NEW QUESTION # 61
What two statements regarding the Virtual Cloud Network (VCN) are true?
- A. A single VCN can contain both private and public Subnets.
- B. VCN is a global resource that span across all the Regions
- C. The VCN is the IPSec-based connection with a remote on premises location.
- D. You can only create one VCN per region.
- E. VCN is a regional resource that span across all the Availability Domains in a Region.
Answer: A,E
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.

Which TWO are valid regarding the Oracle Cloud Infrastructure (OCI) Logging service?
(Choose all correct Answers)
- A. It can analyze critical diagnostic information that describes how resources are performing and being accessed.
- B. It enables you to monitor cloud resources using metrics and alarms.
- C. It is a centralized single pane of glass for all logs in a tenancy.
- D. It enables you to analyze cloud resources using custom metrics.
- E. It can index, enrich, and aggregate log data from application.
Answer: A,C
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 # 64
Which TWO are valid regarding Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) peering?
(Choose all correct answers)
- A. Peered VCNs need to be part of the same OCI tenancy.
- B. Peered VCNs can exist in different OCI regions.
- C. A VCN peering connection is a VPN based connection.
- D. Peered VCNs can exist in the same OCI region.
- E. Peered VCNs can have overlapping classless inter-domain routing (CIDR).
Answer: B,D
Explanation:
VCN peering is the process of connecting multiple virtual cloud networks (VCNs) so that their resources can communicate using private IP addresses. There are four types of VCN peering: 1 Local VCN peering: This is the process of connecting two VCNs in the same region and tenancy. This type of peering uses local peering gateways (LPGs) in each VCN to establish a logical connection.
Remote VCN peering: This is the process of connecting two VCNs in different regions, either in the same tenancy or different tenancies. This type of peering uses remote peering gateways (RPGs) in each VCN to establish a logical connection.
Peering VCNs in the same region through a dynamic routing gateway (DRG): This is the process of connecting multiple VCNs in the same region and tenancy by attaching them to a common DRG. A DRG is a virtual router that provides a path for private network traffic between your VCN and other networks.
Peering VCNs in different regions through a DRG: This is the process of connecting multiple VCNs in different regions and tenancies by attaching them to a common DRG and using IPSec VPN or FastConnect to connect the DRGs across regions.
Peered VCNs cannot have overlapping CIDRs, as this would cause routing conflicts and ambiguity. Peered VCNs need to have unique CIDRs that do not overlap with each other or with any other network that they need to communicate with1 A VCN peering connection is not a VPN-based connection. A VPN-based connection is a secure and encrypted connection between your on-premises network and your OCI VCN over the public internet by using IPSec VPN or FastConnect. A VPN-based connection requires an internet gateway or a DRG in your VCN and a customer-premises equipment (CPE) device in your on-premises network2 Peered VCNs do not need to be part of the same OCI tenancy, as long as they are in different regions. Remote VCN peering supports cross-tenancy connections, meaning that you can peer a VCN in one tenancy with a VCN in another tenancy, as long as they are subscribed to the same regions and have proper IAM policies to allow peering. Local VCN peering and peering through a DRG only support intra-tenancy connections, meaning that you can only peer VCNs within the same tenancy1

NEW QUESTION # 67
Which three components are part of Oracle Cloud Infrastructure (OCI) identity and access management service?
- A. Virtual Cloud Networks
- B. Roles
- C. Users
- D. Compute Instances
- E. Regional Subnets
- F. Policies
- G. Dynamic Groups
Answer: C,F,G
Explanation:
Components of IAM
IAM uses the components described in this section. To better understand how the components fit together, see Example Scenario.
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 # 68
Which of the following is INVALID regarding the Oracle Cloud Infrastructure (OCI) Identity Domains?
- A. Identity domains are created inside of a compartment.
- B. Each OCI account includes a default identity domain.
- C. Customers cannot create additional identity domains.
- D. An identity domain represents users and groups in OCI.
Answer: D
NEW QUESTION # 69
What purpose does an Oracle Cloud Infrastructure (OCI) Dynamic Routing Gateway Serve?
- A. Enables OCI Compute instance to connect to on-promises environments
- B. Enables OCI Compute Instance to privately connect to OCI Object Storage
- C. Enables OCI Compute instances to be reached from internet
- D. Enable OCI Compute instances to connect to the internal
Answer: A
Explanation:
You can think of a Dynamic Routing Gateway (DRG) as a virtual router that provides a path for private traffic (that is, traffic that uses private IPv4 addresses) between your VCN and networks outside the VCN's region.
For example, if you use an IPSec VPN or Oracle Cloud Infrastructure FastConnect (or both) to connect your on-premises network to your VCN, that private IPv4 address traffic goes through a DRG that you create and attach to your VCN. For scenarios for using a DRG to connect a VCN to your on-premises network, see Networking Scenarios. For important details about routing to your on-premises network, see Routing Details for Connections to Your On-Premises Network.
Also, if you decide to peer your VCN with a VCN in another region, your VCN's DRG routes traffic to the other VCN over a private backbone that connects the regions (without traffic traversing the internet). For information about connecting VCNs in different regions, see Remote VCN Peering (Across Regions).
NEW QUESTION # 70
You have a mission-critical application which requires to be globally available at all times.
Which deployment strategy should you adopt?
- A. Use multiple Fault Domains In each Availability Domain in each Region.
- B. Use multiple Fault Domains In one Region.
- C. Use multiple Availability Domains In one Region.
- D. Use multiple Fault Domains in any Availability Domain in multiple Regions.
Answer: A
Explanation:
Oracle Cloud Infrastructure is hosted in regions and availability domains. A region is a localized geographic area, and an availability domain is one or more data centers located within a region. A region is composed of one or more availability domains.
Regions are independent of other regions and can be separated by vast distances-across countries or even continents.
Availability domains are isolated from each other, fault tolerant, and very unlikely to fail simultaneously. Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region.
Fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance event that affects one fault domain does not affect instances in other fault domains. In addition, the physical hardware in a fault domain has independent and redundant power supplies, which prevents a failure in the power supply hardware within one fault domain from affecting other fault domains.

NEW QUESTION # 78
A customer wants to use Oracle Cloud Infrastructure (OCI) storing application backups which can be stored for months, but retrieved immediately based on business needs. Which OCI storage service can be used to meet this requirement?
- A. Archive Storage
- B. Object Storage (standard)
- C. Block Volume
- D. File Storage
Answer: B
Explanation:
Oracle Cloud Infrastructure offers two distinct storage class tiers to address the need for both performant, frequently accessed "hot" storage, and less frequently accessed "cold" storage. Storage tiers help you maximize performance where appropriate and minimize costs where possible.
Use Object Storage for data to which you need fast, immediate, and frequent access. Data accessibility and performance justifies a higher price to store data in the Object Storage tier.
Use Archive Storage for data to which you seldom or rarely access, but that must be retained and preserved for long periods of time. The cost efficiency of the Archive Storage tier offsets the long lead time required to access the data.
Unlike Object Storage, Archive Storage data retrieval is not instantaneous.
