How to pass the ETA TTT exam

  • TTT is written for physical security work: expect camera bandwidth sums, NVR uplinks, PoE budgets and long camera runs rather than data center topics.
  • Learn the IEEE PoE types in volts and watts (802.3af, 802.3at, 802.3bt Types 3 and 4) and practise switch power budget arithmetic.
  • Know what each tester proves: a continuity tester checks the wire map, a qualification tester checks link quality and speed, and ping and online tools check packet loss, latency and bandwidth.
  • 75 questions in 2 hours is 96 seconds each, and you need 75%. Bring a non-programmable calculator for bandwidth, dB budgets and PoE sums.

Sample questions with answers

These are the questions in the free test above, with answers. Try the test first. You'll learn more by getting some wrong.

1. A PoE switch feeds 24 IP cameras, each streaming about 6 Mb/s, and has a 100 Mb/s uplink to the NVR. What is the problem?
Answer: The 144 Mb/s total exceeds the uplink; use a 1 Gb/s uplink. The uplink carries every camera's stream at once: 24 x 6 = 144 Mb/s, more than a 100 Mb/s link can carry, so video drops frames. Size uplinks for the total load plus headroom, here a gigabit copper or fiber uplink. Switches forward streams; they don't compress them.
2. An owner wants to watch 4 cameras remotely at 2 Mb/s each. The site's internet service is 100 Mb/s down and 5 Mb/s up. What limits remote viewing?
Answer: The 5 Mb/s upload, below the 8 Mb/s the four streams need. Remote viewing sends video out of the site, so the upload speed matters: 4 x 2 = 8 Mb/s needs more than the 5 Mb/s available. Options are a faster upload, lower-bitrate substreams for remote viewing, or fewer cameras at once. The download speed matters only for traffic coming in.
3. A gigabit IP camera link must run 1.2 km over an existing 62.5/125 µm (OM1) multimode fiber. Will standard 1000BASE-SX transceivers work?
Answer: No; SX on OM1 reaches only about 275 m, so use single-mode. 1000BASE-SX reaches only about 220 to 275 m on 62.5 µm fiber because modal dispersion limits bandwidth. The 2 km figure is 100BASE-FX at a lower data rate. For 1.2 km use single-mode fiber with 1000BASE-LX or similar transceivers rated for that distance.
4. A nonconductive fiber cable will run vertically in a shaft between floors, not in an air-handling space. What is the minimum NEC listing it needs?
Answer: OFNR (riser). Vertical runs in shafts between floors need riser-rated cable: OFNR for nonconductive fiber. Plenum OFNP may substitute, but riser is the minimum. OFNG is for general use on one floor, OFCR is for cable with metallic members, and unlisted cable is limited to 50 ft inside the building.
5. A technician says an 850 nm multimode CCTV transceiver is safe to look into because only a faint red glow is visible. What is the correct response?
Answer: Disagree; most of the 850 nm power is invisible, so use a meter. The eye barely sees 850 nm, so the faint glow hides how much power is actually entering the eye and the blink reflex may not protect it. Never look into a fiber or transceiver port; check for light with a power meter or a video probe. VCSELs at 850 nm are lasers too.
6. A pre-polished cleave-and-crimp connector tests high loss, and a visual fault locator shows a bright glow at the connector body. What is the most likely cause?
Answer: The fiber is not butted cleanly against the internal stub fiber. Cleave-and-crimp connectors work like a mechanical splice: the field fiber must be cleaved well and pushed fully against a factory stub fiber in index-matching gel. A poor cleave or short insertion leaves a gap that leaks light, which the VFL shows. Re-strip, recleave and re-terminate.
7. A pair of 850 nm multimode CCTV transceivers has a 10 dB optical budget. The link has 1.2 km of fiber at 3.5 dB/km, 4 connector pairs at 0.75 dB and 1 mechanical splice at 0.3 dB. Will it work, and with what margin?
Answer: Yes, with about 2.5 dB of margin. Loss is 1.2 x 3.5 = 4.2 dB of fiber, 3.0 dB of connectors and 0.3 dB for the splice, 7.5 dB in total. The budget is 10 dB, so the margin is 2.5 dB. Leaving out the fiber loss gives 6.7 dB; compare total loss with the budget, not one part of it.
8. Fiber transceivers rated 0 to 50 °C will go in an unheated pole-mounted box where winter nights reach -30 °F. What should the installer do?
Answer: Use units rated about -40 to +75 °C or a heated enclosure. -30 °F is about -34 °C, far below the 0 °C minimum, so the transmitter power and receiver sensitivity can drift out of specification or the units can fail. Choose industrial-temperature units (commonly -40 to +75 °C) or a heated, rated enclosure. Insulation alone does not keep an unpowered box warm.
9. A building has old Category 3 cable to each door. Can it carry 1000BASE-T to new IP access control readers?
Answer: No; Cat 3 is rated to 16 MHz and suits 10BASE-T. Category 3 is rated to 16 MHz and supports 10BASE-T; 1000BASE-T needs at least Category 5e (100 MHz) and uses all four pairs. Length within 100 m does not fix the bandwidth limit. Replace the runs with Cat 5e or better for gigabit devices.
10. UTP camera cables are being bundled in a ceiling space used for return air. The crew is using standard nylon cable ties. What does the NEC require?
Answer: Cable ties in plenums must be listed for low smoke and heat release. The NEC requires cable ties and similar accessories in spaces used for environmental air to be listed as having low smoke and heat release properties, the same idea as plenum cable. Plenum-rated cable doesn't excuse ordinary nylon ties. Tighten ties only snugly so the cable jacket isn't deformed.
11. To set up remote viewing, a technician needs the site's public IP address and the name of its ISP. What is the simplest way to find both?
Answer: Visit an IP lookup website from a computer on the site network. Devices on the LAN use private addresses such as 192.168.x.x, so ipconfig or the NVR show only the inside address. An IP lookup website sees the router's public address and reports it with the ISP's name. The public address may change unless the ISP provides a static IP.
12. A new camera cable passes a basic continuity tester, but the camera links only at 100 Mb/s and drops video at gigabit. What is the next step?
Answer: Test with a qualification tester for link quality at speed. A continuity tester proves only the wire map: each pin connected to the right pin. It can't show crosstalk, split pairs or poor terminations that stop a link reaching gigabit. A qualification tester checks whether the cable supports the target speed. T568A and T568B perform the same.
13. A PoE switch has a 370 W power budget and allocates power by class. Each 802.3at Class 4 camera is allocated 30 W. How many cameras can it power?
Answer: 12. 370 W / 30 W = 12.3, so 12 cameras fit; the 13th would exceed the budget even if the switch has more PoE ports. Some switches allocate by actual draw, which can allow more, but plan by class to be safe. Check both the per-port and total budget.
14. A PoE camera must be mounted 150 m of cable away from the nearest PoE switch. What is a standards-based solution?
Answer: Add a PoE extender part way, or run fiber to a media converter. Ethernet over twisted pair, including PoE, is limited to a 100 m channel whatever the cable category. A PoE extender placed within 100 m regenerates the signal and passes power on, or fiber with a powered media converter covers longer distances. More watts don't extend the data reach.
15. An old analog camera run of RG-59 is about 300 m long. The installer plans Ethernet-over-coax adapters that also send PoE. Why measure the cable's DC loop resistance first?
Answer: Its copper-clad steel center conductor may drop too much PoE voltage. PoE current flows through the center conductor and the shield, and many RG-59 cables use a copper-clad steel center conductor with high DC resistance. Over 300 m the voltage drop can leave the camera underpowered. Measure loop resistance and compare it with the adapter's limits. RG-59 is 75 ohm, not 50 ohm.
