A. Using a DNS hostname that resolves to the floating private IP address of the active MySQL Database Service instance.

B. Using the public IP address of the MySQL Database Service instance.

C. Using the private IP address of the primary MySQL Database Service instance directly.

D. Using a Service Gateway to connect to the MySQL Database Service endpoint.

正確答案: A

問題2

You are managing an OCI Network Firewall that protects a VCN with multiple subnets. The application team reports intermittent connectivity issues to a specific application server behind the firewall. You suspect the issue might be related to the firewall's stateful inspection. What would be the most efficient way to troubleshoot if the stateful inspection is causing these connectivity issues?

A. Create a Network Firewall policy with a specific rule that allows all traffic to/from the affected application server, bypassing inspection.

B. Recreate the Network Firewall with a completely different configuration.

C. Disable stateful inspection on the entire Network Firewall to check if the connectivity is restored.

D. Review the Network Firewall logs for denied traffic originating from or destined to the application server.

正確答案: D

問題3

You are designing an OCI networking architecture for a multi-tier application using Infrastructure as Code (IaC). The architecture includes an OKE cluster for the front-end, a set of Compute instances for the back- end, and an Autonomous Database. You want to ensure that all traffic between these components is encrypted. You are using Transport Layer Security (TLS) for end-to-end encryption but are concerned about the overhead of encrypting all traffic within the VCN. Which approach provides the MOST balanced approach to security and performance, minimizing the overhead of encryption while still protecting sensitive data?

A. Implement TLS encryption only between the OKE cluster and the load balancer. Rely on the inherent security of the OCI network for traffic within the VCN.

B. Implement mutual TLS (mTLS) for all traffic between the OKE cluster, the Compute instances, and the Autonomous Database.

C. Implement TLS encryption for traffic between the OKE cluster and the Compute instances and use Oracle Database Vault to encrypt data at rest and in transit for the Autonomous Database.

D. Use Network Security Groups (NSGs) and Security Lists to control access between components but do not implement any additional encryption within the VCN.

問題4

When establishing cross-tenancy connectivity using Remote Peering Connections (RPCs), which IAM policy statement is essential to grant the requesting tenancy the ability to initiate the connection?

A. Allow group <group_name> to manage virtual-network-family in tenancy=<target_tenancy_OCID>

B. Allow group <group_name> to use remote-peering-connections in tenancy=<target_tenancy_OCID>

C. Allow group <group_name> to inspect virtual-network-family in tenancy=<target_tenancy_OCID>

D. Allow group <group_name> to read remote-peering-connections in tenancy=<target_tenancy_OCID>

問題5

Your company has deployed a mission-critical application on OCI that requires consistent, predictable network performance. You have established a FastConnect circuit to connect your on-premises data center to OCI. You observe that the network latency varies throughout the day, and you suspect that other traffic is impacting the performance of your application. Which FastConnectfeature can you leverage to prioritize traffic for your mission-critical application and improve its network performance?

A. FastConnect Quality of Service (QoS)

B. FastConnect Jumbo Frames

C. FastConnect VLAN Tagging

D. FastConnect BGP Communities

正確答案: A

問題6

Your company needs to establish a secure connection between your on-premises network and OCI for a pilot project. The project has a limited budget and requires a quick setup, but also demands that the connection is encrypted. The long-term plan involves migrating to FastConnect, but that will take several months. Which OCI VPN solution would be most suitable for this short-term, budget-conscious, and security-aware scenario?

A. Use a Dynamic Routing Gateway (DRG) with a Site-to-Site VPN connection configured using dynamic routing with BGP.

B. Deploy a third-party virtual appliance VPN solution from the OCI Marketplace within a public subnet and configure a VPN connection to your on-premises network.

C. Use a Service Gateway to connect to a third-party VPN service available on the internet.

D. Use a Dynamic Routing Gateway (DRG) with a Site-to-Site VPN connection configured using static routing.

問題7

In a Zero Trust network architecture, what is the primary purpose of implementing micro-segmentation within OCI VCNs?

A. To reduce the number of required route tables.

B. To simplify inter-region connectivity.

C. To increase network bandwidth.

D. To limit the blast radius of potential security breaches.

問題8

You are designing a microservices-based application on OCI. Each microservice is deployed as a container in Oracle Container Engine for Kubernetes (OKE). You want to expose these microservices through a single entry point using a Layer 7 load balancer and route traffic based on the request path. Which OCI load balancing integration method with OKE is the MOST appropriate and efficient?

A. Manually create a Regional Load Balancer and configure backend sets with the private IP addresses of the Kubernetes worker nodes hosting the microservices.

B. Deploy a Kubernetes NodePort service for each microservice and configure an OCI NetworkLoad Balancer to forward traffic to the NodePort services on the worker nodes.

C. Deploy a Kubernetes LoadBalancer service, which automatically provisions an OCI Regional Load Balancer to distribute traffic to the microservice pods.

D. Deploy a Kubernetes Ingress controller that leverages an OCI Regional Load Balancer to route traffic to the microservice pods based on Ingress rules.

問題9

You have successfully enabled DNSSEC on your OCI DNS zone and provided the DS record to your domain registrar. However, when you test your DNS configuration using online DNSSEC validation tools, you are still seeing errors indicating that DNSSEC validation is failing. What is the most likely reason for this failure?

A. The DNSSEC algorithm used by OCI DNS is not supported by the validation tools.

B. The OCI DNS resolver is not configured to validate DNSSEC signatures.

C. The domain registrar has not yet published the DS record in the parent zone, preventing the chain of trust from being established.

D. The Time To Live (TTL) value for your DNS records is too low, causing validation errors.

正確答案: C

問題10

You are troubleshooting a BGP peering issue between your on-premises router and an OCI FastConnect virtual circuit. You have verified the physical connectivity and confirmed that the BGP session is established.
However, routes are not being exchanged. You suspect a problem with the BGP configuration. What is the MOST LIKELY cause of this issue, assuming the basic BGP configuration (AS numbers, peer IP addresses) is correct?

A. There is a mismatch in the BGP authentication keys between the on-premises router and OCI.

B. The MTU (Maximum Transmission Unit) size is mismatched, causing fragmentation and packet loss.

C. The advertised prefixes are being filtered by a prefix list or route map on either the on-premises router or the OCI FastConnect virtual circuit.

D. The BGP keepalive timers are misconfigured, causing the session to drop intermittently.
