Question 3

when choosing testing equipment, you should choose them based on the test results required by the standards you’re using to certify the network - TRUE or FALSE?

Answer 3

TRUE

Question 4

Which copper hardware tester can determine if the wires are going to the right pins?

Answer 4

wire-map tester

Question 5

What type of issue do wire-map testers not detect and what type of test would detect it?

Answer 5

Split pairs. Near-end cross talk test should detect split pairs

Question 6

cable testers can tell if a cable can pass ethernet data at network speeds. TRUE or FALSE?

Answer 6

FALSE, it can only test for simple things like opens, shorts and crossed pairs

Answer 8

whether your network meets specific ISO or TIA standards Cat5e to 7.

Question 9

What hardware device tests the following:

• speed and condition of cable
• how long it takes to send a signal down a cable and back again
• cable impedance
• splice connector locations
• estimated cable length

Question 13

Which device is more practical and saves time to use instead of a toner probe?

Answer 13

wire-map tester

Question 14

What are two important benefits of baselining and recording metrics over time using hardware testing tools?

Answer 14

1) to see if a problem has gotten better or worse

2) to determine if interventions you’ve taken to improve a scenario have worked

Question 15

what is a key metric for network baselining using hardware tools?

Answer 15

Error rate
