A student configures a wireless SOHO network to connect four laptops and one multifunction printer.

Comprehensive and Detailed Explanation (100–150+ Words):

CompTIA A+ stresses that printers must use static IP addresses to remain consistently reachable on a LAN. When using DHCP, the printer ' s IP address may change, causing laptops to lose access. By assigning a static IP within the same subnet, the printer becomes a stable, discoverable network resource for all laptops.

Using dynamic IPs for the laptops is perfectly acceptable in SOHO environments, because clients don’t require permanent IPs. Assigning public IPs (Option B) is incorrect and unsafe. APIPA (169.254.x.x) does not route and cannot reach the internet or a standard printer. Using dynamic ISP-assigned IPs for all devices (Option D) is also incorrect because ISP routers typically give only one public IP, not multiple internal ones.

Therefore, to ensure the printer is always reachable, the correct configuration is: DHCP for laptops, static IP for printer a best practice detailed in CompTIA’s networking and SOHO setup guidelines.
