Question 66

An eCommerce company is running on Oracle Cloud Infrastructure (OCI) and many compute instances remain unused for the most part of the year except during Black Friday and Christmas. You suggest them to use OCI's Autoscaling feature and present them a slide to showcase the features of Autoscaling.
Which option below is inaccurate in your presentation to the customer?

A.Autoscaling relies on performance metrics such as CPU utilization that are collected by OCI Monitoring service to trigger an Autoscaling event.
B.When an instance pool scales in, instances are terminated in this order: the number of instances is balanced across Availability Domains, and then balanced across Fault Domains. Finally, within a Fault Domain, the newest instance is terminated first.
C.A cooldown period between Autoscaling events lets the system stabilize at the updated level.
D.Autoscaling requires an instance pool as a pre-requisite so that it can automatically adjust the number of compute instances in an instance pool.

Question 67

A large London based eCommerce company is running Oracle DB System Virtual RAC database on Oracle Cloud Infrastructure (OCI) for their eCommerce application activity. They are launching a new product soon, which is expected to sell in large quantities all over the world.
The application architecture should have minimal cost, no data loss, no performance impacts during the database backup windows and should have minimal downtime.

A.Launch a new VM RAC database in another availability domain, launch a compute instance, deploy Oracle GoldenGate on it and then configure it to replicate the data from the eCommerce Database over to the new RAC database using GoldenGate. Take backups from the new VM RAC database.
B.Turn off automated backups from the eCommerce database, implement Oracle Data Guard with the Standby database deployed on another availability domain, take backups from the standby database.
C.Launch a new VM RAC database in another availability domain, launch a compute instance, deploy Oracle GoldenGate on it and then configure bi-directional replication from the eCommerce Database over to the new VM RAC database using GoldenGate. Take backups from the new VM RAC database.
D.Turn off automatic backups from the eCommerce database, implement Oracle Active Data Guard with the standby database deployed on another availability domain, and take backups from the standby database.

Question 68

Your company has recently deployed a new web application that uses Oracle functions Your manager Instructed you to Implement major manage your systems more effectively. You know that Oracle functions automatically monitors functions on your behalf reports metrics through Service Metrics.
Which two metrics are collected and made available by this feature?

A.length of time a function runs
B.number of times a function is removed
C.number of times a function is invoked
D.amount of CPU used by a function
E.number of concurrent connections

Question 69

A cloud consultant is working on implementation project on OCI. As part of the compliance requirements, the objects placed in object storage should be automatically archived first and then deleted. He is testing a Lifecycle Policy on Object Storage and created a policy as below:
[ { "name": "Archive_doc", "action": "ARCHIVE", "objectNameFilter": { "inclusionPrefixes": "doc"] },
"timeAmount": 5, "timeunit": "DAYS", "isEnabled": true },
{ "name": "Delete_doc", "action": "DELETE", "objectNameFilter": "inclusionPrefixes": [ "doc"]
1."timeAmount": 5, "timeunit": "DAYS", "isEnabled": true }
What will happen after this policy is applied?

A.All objects with names starting with "doc" will be deleted after 5 days of object creation
B.All the objects having file extension ".doc" will be archived for 5 days and will be deleted 10 days after object creation
C.All the objects having file extension ".doc" will be archived 5 days after object creation
D.All the objects with names starting with "doc" will be archived 5 days after object creation and will be deleted 5 days after archival

Question 70

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.
