References: https://docs.cloud.oracle.com/iaas/Content/File/Concepts/filestorageoverview.htm The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases, including the following: General Purpose File Storage: Access to an unlimited pool of file systems to manage growth of structured and unstructured data. Big Data and Analytics: Run analytic workloads and use shared file systems to store persistent data. Lift and Shift of Enterprise Applications: Migrate existing Oracle applications that need NFS storage, such as Oracle E-Business Suite and PeopleSoft. Databases and Transactional Applications: Run test and development workloads with Oracle, MySQL, or other databases. Backups, Business Continuity, and Disaster Recovery: Host a secondary copy of relevant file systems from on premises to the cloud for backup and disaster recovery purposes. MicroServices and Docker: Deliver stateful persistence for containers. Easily scale as your container- based environments grow.

Correct Answer: C

A public IP address is an IPv4 address that is reachable from the internet. If a resource in your tenancy

needs to be directly reachable from the internet, it must have a public IP address. Depending on the type

of resource, there might be other requirements.

There are two types of public IPs:

Ephemeral: Think of it as temporary and existing for the lifetime of the instance. Reserved: Think of it as

persistent and existing beyond the lifetime of the instance it's assigned to. You can unassign it and then

reassign it to another instance whenever you like. Exception: reserved public IPs on public load balancers.

To create a new reserved public IP in your pool

Confirm you're viewing the region and compartment where you want to create the reserved public IP.

Open the navigation menu. Under Core Infrastructure, go to Networking and click Public IPs.

Click Create Reserved Public IP.

Enter the following:

Name: An optional friendly name for the reserved public IP. The name doesn't have to be unique, and you

can change it later. Avoid entering confidential information.

Compartment: Leave as is.

Tags:Optionally, you can apply tags. If you have permissions to create a resource, you also have

permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to

use the tag namespace. For more information about tagging, see Resource Tags. If you are not sure if you

should apply tags, skip this option (you can apply tags later) or ask your administrator.

Click Create Reserved Public IP.

To assign a reserved public IP to a private IP

Prerequisite: The private IP must not have an ephemeral or reserved public IP already assigned to it. If it

does, first delete the ephemeral public IP, or unassign the reserved public IP. Confirm you're viewing the

compartment that contains the instance with the private IP you're interested in.

Open the navigation menu. Under Core Infrastructure, go to Compute and click Instances.

Click the instance to view its details.

Under Resources, click Attached VNICs.

The primary VNIC and any secondary VNICs attached to the instance are displayed.

Click the VNIC you're interested in.

Under Resources, click IP Addresses.

The VNIC's primary private IP and any secondary private IPs are displayed. For the private IP you're

interested in, click the Actions icon (three dots), and then click Edit. In the Public IP Address section, for

Public IP Type, select the radio button for Reserved Public IP.

Enter the following:

Compartment: The compartment that contains the reserved public IP you want to assign. Reserved Public

IP: The reserved public IP you want to assign. You have three choices:

Create a new reserved public IP. You may optionally provide a friendly name for it. The name doesn't have

to be unique, and you can change it later. Avoid entering confidential information. Assign a reserved public

IP that is currently unassigned.

Move a reserved public IP from another private IP.

Click Update.
