Question 71
Question
You are responsible for setting up access for all the cloud users of a large enterprise. You log in to the Phoenix region and start creating users and policies. You then realize that some users might be creating resources in the Ashburn region.
Which step should you perform to enable those users?
A. You can assign a region to each of the users at the time of creation.
B. IAM users are global and non-admin users can add resources to any region by default.
C. You need to log in to each region separately to create users for that particular region.
D. IAM users are global. As an administrator, make sure that you subscribe to the Ashburn region.
Answer
D. IAM users are global. As an administrator, make sure that you subscribe to the Ashburn region.

Question 73
Question
You are the Solutions Architect of a large company and are tasked with migrating all your services to Oracle Cloud Infrastructure. As part of this, you first design a Virtual Cloud Network (VCN) with a public subnet and a private subnet. Then in order to provide Internet connectivity to the instances in your private subnet, you create an Oracle Linux instance in your public subnet and configure NAT on it. However, even after adding all related security list rules and routes in the Route Table, your private subnet instances still cannot connect to the Internet.
Which action should you perform to enable Internet connectivity?
A. Disable “Source and Destination Check” on the VNIC of your Linux instance.
B. There is no way that a private subnet can connect to the Internet.
C. Create a Dynamic Routing Gateway (DRG) and route your private IP traffic to the DRG.
D. Restart the NAT instance.
Answer
A. Disable “Source and Destination Check” on the VNIC of your Linux instance.
Explanation
By default, every VNIC performs the source/destination check on its network traffic. The VNIC looks at the source and destination listed in the header of each network packet. If the VNIC is not the source or destination, then the packet is dropped.
If the VNIC needs to forward traffic (for example, if it needs to perform Network Address Translation (NAT)), you must disable the source/destination check on the VNIC. For instructions, see To update an existing VNIC. For information about the general scenario, see Using a Private IP as a Route Target.

Question 74
Question
Which service would you use if your big data workload required shared access and NFS-based connectivity?
A. block volume
B. archive storage
C. object storage
D. file storage
Answer
D. file storage
Question 75
Question
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 ?s (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.
Answer
D. Deploy the cluster nodes in a single region and deploy each node in different fault domains within a single AD.
Question 76
Question
Which three are capabilities of the dbaascli utility? (Choose three.)
A. Patching the primary database deployment
B. Open port 1521 in the VCN to allow for traffic to the listener
C. Start and open the database instance
D. Switchover and failover in an Oracle Guard configuration
E. Clone a DB
Answer
A. Patching the primary database deployment
C. Start and open the database instance
D. Switchover and failover in an Oracle Guard configuration
Explanation
Using the dbaascli utility, you can:
- Change the password of a database user.
- Start and stop a database.
- Start and stop the Oracle Net listener.
- Check the status of the Oracle Data Guard configuration.
- Perform switchover and failover in an Oracle Data Guard configuration.
- Patch the database deployment.
- Perform database recovery.
- Rotate the master encryption key.

Question 77
Question
When terminating a compute instance, which statement is true?
A. The instance needs to be stopped first, and then terminated.
B. The boot volume is always deleted.
C. All block volumes attached to the instance are terminated.
D. Users can preserve the boot volume associated with the instance.
Answer
D. Users can preserve the boot volume associated with the instance.
Explanation
You can permanently terminate (delete) instances that you no longer need. Any attached VNICs and volumes are automatically detached when the instance terminates. Eventually, the instance’s public and private IP addresses are released and become available for other instances. By default, the instance’s boot volume is deleted when you terminate the instance, however you can preserve the boot volume associated with the instance, so that you can attach it to a different instance as a data volume, or use it to launch a new instance.
Question 78
Question
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
Answer
C. custom resolver
D. Internet and virtual cloud network (VCN) resolver

B. Archive Storage Service
C. File Storage Service
D. Block Storage Service
Answer
D. Block Storage Service
Question 80
Question
There are multiple options of migrating Oracle Databases from on-premises to Oracle Cloud Infrastructure.
Which two characteristics do you need to consider when choosing a migration method? (Choose two.)

B. On-premises database version and quantity of data, including indexes
C. On-premises host operating system platform and network bandwidth
D. On-premises connectivity using remote and local VCN peering
Answer
