661. Frage
Which of the following has the best penetration through physical objects, such as walls?
Antwort: C
Begründung:
2.4GHz Wi-Fi signals have better penetration through walls and other obstacles compared to 5GHz and
6GHz. Lower frequency waves (like 2.4GHz) travel farther and are less absorbed by physical barriers.
From the CompTIA A+ 220-1101 Official Study Guide, Objective 2.5 - Compare and contrast wireless networking protocols:
"The 2.4GHz frequency band offers greater range and better penetration through walls and obstacles than higher frequencies like 5GHz and 6GHz. Higher frequencies provide faster speeds but are more easily absorbed by walls." NFC (Near Field Communication) is not a Wi-Fi technology and works only over very short distances (a few centimeters).

662. Frage
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?
Antwort: C
Begründung:
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.
663. Frage
A computer displays an error message indicating there is insufficient storage when installing applications. The user reports slow application load times. Which of the following replacement components would best resolve this issue?
Antwort: C
Begründung:
Upgrading to asolid-state drive (SSD)providesmore storage spaceandfaster read/write speeds, which resolves both the "insufficient storage" error and slow application loads.
Option B (USB):Not intended for permanent application storage or performance improvements.
Option C (HDD):Could solve storage capacity but would not improve speed.
Option D (RAM):Affects multitasking and memory-intensive tasks, not storage capacity directly.
CompTIA A+ Core 1 Exam Objective Reference:
Objective 3.5: Given a scenario, troubleshoot problems related to storage devices.

An office manager reports that a printer is experiencing performance issues. Printouts are smudging when they are handled, and, recently, whenever the manager tries to print oversized documents, the paper jams before anything is printed on it.
INSTRUCTIONS
Using the available printer parts, replace only the faulty components on the office printer to resolve the stated issues.
