A development team has deployed a three-tier application in an OCI VCN. The application consists of a public-facing web tier, an application tier, and a database tier. The team reports that the web tier instances can communicate with the application tier instances, but the application tier instances cannot connect to the database tier instances. All security lists are configured to allow all traffic within the VCN. Which OCI Networking diagnostic tool would BEST help you quickly isolate the root cause of this connectivity issue?

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?

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?

Your application running on OCI Compute instances in a private subnet requires high availability and the ability to distribute incoming traffic across multiple instances. You need to ensure that the load balancer can handle both HTTP and HTTPS traffic and provides health checks to monitor the availability of your backend servers. Which OCI Load Balancer offering is the most suitable for this scenario, considering both functionality and cost-effectiveness for a production environment?
정답: B

You are troubleshooting a connectivity issue between two compute instances within the same VCN. Both instances are in different subnets. Instance A (IPv4: 10.0.1.10, IPv6: fc00:1:1::10) can ping its subnet gateway (10.0.1.1) and can ping the IPv6 address of Instance B (fc00:1:2::20), but cannot ping Instance B's IPv4 address (10.0.2.20). The security lists and network security groups (NSGs) are configured to allow all traffic between the subnets. The route table for Instance A's subnet has a rule to route all traffic destined to 10.0.2.0

You have configured an IPSec VPN tunnel over your FastConnect circuit to OCI. You are experiencing intermittent connectivity issues and notice that the VPN tunnel is flapping (frequently going up and down).
You have verified the IKE and IPSec configuration and confirmed that the security policies are correct.
Which is a LESS likely cause of the VPN tunnel flapping when using IPSec over FastConnect, compared to using IPSec over the public internet?

Your company has two FastConnect circuits connecting your on-premises network to OCI. You want to implement a BGP configuration that ensures that traffic from OCI to your on-premises network is load- balanced across both FastConnect circuits. Which BGP configuration would BEST achieve load balancing across the two FastConnect circuits?

Your company is utilizing a multi-cloud architecture with applications running on both OCI and AWS. You have established a Site-to-Site VPN connection between OCI and AWS for secure communication. Over time, you observe that the VPN tunnel becomes unstable and frequently disconnects, particularly during peak hours.
You suspect this is due to increased network latency and packet loss. Which action is least likely to improve the stability and reliability of your OCI-AWS Site-to-Site VPN connection in this scenario?

You are designing an OCI VCN for a new application with the following requirements: The application servers in a private subnet must be able to download software updates from public repositories on the internet; the application servers must NOT be directly accessible from the public internet; the application servers must also be able to access Oracle Cloud Infrastructure Registry (OCIR) within the same region to pull container images. Which combination of VCN Gateways BEST meets these requirements?
