JTIDS 102 Quiz 2 UPDATED ACTUAL
Exam Questions and CORRECT Answers
Know the difference between different MIDS variance and which ones have High Power
amplifying groups? - CORRECT ANSWER - MIDS LVT-5
MIDS LVT-8
Be able to differentiate between a frame and a time slot - CORRECT ANSWER - The
frame is the basic recurring unit of time
The time slot is the basic recurring unit of access
Be able to identify which packing structures offer the most throughput and which ones offer the
most anti jam protection - CORRECT ANSWER - Standard Double Pulse is the most jam
resistant
Pack-4 Single pulse offers the most throughput
Know the pulses for each packing structure - CORRECT ANSWER - Standard Double
Pulse - 258
Pack-2 Single Pulse - 258
Pack-2 Double Pulse - 444
Pack-4 Single Pulse - 444
How many pulses are in each transmission? - CORRECT ANSWER - Each pulse contains
five transmission bits
be able to explain the purpose of radio notch filter assembly - CORRECT ANSWER -
IFF/SIF operate in the 1030 to 1090 frequencies and DoD has ensured we do not interfere with
their operations, so thy black transmissions from 1008 to 1053 and from 1065 to 1113
Be able to explain how the pseudo random selection of the 51 center frequencies are established -
CORRECT ANSWER - TSEC crypto
, Know how link margin and range ratio techniques are employed - CORRECT ANSWER -
It is used for anti-jamming to determine where the jammer is located
Be able to identify two IA techniques utilized to protect transmission data - CORRECT
ANSWER - Reed-Solomon
Double Pulse
Know the definition of all the different access modes and techniques - CORRECT
ANSWER - Dedicated Access - One unit is assigned to transmit while others receive
Contention Access - If two units are transmitting in the same time slot, the units will transmit to
whoever is closer to the
TSR - users dynamically share network capacity based on individually estimated demand
Understand how contention access works with the relationship between transmitters and
receivers - CORRECT ANSWER - The receiver will get information from which ever
transmitter is closer
Be able to correctly define the different types of relay - CORRECT ANSWER -
Unconditional Relay - only one unit has the function enabled
Conditional Relay - highest altitude
Flood Relay - any time slot designated for relay is relayed by everyone
Zoom Relay - selected time slots on one net can be relayed onto another net
Multi-hop Relay
Know what is needed for terminals to exchange information over RF Link 16 - CORRECT
ANSWER - LOS, Signal, and Electronic propogation
Know the rules regarding crypto time offset usage - CORRECT ANSWER - A unit cannot
get back into the network until the difference in time between networks has expired
