300-420 Question 167
Single answerAn enterprise is planning to connect its branch offices across a metropolitan area using Metro Ethernet. The network design team must ensure low latency, high bandwidth, and point-to-point connectivity between sites. Which Metro Ethernet service type should the team choose to meet these requirements?
- A
Ethernet Line Service (E-Line)
- B
Ethernet LAN Service (E-LAN)
- C
Ethernet Tree Service (E-Tree)
- D
Ethernet VPN Service (E-VPN)
Show answer and explanation
Correct answer: A
Explanation
The Ethernet Line Service (E-Line) is the most suitable choice for this enterprise, as it provides dedicated point-to-point connectivity with high bandwidth and low latency. This makes it ideal for scenarios where two sites need reliable and fast communication, such as branch office connections across a metropolitan area.
- A. Correct.
Ethernet Line Service (E-Line) provides point-to-point connectivity, which is ideal for low latency and high bandwidth requirements between two sites. It fits the described scenario.
- B. Incorrect.
Ethernet LAN Service (E-LAN) offers multipoint-to-multipoint connectivity and is better suited for scenarios where multiple sites need to communicate with each other, not just a point-to-point connection.
- C. Incorrect.
Ethernet Tree Service (E-Tree) is designed for point-to-multipoint connectivity, where a central site communicates with multiple branches. It does not fit the point-to-point requirement.
- D. Incorrect.
Ethernet VPN Service (E-VPN) is typically used in scenarios involving more advanced features like multi-tenancy and redundancy; it is not specific to point-to-point connectivity.
