Zorluk: KolayRemote Access and Out-of-Band Management

A network technician needs to perform the initial configuration on a brand-new managed switch that has no IP address assigned to its interfaces. Which of the following connection methods should the technician use to access the device command-line interface?

  1. Local console connectionCevap
  2. B
    Secure Shell (SSH) session
  3. C
    Telnet session
  4. D
    Remote Desktop Protocol (RDP) connection

Cevap

Local console connection
A local console connection provides direct out-of-band management access using a serial interface connection. It allows initial configuration of network devices when no IP address or network connectivity has been established.

Adım Adım Çözüm

1
Determine the network operational status of the new switch.
The device is unconfigured and has no IP address assigned to any interface.
Network-layer remote management protocols require IP addressing to establish connectivity.
2
Evaluate access protocols against the current state.
In-band protocols (SSH, Telnet, RDP) cannot reach an unconfigured device.
In-band management depends on an operational network protocol stack.
3
Select a direct physical management connection.
Use a serial console cable connected directly from the technician workstation to the switch console port.
Console management operates out-of-band and works without IP addressing.
