

Single choice

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.)

Create an instance pool with a VM.Standard2.2 shape instance configuration. Setup the autoscaling configuration to use 2 availability domains and have a minimum of 2 instances, to handle the weekly spikes, and a maximum of 4 instances.

Create an instance with 1 OCPU shape. Use the Resize Instance action to scale up to a larger shape when more resources are needed.

Create an instance with 1 OCPU shape. Use a CLI script to clone it when more resources are needed.

Create an instance pool with a VM.Standard2.1 shape instance configuration. Setup the autoscaling configuration to use 2 availability domains and have a minimum of 2 instances and a maximum of 8 instances.

Question 9

Single choice

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.)

Provision FastConnect with a single private virtual circuit, and run an IPsec VPN tunnel over the top of this virtual circuit.

Provision FastConnect with a single public virtual circuit.

Provision a site-to-site IPsec VPN between your on-premises network and your virtual cloud network
(VCN) using VPN Connect.

You can run CLI commands from inside OCI Regions only.

You can filter CLI output using the JMESPath query option for JSON.

The CLI provides an automatic way to connect with instances provisioned on OCI.

The CLI allows you to use the Python language to interact with OCI APIs.
