Question 340
A support request at Westbrook Energy presents this problem: A two-disk mirror still serves files but its management page shows a failed member and no redundancy. The desired outcome is to restore RAID redundancy without wiping the surviving volume. User data and business service continuity must be preserved. What should the technician verify first to establish the problem?
- Identify the failed member, array level, replacement size and current backup state
- Inspect UEFI boot entries, disk detection and approved operating system bootloader
- Inspect whether the media is direct thermal, coated side, sensor placement and heating element cleanliness
- Check M.2 socket specifications, BIOS PCIe settings, lane sharing and drive keying
Explanation
Correct Answer
A:
Identify the failed member, array level, replacement size and current backup state. It checks the likely failure boundary before altering working parts or settings. The relevant observation is that a two-disk mirror still serves files but its management page shows a failed member and no redundancy. The support goal is to restore RAID redundancy without wiping the surviving volume; this diagnose action specifically addresses degraded raid after a failed member without confusing a different subsystem.
Incorrect Answers
B:
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 degraded raid after a failed member instead.
C:
Inspect whether the media is direct thermal, coated side, sensor placement and heating element cleanliness. This action is appropriate for thermal printer paper orientation, normally when a shipping label printer feeds paper but produces completely blank labels. Here the observed facts require degraded raid after a failed member instead.
D:
Check M.2 socket specifications, BIOS PCIe settings, lane sharing and drive keying. That action is appropriate for nvme ssd not detected after installation, normally when a new NVMe SSD is absent from firmware and the storage installer. Here the observed facts require degraded raid after a failed member instead.
Question 341
During Crescent Operations's end-user troubleshooting, the technician encounters this condition: A laptop can ping 8.8.8.8 but cannot open a business website by its domain name. The desired outcome is to troubleshoot name resolution separately from basic routed network access. Any configuration change must be reversible and validated on a controlled test device. What should support monitor to catch a recurrence of the same failure?
- Monitor DHCP request timeouts and APIPA occurrences
- Monitor resolver errors and DHCP option drift
- Monitor port configuration drift and unexpected subnet allocations
- Monitor CRC errors and recurring physical link events
Explanation
Correct Answer
B:
Monitor resolver errors and DHCP option drift. It tracks recurrence of the specific failure mechanism over time. The relevant observation is that a laptop can ping 8.8.8.8 but cannot open a business website by its domain name. The support goal is to troubleshoot name resolution separately from basic routed network access; this monitor action specifically addresses dns failure with working ip connectivity without confusing a different subsystem.

Question 342
A support request at Granite Capital presents this problem: A two-drive NAS needs continued access after one drive fails rather than the combined capacity of RAID 0. The desired outcome is to choose RAID 1 when simple mirroring is the requirement. A safe non-destructive test must be used before replacing additional parts. Which safe pilot action gives the most relevant evidence?
- Simulate a single disk failure in an isolated RAID 1 test array
- Create a small lab array of two mirrored pairs striped together
- Model two drive failures on a disposable RAID 6 lab array

The support goal is to choose RAID 1 when simple mirroring is the requirement; this pilot action specifically addresses raid 1 mirror capacity and resilience without confusing a different subsystem.
Incorrect Answers
B:
Create a small lab array of two mirrored pairs striped together. This action is appropriate for raid 10 mirrored striped array, normally when a database server needs fast disk I/O and redundancy with four equal drives. Here the observed facts require raid 1 mirror capacity and resilience instead.

Question 343
At Vertex Media, a technician working in branch networking support identifies this issue: A school has long corridors needing range and crowded labs requiring high-capacity wireless access. The desired outcome is to choose bands according to range and interference rather than assuming one is always superior. The technician must document observations separately from assumptions. What should the technician verify first to establish the problem?
- Check adapter specifications, OS support, channel regulations and required security configuration
- Survey RSSI, interference sources, client capabilities and required throughput on both bands
- Map connected endpoints, geography and link boundaries for each example
- Inspect reader specifications, expected distance and supported mobile radio interface

Question 346
During Beacon Group's desktop hardware service bench, the technician encounters this condition: Confidential reports regularly sit unclaimed in a shared hallway printer's output tray. The supporting record states that the multifunction printer supports badge-based secure job release. The desired outcome is to protect printed documents at a shared device. User data and business service continuity must be preserved. Which controlled service test best evaluates the planned approach?
- Print a controlled two-page sample from the target application
- Set a test monitor first to its native resolution then to an available supported refresh rate

Question 347
A support request at Riverlight Retail presents this problem: A networked printer must keep the same IPv4 address while the rest of the office remains DHCP-managed. The supporting record states that a reservation can bind the printer's MAC to one address, while an exclusion only keeps a range from dynamic allocation. The desired outcome is to select a stable printer address assignment without disabling office DHCP. Only approved service procedures and compatible replacement components may be used. Which planned change most directly resolves the documented issue?
- Create a scoped DHCP reservation for the printer MAC instead of relying on an exclusion as an assignment
- Create a separate guest VLAN with appropriate ACLs and a supported authenticated VPN for remote staff
- Correct MX routing to the active mail service without treating SPF as an incoming delivery address
- Configure an approved reachable NTP source for network devices while retaining centralized syslog
Explanation
Correct Answer
A:
Create a scoped DHCP reservation for the printer MAC instead of relying on an exclusion as an assignment. It corrects the documented cause using the compatible technology and support constraints. The relevant observation is that a reservation can bind the printer's MAC to one address, while an exclusion only keeps a range from dynamic allocation. The support goal is to select a stable printer address assignment without disabling office DHCP; this design action specifically addresses dhcp reservation versus exclusion without confusing a different subsystem.

This action is appropriate for mx and spf dns records distinct purposes, normally when a domain receives email at the wrong destination after DNS changes. Here the observed facts require dhcp reservation versus exclusion instead.
D:
Configure an approved reachable NTP source for network devices while retaining centralized syslog. This action is appropriate for ntp time service versus centralized syslog, normally when authentication logs from two branch routers show conflicting timestamps during the same event.
