Answer 15

Sensor

Question 16

Used to set off an alarm when temperature reaches dangerous conditions

Answer 16

Major Temperature Threshold

Question 17

Captures the entire packet, including the header and the payload for all traffic entering and leaving a network

Answer 17

Full Packet Capture

Question 18

Relies on a flow collector to record metadata and statistics about network traffic rather than recording each frame

Answer 18

Flow Analysis

Question 19

Defines a particular traffic flow based on the different packets that share the same characteristics

Answer 19

NetFlow

Answer 23

Drop

Question 24

Used to count Selective Packet Discards (SPD) that have occurred

Answer 24

Flush

Question 25

Drops low priority packets when the CPU is too busy so it can save capacity for higher priority packets as a form of QoS

Answer 25

Selective Packet Discards (SPD)

Answer 29

Frame

Question 30

Used to count how often the interface was unable to receive traffic due to an insufficient hardware buffer

Answer 30

Overrun

Question 31
