TMK1TDC Electrical Cross-Connections Require Intra-Board Configuration
Short answer
A TRUE: configuring electrical cross-connections for a TMK1TDC board requires creating the intra-board cross-connections.
Question
Key Takeaways
It tests board-specific electrical-layer grooming: TMK1TDC uses an intra-board cross-connection, and the trap is assuming every OTN electrical path must pass through a centralized cross-connect board.
This H31-341-V2.5 item tests whether electrical cross-connections on a TMK1TDC board require intra-board provisioning; the correct verdict is TRUE (A).
Common mistake: Answering FALSE because you assume all electrical cross-connections must be routed through an external cross-connect matrix; for TMK1TDC the required configuration is an intra-board cross-connection.
Expert Analysis
Governing rule
The item turns on how NG WDM electrical-layer grooming assigns cross-connection responsibility. When a board contains its own electrical cross-connect matrix, the client-to-line or port-to-port path is provisioned locally as an intra-board cross-connection on that board. The governing principle comes from the electrical-layer grooming and commissioning doctrine for NG WDM equipment: the board's role determines whether the cross-connection is local or centralized.
Applying it to TMK1TDC
TMK1TDC is treated in this question as a board whose electrical cross-connections are made internally. Therefore, when you configure electrical cross-connections for that board, the required action is to create the intra-board cross-connection. You do not treat it as a path that must be routed through a separate cross-connect board. The word “must” is decisive: the statement says intra-board cross-connections are a required configuration step for this board, not merely one possible choice.
Why TRUE
Option A matches that principle. Option B would be correct only if the board had no local cross-connect function and every electrical path had to traverse a centralized matrix, which is not the scenario described. A substantive comment on the item reaches the same conclusion: it identifies the mandatory intra-board cross-connection as the core technical requirement. For exam purposes, remember the board-specific rule: configure the local cross-connection on TMK1TDC rather than assuming an external matrix is always involved.
Exam Strategy
Treat TRUE/FALSE configuration items as board-capability questions first: identify whether the named card owns the cross-connect function or hands traffic to a separate matrix. When the wording contains “must,” test whether the named board makes the step mandatory; a local matrix usually makes an intra-board cross-connection obligatory. Eliminate FALSE only if you can name the external resource that would replace that local step. This habit transfers to OTN grooming and protection questions where board role determines the provisioning path.
