Which two Junos platforms provide stateful firewall functionality? (Choose two.)

MX Series routers offer advanced services, including stateful firewall capabilities, often through dedicated services cards, to provide security features alongside routing.

EX Series switches primarily focus on Ethernet switching and routing, offering stateless firewall filters, but not comprehensive stateful firewall functionality as a core feature.

SRX Series devices are purpose-built security platforms, and stateful firewall is their primary and most fundamental security feature.

QFX Series switches are high-performance data center and campus switches focused on switching and routing, and do not offer full stateful firewall capabilities.
