Zorluk: ZorNetwork Types and Topologies

A network administrator is evaluating the network infrastructure for a regional health system. The system consists of three distinct communications segments:
1. Medical telemetry sensors communicating with a patient monitoring display positioned 0.5 m0.5\text{ m} away via low-power Bluetooth.
2. High-speed wired Ethernet connecting workstations within a single local clinic building.
3. A dedicated service-provider connection linking the clinic to a remote data center located 45 miles away across state lines.

Which of the following statements correctly classify the network scopes or device requirements for this environment? (Select TWO.)

  1. The short-range Bluetooth communication between the sensors and the monitor display is classified as a Personal Area Network (PAN).Cevap
  2. The dedicated service-provider link spanning 45 miles to the remote data center is classified as a Wide Area Network (WAN).Cevap
  3. C
    The short-range Bluetooth communication between the sensors and the monitor display is classified as a Metropolitan Area Network (MAN).
  4. D
    Interconnecting the clinic's local Ethernet subnets to the distinct IP subnet of the remote data center can be accomplished using an unmanaged Layer 2 switch at each boundary.

Cevap

The short-range Bluetooth link is classified as a Personal Area Network (PAN), and the 45-mile dedicated line to the remote data center is classified as a Wide Area Network (WAN).
Bluetooth communication restricted to short distances (under 10 meters) around localized hardware defines a Personal Area Network (PAN). Furthermore, network connections traversing long geographical distances (such as 45 miles across state lines) via dedicated telecommunications infrastructure represent a Wide Area Network (WAN).

Adım Adım Çözüm

1
Analyze Segment 1 (Sensors to Monitor display via Bluetooth at 0.5 meters)
Identified as a Personal Area Network (PAN) due to its extremely short range (< 10 meters) focused around an individual workstation or device pair.
PANs cover small personal spaces, typically utilizing Bluetooth, NFC, or localized short-range wireless protocols.
2
Analyze Segment 2 (Clinic Ethernet) and Segment 3 (45-mile connection to remote data center)
Segment 2 represents a Local Area Network (LAN), while Segment 3 represents a Wide Area Network (WAN).
WANs span broad geographic distances between distant sites, often across cities or states, utilizing leased ISP infrastructure.
3
Evaluate router vs. switch requirements for inter-subnet communication across the WAN boundary
Layer 3 routers or Layer 3 switches are mandatory to route traffic between disparate subnets across WAN connections.
Layer 2 switches lack IP routing capabilities and cannot forward traffic across distinct network subnets or WAN links.
