NEW QUESTION # 134
Which of the following should a technician consider when adding ten new high-end graphic design and animation desktops at a client site?
- A. The proper ventilation for hazardous fumes
- B. The electrical circuit's power consumption
- C. The local area's temperature
- D. The interior office space's humidity levels
Answer: B
Explanation:
Adding ten high-end graphics/animation desktops can dramatically increase the electrical load on the room's existing circuits. High-performance CPUs and GPUs draw substantially more wattage than typical office PCs, and that wattage translates into higher current (amperage) on the circuit. Mike Meyers' Lab Manual explains the relationship V × A = W and warns that wiring and circuits have amperage ratings; pushing too much current can overheat wiring and trigger safety devices. It also explains that circuit breakers are rated for a specified amperage and will open (trip) when overloaded to prevent overheating and damage. Therefore, before deployment, the technician should calculate expected power draw per system and ensure the desktops are distributed across sufficient circuits (or that electrical upgrades are made) to avoid repeated breaker trips, overheating risks, and downtime. While temperature and humidity matter for environmental control, the question is specifically about introducing multiple power-hungry workstations, making circuit power consumption the most critical planning factor for safe, stable operation. This aligns with A+ operational
/environmental concepts around proper power handling and avoiding overload conditions.

NEW QUESTION # 139
A network administrator notices an unusual spike in traffic directed at the company's primary web server. Upon further investigation, the administrator discovers that the traffic is originating from thousands of different geographical locations and multiple unique IP addresses simultaneously. The volume of requests has overwhelmed the server, making it inaccessible to legitimate users. Which of the following BEST classifies this type of attack?
- A. On-path attack
- B. Structured Query Language injection
- C. Brute-force attack
- D. Distributed Denial of Service
Answer: D
Explanation:
Using many separate systems (endpoints) to attack one target is the defining characteristic of a Distributed Denial of Service (DDoS) attack. Mike Meyers' Lab Manual defines DDoS as: "An attack on a computer or network device in which multiple computers send data and requests to the device in an attempt to overwhelm it so that it cannot perform normal operations." That description exactly matches the scenario: many endpoints are coordinated to flood one endpoint, preventing legitimate use.
This is different from an on-path (man-in-the-middle) attack, which intercepts traffic between two parties; SQL injection, which targets databases via malicious input; and brute-force attacks, which attempt repeated authentication guesses. The key clue is multiple endpoints working together, which implies distribution (often via botnets) and service disruption by volume. That is why the correct classification is Distributed Denial of Service (D).

- D. Subnet mask
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
If internal resources (such as intranet or internal apps) can't be accessed but external sites work, this often points to aDNS issue, where the system isn't resolving internal domain names correctly.
FromAll-in-One Exam Guide:
"When internet access is functional but internal sites fail to load, the issue usually lies with DNS resolution.
Internal resources often require internal DNS servers, which may not be configured correctly."
NEW QUESTION # 141
A technician wants to create new partitions on a device so that a user can keep work data and personal data separate. Which of the following tools should the technician use?
- A. lusrmgr.msc
- B. perfmon.msc
- C. devmgmt.msc
- D. diskmgmt.msc
Answer: D
Explanation:
The correct answer is B. diskmgmt.msc, which opens the Disk Management console in Windows. Disk Management is the primary built-in tool used to create, delete, resize, and format disk partitions.
The Quentin Docter - CompTIA A+ Complete Study Guide explains that disk partitioning is commonly used to separate data for organizational, security, and backup purposes. Disk Management allows technicians to divide a single physical drive into multiple logical volumes, such as one partition for the operating system and another for user data.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide states that diskmgmt.msc provides a graphical interface for managing partitions, drive letters, file systems, and volumes without requiring third- party tools. This makes it the preferred and safest option for partitioning tasks on Windows systems.
The Mike Meyers / Mark Soper Lab Manual clarifies that tools like perfmon.msc monitor performance, lusrmgr.msc manages user accounts, and devmgmt.msc handles hardware devices. None of these tools can modify disk partitions.
Because the task specifically involves creating partitions, Disk Management is the correct and only appropriate tool, making B the correct answer.
NEW QUESTION # 142
A user is attempting to install a high-end 3-D rendering application on a desktop computer. During the installation process, a hardware compatibility check fails, stating that the system does not meet the minimum requirements for the software to run. Which of the following should the technician check FIRST to resolve this issue?
- A. PSU wattage
- B. USB speed
- C. NIC bandwidth
- D. GPU requirements
Answer: D
Explanation:
3-D rendering is a graphics-intensive workload, and minimum hardware checks for this type of software commonly fail due to GPU capability (including dedicated vs. integrated GPU support) and VRAM requirements. Quentin Docter explains that application "Display" requirements can include " a graphics processing unit (GPU). A specific GPU may be required if the application will process video or graphics ." He also notes that " VRAM requirements are typically related to applications that are graphic intensive, such as gaming ," which aligns strongly with 3-D rendering workloads.
Mike Meyers' Lab Manual reinforces that " graphically demanding applications... state specific graphics requirements ," and that CompTIA focuses on " dedicated graphics cards versus integrated ones ," because integrated GPUs are often less capable for demanding graphics tasks. It also reminds that systems with integrated GPUs share RAM with graphics, which can matter when software checks VRAM.
Therefore, the first thing to verify is GPU requirements (B) , not USB/NIC/PSU.
NEW QUESTION # 143
A technician is unable to join a computer to the Windows domain However, the computer can ping the domain controller by IP address. Which of the following is the most likely reason?
- A. The computer is not connected to the network
- B. The firewall configuration is wrong
- C. The DNS settings are incorrect
- D. IPv6 is enabled on the computer
Answer: C
Explanation:
Joining a Windows domain requires proper DNS resolution to locate the domain controller by name. Even though the computer can ping the domain controller by IP address, incorrect DNS settings prevent the system from resolving domain services, causing the domain join to fail.
NEW QUESTION # 144
A technician must install a legacy business application on a new computer. The new computer does not meet the application's requirements. Which of the following steps should the technician take to ensure the application installs and runs correctly?
- A. Increase the swap file size to manage potential memory issues.
- B. Run the installation in safe mode to avoid driver conflicts.
- C. Use an application compatibility toolkit to address any software conflicts.
- D. Use a virtual machine to emulate an older OS.
Answer: D
Explanation:
The correct answer is A. Use a virtual machine to emulate an older OS, because virtualization is the most reliable method for running legacy applications that are incompatible with modern operating systems or hardware. When a new computer does not meet an application's requirements-such as OS version, driver support, or system libraries-the issue is typically software compatibility, not system performance.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, virtualization allows technicians to install an older operating system inside a virtual machine (VM) while still using modern hardware. This approach isolates the legacy application in a controlled environment that exactly matches its original requirements, without compromising the security or stability of the host OS.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that virtual machines are a preferred solution when organizations must maintain access to older business-critical software that cannot be updated. Running installers in Safe Mode or increasing swap space does not resolve OS-level incompatibility issues.
The Mike Meyers / Mark Soper Lab Manual further reinforces that compatibility toolkits can help with minor application issues, but they cannot fully emulate missing OS components or deprecated system calls.
Virtualization provides complete compatibility by recreating the expected environment.
Therefore, using a virtual machine with an older OS is the most effective and exam-correct solution.

- C. Using an external hard drive to upgrade the OS
- D. Copying the ISO file to each workstation and executing
Answer: A
Explanation:
PXE image deployment allows operating system upgrades to be performed over the network without enabling removable storage, maintaining the company's security restrictions while upgrading all workstations efficiently.
NEW QUESTION # 146
Which of the following should a technician consider when adding ten new high-end graphic design and animation desktops at a client site?
- A. The proper ventilation for hazardous fumes
- B. The electrical circuit's power consumption
- C. The local area's temperature
- D. The interior office space's humidity levels
Answer: B
Explanation:
High-end graphic design desktops draw significant power, so the technician must ensure the electrical circuit can support the increased power consumption to prevent overloads and outages.
NEW QUESTION # 147
A technician needs to install Windows 11 on a 4TB SSD. The company requires that the drive be partitioned with at least five primary partitions. Which of the following should the technician use? (Select two).
- A. GPT
- B. XFS
- C. FAT16
- D. MBR
- E. NTFS
- F. APFS
Answer: A,E
Explanation:
The correct answers are C. GPT and E. NTFS. The GUID Partition Table (GPT) partitioning scheme is required because it supports more than four primary partitions and disks larger than 2TB. Since the SSD is
4TB and requires at least five primary partitions, MBR is not suitable.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, MBR is limited to four primary partitions and a maximum disk size of 2TB. GPT removes these limitations and is required for modern systems using UEFI firmware, including Windows 11.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that Windows installations on large disks should use GPT in combination with NTFS, which is the preferred Windows file system due to its support for large files, permissions, encryption, and reliability features.
The Mike Meyers / Mark Soper Lab Manual clarifies that FAT16 cannot support large volumes, XFS is a Linux file system, and APFS is designed for Apple systems. None of these are appropriate for a Windows 11 installation.
Because the requirement involves disk size, partition count, and Windows compatibility, the correct combination is GPT for partitioning and NTFS for the file system, making C and E the correct answers.
NEW QUESTION # 148
A user reports that their internally hosted CRM application splash screen attempts to load, pauses for a few seconds, and then disappears. A technician installs the application software on their computer and is able to recreate the issue. When checking the application logs, the technician sees the following:
Windows could not start the CRM Service on Local Computer 10169. The
service did not start due to a log-on failure.
Which of the following would most likely cause this issue?
- A. The bandwidth available is insufficient to run the application.
- B. The computer does not meet minimum hardware specifications.
- C. The user typed their account password incorrectly.
- D. The LDAP service account used by the service is disabled.
- E. VLAN settings are blocking communication to the hosted application.
Answer: D
Explanation:
The log entry indicates the CRM service cannot start due to a log-on failure, which most commonly occurs when the service account used to run the application (often an LDAP/domain service account) is disabled or has incorrect credentials. This prevents the required background service from starting and causes the application to close immediately.
