Layer 7 — Cisco CCNA (200-301) Practice Questions
Layer 7 refers to the application layer in the OSI seven-layer model, and it is the layer where network-aware applications and protocols operate. The CCNA 200-301 exam tests knowledge of common Layer 7 protocols including DNS, HTTP, HTTPS, FTP, TFTP, SMTP, and SNMP, along with their port numbers and functions. Recognizing which protocols operate at Layer 7 helps network engineers troubleshoot service-level issues and understand how traffic is classified by upper-layer services.
