  4. D
    Web server

Cevap

Spam filter
A spam filter acts as an email security host positioned at the network edge to analyze incoming messaging traffic, identify spam, phishing, and malware threats, and relay clean messages to internal mail servers.

Adım Adım Çözüm

1
Analyze the operational requirements specified in the scenario.
The appliance must inspect inbound communication, filter out phishing and malicious attachments, and forward safe messages.
Identifying the targeted application payload and security objective narrows down the host service.
2
Map the required functionality to network server roles.
Perimeter inspection and blocking of unwanted email traffic is the core function of a spam filter / mail gateway.
Infrastructure services like DNS, DHCP, and Web hosting operate at different layers or fulfill unrelated administrative roles.
