QUESTION 138
A technician receives complaints that a network fileshare is slow and now unavailable. The server is powered on and accessible via RDP. What should the technician check next?

RAID array status

Data backup integrity

Network connectivity

Available memory

A fileshare becoming slow over time and then failing completely strongly suggests storage subsystem degradation, often due to a failing RAID array. CompTIA A+ explains that slow file access is an early sign of a degraded array, and eventual unavailability indicates the array may have failed or entered a critical state.
Since the technician can still RDP into the server, the OS is functioning, meaning memory is likely not the issue. Network connectivity is sufficient for remote login. Backup integrity does not affect real-time file availability.
Thus, the next step is to check the RAID array status, which directly controls the server’s storage performance and availability precisely what CompTIA identifies as the primary point of failure in such scenarios.

QUESTION 139
An end user reports that their laptop has a blank screen. A technician observes the keyboard lights are on, and the fan is running. Which of the following should the technician do next?

Check the display ribbon cable.

Contact vendor support

Replace the inverter

Connect to an external monitor

When a laptop powers on but the screen is blank, the quickest way to isolate the problem is to connect to an external monitor. This helps determine if the issue is with the laptop display or with the graphics subsystem.
From CompTIA A+ 220-1101 Official Study Guide, Objective 4.1 – Troubleshoot common hardware problems:
“A blank screen on a laptop with power indicators lit should be tested with an external display first to rule out a faulty screen or ribbon cable.” Verified Source:

QUESTION 140
A systems administrator deploys BitLocker to all devices. However, one of the desktop PCs is not able to encrypt the boot drive. Which of the following should the administrator check?

TPM

CPU

RAM

HDD

BitLocker Drive Encryption in Windows requires aTrusted Platform Module (TPM)to encrypt the boot drive securely. The TPM is a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. It validates system integrity during boot and securely stores the encryption keys. If BitLocker cannot find a TPM or it is disabled in BIOS/UEFI, drive encryption cannot proceed.
BitLocker can function without TPM using a USB startup key, but this compromises some security and is not recommended for managed enterprise environments.

Client virtualization

Software as a service

Sandboxing

Embedded software

Client virtualization involves installing an application on a server and enabling multiple users to run the application simultaneously via virtualized sessions. This eliminates the need for individual installations on local machines.
Why Not B (Software as a Service): SaaS delivers software over the internet and does not require local installations but is managed by a third party, not the organization itself.
Why Not C (Sandboxing): Sandboxing is for isolating applications for security testing, not for concurrent user access.
Why Not D (Embedded software): Embedded software is installed on hardware devices, not shared across multiple users.
