The relevant observation is that the planned multimode optic supports too short a reach for the installed path while suitable single-mode optics exist. The support goal is to choose optical media and transceivers matched to distance and wavelength; this diagnose action specifically addresses single-mode versus multimode fiber without confusing a different subsystem.
Incorrect Answers
A:
Inspect motherboard slot shape and part type against service requirements. This action is appropriate for sodimm versus dimm form factor, normally when a desktop repair requires replacement memory but the spare part comes from a notebook. Here the observed facts require single-mode versus multimode fiber instead.
B:
Check the device's Thunderbolt markings, controller support and cable type. This action is appropriate for usb-c versus thunderbolt port capability, normally when an external high-bandwidth storage enclosure only negotiates low speed on a laptop USB-C connector. Here the observed facts require single-mode versus multimode fiber instead.
D:
Read motherboard M.2 keying and SATA or PCIe lane support alongside drive protocol. This action is appropriate for nvme pcie versus sata storage interface, normally when a technician orders an M.2 SSD for a motherboard slot that supports only SATA signaling. Here the observed facts require single-mode versus multimode fiber instead.
Question 231
A support request at Aster Systems presents this problem: A documentation team confuses a smartwatch link with the branch WAN because both are wireless. The desired outcome is to identify network categories from distance and administrative scope. The technician must document observations separately from assumptions. Which verification result supports the intended technical outcome?
- Confirm each segment is classified by scope rather than the brand of equipment
- Verify internet access and signal status follow the approved provider equipment path
- Verify upload and download meet agreed service performance targets
- Verify permitted inter-subnet traffic succeeds and disallowed networks remain isolated
Explanation
Correct Answer
A:
Confirm each segment is classified by scope rather than the brand of equipment. It proves the required function with an observable result instead of assuming the change worked. The relevant observation is that a documentation team confuses a smartwatch link with the branch WAN because both are wireless. The support goal is to identify network categories from distance and administrative scope; this validate action specifically addresses pan versus lan versus wan scope without confusing a different subsystem.
Incorrect Answers
B:
Verify internet access and signal status follow the approved provider equipment path. This action is appropriate for ont versus cable modem access equipment, normally when a customer receives a fiber-to-the-premises service but attempts to connect the optical fiber directly to a DOCSIS cable modem. Here the observed facts require pan versus lan versus wan scope instead.
C:
