A network engineer is configuring a resilient remote access and out-of-band (OOB) management solution for network hardware installed at an unstaffed edge data center. The implementation must ensure administrators maintain management access to device consoles and can power-cycle unresponsive equipment during a complete failure of the primary WAN link. Which TWO of the following components should be deployed to meet these operational requirements? (Select TWO.)
- An out-of-band terminal server connected to device serial console ports and equipped with an independent cellular modemCevap
- Smart switched Power Distribution Units (PDUs) reachable via the dedicated out-of-band management networkCevap
- CIn-band Telnet sessions configured directly on primary WAN router interfaces to allow lightweight CLI access
- DSNMPv2c polling across public internet connections to continuously monitor device power status and system health
Cevap
The correct deployments are an out-of-band terminal server connected to serial console ports with an independent cellular modem, and smart switched Power Distribution Units (PDUs) connected to the out-of-band management network.
Out-of-band (OOB) management relies on physically isolated alternate communication paths. Connecting hardware serial console ports to a terminal server backed by an independent cellular modem preserves command-line access during primary network transport cuts. Additionally, switched PDUs allow administrators to execute remote power-cycling of frozen equipment over the OOB pathway when soft reboots cannot execute.
