A QoS policy examines a packet's markings and assigns it to a forwarding class. Which QoS function is being performed?

• A. Policing
• B. Classification
• C. Shaping
• D. Optical amplification

Which of the following statements correctly describes downstream and upstream transmission in a GPON network?

• A. Downstream traffic is broadcast from the OLT toward the ONTs, while upstream transmissions use OLT-controlled time slots.
• B. Downstream traffic uses time slots assigned individually by each ONT, while upstream traffic is broadcast to all ONTs.
• C. Both downstream and upstream traffic are continuously broadcast without coordination by the OLT.
• D. Downstream and upstream traffic require separate optical fibers between the OLT and each ONT.

Which Altiplano intent is used to define the uplink interfaces that connect an OLT toward the aggregation network?

• A. Multicast-report intent
• B. Uplink-connection intent
• C. Subscriber-authentication intent
• D. Wi-Fi-radio intent

A subscriber installs several coordinated Wi-Fi access points to provide consistent coverage throughout a large home. What type of solution is this?

• A. Virtual network function
• B. DSL bonding group
• C. Passive optical network
• D. Wi-Fi mesh system

Which characteristic distinguishes G.fast from traditional ADSL technologies?

• A. G.fast carries only voice services and does not support broadband data.
• B. fast is designed to deliver high broadband rates over relatively short copper loops, frequently using existing building or drop wiring. It uses a much wider and higher-frequency spectrum than traditional ADSL and commonly employs Time Division Duplexing. With TDD, upstream and downstream transmission use the same frequency spectrum during different time intervals. The upstream-to-downstream capacity ratio can therefore be adjusted through the TDD configuration. Higher frequencies can support greater capacity but experience substantial attenuation over distance, which is why G.fast is best suited to short loops. It does not operate through passive optical splitters, although fiber may be deployed close to the subscriber before the final copper segment. G.fast also supports broadband services rather than voice-only delivery.
• C. G.fast operates only over passive optical splitters.
• D. G.fast commonly uses high frequencies and time-division duplexing over short copper loops.
• E. G.fast requires a separate copper pair for upstream and downstream traffic.
