Eva wants to deploy a network security device that will provide firewall services as well as IPS and email filtering. Which device should she deploy?

A unified threat management (UTM) device combines multiple security services including firewall, IDS or IPS, antivirus/antimalware, email filtering, WAF, and similar services into a single solution. An FWSM, or firewall service module, is an older Cisco chassis-based firewall; a WAF is a web application firewall; and an ELB is Elastic Load Balancer, a load-balancing service available via AWS.
