A technician is experimenting with network configurations and has connected two laptops to an unmanaged switch. The technician configured one of the laptops with a static IP address of 192.168.1.1 and the other with a static IP address of 192.168.2.2. The laptops are not communicating with each other.
Which of the following is the most likely explanation for this issue?
- A . The technician needs to use a hub instead of a switch.
- B . The wireless NICs are malfunctioning.
- C . PoE interferes with intersubnet communication.
- D . The laptops do not have access to a router.
A technician is setting up a new SOHO wireless router.
According to security best practices, which of the following should the technician do first?
- A . Enable encryption.
- B . Assign a static IP.
- C . Change the default password.
- D . Reset the router.
C
Explanation:
The first security step after deploying a new router is to change the default administrative password.
Default credentials are well known and pose a security risk if left unchanged.
From CompTIA A+ 220-1101 Official Study Guide, Objective 2.3 C Secure a wireless network:
“Always change default administrative credentials before further configuration to prevent unauthorized access.”

A user cannot see the office multifunction printer in their laptop’s print options. They have printed to the device in the past successfully. The user’s laptop is connected to the guest wireless network. Other users on both wireless and wired computers can see and print to the printer.
Which of the following will fix the issue?
- A . Power cycle the printer to refresh connectivity.
- B . Reset the closest wireless AP.
- C . Download the printer driver from the manufacturer’s website.
- D . Connect the laptop to the corporate Wi-Fi.
D
Explanation:
If the user is on a guest network and cannot access internal resources like printers, connecting to the corporate Wi-Fi will place the device on the correct subnet to access the printer.
From CompTIA A+ 220-1101 Official Study Guide, Objective 2.2 C Network segmentation:
“Guest networks are isolated from internal resources for security. Connect to the main corporate Wi-Fi to access shared devices.”

Which of the following devices is used to implement ACL polices for an environment?
- A . Managed switch
- B . Gateway
- C . Repeater
- D . Firewall
D
Explanation:
A firewall implements ACLs (Access Control Lists) to filter traffic and enforce policies based on rules such as IP address, port, or protocol.
Why Not A (Managed switch): A managed switch supports VLANs and QoS but does not enforce ACLs at the network perimeter.
Why Not B (Gateway): Gateways connect networks and translate protocols but don’t typically implement ACLs.
Why Not C (Repeater): Repeaters extend signal range but don’t enforce policies.

Reference: Core 1 (220-1201), Section 2.2, firewall concepts.
Which of the following storage options would a technician most likely recommend to have large amounts of affordable capacity without concern for read times on a desktop computer?
- A . 750GB NVMe M.2 SSD
- B . 2x 1TB PCIe SSD in RAID 1
- C . 2TB SATA 3.5" 5,400rpm HDD
- D . 4TB SAS 2.5" 15,000rpm HDD
C
Explanation:
If performance is not a primary concern and the user requires large, cost-effective storage, a2TB 5400rpm SATA HDD is ideal. It offers high capacity at a lower price point than SSDs and faster HDDs.
Option A: NVMe drives offer exceptional speed but are significantly more expensive per GB and not necessary when read/write speed is not a concern.
Option B: RAID 1 improves redundancy but cuts usable capacity in half and uses expensive SSDs.
Option D: SAS drives are fast and reliable but are enterprise-grade and expensive overkill for desktop use.

Reference: Objective 1.3: Given a scenario, install and configure storage devices.
Which of the following is used primarily for archiving data?
- A . PAN
- B . MAN
- C . SAN
- D . LAN
- E . WAN
C
Explanation:
A Storage Area Network (SAN) is primarily used for data archiving and large-scale storage. SANs provide high-speed, block-level storage for enterprise environments.
Why Not A (PAN): Personal Area Networks are for connecting personal devices like phones and smartwatches.
Why Not B (MAN): Metropolitan Area Networks are for city-wide data communication, not storage.
Why Not D (LAN): Local Area Networks are for general connectivity, not dedicated storage.
Why Not WAN: Wide Area Networks are for connecting geographically dispersed networks, not storage.

A user reports intermittent Wi-Fi issues in an open office. Other users are not affected.
What is the most likely cause?
- A . Interference from other Wi-Fi signals
- B . All users are on the same frequency
- C . The laptop’s wireless card is malfunctioning
- D . The antenna is near a device creating electromagnetic interference
C
Explanation:
Since only one user experiences the issue in a shared environment where everyone else has stable connectivity, CompTIA A+ suggests that the problem is most likely with the client device, not the network. The wireless card may be failing, overheating, or experiencing intermittent hardware faults.
If other Wi-Fi signals or EMI (electromagnetic interference) were the cause, multiple users would be affected. Frequency congestion (Option B) also impacts groups, not a single device.
CompTIA stresses that isolating whether the issue affects one user or many helps determine whether the fault lies with the network or device. Because the problem is isolated, the most probable cause is a malfunctioning wireless NIC in the user’s laptop.
