Marketing department users report network performance degradation in the morning and early afternoon, but sales and customer service department users do not report any issues. All structured cabling Is Cat 5e. All departments are connected to a core switch. The running network configuration shows the following:
Which of the following is the most likely cause of the performance issues?
正解：A
解説：
From the configuration, the Sales and Customer Service ports are hard-set to full duplex, 1000 Mbps, while the Marketing interface (GigabitEthernet0/3) is set to duplex auto and speed auto. CompTIA A+ explains that mismatched or lower-negotiated speeds and duplex settings can cause noticeable network slowdowns, collisions, and retransmissions-especially at busy times of the day when utilization is high.
Because all cabling is Cat 5e, it fully supports Gigabit Ethernet, so the cabling is not the limiting factor. The IP addresses are all in the same subnet (192.168.1.0/24) and formatted correctly, so there is no subnet or addressing problem. That rules out options A and C.
With speed auto, the Marketing port may be negotiating only 10/100 Mbps, or even a duplex mismatch (e.g., half duplex vs full). This would severely limit throughput compared to the gigabit links used by the other departments. In peak periods, that slower link would become congested first, which matches the users' reports of performance degradation only in Marketing.
Therefore, the most likely cause is that the Marketing interface is operating at 10/100 instead of 1000 Mbps, making option D correct.

Which of the following protocols is used for sending emails?
正解：D
解説：
SMTP is the standard protocol used to send emails from a client to a mail server or between servers.
質問 # 465
Which of the following allows an internal application to be hosted without managing the underlying OS?
正解：D
解説：
Platform as a Service (PaaS) is designed to host and run applications while the cloud provider manages the underlying infrastructure and operating system. With PaaS, an organization deploys its internal application code (and often configures runtime settings), but does not handle OS installation, patching, hardening, or most server maintenance tasks. This aligns with CompTIA A+ Core 1 cloud concepts that compare service models by responsibility: as you move from IaaS to PaaS to SaaS, the provider manages more of the stack.
IaaS (Infrastructure as a Service) provides virtualized compute, storage, and networking, but the customer still manages the OS, updates, drivers, and the application stack-so it does not meet the "without managing the underlying OS" requirement. SaaS (Software as a Service) delivers a complete finished application to users (like email or CRM), which typically doesn't fit hosting a custom internal application you develop. UCaaS focuses on communication services (voice, video, messaging) rather than general application hosting.
Therefore, PaaS is the best option for hosting an internal application without managing the underlying OS.
質問 # 466
A technician is building a home desktop computer. The technician wants to prioritize cable management when considering the type of power supply. Which of the following power supply types should the technician consider?
正解：A
解説：
A modular power supply is the best choice when cable management is a priority. According to CompTIA Core 1 (220-1201) power supply objectives, modular PSUs allow technicians to connect only the cables that are needed for the system's components, reducing clutter inside the case.
This improves airflow, simplifies troubleshooting, and creates a cleaner internal layout, which is especially beneficial in home-built desktop systems. Semi-modular and fully modular power supplies offer varying degrees of flexibility, but all modular designs reduce unused cables compared to standard power supplies.
A standard (non-modular) power supply has all cables permanently attached, often resulting in excess unused cables that obstruct airflow. A backup power supply refers to an uninterruptible power supply (UPS), which provides battery backup but does not improve internal cable management. A redundant power supply is typically found in enterprise servers and includes multiple PSUs for fault tolerance, not cable management.
CompTIA emphasizes modular power supplies as a best practice for clean builds and efficient system design, making this the correct answer.
質問 # 467
Which of the following networking hardware devices is primarily used to connect different network segments and forward data based on MAC addresses?
正解：D
解説：
A switch operates at Layer 2 and forwards frames between network segments using MAC address tables, enabling efficient communication within a local network.
