Municipal planners confuse Metro Ethernet E-Line with E-LAN when choosing a DCI interconnect service. Which mapping is correct at the concept level?
Select an answer to reveal the explanation.
Short Explanation
E-Line is usually a point-to-point wire; E-LAN is a multipoint party line. Map the Metro Ethernet service shape to how many DC sites need to meet, then choose.
Full Explanation
Carrier Metro Ethernet E-Line offerings are typically point-to-point, suiting two-site DCI attachments, while E-LAN offerings provide multipoint connectivity among more than two endpoints. Either may be valid depending on how many halls must interconnect and whether the DC design needs a shared L2 multipoint domain. Concept-level mapping of service type to topology is the skill under test.
