1z0-997-22 Exam Question 11

You are working with a social media company as a solution architect. The media company wants to collect and analyze large amounts of data being generated from their websites and social media feeds to gain insights and continuously improve the user experience. In order to meet this requirement, you have developed a microservices application hosted on Oracle Container Engine for Kubernetes. The application will process the data and store the result to an Autonomous Data Warehouse (ADW) instance.
Which Oracle Cloud Infrastructure (OCI) service can you use to collect and process a large volume of unstructured data in real time?

A.OCI Notifications

B.OCI Streaming

C.OCI Resource Manager

D.OCI Events

1z0-997-22 Exam Question 12

An OCI Architect is working on a solution consisting of analysis of data from clinical trials of a pharmaceutical company. The data is being stored in OCI Autonomous Data Warehouse (ADW) having 8 CPU Cores and 70 TB of storage. The architect is planning to setup autoscaling to respond to dynamic changes in the workload.
Which of the following needs to be considered while configuring auto scaling? Choose two

A.Enabling auto scaling does not change the concurrency and parallelism settings

B.Auto scaling also scales IO throughput linearly along with CPU

C.The database memory SGA and PGA will not get affected by the changes in the number of CPUs during auto scaling

D.The maximum CPU cores that will be automatically allocated for this database is 16 CPUs

You are developing a Serverless function for your company's IoT project. This function should access Oracle Cloud Infrastructure (OCI) Object Storage to store some files. You choose Oracle Functions to deploy this function on OCI. However, your security team doesn't allow you to carry any API Token or RSA Key to authenticate the function against the OCI API to access the Object Storage.
What should you do to get this function to access OCI Object Storage without carrying any static authentication files? (Choose the best answer.)

A.Option A

B.Option B

C.Option C

D.Option D

1z0-997-22 Exam Question 14

You developed a microservices based application that runs on Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). Your security team wants to use SSL termination for this application. What should you do to create a secure SSL termination for this application using fewest steps?

A.Create a self-signed certificate and it's corresponding key. Create a Kubernetes secret using then add these annotationsto the Kubernetes service.
Service.beta.kubernete.io/oci-load-balancer-ssl-ports: "443"
Service.beta.kubernete.io/oci-load-balancer-tls-secret:SSL-CERTIFICATE-SECRET

B.Generate a self-signed certificate using Let's Encrypt. Use that certificate on OCI Load Balancer. Create the Kubernetes service usingthis load balancer.

C.Add these annotationsto the Kubernetes service:
annotations:
service.beta.kubernetes.io/oci-load-balancer-ssl-ports: "443"
service.beta.kubernetes.io/oci-load-balancer-ssl-secret-key: ssl-secret-key

D.Create a self-signed certificate and it's corresponding key. Create a Kubernetes secret using the certificate and the key. Then add these an notations to the Kubernetes service:
annotations:
service.beta.kubernetes.io/oci-load-balancer-ssl-ports: "443"
service.beta.kubernetes.io/oci-load-balancer-security-list-management-mode:"Frontend"

1z0-997-22 Exam Question 15

After performing maintenance on an Oracle Linux compute instance the system is returned to a running state You attempt to connect using SSH t to do so. You decide to create an instance console connection to troubleshoot the issue.
Which three tasks would enable you to connect to the console connection and begin troubleshooting?

A.Use SSH to connect to the public: IP address of the compute Instance and provide the console connection OCID as the username.

B.edit the Linux boot menu to enable access to console.

C.Use SSH to connect to the service endpoint of the console connection service

D.Reboot the compute instance using the Oracle Cloud Infrastructure (OCI) Management Console

E.Upload an API signing key for console connection authentication.

F.Stop the compute Instance using the Oracle cloud Infrastructure (OCI) Command Line interface (CLI).

Correct Answer: B,C,D

The Oracle Cloud Infrastructure Compute service provides console connections that enable you to remotely troubleshoot malfunctioning instances, such as:
An imported or customized image that does not complete a successful boot.
A previously working instance that stops responding.
the steps to connect to console and troubleshoot the OS Issue
1- Before you can connect to the serial console you need to create the instance console connection.
Open the navigation menu. Under Core Infrastructure, go to Compute and click Instances.
Click the instance that you're interested in.
Under Resources, click Console Connections.
Click Create Console Connection.
Upload the public key (.pub) portion for the SSH key. You can browse to a public key file on your computer or paste your public key into the text box.
Click Create Console Connection.
When the console connection has been created and is available, the status changes to ACTIVE.
2- Connecting to the Serial Console
you can connect to the serial console by using a Secure Shell (SSH) connection to the service endpoint of the console connection service Open the navigation menu. Under Core Infrastructure, go to Compute and click Instances.
Click the instance that you're interested in.
Under Resources, click Console Connections.
Click the Actions icon (three dots), and then click Copy Serial Console Connection for Linux/Mac.
Paste the connection string copied from the previous step to a terminal window on a Mac OS X or Linux system, and then press Enter to connect to the console.
If you are not using the default SSH key or ssh-agent, you can modify the serial console connection string to include the identity file flag, -i , to specify the SSH key to use. You must specify this for both the SSH connection and the SSH ProxyCommand, as shown in the following line:
ssh -i /<path>/<ssh_key> -o ProxyCommand='ssh -i /<path>/<ssh_key> -W %h:%p -p 443...
Press Enter again to activate the console.
3- Troubleshooting Instances from Instance Console Connections
To boot into maintenance mode
Reboot the instance from the Console.
When the reboot process starts, switch back to the terminal window, and you see Console messages start to appear in the window. As soon as you see the GRUB boot menu appear, use the up/down arrow key to stop the automatic boot process, enabling you to use the boot menu.
In the boot menu, highlight the top item in the menu, and type e to edit the boot entry.
In edit mode, use the down arrow key to scroll down through the entries until you reach the line that starts with either linuxefi for instances running Oracle Autonomous Linux 7.x or Oracle Linux 7.x, or kernel for instances running Oracle Linux 6.x.
At the end of that line, add the following:
init=/bin/bash
Reboot the instance from the terminal window by entering the keyboard shortcut CTRL+X.
