Sample Questions for Oracle 1Z0-1124-25 Exam Preparation

Question 1

You are designing a multi-tier application within an OCI Virtual Cloud Network (VCN). The application comprises a public-facing web tier in one subnet, an application tier in another, and a database tier in a third. For security reasons, you want to ensure that only the application tier can initiate connections to the database tier. The web tier needs to be able to communicate with the application tier, but not directly with the database tier. You are using private IP addresses within your VCN. Which procedural step is MOST effective to achieve this network isolation?

ACreate separate Network Security Groups (NSGs) for each tier and configure ingress and egress rules to restrict traffic accordingly. Configure the route table for the Web Tier subnet to route traffic destined for the Database Tier subnet through the Application Tier.

BCreate a single Network Security Group (NSG) and associate it with all three subnets. Configure ingress and egress rules within the single NSG to restrict traffic accordingly.

CCreate separate security lists for each subnet and configure ingress and egress rules to restrict traffic accordingly. Create appropriate route rules in each subnet's route table.

DCreate separate security lists for each subnet and configure ingress and egress rules to restrict traffic accordingly. Configure the route table for the Web Tier subnet to route traffic destined for the Database Tier subnet through the Application Tier.

Correct : C

Requirements: App tier only initiates to DB; web tier to app tier only.

Option A: NSGs with forced routing through app tier adds complexity and latency---less effective.

Option B: Single NSG lacks subnet-level isolation---incorrect.

Option C: Separate security lists per subnet with ingress/egress rules enforce isolation; route tables ensure proper VCN routing---correct and effective.

Option D: Security lists are good, but routing web-to-DB via app tier is unnecessary---incorrect.

Conclusion: Option C achieves isolation efficiently.

Oracle states:

'Use separate security lists per subnet with ingress/egress rules to isolate tiers. Route tables manage intra-VCN traffic without forced hops.'

This supports Option C. Reference: Security Lists Overview - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Concepts/securitylists.htm).

Question 2

Your company needs to connect an on-premises data center to an OCI Virtual Cloud Network (VCN) to extend their existing infrastructure to the cloud. The connection MUST be secure, reliable, and provide consistent, low-latency access to resources in both environments. Resources in the OCI VCN need access to the on-premises servers, and resources in the on-premises data center need to access the compute instances located in a private subnet within the OCI VCN. Which is the MOST appropriate architectural design for establishing connectivity in this hybrid cloud environment, considering the available endpoints and gateway options in OCI?

AImplement a Site-to-Site VPN connection between the on-premises network and the OCI VCN, utilizing a Dynamic Routing Gateway (DRG) in OCI.

BEstablish a FastConnect connection between the on-premises network and the OCI VCN, utilizing a Dynamic Routing Gateway (DRG) in OCI.

CConfigure a public endpoint for each resource in the OCI VCN that needs to be accessed from the on-premises network.

DImplement a FastConnect connection from the on-premises network to the OCI VCN utilizing a Dynamic Routing Gateway (DRG) in OCI and implement a Site-to-Site VPN connection as backup.

Correct : D

Requirements: Secure, reliable, low-latency, bidirectional access with redundancy.

Option A: VPN via DRG is secure but lacks low latency and redundancy---insufficient.

Option B: FastConnect via DRG offers low latency and security but no redundancy---partial fit.

Option C: Public endpoints are insecure and high-latency---incorrect.

Option D: FastConnect for primary low-latency access, VPN as backup for redundancy---correct and most appropriate.

Conclusion: Option D meets all criteria.

Oracle states:

'FastConnect with DRG provides secure, low-latency hybrid connectivity. Add a Site-to-Site VPN for redundancy to ensure reliability.'

This supports Option D. Reference: Hybrid Cloud Connectivity - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/hybridcloud.htm).
