NEW QUESTION 61
You need to create a high performance shared file system, and have been advised to use file storage service (FSS). You have logged into the Oracle Cloud Infrastructure console, created a file system, and followed the steps to mount the shared file system on your Linux instance. However, you are still unable to access the shared file system from your Linux instance.
What is the likely reason for this?
- A. There are no security list rules for mount target traffic
- B. There is no Identity and Access Management (IAM) policies set up to allow you to access the mount target
- C. There is no route in your virtual cloud network's (VCN) route table for mount target traffic
- D. There is no internet gateway (IGW) set up for mount target traffic
Answer: A
Explanation:
Explanation
Virtual firewall rules for your VCN. Your VCN comes with a default security list, and you can add more.
These security lists provide ingress and egress rules that specify the types of traffic allowed in and out of the instances. You can choose whether a given rule is stateful or stateless. Security list rules must be set up so that clients can connect to file system mount targets. For more information about how security lists work in Oracle Cloud Infrastructure, see Security Lists in the Networking documentation. For information about setting up specific security list rules required for mount target traffic, see Configuring VCN Security List Rules for File Storage. About Security explains how security lists interact with other types of security in your file system.

Which two Oracle Cloud Infrastructure database services allow you to dynamically both scale CPU and storage? (Choose two.)
- A. Autonomous Data Warehouse (ADW)
- B. bare metal DB system
- C. Autonomous Transaction Processing (ATP)
- 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 65
Which two parameters are required in a back end set's HTTP health check? (Choose two.)
- A. status code

What happens when you run terraform plan?
- A. It configures, reconfigures, and instantiates resources and their dependencies.
- B. It shows a dependency graph.
- C. It shows the operator the course of action that would be taken if a change is applied.
- D. It deletes all existing resources and re-creates them.
Answer: C
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 76
Which of the following statement is true regarding Oracle Cloud Infrastructure Object Storage Pre-Authenticated Requests?
- A. Changing the bucket visibility does not change existing pre-authenticated requests
- B. Pre-authenticated requests don't have an expiration
- C. It is not possible to create pre-authenticated requests for the buckets, but only for the objects
- D. It Is not possible to create pre-authenticated requests for "archive" storage tier
Answer: A
Explanation:
Pre-authenticated requests provide a way to let users access a bucket or an object without having their own credentials, as long as the request creator has permissions to access those objects. For example, you can create a request that lets an operations support user upload backups to a bucket without owning API keys. Or, you can create a request that lets a business partner update shared data in a bucket without owning API keys.
When you create a pre-authenticated request, a unique URL is generated. Anyone you provide this URL to can access the Object Storage resources identified in the pre-authenticated request, using standard HTTP tools like curl and wget.
Understand the following scope and constraints regarding pre-authenticated requests:
Users can't list bucket contents.
You can create an unlimited number of pre-authenticated requests.
There is no time limit to the expiration date that you can set.
You can't edit a pre-authenticated request. If you want to change user access options in response to changing requirements, you must create a new pre-authenticated request.
The target and actions for a pre-authenticated request are based on the creator's permissions. The request is not, however, bound to the creator's account login credentials. If the creator's login credentials change, a pre-authenticated request is not affected.
You cannot delete a bucket that has a pre-authenticated request associated with that bucket or with an object in that bucket.
Understand the following scope and constraints regarding public access:
Changing the type of access is bi-directional. You can change a bucket's access from public to private or from private to public.
Changing the type of access doesn't affect existing pre-authenticated requests. Existing pre-authenticated requests still work.
