1. Question 21 · 57 in bank

   You are responsible for deploying an application on Oracle Cloud Infrastructure (OCI). The application is memory intensive and performs poorly if enough memory is not available. You have created an instance pool of Linux compute instances in OCI to host the application and defined Autoscaling Configuration for the instance pool. What should you do to ensure that the instance pool autoscales to prevent poor application performance?

   • AInstall OCI SDK on all compute instances and create a script that triggers the autoscaling event if there is high memory usage.
   • BConfigure the autoscaling policy to monitor CPU usage and scale up the number of instances when it meets the threshold.
   • CInstall the monitoring agent on all compute instances, which triggers the autoscaling group.
   • DConfigure the autoscaling policy to monitor memory usage and scale up the number of instances when it meets the threshold.

   Answer: D

   Explanation

   D is correct. the question is about an application which is memory intensive. Auto scaling use CPU/Memory as performance metrics

2. Question 22 · 57 in bank

   You have a high-demand web application running on Oracle Cloud Infrastructure (OCI). Your tenancy administrator has set up a schedule-based autoscaling policy on instance pool with an initial size of 5 instances for the application. Policy 1: Target pool size: 10 instances - Execution time: 8:30 a.m. on every Monday through Friday, in every month, in every year Cron expression: 0 30 8 ? * MON-FRI * Which statement accurately explains the goal of this policy?

   • AGoal: A recurring weekly schedule. On all days of the week at 8.30 a.m., scale out the pool to 10 instances from the initial size of 5.
   • BGoal: A one-time schedule with only one scaling out event. At 8:30 a.m., on December 31, 2021, scale the instance pool to 10 instances from 5.
   • CGoal: A recurring daily schedule. On weekdays (Monday through Friday) at 8.30 a.m., scale out to 10 instances.
   • DGoal: A recurring monthly schedule. On all days of the month, set the initial pool size to 5 instances. At 8.30 a.m., on every day of the month, scale out to 10 instances.

   You just got a last minute request to create a set of instances in Oracle Cloud Infrastructure (OCI). The configuration and installed software are identical for every instance, and you already have a running instance in your OCI tenancy.

   • ABring your own image and use it as a template for the new instances.
   • BSelect an image from the OCI Marketplace.
   • CCreate a custom image and use it as a template for the new instances.
   • DUse Oracle-provided images and customize the installation using a third-party tool.

   You are backing up your on-premises data to the Oracle Cloud Infrastructure (OCI) Object Storage Service. Your requirements are: 1. Backups need to be retained for at least full 31 days. 2. Data should be accessible immediately if and when needed after the backup. Which OCI Object Storage tier is suitable for storing the backup to minimize cost?

   • AArchive tier
   • BInfrequent Access tier
   • CAuto-Tiering tier
   • DStandard tier

   Show answer

   Answer: B

   Explanation

   B. Infrequent Access tier: This tier is designed for data that is accessed less frequently but still requires quick access when needed. It offers a cost saving over the Standard tier while providing the ability to access data immediately. This would be a suitable option given your need for immediate access and a cost-effective solution.

   Select 2

   You plan to upload a large file (3 TiB) to Oracle Cloud Infrastructure (OCI) Object Storage. You would like to minimize the impact of network failures while uploading, and therefore you decide to use the multipart upload capability. Which TWO statements are true about performing a multipart upload using the Multipart Upload API? (Choose two.)

   • AYou do not have to commit the upload after you have uploaded all the object parts.
   • BYou do not need to split the object into parts. Object Storage splits the object into parts and uploads all of the parts automatically.
   • CWhile a multipart upload is still active, you can keep adding parts as long as the total number is less than 10,000.
   • DWhen you split the object into individual parts, each part can be as large as 50 GiB.

   Answer: CD

   Explanation

   When defining a query for metric data in Monitoring, which field provides the time window for aggregating metric data points plotted on the metric chart?

   • ANamespace
   • BInterval
   • CDimension
   • DStatistic

   Show answer

   Answer: B

   Explanation

   b Interval is the field that provides the time window for aggregating metric data points plotted on the metric chart. Interval is a parameter that specifies how often metric data points are collected and aggregated by the Monitoring service. For example, an interval of 5 minutes means that metric data points are aggregated every 5 minutes and displayed on the chart. The other options are not fields that provide the time window for aggregating metric data points, but rather other parameters that define the metric query. Reference: [Interval]

   You are using the Oracle Cloud Infrastructure (OCI) Vault service to create and manage Secrets. For your database password, you have created a secret and rotated the secret one time. The secret versions are as follows:

   

   You later realize that you have made a mistake in updating the secret content for version 2 and want to rollback to version 1. What should you do to rollback to version 1?

   • ADeprecate version 2 (latest). Create new Secret version 3. Create soft link from version 3 to version 1.
   • BFrom the version 1 menu on the OCI console, select "Promote to Current".
   • CFrom the version 2 (latest) menu, select "Rollback" and select version 1 when given the option.
   • DCreate a new secret version 3 and set to Pending. Copy the content of version 1 into version 3.

   Show answer

   Answer: B

   Explanation

   B when you've made a mistake in updating the secret contents or when you've restored a backup of an older resource and need to resume using older secret contents, secret versions can also be marked as 'previous.' A secret version marked as 'previous' was previously a secret version marked as 'current.' To roll back to a previous version, you update the secret to specify the secret version number you want. As long as a secret version hasn't been deleted, you can update the secret to use that past secret version. When you update the secret, the secret version number you choose gets marked as 'current.' This has the same effect as promoting a secret version to 'current.'

    You want to create a policy to allow the NetworkAdmins group to manage Virtual Cloud Network (VCN) in compartment C. You want to attach this policy to the tenancy. The compartment hierarchy is shown below.

    

    Which policy statement can be used to accomplish this task?

    • AAllow group NetworkAdmins to manage virtual-network-family in compartment C
    • BAllow group NetworkAdmins to manage virtual-network-family in compartment A:B:C
    • CAllow group NetworkAdmins to manage virtual-network-family in tenancy
    • DAllow group NetworkAdmins to manage virtual-network-family in compartment B:C

    Show answer

    Answer: B

    Explanation

    If you attach the policy further up the hierarchy, you must specify the path. The format of the path is each compartment name (or OCID) in the path, separated by a colon: : : . . . To attach this policy to the tenancy, write this policy statement that specifies the path from CompartmentA to CompartmentC: B Allow group NewtworkAdmins to manage virtual-network-family in compartment CompartmentA:CompartmentB:Compart
