Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Default metric (TLV 2)
Why it's wrong here
Default metric is the original narrow metric.
- ✗
Narrow metrics (TLV 128/130)
Why it's wrong here
Narrow metrics are 6-bit and insufficient for TE.
- ✗
TE metric (TLV 138)
Why it's wrong here
TLV 138 is for TE, but wide metrics are the base.
