A network administrator is designing an out-of-band (OOB) management architecture for edge router console access and remote reboot capabilities during a primary network outage. Which of the following solutions should be implemented to achieve full OOB administrative control and power management under these conditions? (Select TWO).
- Connect device RS-232 console ports to a centralized terminal server linked to an auxiliary cellular modem networkCevap
- BDeploy Telnet across primary Ethernet interfaces to maintain low-overhead remote command-line access
- Install a smart switched Power Distribution Unit (PDU) connected to an independent out-of-band management networkCevap
- DEnable SNMPv2c read-write community strings over primary LAN interfaces for remote system resets
Cevap
The correct architecture requires connecting device serial console ports to a terminal server and deploying a smart switched PDU on an independent out-of-band network.
Out-of-band (OOB) management operates independently of the primary production network. Connecting device serial console ports to a terminal server grants command-line interface access even if the primary operating system or network link drops. Furthermore, deploying a smart switched PDU allows remote administrators to power-cycle unresponsive hardware over the dedicated OOB path when software-based reboots are impossible.
