Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
E-Line
Why this is correct
E-Line is point-to-point.
- ✗
E-LAN
Why it's wrong here
E-LAN is multipoint.
- ✗
E-Tree
Why it's wrong here
E-Tree is root-to-leaf.
- ✗
E-Access
Why it's wrong here
E-Access defines a UNI-to-NNI (network-to-network interface) relationship for accessing a service provider’s network, not a direct UNI-to-UNI Ethernet connection. It is tempting because it involves Ethernet access, but the stem specifically requires a point-to-point Ethernet service between two UNIs, which is the domain of E-Line. E-Access would be correct if the question asked about linking a customer site to a provider’s aggregation network rather than connecting two customer endpoints.
