A network engineer is configuring a network management platform that collects high-frequency telemetry data from core switches. The data collector requires a transport protocol that minimizes packet header overhead and does not delay data transmission with connection establishment or acknowledgment tracking. Which of the following features are characteristic of the transport protocol appropriate for this telemetry traffic? (SELECT TWO)
- A fixed 8-byte header structure without fields for sequence numbering or flow controlCevap
- Best-effort data delivery operating without a prior connection establishment handshakeCevap
- CSliding window flow control to adjust transmission rates based on receiver buffer capacity
- DAutomated retransmission requests initiated when missing segments are identified by sequence gaps
- EDirect encapsulation of Layer 2 frames into IP datagrams bypassing transport port assignments
Cevap
The characteristics of the connectionless protocol (UDP) required for high-frequency telemetry are a fixed 8-byte header structure without sequence numbers or flow control, and best-effort data delivery operating without a prior connection handshake.
The scenario describes a telemetry application requiring User Datagram Protocol (UDP), which is connectionless. UDP relies on a fixed 8-byte header containing no sequence numbers, window sizes, or acknowledgment fields, and it sends datagrams using best-effort delivery without establishing a session handshake first.
