How to pass the SCTE BCSS exam

  • Bring a subnet table: prefix, mask, block size and usable hosts from /24 to /30. Static IP block questions are quick marks if you do not have to work them out from scratch.
  • Know the 90 m (295 ft) permanent link and 100 m (328 ft) channel limits of TIA-568, and which category supports 10 Gbps at full length (Cat 6A).
  • For voice, separate signalling (SIP) from media (RTP). Calls that connect with one-way or no audio point to NAT, firewall or QoS, not to SIP registration.
  • Think like the technician on site: prove the WAN service at the demarcation point before you touch the customer's LAN, and explain findings in plain business terms.

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 law firm needs a guaranteed symmetrical 1 Gbps connection with a service level agreement. The building is served by DOCSIS 3.1 HFC and a fiber lateral passes the property. Which service best meets the requirement?
Answer: A dedicated fiber Ethernet circuit. Dedicated fiber Ethernet gives symmetrical bandwidth on a circuit that is not shared with other subscribers, so an SLA on throughput, latency and availability is practical. DOCSIS 3.1 upstream is far smaller than downstream in typical splits and is shared across the node. Bonding older modems adds cost without guaranteeing symmetry.
2. A business is served from a node that has been converted to Remote PHY. Which function now takes place in the node rather than in the hub?
Answer: Modulation and demodulation of the DOCSIS RF signals. Remote PHY moves the physical layer (QAM and OFDM modulation and demodulation) into the Remote PHY device in the node, while the CCAP core in the hub keeps the MAC and upper layers. The fiber to the node then carries digital Ethernet. Remote MACPHY, a different option, would move MAC scheduling as well.
3. A new office workstation is about 400 ft of cable path from the telecommunications room. The customer wants Cat 6 to a wall jack. What is the correct approach under TIA-568?
Answer: Add a closer telecommunications space so the run is 90 m or less. TIA-568 limits horizontal permanent links to 90 m (295 ft), with up to 10 m of cords for a 100 m (328 ft) channel, for every copper category. Cat 6A does not raise the distance; it raises the bandwidth at that distance. A closer telecommunications room or an intermediate switch keeps every run within the limit.
4. A cable certifier's wire map on a new four-pair run shows pins 1 and 2 at one end connected to pins 3 and 6 at the other, and pins 3 and 6 connected to 1 and 2. What is the most likely cause?
Answer: One end terminated T568A and the other T568B. T568A and T568B differ only by swapping the orange and green pairs, which sit on pins 1-2 and 3-6. Mixing schemes on one link produces exactly this crossed pattern. A split pair passes a simple continuity test but fails crosstalk, and length or shorts show as different faults.
5. A business LAN is divided using the subnet 192.168.10.0/26. How many usable host addresses does each /26 subnet provide?
Answer: 62. A /26 leaves 6 host bits, giving 2^6 = 64 addresses per block. Subtract the network and broadcast addresses to get 62 usable hosts. 126 is a /25 and 30 is a /27, the usual off-by-one-prefix errors.
6. A business is assigned the static block 203.0.113.8/29, and the provider's gateway uses 203.0.113.9. How many addresses are left for the customer's own devices?
Answer: 5. A /29 has 8 addresses: .8 is the network and .15 the broadcast, leaving .9 to .14, which is 6 usable. The provider's gateway takes .9, so 5 remain for the customer's firewall, servers and other devices. Forgetting the gateway gives 6; forgetting network and broadcast gives 8.
7. A PC is set to 10.1.1.70 with mask 255.255.255.192 and default gateway 10.1.1.1. It can reach a printer at 10.1.1.100 but not the internet. What is the problem?
Answer: The gateway address is outside the PC's subnet. A /26 mask (255.255.255.192) makes blocks of 64, so 10.1.1.70 sits in 10.1.1.64 to 10.1.1.127. The gateway at 10.1.1.1 is in a different subnet, so the PC cannot send off-net traffic to it, while the printer at .100 is local. A DNS fault would still allow pings to IP addresses.
8. A restaurant wants guest Wi-Fi and its card-payment terminals on the same switch, but guests must never reach the payment devices. What should you configure?
Answer: Separate VLANs for guest and payment traffic. 802.1Q VLANs create separate layer 2 networks on one physical switch, and traffic between them passes only through a router or firewall that can block it. A second SSID on the same VLAN still shares one broadcast domain. Isolating card-payment devices also supports PCI DSS requirements.
9. A customer with two offices wants a dedicated point-to-point Ethernet link that carries all of its VLANs transparently, with no other services sharing either port. Which MEF service type fits?
Answer: Ethernet Private Line (EPL). EPL is a port-based point-to-point service: one EVC per UNI, so all customer VLANs pass transparently. EVPL is VLAN-based, letting several EVCs share a port. EP-LAN connects three or more sites, and Tree services give a hub-and-spoke (root and leaf) layout.
10. After cutover to a new SIP trunk, outbound calls ring and connect, but the far end cannot hear the office staff. What is the most likely cause?
Answer: NAT or firewall rules blocking the RTP audio stream. SIP signalling set the call up successfully, so registration, DNS and codec negotiation worked. One-way audio comes from the RTP media path, usually a firewall or NAT that does not open or translate the media ports (for example a SIP ALG problem or a wrong external address). Check the firewall's SIP and RTP handling first.
11. An office needs 12 simultaneous calls using G.711 with 20 ms packetization over Ethernet. Roughly how much bandwidth should you plan in each direction?
Answer: About 1.05 Mbps. G.711 is 64 kbps of voice, but RTP, UDP, IP and Ethernet headers on 50 packets a second raise it to about 87 kbps per call per direction. 12 × 87 kbps is about 1.05 Mbps. 0.77 Mbps counts only the codec payload, and 2.09 Mbps adds both directions together.
12. Hotel guests report that they can see other guests' laptops and shared folders on the hotel Wi-Fi. Which setting fixes this?
Answer: Turn on client isolation on the guest network. Client (peer-to-peer) isolation stops wireless clients on the same SSID from sending traffic to each other, so they can reach only the gateway and internet. Power, band or subnet size do not stop devices on the same network from discovering each other. It is standard practice on hospitality and public Wi-Fi.
13. In a hotel, guests lose their session and must log in to the captive portal again each time they move between floors. Each floor's access points are on a different subnet. What is the best fix?
Answer: Put all guest access points on one guest VLAN and subnet. Moving to an access point on another subnet forces a new IP address, which breaks sessions and looks like a new device to the captive portal. Placing all guest APs on one VLAN and subnet (usually via a controller or cloud management) lets clients keep their address while roaming. Separate SSIDs make roaming worse.
14. A new Wi-Fi 6 access point needs 25.5 W at the device. The business's switch supports only IEEE 802.3af PoE. What is required?
Answer: An 802.3at (PoE+) or higher port or injector. 802.3af supplies 15.4 W at the switch and guarantees about 12.95 W at the device. 802.3at (PoE+) supplies 30 W, guaranteeing 25.5 W at the device, and 802.3bt goes higher. A shorter cable reduces loss slightly but cannot raise the class limit.
15. A business reports internet drops that happen mainly during rain. The cable modem's event log shows repeated T3 timeouts. What should the technician do first?
Answer: Check the drop and connectors for upstream ingress. A T3 timeout means the modem sent a ranging request and the CMTS did not answer, which points to upstream signal problems. Drops tied to rain suggest water in connectors or damaged drop cable letting in noise. Fix the RF path before touching the customer's LAN, firewall or Wi-Fi, and escalate to maintenance if the fault is beyond the tap.
