An administrator is upgrading an existing OpenStack deployment from Linux Bridge to OVS. After changing the core_plugin to ML2 and enabling the OVS mechanism driver, tenant networks fail to work. What is the most likely cause?

The OVS agent is not configured or running on the compute nodes.

The Linux Bridge agent is still running and conflicting with OVS.

The core_plugin should be set to OVS instead of ML2.

The VXLAN type driver is not enabled in ml2_conf.ini.

What is the primary difference between a core plugin and a service plugin in OpenStack Neutron?

Core plugins are used for physical networks, while service plugins are used for virtual networks

Core plugins manage L2 connectivity, while service plugins provide advanced network services

Core plugins are open source, while service plugins are proprietary

Core plugins are required, while service plugins are optional

An OpenStack administrator is reviewing the Neutron configuration and sees that the core plugin is set to ML2. They need to understand how ML2 handles different network types such as flat, VLAN, and VXLAN. What is the role of mechanism drivers in this architecture?

They replace the need for the Neutron server.

They provide advanced services like LBaaS and FWaaS.

They define the L2 connectivity mechanisms and interact with the underlying switching hardware or software.

They manage the IP address allocation for tenant networks.

A cloud administrator is deploying a new OpenStack environment and must choose a Neutron networking plugin. The team requires a plugin that supports both VLAN and VXLAN tenant networks, and they want to use the same plugin for both Layer 2 connectivity and to provide security groups. Which plugin should the administrator select?
