9

What is the ideal humidity range for computer equipment?

40 to 60%

10

Is condensation or corrosion caused by lower or higher humidity?

higher

11

What increases the potential for ESD? Lower or higher humidity?

Lower

12

What are two types of electrical noise?

- Electromagnetic Interference (EMI)
- Radio Frequency Interference (RFI)

13

What are the two types of EMI?

- Common Made Noise
- Traverse Mode Noise

14

How is common made noise caused?

by different charges between hot and ground

15

How is traverse mode caused?

caused by a difference in power between the hot and neutral wires

16

What is RFI caused by?

Short drop in voltage

22

In electric anomaly terms what is a Inrush?

Initial power rush

23

In electric anomaly terms what is a spike?

Momentary rush of power

24

In electric anomaly terms what is a surge?

Prolonged rush of power

Natural Access Control
Natural Surveillance
Territorial Re-inforcement

30

Which CPTED strategy uses security zones (or defensible space) to limit or restrict movement and differentiate between public, semi private and private areas that require differing levels of protection?

Natural Access Control
