Oracle Oracle Cloud Solutions Infrastructure 1Z0-1072-22 Questions & Answers

• Question 31:

  You have an application running on Oracle Cloud Infrastructure. You Identified that the read and write operations are slowing your application down enough to impair user access. The application is currently using a VM.Standard2.1 compute without any block storage attached to it. Which two options allow you to increase disk IOPS performance?

  A. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.DenseI02.8 shape using the boot volume preserved and use the NVMe devices to host your application.

  B. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.Standard2.2 shape using the boot volume preserved and attach a new block volume to host your application.

  C. Terminate the compute instance preserving the boot volume. Create a new compute instance using the VM.Standard2.2 shape using the boot volume preserved, but no block volume attached.

  D. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved, but no block volume attached.

  Correct Answer: AD

• Question 32:

  You are an administrator with an application running in Oracle Cloud Infrastructure (OCI). The company has a fleet of OCI compute virtual instances behind an load balancer. The load balancer backend set health check API is providing a 'Critical' level warning. You have confirmed that your application Is running healthy on the backend servers. What Is the possible reason for this 'Critical' warning?

  A. The load balancer listener is not configured correctly.

  B. The security list associated with the subnet In which the backend server is provisioned does not include the IP range for the source of the health check requests.

  C. A user does not have correct Identity and Access Management (IAM) credentials on the backend servers.

  D. The route table associated with the subnet in which the backend server is provisioned does not include the route for the OCI load balancer.

  Correct Answer: B

• Question 33:

  A company currently uses Microsoft Active Directory as its identity provider. The company recently subscribed to Oracle Cloud Infrastructure (OCI) to leverage the cloud platform for test and development. As the administrator, you configured the OCI tenancy to be federated with Microsoft Active Directory. Now you need to give access to developers so that they can start creating resources in their OCI accounts. Which step will you perform to make sure you are not duplicating user creation inside of OCI tenancy?

  A. Create a group for developers on OCI and map the group to a similar group in Microsoft Active Directory during the federation process.

  B. Create a new user account in OCI for each user, and then create policies to provide access to developers.

  C. Create a group for developers on OCI, export all the developers from Microsoft Active Directory, and then import them into the Identity and Access Management (IAM) group.

  D. Create a single user account in OCI, and then create policies to provide access to developers to this single account.

  Correct Answer: A

  When working with your IdP, your administrator defines groups and assigns each user to one or more groups according to the type of access the user needs. Oracle Cloud Infrastructure also uses the concept of groups (in conjunction with IAM policies) to define the type of access a user has. As part of setting up the relationship with the IdP, your administrator can map each IdP group to a similarly defined IAM group, so that your company can re-use the IdP group definitions when authorizing user access to Oracle Cloud Infrastructure resources.

• Question 34:

  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

  Correct Answer: A

  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 35:

  Which two statements are true about Oracle Cloud Infrastructure (OCI) DB Systems?

  A. Customers have no control over database patching.

  B. The database and backups are encrypted by default.

  C. Customers can consolidate multiple database homes on a single virtual machine database host.

  D. Customers can manage the TDE Wallet after DB Systems is provisioned.

  Correct Answer: BD

  All databases created in Oracle Cloud Infrastructure are encrypted using transparent data encryption (TDE). Oracle Cloud Infrastructure encrypts all managed backups in the object store. Oracle uses the Database Transparent Encryption feature by default for encrypting the backups. and the customers can manage the TDE Wallet after DB Systems are provisioned.

• Question 36:

  You are running your warehouse using Autonomous Data Warehouse (ADW) service and you noticed that a newly configured batch job is always running in serial even through nothing else is running in the database. All your jobs are configured to run with parallelism enabled. What could be the reason for this batch job to run in serial?

  A. The batch job depends on only one table and parallelism cannot be enabled on single-table queries.

  B. The parallelism of batch job depends on the number of ADW databases involved in the query.

  C. The new batch job is connected to LOW consumer group.

  D. The new batch job runs on database tables that are not enable for parallel execution.

  E. Parallelism on the database is controlled by the application, not the database.

  Correct Answer: C

• Question 37:

  Which statement is true about DB Systems?

  A. Data Guard as a Service is offered between regions.

  B. You cannot manage the database as sys/sysdba.

  C. You have full control over the automatic backup schedule and retention periods.

  D. You can manage Oracle database initialization parameters at a global level.

  Correct Answer: BC

• Question 38:

  Which two options are available when configuring DNS resolution for your virtual cloud network? (Choose two.)

  A. Internet and custom resolver

  B. Google DNS servers

  C. custom resolver

  D. Internet and virtual cloud network (VCN) resolver

  Correct Answer: CD

• Question 39:

  Which two statements are true about data guard service on DB Systems in Oracle Cloud Infrastructure (OCI)?

  A. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal.

  B. Data guard implementation requires two DB Systems, one containing the primary database and one containing the standby database.

  C. Data guard configuration on the OCI is limited to a virtual machine only.

  D. Both DB Systems must use the same VCN, and port 1521 must be open.

  Correct Answer: BD

• Question 40:

  You are tasked with creating a highly available clustered application on Oracle Cloud Infrastructure

  consisting of three nodes. The round-trip latency between nodes must be less than 500 祍 (microseconds) and your cluster should be resilient to hardware failure.

  What is the recommended deployment strategy?

  A. Deploy the cluster nodes in a single region and deploy each node into a different AD. Select the same fault domain in each AD to ensure consistency.

  B. Deploy the cluster nodes in two separate regions and take advantage of multiple availability domains (ADs) in each region.

  C. Deploy the cluster nodes in a single region and deploy each node into a different AD.

  D. Deploy the cluster nodes in a single region and deploy each node in different fault domains within a single AD.

  Correct Answer: D
