Difficulty: EasyPhysical Security Controls and Environmental Measures

A network administrator receives an automated threshold notification indicating that ambient heat in a remote wiring closet has risen above 30∘C30^\circ\text{C} (86∘F86^\circ\text{F}). Which physical environmental monitoring component is directly responsible for measuring atmospheric conditions and triggering this alert?

  3. C
    Time-domain reflectometer cable tester
  4. D
    SNMPv3 cryptographic authentication agent

Answer

An environmental temperature sensor probe is directly responsible for measuring ambient atmospheric heat and sending automated threshold notifications.
Environmental temperature sensor probes are dedicated hardware devices placed inside server rooms and equipment racks to measure ambient temperature and relative humidity continuously. When temperatures surpass defined thresholds (such as 30∘C30^\circ\text{C}), these probes alert management platforms (e.g., via SNMP traps) so administrators can intervene before hardware suffers thermal damage.

Step-by-Step Solution

1
Identify the primary function required in the scenario.
The requirement is measuring ambient physical closet conditions (temperature) and generating an automated alert when exceeding preset parameters (30∘C30^\circ\text{C}).
Physical environmental monitoring systems rely on specialized hardware sensors deployed near racks and equipment to monitor temperature, humidity, water leakage, and airflow.
2
Evaluate the candidate components against physical security and environmental control roles.
The temperature sensor probe continuously monitors atmospheric conditions and integrates with management software to issue alerts when thermal thresholds are breached.
Correctly identifying hardware sensors ensures proactive maintenance before overheating causes thermal throttling or hardware damage.
