The correct answer is D: HTTPS. HTTPS and SSH are the correct answers. SSH (port 22) provides secure encrypted CLI access to network devices and is a primary management protocol that must be available and responsive even during congestion.

Question

While designing quality of service policies, which two types of traffic must be prioritized as management traffic? (Choose two )

Options

ASCP
BICMP
CRADIUS
DHTTPS
ESSH

Explanation

HTTPS and SSH are the correct answers. SSH (port 22) provides secure encrypted CLI access to network devices and is a primary management protocol that must be available and responsive even during congestion. HTTPS (port 443) provides secure web-based management access to device GUIs and management platforms. Both are critical management plane protocols and should be marked and queued in a dedicated management traffic class with guaranteed bandwidth. SCP (Secure Copy) is used for file transfers (e.g., IOS image uploads) and is not a real-time management protocol requiring strict prioritization. ICMP is used for diagnostics (ping/traceroute) but is low-priority. RADIUS handles authentication but is typically handled at the control plane level and does not require the same strict QoS priority as interactive management sessions.
