Question 11

A global retailer has decided to re-design its e-commerce platform to have a micro-services architecture. They would like to decouple application architecture into smaller, independent services using Oracle Cloud Infrastructure (OCI). They have decided to use both containers and servers technologies to run these application instances.
Which option should you recommend to build this new platform?

A.Install a kubernetes cluster on OCI and use OCI event service.
B.Use Oracle Container Engine for kubernetes, OCI Registry and OCI Functions.
C.Use OCI Resource Manager to automate compute Instances provisioning and use OCI Streaming service.
D.Use OCI functions, OCI object storage and OCI event service.

Question 12

After performing maintenance on an Oracle Linux compute instance the system is returned to a running state You attempt to connect using SSH but are unable 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.

Question 13

You have been asked to implement a bespoke financial application in Oracle Cloud Infrastructure using virtual machine instances controlled by Autoscaling across multiple Availability Domains. The application stores transaction logs, intermediate transaction data, and audit data and needs to store this on a persistent, durable data store accessible from all of the application servers. The application requires the file system to be mounted in the /audit folder on the Linux file system. The system needs to tolerate the failure of two or more Fault Domains and still maintain data integrity. The solution should be as low maintenance as possible.
What storage architecture should you suggest?

A.Implement a single instance and install an NFS server, configure and create an NFS share, and mount this as /audit on the application instances.
B.Use File Storage Service(FSS). Configure FSS to operate from all Availability Domains the application servers operate in and mount the file system in the /audit folder.
C.Use locally attached NVMe instances and configure RAID 0 replication between servers.
D.Store the data on Oracle Object Storage mounted at the /audit mount point on all the Linux instances using the default mount options.

Question 14

You are working as a cloud consultant for a major media company. In the US and your client requested to consolidate all of their log streams, access logs, application logs, and security logs into a single system.
The client wants to analyze all of their logs In real-time based on heuristics and the result should be validated as well. This validation process requires going back to data samples extracted from the last 8 hours.
What approach should you take for this scenario?

A.Create an auto scaling pool of syslog-enabled servers using compute instances which will store the logs In Object storage, then use map reduce jobs to extract logs from Object storage, and apply heuristics on the logs.
B.Create a bare-metal instance big enough to host a syslog enabled server to process the logs and store logs on the locally attached NVMe SSDs for rapid retrieval of logs when needed.
C.Set up an OCI Audit service and ingest all the API arils from Audit service pragmatically to a client side application to apply heuristics and save the result in an OCI Object storage.
D.Stream all the logs and cloud events of Events service to Oracle Streaming Service. Build a client process that will apply heuristics on the logs and store them in an Object Storage.

Question 15

An insurance company is storing critical financial data in the OCI block volume. This volume is currently encrypted using oracle managed keys. Due to regulatory compliance, the customer wants to encrypt the data using the keys that they can control and not the keys which are controlled by Oracle.
What of the following series of tasks are required to encrypt the block volume using customer managed keys?

A.Create a vault, import your master encryption key into the vault, generate data encryption key, assign data encryption key to the block volume
B.Create a master encryption key, create a data encryption key, decrypt the block volume using existing oracle managed keys, encrypt the block volume using the data encryption key
C.Create a vault, create a master encryption key in the vault, assign this master encryption key to the block volume
D.Create a master encryption key, create a new version of the encryption key, decrypt the block volume using existing oracle managed keys and encrypt using new version of the encryption key
