NEW QUESTION 38
You are a network architect and have designed the network infrastructure of a three-tier application on Oracle Cloud Infrastructure (OCI). In the architecture, back-end DB servers are in a private subnet. One of your DB administrators requests to have access to OCI object storage service.
How can you meet this requirement?
- A. Create a service gateway, add a new route rule to the private subnet route table that uses object storage as target type.
- B. Attach a public IP address to the instances in the private subnet, and then add a new route rule to the private subnet route table to route default traffic to the internet gateway.
- C. Create a dynamic routing gateway (DRG) and attach it to your virtual cloud network (VCN). Add a default route rule to the private subnets route table and set the target as DRG.
- D. Add a new route rule to the private subnet route table to route default traffic to the internet gateway.
Answer: A
Explanation:
A service gateway lets resources in your VCN privately access specific Oracle services, without exposing the data to an internet gateway or NAT. The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the service of interest travels over the Oracle network fabric and never traverses the internet.
To give your VCN access to a given service CIDR label, you must enable that service CIDR label for the VCN's service gateway. You can do that when you create the service gateway, or later after it's created. You can also disable a service CIDR label for the service gateway at any time.
For traffic to be routed from a subnet in your VCN to a service gateway, you must add a rule accordingly to the subnet's route table. The rule must use the service gateway as the target.

NEW QUESTION 39
How can you provide users access to an existing compartment?
- A. by granting users access to a compartment when the compartment is created
- B. by granting access directly to the user when the user is created
- C. by adding users to a compartment. All users in the compartment will have access to the objects in the compartment.
- D. by adding users to a group and defining a policy to provide the group access to the compartment
Answer: D
Explanation:
Explanation
A policy is a document that specifies who can access which Oracle Cloud Infrastructure resources that your company has, and how. A policy simply allows a group to work in certain ways with specific types of resources in a particular compartment In general, here's the process an IAM administrator in your organization needs to follow:
Define users, groups, and one or more compartments to hold the cloud resources for your organization.
Create one or more policies, each written in the policy language.
Place users into the appropriate groups depending on the compartments and resources they need to work with.
Provide the users with the one-time passwords that they need in order to access the Console and work with the compartments. For more information,

What happens when you run terraform plan?
- A. It deletes all existing resources and re-creates them.
- B. It shows a dependency graph.
- C. It configures, reconfigures, and instantiates resources and their dependencies.
- D. It shows the operator the course of action that would be taken if a change is applied.
Answer: D
Explanation:
Explanation
References:
The terraform plan command is used to create an execution plan. Terraform performs a refresh, unless explicitly disabled, and then determines what actions are necessary to achieve the desired state specified in the configuration files.
This command is a convenient way to check whether the execution plan for a set of changes matches your expectations without making any changes to real resources or to the state. For example, terraform plan might be run before committing a change to version control, to create confidence that it will behave as expected.
NEW QUESTION 41
Which is a customer's responsibility on an Oracle Cloud Infrastructure database?
- A. installing the operating system (OS), Grid Infrastructure, and database software
- B. creating the first default database on the DBCS server
- C. patching the database and OS
- D. creating an ASM diskgroup for data file or temp file storage
Answer: C
Explanation:
Explanation
On autonomous there's no patching needed. But on the regular DB Cloud services you need to patch the DB and the OS. During the creation on the OCDB the first DB is created automatically Oracle automatically takes care of Operating system Installation/Configuration, Grid Infrastructure, ASM diskgroup Creation/Configuration , and database software Installation and first database on the DB System.
that's all when Creating DB Systems. and then the customer responsible to apply the patches to the database and OS
NEW QUESTION 42

What is the recommended approach to create this backup using FSS features?
- A. Compress the data that is in the shared volume and copy it into a different folder on the boot volume disk.
- B. Implement a backup policy to copy data from the shared volume to object storage.
- C. Use the rsync tool to send data from the shared volume to a block volume.
- D. Use the rsync tool to send data from the shared volume to a boot volume disk.
- E. Implement a backup policy to execute a snapshot of the shared volume.
Answer: E
NEW QUESTION 44
You are about to upload log file (5 TiB size) to Oracle Cloud Infrastructure object storage and have decided to use multipart upload capability for a more efficient and resilient upload.
Which two statements are true about multipart upload? (Choose two.)
- A. The maximum size for an uploaded object is 10 TiB
- B. You do not have to commit the upload after you have uploaded all the object parts
- C. Individual object parts can be as small as 10 MiB or as large as 50 GiB
- D. While a multipart upload is still active, you cannot add parts even if the total number of parts is less than
10,000
Answer: A,C
Explanation:
Explanation
With multipart upload, you split the object you want to upload into individual parts. Individual parts can be as large as 50 GiB or as small as 10 MiB. (Object Storage waives the minimum part size restriction for the last uploaded part.) Decide what part number you want to use for each part. Part numbers can range from 1 to
10,000. You do not need to assign contiguous numbers, but Object Storage constructs the object by ordering part numbers in ascending order.
The maximum size for an uploaded object is 10 TiB
While a multipart upload is still active, you can keep adding parts as long as the total number is less than
10,000.
NEW QUESTION 45
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. VM DB systems
- B. Autonomous Transactions Processing (ATP)
- C. bare metal DB systems
- D. Autonomous Data Warehouse (ADW)
Answer: C
Explanation:
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.
NEW QUESTION 46
An Oracle Cloud Infrastructure tenancy administrator is not able to delete a user in the tenancy.
What can cause this issue?
- A. User is member of an Identity and Access Management (IAM) group.
- B. Users can be blocked but not deleted.
- C. User needs to be deleted from federation Identity Provider (IdP) before deleting from IAM.
- D. User has multi-factor authentication (MFA) enabled.
Answer: D
NEW QUESTION 47
Which statement is true regarding Autonomous Transaction Processing (ATP)?
- A. After terminating a database, the database name is available for immediate reuse
- B. A database name cannot be used concurrently for both an Autonomous Data Warehouse (ADW) and an ATP database
- C. A maximum of 2 TB of storage can be enabled for an ATP database
- D. A maximum of 8 cores can be enabled for an ATP database
Answer: B
Explanation:
Explanation
The database name must be unique among all Autonomous Data Warehouses and Autonomous Databases in your tenancy in the same region.
Terminating an Autonomous Transaction Processing database permanently deletes the instance and removes all automatic backups. You cannot recover a terminated database.
the maximum number of CPUs and maximum storage capacity that can be provisioned in Oracle Autonomous Database In the current release up to 128 CPUs and 128TB can be provisioned from the cloud console.
Customers requiring more resources need to call their Oracle account team
NEW QUESTION 48
Which two Oracle Cloud Infrastructure database services allow you to dynamically both scale CPU and storage? (Choose two.)
- A. Autonomous Transaction Processing (ATP)
- B. bare metal DB system
- C. Autonomous Data Warehouse (ADW)
- D. virtual machine DB system
Answer: A,C
Explanation:
Explanation
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 but you can't increase the storage If the original DB system VM shape uses a single node, running databases on the DB system nodes are sequentially stopped and then restarted on the new shape so not dynamic
NEW QUESTION 49
You are running a mission-critical database application in Oracle Cloud Infrastructure (OCI). You take regular backups of your DB system to OCI object storage. Recently, you notice a failed database backup status in the console.
What step can you take to determine the cause of the backup failure?
- A. Ensure that your database host can connect to OCI object storage.
- B. Make sure that the database is not active and running while the backup is in progress.
- C. Don't restart the dcsagent program even if it has a status of stop/waiting.
- D. Ensure the database archiving mode is set to NOARCHIVELOG.
Answer: A
Explanation:
Database backups can fail for various reasons. Typically, a backup fails because either the database host cannot access the object store, or there are problems on the host or with the database configuration.
First need to determining the Problem
In the Console, a failed database backup either displays a status of Failed or hangs in the Backup in Progress or Creating state. If the error message does not contain enough information to point you to a solution, you can use the database CLI and log files to gather more data. Then, refer to the applicable section in this topic for a solution.
Database Service Agent Issues
Your Oracle Cloud Infrastructure Database makes use of an agent framework to allow you to manage your database through the cloud platform. Occasionally you might need to restart the dcsagent program if it has the status of stop/waiting to resolve a backup failure.
Object Store Connectivity Issues
Backing up your database to Oracle Cloud Infrastructure Object Storage requires that the host can connect to the applicable Swift endpoint. You can test this connectivity by using a Swift user.
Host Issues
One or more of the following conditions on the database host can cause backups to fail:
- Interactive Commands in the Oracle Profile
- The File System Is Full
- Incorrect Version of the Oracle Database Cloud Backup Module
- Changes to the Site Profile File (glogin.sql)
Database Issues
An improper database state or configuration can lead to failed backups.
- Database Not Running During Backup
- Archiving Mode Set to NOARCHIVELOG (When you provision a new database, the archiving mode is set to ARCHIVELOG by default. This is the required archiving mode for backup operations)
- Stuck Database Archiver Process and Backup Failures
- Temporary Tablespace Errors
- RMAN Configuration and Backup Failures
- RMAN Retention Policy and Backup Failures
- Loss of Objectstore Wallet File and Backup Failures
TDE Wallet and Backup Failures
- Incorrect TDE Wallet Location Specification
- Incorrect State of the TDE Wallet
- Incorrect Configuration Related to the TDE Wallet
- Missing TDE Wallet File
As this is not new provisioned database and already in the ARCHIVELOG , regular backups of DB system to OCI object storage in places, so the best answers are,
- Ensure that your database host can connect to the OCI object storage
- Restart the database service agent
