INTRODUCTION TO JOINT MULTI-TDL
NETWORK (MTN) OPERATIONS JT101
(POST TEST 2)
1) Which type of relay requires only that at least one platform be assigned relay
timeslots and has enabled the relay function? - Correct Answers -Unconditional Relay
2) Which of the following are advantages of Indirect (Relay) connectivity? Select all that
apply. [Remediation Accessed :N] - Correct Answers -Extends the connectivity beyond
LOS
(Selected) Increases overall anti-jam strength through increased signal level at the
receiver
(Selected) Provides a robust connectivity through multiple paths
(Selected) Multiplies the time slot requirements (the relayed message needs a time slot
to be transmitted in)

Wrong
5) Which JTIDS/MIDS access mode allows only one unit to transmit per timeslot and
goes unused if that specific participant has no data to transmit? - Correct Answers -
Dedicated access
17) Which of the following IS NOT directed in CJCSI 6232.01 Link 16 Spectrum
Deconfliction? [Remediation Accessed :N] - Correct Answers -NOT Requires terminal
restrictions and transmission deconfliction procedures

Answers -Combat Protect (2)
6) Which JTIDS/MIDS access mode allows multiple participants to share common
timeslots using the same net resulting in receivers hearing the closest transmitter? -
Correct Answers -Contention access
7) Which JTIDS/MIDS access mode allows units to automatically and dynamically
assign surveillance capacity based on platform need? - Correct Answers -Timeslot
Reallocation (TSR)
8) Which JTIDS/MIDS access technique requires the assignment of a net number of 1 -
126 in the OPTASK LINK but is identified as the specific access mode in the Network
Description Document (NDD) as net 127? - Correct Answers -Stacked Nets
9) Which JTIDS/MIDS access technique is not operator selectable and allows different
groups of users to exchange information in different Network Participation Groups
(NPGs)? - Correct Answers -Multi-nets
10) Which JTIDS/MIDS access technique gives two or more platforms the same time
slot, net, and TSEC crypto in which to transmit because they have no requirement to
exchange information? - Correct Answers -Dedicated Timeslot Reuse
11) Which of the following is determined by the Message Security (MSEC) variable in
Link 16? - Correct Answers -Encryption and decryption of message data
12) In which Link 16 security mode are discrete Crypto Variable Logic Labels (CVLLs)
assigned to both TSEC and MSEC? - Correct Answers -Partition Variable Mode (PVM)
13) What numbers are used by a network designer as Crypto Variable Logic Labels
(CVLLs)? - Correct Answers -1 - 127
14) Which are NOT methods that can be used to deconflict Link 16 networks? Select all
that apply. [Remediation Accessed :N] - Correct Answers -Using unique TSEC crypto
keys for the main net
Using different Initialization Data Load (IDL) files
Sufficient Geographic separation
Employing a network time offset
Wrong
