1z0-1115-23 Practice Exam Questions with Answers Oracle Cloud Infrastructure 2023 Multicloud Architect Associate Certification

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.

Explanation

By using Oracle FastConnect and Azure ExpressRoute, customers can seamlessly build a private interconnection between their OCI and Microsoft Azure environments. The Interconnect also ena-bles joint customers to take advantage of a unified identity and access management platform that leads to cost savings. Cloud engineers can set up SSO between Microsoft Azure and OCI for their Oracle applications, such as PeopleSoft, JD Edwards EnterpriseOne, and E-Business Suite. Having a federated SSO makes the integration seamless and allows users to authenticate only once to access multiple applications, without signing in separately to access each application.

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.

Explanation

The exchange of routes is accomplished by industry standard BGP routing protocol.

Explanation

See the screenshots below for the databases mentioned in the question:

You can see the Azure Virtual Network option for Base Database, MySQL Database with Heat-Wave and Oracle Exadata Database.

Base Database: Requires Azure Virtual Network

MySQL Database with HeatWave: Requires Azure Virtual Network

Explanation

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.

Explanation

Network security groups (NSGs) act as a virtual firewall for your compute instances .

An NSG consists of a set of ingress and egress security rules that apply only to a set of VNICs of your choice in a single VCN (for example: all the compute instances that act as web servers in the web tier of a multi-tier application in your VCN).

Hence, "Use Network Security Groups to apply specific firewall rules for each component." is the CORRECT answer.

In this question , you can straightaway reject "Use Virtual Cloud Networks to create isolated net-works for each component." and "Use Route Tables to define custom routing policies between each component." options.

NSG wins here due to the keywords "restrict communication between these components" in the question. A network security group (NSG) provides a virtual firewall for a set of cloud re-sources that all have the same security posture.
