A network engineer in his office situated in Beijing China was trying to connect a server in Singapore. He could not connect. Then he tried to connect to a server in his another office branch
in Beijing but also he could not connect to that server. What hardware is causing this problem?
Pinpoint and define that hardware device.

"Ethernet LAN" causing the given issue. A further explanation is given below.

Explanation:

Ethernet technology should be used throughout the LAN design. The LAN infrastructure could be calculated in advance while using a router and perhaps a secure internet link Network switch, as well as your computer can indeed be attached to something like the LAN.  LAN spreads throughout a local community and therefore could be connected to server machines within the same long separation, so limited that this only encompasses the department as well as property around which the LAN was already constructed.

Solution: the categorization of functional and non-functional requirement are as follows: some of the more typical functional requirements include: • business rules• transaction corrections, adjustments and cancellations• administrative functions• authentication• authorization levels• audit tracking• external interfaces• certification requirements• reporting requirements• historical data• legal or regulatory requirementswhile,some typical non-functional requirements are: • performance – for example response time, throughput, utilization, static volumetric• scalability• capacity• availability• reliability• recoverability• maintainability• serviceability• security• regulatory• manageability• environmental• data integrity• usability• interoperability
