You run 5 Oracle Cloud Infrastructure (OCI) Virtual Machine instances on an OCI dedicated virtual host. How will this deployment be billed?
- A. All 5 instances will be billed on the basis of the number of OCPUs
- B. The dedicated virtual machine host all 5 instances, and the boot volume of each instance will be billed
- C. The dedicated virtual machine host and the boot volumes of each instance will be billed
- D. Only the dedicated virtual machine host will be billed
Answer: C
Explanation:
You must create a dedicated virtual machine host before you can place any instances on it. When creating the dedicated virtual machine host, you select an availability domain and fault domain to launch it in. All the VM instances that you place on the host will subsequently be created in this availability domain and fault domain. You also select a compartment when you create the dedicated virtual machine host, but you can move the host to a new compartment later without impacting any of the instances placed on it. You can also create the instances in a different compartment than the dedicated virtual machine host, or move them to difference compartments after they have been launched.
You are billed for the dedicated virtual machine host as soon as you create it, but you are not billed for any of the individual VM instances you place on it. You will still be billed for image licensing costs if they apply to the image you are using for the VM instances.

NEW QUESTION # 78
What two statements regarding the Virtual Cloud Network (VCN) are true?
- A. You can only create one VCN per region.
- B. VCN is a regional resource that span across all the Availability Domains in a Region.
- C. VCN is a global resource that span across all the Regions
- D. A single VCN can contain both private and public Subnets.
- E. The VCN is the IPSec-based connection with a remote on premises location.
Answer: B,D
Explanation:
When you work with Oracle Cloud Infrastructure, one of the first steps is to set up a virtual cloud network (VCN) for your cloud resources.
VIRTUAL CLOUD NETWORK (VCN) :
A virtual, private network that you set up in Oracle data centers. It closely resembles a traditional network, with firewall rules and specific types of communication gateways that you can choose to use. A VCN resides in a single Oracle Cloud Infrastructure region and covers a single, contiguous IPv4 CIDR block of your choice. See Allowed VCN Size and Address Ranges. The terms virtual cloud network, VCN, and cloud network are used interchangeably in this documentation. For more information, see VCNs and Subnets.
SUBNETS :
Subdivisions you define in a VCN (for example, 10.0.0.0/24 and 10.0.1.0/24). Subnets contain virtual network interface cards (VNICs), which attach to instances. Each subnet consists of a contiguous range of IP addresses that do not overlap with other subnets in the VCN. You can designate a subnet to exist either in a single availability domainavailability domain or across an entire region (regional subnets are recommended). Subnets act as a unit of configuration within the VCN: All VNICs in a given subnet use the same route table, security lists, and DHCP options (see the definitions that follow). You can designate a subnet as either public or private when you create it. Private means VNICs in the subnet can't have public IP addresses. Public means VNICs in the subnet can have public IP addresses at your discretion. See Access to the Internet.

Email alerts are sent to users who are subscribed to a budget alert rule, which specifies the percentage or amount of budget consumption that triggers the alert. Email alerts help users monitor and control their cloud spending.
NEW QUESTION # 81
Which feature allows you to logically group and isolate your Oracle Cloud Infrastructure resources?
- A. Identity and Access Management Groups
- B. Compartments
- C. Availability Domain
- D. Tenancy
Answer: B
Explanation:
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.
* User Group can use some resources in the compartment like network resources also they can't create it depend on the policy that assigned
* Remember, a compartment is a logical grouping, not a physical one

Explanation:
OCI Logging service is a highly scalable and fully managed service that allows you to access logs from OCI resources. OCI Logging allows three kinds of logs: Audit, service, and custom logs. You can find more details for each of these logs in the documentation3 OCI Logging service is a centralized single pane of glass for all logs in a tenancy. You can view and search logs on the Logging Search page. When searching logs, you can correlate across many logs simultaneously. For example, you can view results from multiple logs, multiple log groups, or even an entire compartment with one query3 OCI Logging service can index, enrich, and aggregate log data from application. Custom logs are logs that contain diagnostic information from custom applications, other cloud providers, or an on-premises environment. Custom logs can be ingested through the API, or by configuring the Unified Monitoring Agent. You can configure an OCI compute instance/resource to directly upload Custom Logs through the Unified Monitoring Agent. Custom logs are supported in both a virtual machine and bare metal scenario3 OCI Logging service can analyze critical diagnostic information that describes how resources are performing and being accessed. These logs include audit logs related to events emitted by the OCI Audit service, such as API calls or console actions performed by users or services in your tenancy; service logs emitted by OCI native services, such as API Gateway, Events, Functions, Load Balancer, Object Storage, and VCN Flow Logs; and custom logs from your own applications or sources3

NEW QUESTION # 86
Which two should be considered when designing a fault tolerant solution in Oracle Cloud Infrastructure (OCI)?
- A. performing data integrity check when using OCI File Storage Service
- B. using multiple OCI Availability Domains (AD), where available, to deploy your solution
- C. writing custom scripts that will monitor your solution
- D. ensuring your solution components are distributed across OCI Fault Domains
- E. creating a manual cluster of compute instances
Answer: B,D
Explanation:
Creating a manual cluster of compute instances, and Writing custom scripts that will monitor your solution are not valid ways to ensure fault tolerance at all. Also, Performing Data Integrity check when using OCI File Storage Service is not valid since OCI takes care of it.
Therefore, we are left with:
1) Using multiple OCI Availibility Domains (AD), where available, to deploy your solution - Which is excellent because we have multiple AD's so that if one fails, we have a backup AD!
2) Ensuring your solution components are distributed across OCI Fault Domains - So that we can protect our deployment against unexpected power failures, AD failure etc.

NEW QUESTION # 89
What does compute instance vertical scaling mean?
- A. Providing Fault tolerance
- B. Changing to a large or smaller shape
- C. Adding additional compute instances
- D. Enabling Disaster recovery
Answer: B
Explanation:
Changing the Shape of an Instance (Horizontal Scaling)
You can change the shape of a virtual machine (VM) instance without having to rebuild your instances or redeploy your applications. This lets you scale up your Compute resources for increased performance, or scale down to reduce cost.
Autoscaling (vertical scaling)
Autoscaling lets you automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand.
As load increases, instances are automatically provisioned: the instance pool scales out. As load decreases, instances are automatically removed: the instance pool scales in.
