• Question 232:

  A cloud engineer, who is designing a cloud architecture, needs to ensure the solution is able to immediately fail over to another region in case of an outage and also scale up in the event of high utilization.

  Which of the following should the engineer Implement?

  (Select two).

  A. High availability
  B. Elasticity
  C. Cold storage
  D. Machine learning
  E. Metered utilization
  F. Virtualization
  A. High availability
  B. Elasticity

  ---

  Explanation

  The answer is

  A. High availability and

  B. Elasticity.

  High availability is the ability of a system to remain operational and accessible with minimal or no downtime, even in the event of failures, disasters, or disruptions. High availability can be achieved by designing a system that has redundancy, fault tolerance, and disaster recovery capabilities. For example, a cloud engineer can design a system that replicates data and resources across multiple regions, zones, or availability domains, and uses load balancing and failover mechanisms to distribute the workload and handle failures gracefully 12. Elasticity is the ability of a system to scale up or down automatically in response to changes in demand or utilization. Elasticity can be achieved by designing a system that can dynamically allocate and deallocate resources based on predefined metrics, policies, or triggers. For example, a cloud engineer can design a system that uses auto-scaling groups, horizontal or vertical scaling strategies, and on-demand or spot instances to optimize the performance and cost of the system 32. By implementing high availability and elasticity, a cloud engineer can ensure that the solution is able to immediately fail over to another region in case of an outage and also scale up in the event of high utilization. These are two important aspects of building reliable and scalable cloud architectures. Therefore, options A and B are the correct answers.

• Question 233:

  A technician plans to upgrade a laptop's RAM from 4GB to 16GB.

  Which of the following should the technician do?

  A. Purchase the same architecture of RAM.
  B. Configure the laptop's BIOS settings for the RAM upgrade.
  C. Purchase RAM with the same CAS latency.
  D. Purchase the same brand of RAM.
  A. Purchase the same architecture of RAM.

  ---

  Explanation

  The most important factor to consider when upgrading a laptop's RAM is the architecture of the RAM, which determines the type, speed, and capacity of the memory modules. The architecture of the RAM must match the architecture of the laptop's motherboard and processor, otherwise the RAM will not be compatible or function properly. The architecture of the RAM includes the DDR generation (such as DDR3 or DDR4), the form factor (such as SO-DIMM), the pin count (such as 204 or 260), the voltage (such as 1.35V or 1.5V), and the frequency (such as 1600MHz or 2400MHz). The other options are not as crucial or relevant for the RAM upgrade. The brand of the RAM does not matter as long as the RAM meets the specifications of the laptop and is of good quality. The CAS latency of the RAM is a measure of the delay between the memory controller requesting data and the RAM delivering it, and it affects the performance of the RAM. However, the CAS latency is not a fixed value and can vary depending on the frequency and voltage of the RAM. Therefore, purchasing RAM with the same CAS latency is not necessary or sufficient for compatibility. The laptop's BIOS settings are usually configured to automatically detect and adjust to the RAM upgrade, and do not need to be manually changed by the technician.

• Question 234:

  A consultant is assessing the wireless configurations for a small office. The existing equipment uses WEP encryption and operates on the default channel. The office is in a crowded urban area with many nearby networks.

  Which of the following is the best way to improve the wireless network performance?

  A. Replacing the access point
  B. Disabling SSID broadcasting
  C. Enabling MAC address filtering
  D. Updating the firmware
  A. Replacing the access point

  ---

  Explanation

  Comprehensive and Detailed Explanation

  The wireless environment is crowded , and the office is using:

  WEP encryption # obsolete, insecure, and supported only by outdated hardware

  Default channel # likely causes interference in a busy area

  CompTIA A+ emphasizes:

  WEP should be replaced with WPA2 or WPA3

  Older APs that only support WEP cannot simply be updated

  Newer APs also allow dual-band / multiple channels to avoid interference

  Therefore, the best solution is:

  # Replace the access point with a modern WPA2/WPA3-capable AP that supports improved channel selection.

  Why the other options are incorrect

  B. Disabling SSID broadcast -Does nothing for performance or security.

  C. MAC filtering -Ineffective for performance and easily bypassed.

  D. Updating firmware -Cannot upgrade WEP hardware to WPA2/3 if hardware limitations exist. Final Answer: A

• Question 235:

  A small company recently added VoIP through its ISP. Users report intermittent call quality issues during peak hours.

  Which of the following steps should the IT administrator take to solve the issue?

  A. Configure the VLAN to split services.
  B. Route calls through a gigabit port.
  C. Install a shielded network cable.
  D. Increase the VoIP bit rate.
  A. Configure the VLAN to split services.

  ---

  Explanation

  Comprehensive and Detailed Explanation CompTIA A+ VoIP and network performance topics stress the importance of Quality of Service (QoS) and traffic separation.

  Creating a separate VLAN for VoIP:

  Reduces congestion

  Prioritizes voice traffic

  Prevents voice packets from competing with data traffic

  Improves latency, jitter, and packet loss issues during peak hours

  This directly fixes intermittent VoIP quality issues.

  Why the other options are incorrect

  B. Route calls through a gigabit port -Internal port speed is not the bottleneck; congestion is.

  C. Shielded cable -Does not solve bandwidth or QoS issues.

  D. Increase bit rate -Makes the problem worse , requiring more bandwidth.

• Question 236:

  Which of the following is the MAXIMUM power PoE+ provides?

  A. 15.4W
  B. 30W
  C. 60W
  D. 95W
  B. 30W

  ---

  Explanation

  The earliest PoE switches from a few years ago generated 15 Watts per port (IEEE 802.3af). Today, most use the PoE+ standard (IEEE 802.3at), which generates up to 30 Watts per port. That's plenty for most devices that people want to connect

• Question 237:

  An employee requires a workstation with three high-end graphics cards to render 3-D models. A technician must choose a power supply that meets the power requirements for the components and takes into consideration the mission-critical nature of the work.

  Which of the following meet the requirements?

  (Select two).

  A. 12V output
  B. Modularity
  C. 20-pin motherboard connector
  D. Redundancy
  E. 3.3V output
  F. 240 VAC input
  B. Modularity
  D. Redundancy

  ---

  Explanation

  A workstation running three high-end GPUs requires a power supply capable of both high wattage and stable, reliable output. In CompTIA A+ power supply fundamentals, modularity and redundancy are emphasized for high-performance and mission-critical systems.

  Modularity (B) allows the technician to connect only the necessary cables, reducing clutter, improving airflow, and enabling proper cable routing to multiple GPUs. High-end graphics cards require multiple PCIe connectors, and modular PSUs provide the flexibility to attach the exact number of required GPU power cables. This is important for systems where space management and cooling efficiency directly affect performance and component longevity.

  Redundancy (D) is critical for mission-critical workstations used for 3-D modeling and rendering. A redundant power supply ensures that if one PSU module fails, the system continues running without interruption. CompTIA A+ highlights redundancy as a key feature in professional environments where uptime is essential. These systems typically use dual hot-swappable power modules to guarantee continuous power delivery.

  The other options do not meaningfully address the requirements. A 12V output is standard on all PSUs. A 20- pin connector is outdated; modern motherboards use 24-pin. The 3.3V rail is not relevant to GPU loads, and 240 VAC input only refers to wall power compatibility, not PSU capability. Therefore, modularity and redundancy best meet the workstation's needs.

• Question 238:

  A technician wants to upgrade a computer to a new Windows version. The Windows Upgrade Advisor states that the computer is not compatible with the new Windows version due to a lack of TPM 2.0 support.

  Which of the following should the technician do next?

  A. Enable the module in the UEFI BIOS.
  B. Install an HSM in the computer.
  C. Perform a clean Install of the new Windows version.
  D. Implement BitLocker on the computer.
  A. Enable the module in the UEFI BIOS.

  ---

  Explanation

  TPM 2.0 (Trusted Platform Module) is often disabled by default in the UEFI BIOS. Enabling it is necessary to meet the requirements for certain Windows installations, including Windows 11.

  Why Not B (Install an HSM): A Hardware Security Module (HSM) is a separate device used for cryptographic functions and is not related to TPM on the motherboard.

  Why Not C (Perform a clean install): A clean installation will not bypass the TPM 2.0 requirement.

  Why Not D (Implement BitLocker): BitLocker requires TPM but does not resolve its absence or lack of activation.

• Question 239:

  After a laptop display panel was replaced recently, the laptop has had difficulty staying connected to Wi-Fi.

  Which of the following is most likely causing the issue?

  A. The internal antenna has been damaged
  B. Airplane mode is enabled
  C. The inverter is not connected
  D. The wireless drivers have not been updated
  A. The internal antenna has been damaged

  ---

  Explanation

  The correct answer is A. The internal antenna has been damaged.

  According to the CompTIA A+ Core 1 220-1201 objectives under Mobile Devices and Networking:

  Many laptop Wi-Fi antennas are embedded in the display panel and connected via small cables to the wireless card on the motherboard.

  If the display panel is replaced and the Wi-Fi antenna is disconnected, damaged, or improperly routed, the laptop will experience weak or intermittent Wi-Fi connectivity.

  Why the other options are incorrect:

  B. Airplane mode is enabled: Would completely disable wireless radios; the question specifies difficulty staying connected, not a total lack of connectivity.

  C. The inverter is not connected: The inverter powers the backlight of the display, unrelated to wireless connectivity.

  D. The wireless drivers have not been updated: While outdated drivers can cause connectivity issues, a sudden problem after a display replacement strongly points to physical antenna damage.

• Question 240:

  Which of the following is considered a connectionless protocol?

  A. SSH
  B. TCP
  C. HTTPS
  D. UDP
  D. UDP

  ---

  Explanation

  The correct answer is D. UDP.

  UDP (User Datagram Protocol) is a connectionless protocol that does not establish a connection before sending or receiving data. UDP simply sends datagrams to the destination without checking if the receiver is ready or not. UDP does not guarantee reliable delivery, error correction, or in-order arrival of the data. UDP is faster and more efficient than connection-oriented protocols for applications that do not require reliability, such as streaming audio or video1

  A. SSH (Secure Shell) is not a correct answer. SSH is a connection-oriented protocol that uses TCP (Transmission Control Protocol) as its transport layer. SSH establishes a secure and encrypted connection between two network endpoints before exchanging data. SSH provides authentication, confidentiality, and integrity for remote login and command execution2

  B. TCP (Transmission Control Protocol) is not a correct answer. TCP is a connection-oriented protocol that establishes a connection before sending or receiving data. TCP ensures reliable delivery, error correction, and in-order arrival of the data. TCP is slower and more complex than connectionless protocols, but it provides more reliability and quality of service for applications that require it, such as web browsing or email1

  C. HTTPS (Hypertext Transfer Protocol Secure) is not a correct answer. HTTPS is a connection-oriented protocol that uses TCP as its transport layer and SSL/ TLS as its security layer. HTTPS establishes a secure and encrypted connection between a web browser and a web server before exchanging data. HTTPS provides authentication, confidentiality, and integrity for web transactions, such as online banking or shopping1
