Other certification materials providers often include outdated or removed questions by Oracle in their Oracle 1Z0-1115-23 exam. These outdated questions lead to customers failing their Oracle Cloud Infrastructure 2023 Multicloud Architect Associate exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Oracle 1Z0-1115-23 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
Which is true regarding fully automated and guided onboarding for the OracleDB for Azure ser-vice?
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.
How do Azure administrators and developers connect their applications to Oracle databases using Oracle Database Service for Azure?
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'
What is the primary difference between using Oracle FastConnect with an Oracle partner and using FastConnect with colocation with Oracle?
FastConnect: With an Oracle Partner:
You can establish a FastConnect connection from your on-premise or remote data center to the data center where your Oracle Cloud resources are provisioned by requesting cloud connectivity services from any of Oracle's FastConnect partners. Oracle has integrated the FastConnect service with a geographically diverse set of IP, VPN, and Ethernet network providers and cloud exchanges to make it easy for you to establish a connection to Oracle Cloud services.
FastConnect: Colocation with Oracle:
If you have purchased colocation space from a data center provider, you can use Oracle FastCon-nect to establish connectivity from your network equipment in that colocation facility to your Oracle Cloud services provisioned at this location. Oracle will provide you a letter of authorization (LOA) that the data center provider will need in order to establish a direct cross-connect into Oracle's FastConnect edge devices provider will need in order to establish a direct cross
An organization has decided to implement a multicloud solution by using Microsoft Azure for their frontend data analytics applications and Oracle Cloud Infrastructure (OCI) for their backend Oracle Autonomous Data Warehouse. In this scenario, how can the organization ensure secure and low la-tency data transfer between the frontend applications and the backend data warehouse?
In the question, frontend is in Azure and backend is in OCI. And the keywords are SECURE and LOW LATENCY data transfer.
Use public internet connections to transfer data between Azure and OCI, encrypting the data in transit - INCORRECT as this option won't provide LOW LATENCY data transfer (as it is us-ing public internet).
Leverage a VPN Gateway to create an encrypted tunnel between Azure and OCI for secure data transfer - INCORRECT as Site-to-Site VPN Connection won't provide LOW LATENCY data transfer as the connection traverses through public internet.
Implement a hybrid cloud approach by integrating on-premises infrastructure with both Azure and OCI - INCORRECT as there is no mention of on-premises environment in the question. This option is irrelevant here.
Establish a dedicated, private connection between Azure and OCI using Azure ExpressRoute and Oracle FastConnect - CORRECT as it provides a direct Interconnect between OCI and Microsoft Azure which in turn provides <2ms latency for superior multicloud network performance.
A company has deployed a multi-tier application in Oracle Cloud Infrastructure (OCI), with web servers in a public subnet and database servers in a private subnet. The database servers need to ac-cess data from OCI Object Storage, and the company wants to ensure that this communication is secure and not exposed to the public internet. Which OCI feature should be used to achieve this objective?
A service gateway lets your virtual cloud network (VCN) privately access specific Oracle services without exposing the data to the public internet. No internet gateway or NAT gateway is required to reach those specific services.
The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the Oracle service travels over the Oracle network fabric and never traverses the internet.
