Your company is setting up a FastConnect connection with a provider. You have purchased a port from the provider, and they are requesting information to set up the connection to Oracle Cloud Infrastructure. They specifically require information to configure the VLANs. What information regarding VLAN configuration is ESSENTIAL for them to successfully establish the FastConnect circuit?

A.

The list of all VCN CIDR blocks and their associated tags.

B.

A single unused VLAN ID, your BGP ASN, and the BGP peering IP addresses you want to use.

C.

The MTU (Maximum Transmission Unit) size for all VNICs in your OCI tenancy.

D.

Your Oracle Cloud Identifier (OCID) and compartment ID.

Your organization is migrating workloads to a multicloud environment using OCI, AWS, and Azure. You have applications that require access to on-premises resources and must maintain high security standards. Which connectivity configuration would provide the MOST secure and reliable access while adhering to best practices for a hybrid multicloud architecture?

A.

Establishing IPSec VPN tunnels from the on-premises network directly to each cloud provider (OCI, AWS, and Azure), terminating on the respective cloud provider’s virtual network gateways

B.

Using public internet connectivity for all cloud providers and relying on application-level security measures

C.

Creating a private network connection to OCI using FastConnect, then extending the network to AWS and Azure using a software-defined WAN (SD-WAN) solution that supports end-to-end encryption and policy-based routing

D.

Connecting on-premises to OCI using FastConnect and building VPN tunnels from OCI to Azure and AWS

Which OCI resource is used to establish private connectivity between two VCNs within the same region, facilitating direct, low-latency communication?

A.

Dynamic Routing Gateway (DRG)

B.

Local Peering Gateway (LPG)

C.

Internet Gateway

D.

Service Gateway

Your company uses OCI Certificates to manage SSL/TLS certificates for its public-facing applications. You need to implement a solution that automatically renews these certificates before they expire to avoid service disruptions. Which OCI Certificates feature or configuration best achieves this?

A.

Manually renew the certificates through the OCI Console before their expiration date.

B.

Enable "Automatic Renewal" option within the OCI Certificates service and ensure DNS validation is properly configured.

C.

Use OCI Vault to store the certificates and manually renew them using the Vault API.

D.

There is no automatic renewal feature in OCI Certificates; manual renewal is always required.

Which OCI service provides detailed logs for network traffic traversing a Network Load Balancer, offering insights into client connections and backend health checks?

A.

Flow Logs

B.

Service Logs

C.

Load Balancer Logs

D.

Audit Logs

Which OCI service or feature is best suited for capturing and analyzing network traffic metadata to identify anomalies and troubleshoot connectivity issues between VCN resources?

A.

Network Security Groups (NSGs)

B.

Flow Logs

C.

Route Tables

D.

Service Gateway

Your company utilizes a hybrid cloud architecture, connecting its on-premises network to an OCIVCN 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?

A.

Configure an Internet Gateway for the subnet with a route rule to the on-premises network.

B.

Modify the VCN’s default security list to restrict traffic to the on-premises IP address range.

C.

Create a custom route table for the subnet with a route rule pointing to the Dynamic Routing Gateway (DRG) and configure network security groups (NSGs) to limit traffic to the specified on-premises IP address range.

D.

Configure a Local Peering Gateway (LPG) for the subnet to route traffic to the on-premises network.

Which OCI feature allows the DRG to dynamically learn routes from on-premises networks, facilitating automated route propagation to connected VCNs?

A.

Service Gateway

B.

Local Peering Gateway (LPG)

C.

Border Gateway Protocol (BGP)

D.

Internet Gateway

You are tasked with migrating a critical, latency-sensitive application from Azure to OCI. Due to compliance requirements, all data must be encrypted in transit. Which connectivity option provides the BEST combination of security and performance for this migration?

A.

Configure a Site-to-Site VPN between Azure’s Virtual Network Gateway and OCI’s Dynamic Routing Gateway (DRG), relying on the built-in IPSec encryption

B.

Utilize Azure ExpressRoute and OCI FastConnect through a colocation provider, then implement application-level encryption using TLS

C.

Leverage Azure Data Factory to transfer data to OCI Object Storage via HTTPS

D.

Employ Azure VPN Gateway in conjunction with an OCI Load Balancer with SSL termination for the incoming connections from Azure

In the context of OCI's Zero Trust Packet Routing, which principle emphasizes the necessity of explicitly defining and enforcing access controls at every stage of network communication?

A.

Implicit Trust

B.

Least Privilege

C.

Perimeter Security

D.

Network Segmentation
