NEW QUESTION # 12
How do Azure administrators and developers connect their applications to Oracle databases using Oracle Database Service for Azure?
- A. By learning OCI and working in the OCI Console
- B. By connecting to the Oracle databases using connection strings
- C. By connecting to the Oracle databases using database links
- D. By manually creating complex cross-cloud deployments using the Interconnect
Answer: B
Explanation:
The same way you do in Azure today. Each database resource created by Oracle Database Service for Azure gets an Azure connection string you can use to connect to the database from any Azure application.
During onboarding, Oracle Database Service for Azure creates network connections between the cloud environments.
During database provisioning, Oracle Database Service for Azure defines the DNS entries and connection strings needed to access the resource from Azure.
Azure developers (and applications) don't need to know anything about Oracle Database Service for Azure-all they need is the connection string. Oracle publishes the connection string on the custom dashboard it creates for the database in Azure, so developers don't have to leave the Azure portal to get what they need to access the database from their applications.
Hence, the CORRECT ANSWER is "By connecting to the Oracle databases using connection strings"
NEW QUESTION # 13
Which components are required to establish a Site-to-Site VPN connection in Oracle Cloud Infra-structure?
- A. Internet Gateway, Customer Premises Equipment (CPE), and IPsec tunnel
- B. Internet Gateway (IG), Network Address Translation (NAT) Gateway, and IPsec tun-nel
- C. Dynamic Routing Gateway (DRG), Customer Premises Equipment (CPE), and IPsec tunnel
- D. Dynamic Routing Gateway (DRG), NAT Gateway, and IPsec tunnel
Answer: C
Explanation:
Site-to-Site VPN Components:
CPE OBJECT: At your end of Site-to-Site VPN is the actual device in your on-premises network (whether hardware or software). The term customer-premises equipment (CPE) is commonly used in some industries to refer to this type of on-premises equipment.
DYNAMIC ROUTING GATEWAY (DRG): At Oracle's end of Site-to-Site VPN is a virtual router called a dynamic routing gateway, which is the gateway into your VCN from your on-premises network.
IPSEC CONNECTION: After creating the CPE object and DRG, you connect them by creating an IPSec connection, which you can think of as a parent object that represents the Site-to-Site VPN.
TUNNEL: An IPSec tunnel is used to encrypt traffic between secure IPSec endpoints. Oracle cre-ates two tunnels in each IPSec connection for redundancy.
So, Internet Gateway, NAT Gateway are NOT valid Site-to-Site VPN Components.
Hence, Dynamic Routing Gateway (DRG), Customer Premises Equipment (CPE), and IPsec tunnel is the CORRECT answer.
NEW QUESTION # 14
Which is NOT an Azure resource that is created when you provision a database using Oracle Data-base Service for Azure?
- A. Log Analytics workspace
- B. Application Insights workspace
- C. Oracle Database Service
- D. Custom Dashboard workspace
Answer: C
Explanation:
Log Analytics Workspace, Application Insights and Custom Dashboard are Azure resources and hence we can eliminate these options.
We are left with Oracle Database Service which is the CORRECT answer.
NEW QUESTION # 15
What is the primary purpose of an Oracle Cloud Infrastructure Identity Domain?
- A. Establish a secure, private connection between the tenancy and other Oracle Cloud ser-vices.
- B. Provide a centralized location for storing and managing user credentials and access.
- C. Define the roles and privileges assigned to a user or group of users within the tenancy.
- D. Create isolated networks for resources within the tenancy for enhanced security.
Answer: B
Explanation:
Oracle Cloud Infrastructure (OCI) Identity Domain is the access control plane for Oracle Cloud. An identity domain is a container for managing users and roles, federating and provisioning of users, secure application integration through Oracle Single Sign-On (SSO) configuration, and SAML and OAuth based Identity Provider administration.
NEW QUESTION # 16
A consulting company that employs Oracle Cloud Infrastructure (OCI) architects has successfully completed resource migration from Microsoft Azure to OCI, and no longer requires the Oracle FastConnect circuit to Azure. The project manager has asked you to delete all resources involved in this cross-cloud connectivity. From the Azure side, you delete the Resource Group. After a while, you notice that all Azure resources have been deleted, except for the Azure ExpressRoute circuit.
What could be a potential reason for this issue?
- A. You need to remove the Azure ExpressRoute Partner Service Key from the Oracle FastConnect circuit, and then you can delete the ExpressRoute virtual circuit.
- B. Your bill from the OCI side needs to be paid in full before you can remove the Azure ExpressRoute circuit.
- C. You need to first delete the Oracle FastConnect circuit for the ExpressRoute circuit to be decommissioned, and then you can delete the ExpressRoute virtual circuit.
- D. You need to remove all routes that point to the cross-cloud connection on both OCI and Azure before you can delete the circuit.
Answer: C
Explanation:
To delete the interconnect, perform these steps in the order given. Failure to do so results in a failed state ExpressRoute circuit.
1. Delete the ExpressRoute connection. Delete the connection by selecting the Delete icon on the page for your connection.
2. Delete the Oracle FastConnect circuit from the Oracle Cloud Console.
3. Once the Oracle FastConnect circuit has been deleted, you can delete the Azure Ex-pressRoute circuit.
Hence "You need to first delete the Oracle FastConnect circuit for the ExpressRoute circuit to be decommissioned, and then you can delete the ExpressRoute virtual circuit." is the CORRECT AN-SWER.

Autonomous Database on shared Exadata infrastructure: DOES NOT require an Azure VNeT
NEW QUESTION # 18
What components are required for setting up an Azure VNet to Oracle Cloud Infrastructure VCN connection as part of the OCI-Azure Interconnect?
- A. An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached internet gateway
- B. An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached NAT gateway
- C. An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached dynamic routing gateway
- D. An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached service gateway
Answer: C
Explanation:
If you closely look at the options, you can start eliminating some of them.
We can easily eliminate "An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached service gateway" as we don't require service gateway to setup OCI-Azure Interconnect.
On similar lines, we can also eliminate the options where internet gateway and NAT gateway is pre-sent.
Hence "An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with sub-nets and an attached internet gateway" and "An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached NAT gateway".
As you can see in the architecture below, on the OCI side you require a Dynamic Routing Gate-way and on the Azure side you need a Virtual Network Gateway.
Hence the option "An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached dynamic routing gateway" is CORRECT.
NEW QUESTION # 19
What is a key benefit of using Oracle Autonomous Database on Shared Exadata Infrastructure?
- A. Unlimited storage capacity
- B. Automatic database tuning and patching
- C. Dedicated hardware resources for each database
- D. Seamless integration with third-party cloud providers

- A. Transport Layer Security (TLS)
- B. Secure Sockets Layer (SSL)
- C. Datagram Transport Layer Security (DTLS)
- D. Internet Protocol Security (IPSec)
Answer: D
Explanation:
Site-to-Site VPN provides a site-to-site IPSec connection between your on-premises network and your virtual cloud network (VCN). The IPSec protocol suite encrypts IP traffic before the packets are transferred from the source to the destination and decrypts the traffic when it arrives.
NEW QUESTION # 21
An enterprise has a workload running in a VNet in Microsoft Azure and a database running in a VCN in Oracle Cloud Infrastructure. The enterprise wants to set up a private, secure, and isolated network connection between the two clouds to enable traffic flow between the workload and the database. Which option can be used to achieve this requirement?
- A. Use Azure Private Link to create a private connection between the workload and the database.
- B. Use Azure VPN and Oracle FastConnect to establish a private and secure tunnel be-tween the Azure VNet and the OCI VCN.
- C. Use Azure ExpressRoute and Oracle FastConnect to create a private interconnection between the Azure VNet and the OCI VCN.
- D. Use public internet to establish connectivity between the Microsoft Azure VNet and the OCI VCN.
Answer: C
Explanation:
As per the question, the keywords are "The enterprise wants to set up a private, secure, and isolat-ed network connection between the two clouds" Use public internet to establish connectivity between the Microsoft Azure VNet and the OCI VCN - INCORRECT as this option won't provide private, secure and isolated connection.
Use Azure VPN and Oracle FastConnect to establish a private and secure tunnel between the Azure VNet and the OCI VCN is INCORRECT as it won't provide a isolated connection.
Use Azure Private Link to create a private connection between the workload and the database is INCORRECT as Azure Private Link enables you to access Azure PaaS Services (for example, Azure Storage and SQL Database) and Azure hosted customer-owned/partner services over a pri-vate endpoint in your virtual network.
Use Azure ExpressRoute and Oracle FastConnect to create a private interconnection between the Azure VNet and the OCI VCN. is CORRECT. To create an integrated multi-cloud experience, Microsoft and Oracle offer direct interconnection between Azure and Oracle Cloud Infrastructure (OCI) through ExpressRoute and FastConnect. Through the ExpressRoute and FastConnect inter-connection, customers can experience low latency, high throughput, private direct connectivity be-tween the two clouds.
NEW QUESTION # 22
Which type of traffic is NOT supported by the OCI-Azure Interconnect?
- A. Traffic between an Azure VNet and peered OCI VCNs in the same region
- B. Traffic between an Azure VNet and an OCI VCN
- C. Traffic between an Azure VNet and peered OCI VCNs in different regions
- D. Traffic between an on-premises network and Azure VNet through the OCI VCN
Answer: D
Explanation:
You can connect your VNet and VCN so that traffic that uses private IP addresses goes over the cross-cloud connection.
The connection enables traffic to flow from the VNet through the connected VCN to a peered VCN in the same Oracle Cloud Infrastructure region, or a different region.
The Cross-cloud connection does not enable traffic between your on-premises network through the VCN to the VNet, or from your on-premises network through the VNet to the VCN.
NEW QUESTION # 23
What should you do to prepare your Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) for potential security risks when connected to a Microsoft Azure VNet?
- A. Allow all traffic from the Azure VNet without restrictions.
- B. Disable the connection between Azure VNet and OCI VCN.
- C. Remove all OCI security rules.
- D. Limit all inbound and outbound traffic from the Azure VNet to expected and well-defined traffic.
Answer: D
Explanation:
Controlling Traffic Flow Over the Connection
Even if a connection has been established between your VCN and VNet, you can control the packet flow over the connection with route tables in your VCN. For example, you can restrict traf-fic to only specific subnets in the VNet.
Controlling the Specific Types of Traffic Allowed
It's important that you ensure that all outbound and inbound traffic with the VNet is intended or expected and well defined. Implement Azure network security group and Oracle security rules that explicitly state the types of traffic one cloud can send to the other and accept from the other.
NEW QUESTION # 24

NEW QUESTION # 26
Which is true regarding fully automated and guided onboarding for the OracleDB for Azure ser-vice?
- A. Fully automated onboarding requires more permissions to be granted than guided onboarding.
- B. An Azure user who completes fully automated onboarding can log in to the OracleDB for Azure portal, but cannot deploy and provision databases.
- C. An Azure user who completes guided onboarding cannot log in to the OracleDB for Azure portal.
- D. Guided onboarding is simpler and faster than fully automated onboarding.
Answer: A
Explanation:
The fully-automated onboarding option for OracleDB for Azure is faster and more convenient than the guided account linking. Hence the option "Guided onboarding is simpler and faster than fully automated onboarding" is NOT TRUE.
When the automated configuration finishes, OracleDB for Azure is fully operational. The Azure user that completed onboarding can login and use the OracleDB for Azure portal to deploy and provision databases for use in their Azure environment. Hence the option "An Azure user who completes fully automated onboarding can log in to the OracleDB for Azure portal, but cannot de-ploy and provision databases" is NOT TRUE.
If you used the guided onboarding process, the user who completed onboarding can login to the OracleDB for Azure portal, but not really do anything there. Before users can do anything produc-tive using OracleDB for Azure, you must first complete configuration steps for each user or user group. Hence the option "An Azure user who completes guided onboarding cannot log in to the Or-acleDB for Azure portal" is NOT TRUE.
Now, let's look at the only option left which is "Fully automated onboarding requires more permis-sions to be granted than guided onboarding". This option is TRUE as the automated onboarding process requires that the Azure user onboarding to OracleDB for Azure have at least one of the fol-lowing admin roles: Application Administrator, Cloud Application Administrator, Privileged Role Administrator, or Global Administrator. Guided onboarding is provided for customers who do not want to grant OracleDB for Azure all the Azure permissions required for fully automated onboard-ing. Hence this is the correct answer.
