Oracle 1Z0-1072-20 Online Questions & Answers

• Question 101:

  You are working for a financial institution that is currently running two web applications in Oracle Cloud

  Infrastructure (OCI). All resources were created in the root compartment. Your manager asked you to deploy new resources to support a proof-of-concept (PoC) for Oracle FlexCube.

  You must ensure that the FlexCube resources are secured and cannot be affected by the team that manages the two web applications.

  Which two tasks should you complete to ensure the required security of your resources? (Choose two.)

  A. Create a new compartment for the two web applications and move the existing resources into the compartment. Deploy the FlexCube application into the root compartment. Create a new policy in the root compartment that gives the FlexCube project team the ability to manage all resources in the tenancy.
  B. Create a new policy in the root compartment for the FlexCube project team. Assign a policy statement that grants the FlexCube project team the ability to manage all resources in the tenancy, where a specific tag key and tag value are present.
  C. Create a Tag Default within the root compartment with a default value of ${iam.principle.name} so that each new resource created is tagged with the name of the person who created it. Create a new IAM policy that allows users to only modify resources they created.
  D. Create a new compartment for the two web applications and move the existing resources into this compartment. Modify the existing policy for the team that manages these applications so that the scope of access is defined as this new compartment.
  E. Create a new compartment for the FlexCube application deployment. Create a policy in this compartment for the project team that gives them the ability to manage all resources within the scope of this compartment.
  C. Create a Tag Default within the root compartment with a default value of ${iam.principle.name} so that each new resource created is tagged with the name of the person who created it. Create a new IAM policy that allows users to only modify resources they created.
  D. Create a new compartment for the two web applications and move the existing resources into this compartment. Modify the existing policy for the team that manages these applications so that the scope of access is defined as this new compartment.

• Question 102:

  You want an Oracle Cloud Infrastructure (OCI) compute instance in your compartment to make API calls to other services within OCI without storing credentials in a configuration file. What do you need to do?

  A. Create a dynamic group with appropriate matching rules to include the instance, and reference this group in your IAM policy statement
  B. Instances cannot access services outside their compartment
  C. VM instances are treated as users. Create a user, assign the user to that VM instance, and reference the instance in your Identity and Access Management (IAM) policy statement
  D. By default, all VM instances are created with an instance principal. Reference this instance principal in your IAM policy statement
  A. Create a dynamic group with appropriate matching rules to include the instance, and reference this group in your IAM policy statement

• Question 103:

  Which two configuration formats does Terraform support? (Choose two.)

  A. YAML
  B. JSON
  C. HCL
  D. XML
  B. JSON
  C. HCL

  ---

  References:

  Terraform configuration files can use either of two formats: Terraform domain-specific language (HashiCorp Configuration Language format [HCL]), which is the recommended approach, or JSON format if the files need to be machine

  readable.

• Question 104:

  Which three are valid Terraform configuration components? (Choose three.)

  A. variable
  B. region
  C. metadata
  D. instance
  E. resource
  F. data source
  A. variable
  E. resource
  F. data source

• Question 105:

  What is the maximum IP address size range that you can have in a Virtual Cloud Network?

  A. /16
  B. /26
  C. /24
  D. /8
  A. /16

  ---

  When you create your VCN, you assign a contiguous IPv4 CIDR block of your choice. VCN sizes ranging from /16 (65,533 IP addresses) to /30 (1 IP address) are allowed. Example: 10.0.0.0/16, 192.168.0.0/24.

• Question 106:

  

  

  Which of the following two tasks can be performed in the Oracle Cloud Infrastructure Console for Autonomous Data Warehouse?

  A. Adjust Network Bandwidth
  B. Scale up/down Memory
  C. Increase Storage allocated for Database
  D. Scale up/down CPU
  C. Increase Storage allocated for Database
  D. Scale up/down CPU

  ---

  You can scale up/down your Autonomous Database to scale both in terms of compute (CPU) and storage only when needed, allows people to pay per use. Oracle allows you to scale compute and storage independently, no need to do it

  together. these scaling activities fully online (no downtime required) in Details page Autonomous Database in OCI console, click Scale Up/Down. Click on arrow to select a value for CPU Core Count or Storage (TB).

  Or Select auto scaling to allow the system to automatically use up to three times more CPU and IO resources to meet workload demand, compared to the database operating with auto scaling disabled.

• Question 107:

  An Oracle Cloud Infrastructure tenancy administrator is not able to delete a user in the tenancy. What can cause this issue?

  A. User has multi-factor authentication (MFA) enabled.
  B. User is member of an Identity and Access Management (IAM) group.
  C. Users can be blocked but not deleted.
  D. User needs to be deleted from federation Identity Provider (IdP) before deleting from IAM.
  A. User has multi-factor authentication (MFA) enabled.

• Question 108:

  Which scaling option does Database Cloud Service (DBCS) on Bare Metal Shape offer?

  A. network bandwidth
  B. CPU
  C. storage
  D. memory
  B. CPU

• Question 109:

  You must implement a backup solution for your Autonomous Data Warehouse (ADW) that will enable you to restore data as old as one year with a recovery point objective (RPO) of 10 days. Which database backup strategy would you select?

  A. Take weekly manual backups to supplement the automated backups and preserve them for 12 months.
  B. Use the automated backups.
  C. Take monthly manual backups to supplement the automated backups and preserve them for 12 months.
  D. Take quarterly manual backups to supplement the automated backups and preserve them for 12 months.
  B. Use the automated backups.

  ---

  Oracle Cloud Infrastructure automatically backs up your Autonomous Databases and retains these backups for 60 days. Automatic backups are weekly full backups and daily incremental backups. You can also create manual backups to supplement your automatic backups. Manual backups are stored in an Object Storage bucket that you create, and are retained for 60 days The retention period for manual backups is the same as automatic backups which is 60 days. So we cannot preserve the backup for 12 months https://docs.oracle.com/en/cloud/paas/autonomous-data-warehouse-cloud/user/backup- manual.html#GUID-D95E5D6A-C470-4A68-9545-CC99D937E7D1

• Question 110:

  Your application consists of three Oracle Cloud Infrastructure compute instances running behind a public load balancer. You have configured the load balancer to perform health checks on these instances, but one of the three instances fails to pass the configured health check. Which of the following action will the load balancer perform?

  A. Stop sending traffic to the instance that failed health check
  B. Terminate the instance that failed health check
  C. Stop the instances that failed health check
  D. Remove the instance that failed the health check from the backend set
  A. Stop sending traffic to the instance that failed health check

  ---

  health check A test to confirm the availability of backend servers. A health check can be a request or a connection attempt. Based on a time interval you specify, the load balancer applies the health check policy to continuously monitor

  backend servers. If a server fails the health check, the load balancer takes the server temporarily out of rotation. If the server subsequently passes the health check, the load balancer returns it to the rotation.

  You configure your health check policy when you create a backend set. You can configure TCP-level or HTTP-level health checks for your backend servers.

  -

  TCP-level health checks attempt to make a TCP connection with the backend servers and validate the response based on the connection status.

  -

  HTTP-level health checks send requests to the backend servers at a specific URI and validate the response based on the status code or entity data (body) returned. The service provides application-specific health check capabilities to help you increase availability and reduce your application maintenance window.
