An enterprise is migrating a legacy application that relies on VLAN-based segmentation and static routing to a cloud environment that uses an SDN with overlay networking and dynamic routing. The application's network configuration is hardcoded in the application code. What is the most important compatibility consideration before migration?

Whether the SDN supports the same maximum transmission unit (MTU) size as the legacy network.

Whether the SDN controller supports the same routing protocol as the legacy environment.

Whether the application can be modified to use logical network identifiers instead of VLAN IDs.

Whether the cloud provider offers a VPN gateway for hybrid connectivity.

Which characteristic is typical of a centralized SDN environment?

The control plane is distributed across all forwarding devices

The data plane is separated from the forwarding plane

Each switch makes independent forwarding decisions

A single controller manages the network's control plane

Which capability is a direct result of network programmability in SDN?

Elimination of all network monitoring

Manual configuration of each switch individually

Increased physical hardware requirements

Automated provisioning of network paths via software

When assessing the compatibility of an existing network appliance with a target SDN environment, which factor is most critical?

The appliance's power supply type

The appliance's physical dimensions

The appliance's support for standard SDN protocols like OpenFlow

An organization is migrating a workload that uses a legacy network security appliance that only supports VLAN-based segmentation. The target SDN environment uses overlay networking with VXLAN and does not support VLANs on the virtual switches. The security team requires the same segmentation between application tiers. Which approach best meets the requirement?

Deploy a physical VLAN-aware switch in the cloud to preserve the legacy segmentation.

Use network ACLs on the virtual switches to replicate the segmentation.

Replace the legacy appliance with a virtual security appliance that supports VXLAN and integrates with the SDN controller.

Configure the SDN controller to map VLANs to VXLAN network identifiers.
