B. Autonomous Data Warehouse (ADW) system as it provides auto fail over functionality
C. two node bare metal system with data guard enabled
D. single node bare metal system

Answer

A. two node real application cluster (RAC) system

Question 82

Question

You have been notified of an application failure indicating that one or more of the Oracle Cloud Infrastructure (OCI) resources have become unavailable. After scanning the Compute and Database consoles, you notice that one of the DB Systems is missing.
What would you do to identify the reason for this missing resource?

A. Navigate to the Audit console and search the previous 24 hours for all Delete actions to get a list of any resource that was deleted in the past 24 hours.
B. Create a serial console connection to the DB System that does not appear in the management console. Connect to the serial console connection, and then review the system logs under/var/log/messages.
C. View the service limits associated with your account to ensure that you have not exceeded the available number of DB system in your tenancy.
D. Navigate to the Audit console and search the previous 24 hours for all List actions to get a list of every event that occurred in the past 24 hours.

Answer

A. Navigate to the Audit console and search the previous 24 hours for all Delete actions to get a list of any resource that was deleted in the past 24 hours.

Explanation

You can filter results by request actions to zero in on only the events with operations that interest you. For example, say that you only want to know about instances that were deleted during a specific time frame. Select a delete request action filter to see only the events with delete operations

Question 83

Question

You create a public Load Balancer instance and configure a back end set “BES1” with one back end server running a service on port 80. You also create a listener on port 80 and configure that listener to use the back end set “BES1”. A client makes one HTTP request to the Load Balancer with the correct protocol and port.
How many connections does the Load Balancer maintain?

A. 1
B. 2
C. 4
D. 3

Answer

B. 2

Question 84

Question

Within your tenancy you have a compute instance with a boot volume and a block volume attached.
The boot volume contains the OS and the attached block volume contains the instance’s important data. Logs on the boot volume have filled the boot volume and are causing issues with the OS.
What should you do to resolve this situation?

A. Stop the instance that is full. Create a manual backup of the block storage before making changes. Detach the block volume, create a new instance of the same shape with a larger custom boot volume and attach the block volume to the new instance. Configure the OS and any related application(s) to access the block volume under the same mount point as before.
B. Create a new instance with a larger boot volume size as well a new block volume which is the same size or larger than the one attached to the full instance. rsync the state of the boot volume and the state of the block volume between the two instances.
C. Detach the block volume from the full instance. Create a new instance of the same shape with a larger boot volume and rsync the state of the boot volume between the instances. Attach the block volume to the new instance.
D. Create a manual backup of the block storage instance. Create a custom image of the full instance. Once that completes deploy the custom image to a new instance.

Question 85

Question

Your on-premises hosted application uses Oracle database server. Your database administrator must have access to the database server for managing the application. Your database server is sized for seasonal peak workloads, which results in high licensing costs. You want to move your application to Oracle Cloud Infrastructure (OCI) to take advantage of CPU scaling options.
Which database offering on OCI would you select?

A. bare metal DB systems
B. VM DB systems
C. Autonomous Transactions Processing (ATP)
D. Autonomous Data Warehouse (ADW)

Answer

A. bare metal DB systems

Explanation

In, Oracle Autonomous Database, Customers are not given OS logons or SYSDBA privileges to prevent phishing attacking.

If a bare metal DB system requires more compute node processing power, you can scale up (increase) the number of enabled CPU cores in the system without impacting the availability of that system.

You cannot change the number of CPU cores for a virtual machine DB system in the same way as metal DB system. Instead, you must change the shape to one with a different number of OCPUs

Changing the shape does not impact the amount of storage available to the DB system. However, the new shape can have different memory and network bandwidth characteristics, and you might need to reapply any customizations to these aspects after the change.

Question 86

Question

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.

Answer

B. Data guard implementation requires two DB Systems, one containing the primary database and one containing the standby database.
D. Both DB Systems must use the same VCN, and port 1521 must be open.

Explanation

When Autonomous Database instance is stopped, CPU billing is halted based on full-hour cycles of usage. Billing for storage continues as long as the service instance exists. When Autonomous Database instance is started, the CPU billing is initiated.

An Oracle Data Guard implementation requires two DB systems, one containing the primary database and one containing the standby database. When you enable Oracle Data Guard for a virtual machine DB system database, a new DB system with the standby database is created and associated with the primary database. For a bare metal DB system, the DB system with the database that you want to use as the standby must already exist before you enable Oracle Data Guard.

Requirement details are as follows:

Both DB systems must be in the same compartment.
The DB systems must be the same shape type (for example, if the shape of the primary database is a virtual machine, then the shape of the standby database can be any other virtual machine shape).
If your primary and standby databases are in different regions, then you must peer the virtual cloud networks (VCNs) for each database.
Configure the security list ingress and egress rules for the subnets of both DB systems in the Oracle Data Guard association to enable TCP traffic to move between the applicable ports. Ensure that the rules you create are stateful (the default).

Question 88

Question

Which two resources are available by default when your Oracle Cloud Infrastructure tenancy is provisioned?

A. an NVMe SSD boot disk for each instance, whose size is determined by the image and shape of the instance
B. a range of public IP addresses that are reserved for your tenancy
C. a set of images, where each image is a template of a virtual hard drive that consists of the OS and installed software and applications
D. a variety of shapes, where each shape determines the number of CPUs and memory allocated to an instance.

Answer

C. a set of images, where each image is a template of a virtual hard drive that consists of the OS and installed software and applications
D. a variety of shapes, where each shape determines the number of CPUs and memory allocated to an instance.

Question 89

Question

Your company has been running several small applications in Oracle Cloud Infrastructure and is planning a proof-of-concept (POC) to deploy PeopleSoft.
If your existing resources are being maintained in the root compartment, what is the recommended approach for defining security for the upcoming POC?

A. Create a new compartment for the POC and grant appropriate permissions to create and manage resources within the compartment.
B. Provision all new resources into the root compartment. Grant permissions that only allow for creation and management of resources specific to the POC.
C. Provision all new resources into the root compartment. Use defined tags to separate resources that belong to different applications.
D. Create a new tenancy for the POC. Provision all new resources into the root compartment. Grant appropriate permissions to create and manage resources within the root compartment.

Answer

A. Create a new compartment for the POC and grant appropriate permissions to create and manage resources within the compartment.

Explanation

If your organization is small, or if you are still in the proof-of-concept stage of evaluating OracleCloud Infrastructure, consider placing all of your resources in the root compartment (tenancy). This approach makes it easy for you to quickly view and manage all your resources. You can still write policies and create groups to restrict permissions on specific resources to only the users who need access. If you plan to maintain all your resources in the root compartment, we recommend setting up a separate sandbox compartment to give users a dedicated space to try out features. In the sandbox compartment, you can grant users permissions to create and manage resources, while maintaining stricter permissions on the resources in your tenancy (root) compartment.

Question 90

Question

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 though 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.

Answer

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