When migrating workloads from AWS to OCI, which connectivity option generally offers the LOWEST latency and HIGHEST bandwidth for data transfer, assuming a direct, dedicated connection is financially viable?

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?

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 10.0.2.0/24 subnet to the VCN Local Peering Gateway. What is the most probable cause?

Your company utilizes a hybrid cloud architecture, connecting its on-premises network to an OCI VCN using a FastConnect private peering connection. You need to ensure that instances within a specific subnet in the VCN can only communicate with resources in a designated IP address range within the on-premises network. What is the MOST effective way to achieve this specific network isolation?

You are designing a multicloud architecture where your customer wants to leverage OCI for its cost- effective compute and storage, while utilizing Microsoft Azure’s AI/ML services and AWS’s extensive serverless capabilities. The application requires low latency and high bandwidth between the clouds. Which of the following approaches provides the LEAST optimal solution for interconnecting these three cloud providers for production workloads?

You are troubleshooting a network connectivity issue between a compute instance in a private subnet within your VCN and a service on the public internet using Cloud Shell. You suspect a problem with the network security group (NSG) rules associated with the instance's VNIC. Which Cloud Shell command and appropriate tool combination allows you to directly inspect the NSG configuration impacting the VNIC?

You're automating the creation of multiple VCNs across different OCI regions using Cloud Shell scripting. Which authentication method within Cloud Shell is best suited to programmatically authenticate with OCI, ensuring both security and scalability for this automation task?

When configuring inter-tenancy VCN peering, what is the purpose of the "peer ID" provided by the requesting tenancy to the accepting tenancy?

A financial services company is implementing a multicloud strategy, storing sensitive customer data in OCI due to its enhanced security features, running analytics workloads in AWS, and utilizing a SaaS application hosted in Google Cloud Platform (GCP). To comply with stringent data sovereignty regulations, the company requires that all traffic between OCI and AWS must transit exclusively within the United States. Which is the MOST critical consideration when choosing a connectivity solution to ensure compliance?

You are managing a critical application hosted on OCI. To enhance security, you have enabled DNSSEC for your domain using OCI DNS. You want to automate the process of monitoring the health and validity of your DNSSEC configuration and receive alerts if any issues are detected. Which OCI service can be MOST effectively used for this DNSSEC monitoring purpose?
