Question 680
A support request at Juniper Tech presents this problem: A new NVMe SSD is absent from firmware and the storage installer. The supporting record states that motherboard documentation shows one M.2 socket is SATA-only while the installed drive requires PCIe lanes. The desired outcome is to identify storage slot signaling incompatibility before declaring the SSD defective. User data and business service continuity must be preserved. What should the technician verify first to establish the problem?
- Inspect UEFI boot entries, disk detection and approved operating system bootloader
- Check cellular toggle, SIM or eSIM provisioning, airplane mode and signal state
- Identify the failed member, array level, replacement size and current backup state
- Check M.2 socket specifications, BIOS PCIe settings, lane sharing and drive keying
Explanation
Correct Answer
D:
Check M.2 socket specifications, BIOS PCIe settings, lane sharing and drive keying. It checks the likely failure boundary before altering working parts or settings. The relevant observation is that motherboard documentation shows one M.2 socket is SATA-only while the installed drive requires PCIe lanes. The support goal is to identify storage slot signaling incompatibility before declaring the SSD defective; this diagnose action specifically addresses nvme ssd not detected after installation without confusing a different subsystem.
Incorrect Answers
A:
Inspect UEFI boot entries, disk detection and approved operating system bootloader. That action is appropriate for uefi boot order after a second drive, normally when a computer reports no bootable operating system after a new secondary drive was added. Here the observed facts require nvme ssd not detected after installation instead.
B:
Check cellular toggle, SIM or eSIM provisioning, airplane mode and signal state. This action is appropriate for mobile data failure due to disabled cellular, normally when a smartphone can browse over Wi-Fi but cannot connect to the internet when leaving the office. Here the observed facts require nvme ssd not detected after installation instead.
C:
Identify the failed member, array level, replacement size and current backup state. That action is appropriate for degraded raid after a failed member, normally when a mirrored NAS reports one disk failed while files remain available. Here the observed facts require nvme ssd not detected after installation instead.
Question 681
During Pioneer Markets's small-office network service desk, the technician encounters this condition: A new PC never receives an IPv4 lease on its office VLAN. The supporting record states that capture shows DHCP discover broadcasts but no offer from an authorized DHCP server. The desired outcome is to identify DHCP IPv4 client and server UDP ports and scope reachability. The customer requires a verified fix rather than a guess based on one symptom. What should the technician recommend as the corrective approach?
- Restore DHCP server or relay reachability rather than assigning random static client addresses
- Allow approved SMB 445 between specified clients and the file server without opening remote desktop
- Permit the authorized DNS transport paths including TCP 53 without opening unrelated services
- Create a scoped DHCP reservation for the printer MAC instead of relying on an exclusion as an assignment
Explanation
Correct Answer
A:
Restore DHCP server or relay reachability rather than assigning random static client addresses. It corrects the documented cause using the compatible technology and support constraints. The relevant observation is that capture shows DHCP discover broadcasts but no offer from an authorized DHCP server. The support goal is to identify DHCP IPv4 client and server UDP ports and scope reachability; this design action specifically addresses dhcp client and server port roles without confusing a different subsystem.
Incorrect Answers
B:
Allow approved SMB 445 between specified clients and the file server without opening remote desktop.
