During a routine network scan, a security administrator discovered an unidentified service running on a new embedded and unmanaged hvac controller, which is used to monitor the company's datacenter:
t161/udp open
162/udp open
163/tcp open
the enterprise monitoring service requires snmp and snmptrap connectivity to operate.
which of the following should the security administrator implement to harden the system?
a. patch and restart the unknown services.
b. segment and firewall the controller's network
c. disable the unidentified service on the controller.
d. implement snmpv3 to secure communication.
e. disable tcp/udp ports 161 through 163

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

What precautions should you take to prevent injuries when dealing with heavy loads?

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.
