Zorluk: KolayUtilizing Hardware Testers and Packet Analyzers

A network technician needs to inspect live network traffic and decode packet headers passing through a server's network interface to troubleshoot an application issue. Which of the following tools are packet analyzers designed for this task? (Select TWO.)

  1. tcpdumpCevap
  2. WiresharkCevap
  3. C
    Loopback plug
  4. D
    Tone generator and probe kit

Cevap

tcpdump and Wireshark are both packet analyzers capable of capturing and inspecting network protocol traffic.
tcpdump and Wireshark are software packet analyzers that intercept, log, and decode raw network frames from a network interface.

Adım Adım Çözüm

1
Identify the required functional capability in the scenario.
The requirement is to capture network frames and inspect protocol headers.
Determining whether physical electrical testing or upper-layer protocol analysis is needed guides tool selection.
2
Evaluate the candidate tools based on operating layer and purpose.
tcpdump and Wireshark operate at the protocol analysis level, whereas tone probes and loopback plugs operate at the physical hardware testing level.
Hardware testing tools evaluate physical layer continuity and signal paths but cannot decode packet contents.

Anahtar Kavram

Packet analyzers (or protocol analyzers) capture and decode protocol data units across network layers, whereas hardware physical testers verify physical media and interface hardware.
