QUESTION 16 Within a single AS, what is meant by hot potato routing? O The round robin pinging of routers within an AS to determine which ones have gateway access. O A situation where a router or SDN controller with two gateway options for a datagram leaving the AS will plan a route to the nearest gateway with respect to costs within the AS and without considering subsequent inter-AS costs. Oscillations in optimal routing that are introduced when optimal routes get saturated with traffic, causing them to become sub-optimal in future routing calculations. O A situation in which inefficiencies in routing causes a datagram to enter a cycle and revisit routers that it already passed through during the same trip. QUESTION 17 At the link layer, what is the purpose of a cyclic redundancy check (CRC)? O To help establish the authenticity of the data in a frame, which helps thwart IP spoofing attacks. O To help determine whether there are any bit errors in a received frame. O To help deduplicate frames that are accidentally received twice (e.g., due to no ACK, collision, or multi-path interference) O To be used as a hash value to associate an ACK response with a successfully received frame. QUESTION 18 In what scenario is TDMA (with 10 time slots per round) a more efficient and fair protocol than ALOHA in a multi-access communication channel? O When there are 9 or 10 stations transmitting simultaneously. O When there are 2 or 3 stations transmitting simultaneously. O Only when there is a single station transmitting When there are significantly more than 10 stations transmitting simultaneously.
