What is a key benefit of Oracle Cloud Infrastructure Virtual Machine DB Systems?
- A. Support for RAC DB systems
- B. Automated disaster recovery
- C. No need to create database Indices
- D. Automated backups to OCI Block Volume
Answer: A
Explanation:
Explanation
There are two types of DB systems on virtual machines:
A 1-node virtual machine DB system consists of one virtual machine.
A 2-node virtual machine DB system consists of two virtual machines. (RAC) A virtual machine DB system database uses Oracle Cloud Infrastructure block storage instead of local storage.
You specify a storage size when you launch the DB system, and you can scale up the storage as needed at any time.
For 1-node virtual machine DB systems, Oracle Cloud Infrastructure provides have a "fast provisioning" option that allows you to create your DB system using Logical Volume Manager as your storage management software.

Budgets are set on
Cost-tracking tags
Compartments (including the root compartment)
NEW QUESTION 53
Which kind of scaling is supported by virtual machines in Oracle Cloud Infrastructure Compute service?
- A. Only scaling in
- B. Only scaling up or down
- C. Only scaling out
- D. Scaling up or down, and scaling in or out
Answer: D
Explanation:
Explanation
Horizontal scaling means that you scale by adding more machines into your pool of resources whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine.
An easy way to remember this is to think of a machine on a server rack, we add more machines across the horizontal direction and add more resources to a machine in the vertical direction.
With horizontal-scaling it is often easier to scale dynamically by adding more machines into the existing pool
- Vertical-scaling is often limited to the capacity of a single machine, scaling beyond that capacity often involves downtime and comes with an upper limit.
NEW QUESTION 54
What does compute instance horizonal scaling mean?
- A. stopping/starting the instance
- B. adding additional compute instances
- C. changing compute instance size
- D. backing up data to object storage
Answer: B
Explanation:
Explanation
Cloud Horizontal Scaling refers to provisioning additional servers to meet your needs, often splitting workloads between servers to limit the number of requests any individual server is getting. In a cloud-based environment, this would mean adding additional instances instead of moving to a larger instance size.
Cloud Vertical Scaling refers to adding more CPU or memory to an existing server, or replacing one server with a more powerful server.

Answer: B
Explanation:
Explanation
Components of IAM
RESOURCE
The cloud objects that your company's employees create and use when interacting with Oracle Cloud Infrastructure. For example: compute instances, block storage volumes, virtual cloud networks (VCNs), subnets, route tables, etc.
USER
An individual employee or system that needs to manage or use your company's Oracle Cloud Infrastructure resources. Users might need to launch instances, manage remote disks, work with your virtual cloud network, etc. End users of your application are not typically IAM users. Users have one or more IAM credentials (see User Credentials).
GROUP
A collection of users who all need the same type of access to a particular set of resources or compartment.
DYNAMIC GROUP
A special type of group that contains resources (such as compute instances) that match rules that you define (thus the membership can change dynamically as matching resources are created or deleted). These instances act as "principal" actors and can make API calls to services according to policies that you write for the dynamic group.
NETWORK SOURCE
A group of IP addresses that are allowed to access resources in your tenancy. The IP addresses can be public IP addresses or IP addresses from a VCN within your tenancy. After you create the network source, you use policy to restrict access to only requests that originate from the IPs in the network source.
COMPARTMENT
A collection of related resources. Compartments are a fundamental component of Oracle Cloud Infrastructure for organizing and isolating your cloud resources. You use them to clearly separate resources for the purposes of measuring usage and billing, access (through the use of policies), and isolation (separating the resources for one project or business unit from another). A common approach is to create a compartment for each major part of your organization. For more information, see Setting Up Your Tenancy.
TENANCY
The root compartment that contains all of your organization's Oracle Cloud Infrastructure resources. Oracle automatically creates your company's tenancy for you. Directly within the tenancy are your IAM entities (users, groups, compartments, and some policies; you can also put policies into compartments inside the tenancy). You place the other types of cloud resources (e.g., instances, virtual networks, block storage volumes, etc.) inside the compartments that you create.
POLICY
A document that specifies who can access which resources, and how. Access is granted at the group and compartment level, which means you can write a policy that gives a group a specific type of access within a specific compartment, or to the tenancy itself. If you give a group access to the tenancy, the group automatically gets the same type of access to all the compartments inside the tenancy. For more information, see Example Scenario and How Policies Work. The word "policy" is used by people in different ways: to mean an individual statement written in the policy language; to mean a collection of statements in a single, named "policy" document (which has an Oracle Cloud ID (OCID) assigned to it); and to mean the overall body of policies your organization uses to control access to resources.
HOME REGION
The region where your IAM resources reside. All IAM resources are global and available across all regions, but the master set of definitions reside in a single region, the home region. You must make changes to your IAM resources in your home region. The changes will be automatically propagated to all regions. For more information, see Managing Regions.
FEDERATION
A relationship that an administrator configures between an identity provider and a service provider. When you federate Oracle Cloud Infrastructure with an identity provider, you manage users and groups in the identity provider. You manage authorization in Oracle Cloud Infrastructure's IAM service. Oracle Cloud Infrastructure tenancies are federated with Oracle Identity Cloud Service by default.
NEW QUESTION 66
Which of the following services can you control access to via IAM?
- A. Compute Instances
- B. All services including IAM
- C. DB systems
- D. Networking components
Answer: B
Explanation:
Explanation
Oracle Cloud Infrastructure Identity and Access Management (IAM) lets you control who has access to your cloud resources. You can control what type of access a group of users have and to which specific resources.
This section gives you an overview of IAM components and an example scenario to help you understand how they work together.
