A network engineer wants to automate the monitoring of Cisco TelePresence TX systems. Which step should the engineer take first?

Cisco TMS is a management application platform, not a monitoring protocol that needs to be configured on the codec itself as a prerequisite for automation.

Medianet is a Cisco framework for media-aware network optimization and does not provide the device monitoring interface needed for automated polling.

NTP configures time synchronization on the codec, which supports accurate log timestamps but is not the mechanism that enables automated monitoring.

Multiway is a feature for cascading multipoint conferences and has no relevance to monitoring automation.

SNMP is the foundational protocol for network device monitoring and management. Configuring SNMP on the TelePresence codec exposes device metrics, traps, and status information to a network management system, which is the required first step before any automated monitoring or alerting can be established.
