D

The correct answer is D. Junos OS.

Juniper Networks MX Series routers use Junos OS as their operating system. Junos OS is a highly reliable and secure network operating system that is built on top of a FreeBSD UNIX-based kernel. It is a single operating system that runs across all Juniper Networks platforms, including routers, switches, and security devices.

Junos OS provides a modular architecture that enables the software to be easily updated and upgraded. It also provides a consistent operational and configuration interface across all Juniper Networks devices, making it easier for network administrators to manage and troubleshoot their networks.

Some of the key features of Junos OS include:

• A highly modular architecture that enables easy software updates and upgrades without disrupting network operations.
• A rich set of routing protocols, including BGP, OSPF, and ISIS, that enable Juniper Networks devices to interoperate with other networking devices.
• An industry-leading implementation of MPLS (Multiprotocol Label Switching) that enables advanced network services such as VPNs (Virtual Private Networks) and traffic engineering.
• A powerful automation framework, based on the YANG data modeling language and the NETCONF protocol, that enables network administrators to automate many network operations and configurations.
• A comprehensive security framework, including stateful firewalling, intrusion prevention, and IPsec VPN, that helps protect networks from threats and attacks.

Overall, Junos OS is a highly reliable and feature-rich network operating system that enables Juniper Networks devices to deliver high-performance, secure, and scalable networking solutions.
