NEW QUESTION # 32
A user is attempting to open on a mobile phone a HD video that is hosted on a popular media streaming website. The user is receiving connection timeout errors. The mobile reception icon area is showing two bars next to 3G. Which of the following is the most likely cause of the issue?
- A. The bandwidth is not fast enough.
- B. The mobile device storage is full.
- C. The user does not have Wi-Fi enabled.
- D. The website ' s subscription has run out.
Answer: A
Explanation:
3G networks generally do not provide the bandwidth required for seamless HD video streaming. With only two signal bars and a 3G connection, the mobile device likely cannot maintain the necessary data throughput, resulting in timeouts or buffering failures. This is a classic symptom of insufficient network speed or signal strength.
A). Lack of Wi-Fi may contribute, but the root cause is the low mobile bandwidth, not the Wi-Fi state.
B). A website subscription lapse would return an account error, not a timeout.
D). Full device storage can affect downloads but not streaming from the internet.

Wireless AP LAN
Firewall Screened Subnet
Answer:
Explanation:
See explanation below.
Explanation:
The completed configuration:
1. Wireless AP (LAN side)
1. LAN IP: 192.168.10.1
2. Encryption: WPA2 PSK
2. Router (port-forward rule)
1. Allow TCP Any 3389
This forwards inbound RDP traffic (TCP/3389) from the Internet to the Windows PC, enabling Remote Desktop access.
3. Firewall (screened subnet side)
1. LAN IP: 10.100.0.1
4. Device placement
1. PC: place behind the router (where the port-forward rule points).
2. Game console: place on the Wireless AP (so it can use chat and extra services over WPA2 PSK).
3. Firewall: place in front of the screened subnet (with its 10.100.0.1 IP facing that subnet).
* The Windows PC is placed in the screened subnet (behind the firewall) for enhanced security. Remote access to this PC requires port forwarding of TCP port 3389 (RDP), which is correctly configured through the router.
* The Game Console is placed on the Wireless AP LAN, using WPA2 PSK for a secure wireless connection. Game consoles typically use peer-to-peer chat and online services that require open access without firewall restrictions, which is why the console is not placed behind the firewall.
CompTIA A+ 220-1102 Reference Points:
* Objective 3.4: Given a scenario, implement best practices associated with data and device security.
* Objective 2.4: Given a scenario, use appropriate tools to support and configure network settings.
* Study Guide Reference: CompTIA A+ Core 2 guides recommend using screened subnets (a type of DMZ) for systems needing controlled external access, such as remote desktops, while placing gaming and media devices on less restricted networks for full functionality.

A technician is 3-D printing high-strength, carbon fiber-based filament parts for a customer order. Which of the following is the most important for the technician to use?
- A. Air filter mask
- B. Steel-toed boots
- C. ESD mat
- D. Antistatic bags
Answer: A
Explanation:
Carbon fiber filamentcan producefine particles or fumesduring printing, which may be harmful when inhaled.
Wearing anair filter maskis essential to protect the respiratory system.
FromQuentin Docter - CompTIA A+ Complete Study Guide:
"When working with advanced materials like carbon fiber, always use appropriate personal protective equipment such as air filter masks to prevent inhalation of dangerous particles."
NEW QUESTION # 39
Which of the following commands can a technician use to view the contents of a single file on a Linux terminal?
- A. chmod
- B. ls (corrected from "Is")
- C. sudo
- D. cat
Answer: D
Explanation:
To display a file's contents in Linux, the standard command is cat. Quentin Docter states: "Sometime you just need to view the contents of a file. To view the contents of a file, use the cat command," and shows an example cat /etc/hosts displaying the file output. He also lists essential Linux commands and explicitly defines cat as: "Displays the contents of a file." The other options do not meet the requirement: chmod changes file permissions, ls lists directory contents (or file names), and sudo runs a command with elevated privileges-none directly display a file's contents by themselves. A+ also expects you to know that cat can do more than display; it can concatenate files and redirect output, but for this question the key function is simply viewing a file.
Therefore, the correct command is cat (B).
NEW QUESTION # 40
A technician notices that the weekly backup is taking too long to complete. The daily backups are incremental. Which of the following would most likely resolve the issue?
- A. Performing incremental weekly backups
- B. Running synthetic full weekly backups
- C. Changing the backup window
- D. Increasing the backup storage
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
A synthetic full backup combines the last full backup with subsequent incremental backups to create a new full backup without re-reading data from the source system. This method significantly reduces the backup window and network impact. It is especially useful when traditional full backups are too time-consuming.
A). Changing the backup window only shifts timing, not duration.
B). Incremental weekly backups would lack a proper full recovery point and aren't ideal alone.
C). Storage space isn't the bottleneck in backup speed-it's read/write operations and network load.
Reference:
CompTIA A+ 220-1102 Objective 4.2: Summarize backup and recovery concepts.

Answer: D
Explanation:
Requiring another employee to be present during server configuration is a control designed to prevent or detect malicious actions from an internal employee, mitigating insider threats.
NEW QUESTION # 42
A user calls the help desk to report an issue with their smartphone. After the user returns from a business trip, the user is no longer able to access email or visit websites without a Wi-Fi connection on the smartphone.
Which of the following would the user do to most likely resolve the issue?
- A. Disconnect the VPN.
- B. Reinstall the SIM card.
- C. Increase data limits.
- D. Enable cellular data.
Answer: D
Explanation:
If the phone works on Wi-Fi but not off Wi-Fi, the most likely issue is that cellular data is disabled (or restricted). This aligns directly with the CompTIA A+ objective language for mobile troubleshooting, which explicitly includes "wireless/cellular data network (enable/disable)." After travel, users often enable airplane mode or disable cellular data to avoid roaming charges, and sometimes forget to re-enable it.
Quentin Docter's mobile connectivity discussion repeatedly distinguishes Wi-Fi access from cellular connectivity and treats cellular settings as a primary area to verify when Internet access is not available away from Wi-Fi. While data caps/limits could throttle service, they usually don't make all non-Wi-Fi browsing and email impossible immediately. VPN issues might block some access, but the simplest "most likely" resolution based on the symptom is re-enabling cellular data. Reinstalling the SIM is possible, but again not the first, most likely fix given the scenario framing. Therefore, Enable cellular data (A) is correct.
NEW QUESTION # 43
Which of the following is a protocol that provides AAA for network services?
- A. RADIUS
- B. TKIP
- C. Kerberos
- D. WPA3
Answer: A
Explanation:
RADIUS (Remote Authentication Dial-In User Service)provides centralized Authentication, Authorization, and Accounting (AAA) for users who connect and use a network service.
FromQuentin Docter - CompTIA A+ Complete Study Guide:
"RADIUS is a widely used protocol for implementing AAA in network environments, allowing centralized control over user access and accounting."
NEW QUESTION # 44

- A. Contact the airport IT department
- B. Tell the employee that company policy prohibits connection to public Wi-Fi
- C. Reconnect to the network and read the pop-up carefully
- D. Look for a wall socket with RJ45 and try to connect
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Public Wi-Fi networks often usecaptive portals, which require accepting terms or authenticating via the pop- up page before full access is granted. Closing it prematurely stops full connection.
FromTravis Everett - All-in-One Exam Guide:
"Captive portals intercept the first HTTP request and present a login or acknowledgment screen. Without completing it, access is denied."
