1. 1

   In an authoritative server architecture, which system makes the final decision about the valid game state?

   

   A The client with the lowest latency B The game server C Each client independently
2. 2

   Which delivery method is generally best for frequent player-position updates when an older update becomes useless after a newer one arrives?

   A Unreliable sequenced delivery B Reliable ordered delivery C Reliable delivery with unlimited retries
3. 3

   The diagram shows two received snapshots and a render point deliberately placed between them. Which technique uses this arrangement to produce smooth remote-player movement?

   

   A Packet retransmission B Server sharding C Snapshot interpolation
4. 4

   What is the primary purpose of client-side prediction in a real-time multiplayer game?

   A To remove the need for server validation B To show an immediate local response before the server reply arrives C To guarantee that all clients simulate identical results
5. 5

   A client receives an authoritative position that differs from its predicted position. What is the standard reconciliation procedure?

   

   A Apply the server state, then replay locally stored inputs the server has not processed B Ignore the server state and continue from the predicted position C Delete all input history and freeze until another snapshot arrives
6. 6

   A player fires at an opponent who appeared under the crosshair on the shooter's screen, but the opponent has already moved on the server. Which server technique can evaluate the shot using the relevant historical state?

   

   A Delta compression B Interest management C Lag compensation through server rewind
7. 7

   In a rollback networking model, what happens when a late remote input differs from the input previously predicted for that frame?

   A The late input is always discarded B The game restores an earlier state and resimulates subsequent frames C The entire match restarts from its initial state
8. 8

   What property is essential for deterministic lockstep networking?

   A The same ordered inputs must produce the same simulation result on every peer B Every object's full state must be transmitted each frame C All rendering hardware must be identical
9. 9

   The diagram shows a client receiving updates only for nearby entities inside a defined region. Which optimization does this represent?

   

   A Client-side prediction B Reliable retransmission C Interest management
10. 10

    What does delta compression usually transmit for a replicated game state?

    A A complete copy of every entity in every packet B Only values that changed relative to an agreed baseline C Only player input, never state information
11. 11

    What does a server tick rate of 60 Hz mean?

    A The server advances its simulation approximately 60 times per second B Every client receives exactly 60 complete snapshots per second C The network round-trip time is fixed at 60 milliseconds
12. 12

    In a reliable ordered data stream, what can happen when one packet is lost but later packets arrive successfully?

    A The missing packet is skipped permanently and order is ignored B Later packets are automatically converted into unreliable messages C Delivery of later data may wait until the missing packet is recovered
