to Increase disk performance by using NVMe disks you can use Dense IO Shape also as the number of CPUs will not change so we should VM.DenseIO2.16
NEW QUESTION 20
Which two statements about the Oracle File Storage Service (FSS) Security are accurate? (Choose two.)
- A. Data in transit to an FSS mount target is encrypted.
- B. Oracle IAM controls which filesystems are mountable by which instances.
- C. FSS leverages UNIX user group and permission checking for file access security.
- D. Encryption of file storage in FSS is optional.
- E. Security lists can be used as a virtual firewall to prevent an instance from mounting an FSS mount target within a subnet.
Answer: A,C
Explanation:
Explanation
All data is encrypted at rest. and In-transit encryption provides a way to secure your data between instances and mounted file systems using TLS v. 1.2 (Transport Layer Security) encryption.
File Storage service supports the AUTH_UNIX style of authentication and permission checking for remote NFS client requests.
NEW QUESTION 21
Which statement is true about the Oracle Cloud Infrastructure File Storage Service Mount Target?
- A. Mount target has a public IP address and DNS name
- B. You can access multiple file systems through a single mount target
- C. Each mount target requires six internal IP addresses in the subnet to function
- D. Mount target lives in a single subnet of your choice, but is not highly available
Answer: B
Explanation:
A mount target is an NFS endpoint that lives in a VCN subnet of your choice and provides network access for file systems. The mount target provides the IP address or DNS name that is used together with a unique export path to mount the file system. A single mount target can export many file systems. Typically, you create your first mount target and export when you create your first file system. The mount target maintains an export set which contains all of the exports for its associated file systems.
Limitations and Considerations
Each availability domain is limited to two mount targets by default. However, you can export up to 100 file systems through each mount target.
See Service Limits for a list of applicable limits and instructions for requesting a limit increase.
Each mount target requires three internal IP addresses in the subnet to function. Two of the IP addresses are used during mount target creation. The third IP address must remain available for the mount target to use for high availability failover.
The File Storage service doesn't "reserve" the third IP address required for high availability failover. Use care when designing your subnets and file systems to ensure that sufficient IP addresses remain available for your mount targets.

NEW QUESTION 25
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 29
You are managing a tier-1 OLTP application on an Autonomous Transaction Processing (ATP) database. Your business needs to run hourly batch processes on this ATP database that may consume more CPUs than what is available on the server.
How can you limit these batch processes to not interfere with the OLTP transactions?
- A. ATP is designed for OLTP workload only; you should not run batch processes on ATP
- B. Disable automated backup during the batch process operations
- C. Copy OLTP data into new tables in a new table space and run batch processes against these new tables
- D. Configure ATP resource management rules to manage runtime and IO consumption for the consumer group of batch processes
Answer: D
Explanation:
Explanation
Autonomous Transaction Processing comes with predefined CPU/IO shares assigned to different consumer groups. You can modify these predefined CPU/IO shares if your workload requires different CPU/IO resource allocations.
By default, the CPU/IO shares assigned to the consumer groups TPURGENT, TP, HIGH, MEDIUM, and LOW are 12, 8, 4, 2, and 1, respectively. The shares determine how much CPU/IO resources a consumer group can use with respect to the other consumer groups. With the default settings the consumer group TPURGENT will be able to use 12 times more CPU/IO resources compared to LOW, when needed. The consumer group TP will be able to use 4 times more CPU/IO resources compared to MEDIUM, when needed.
