Question #191
A user in a home office is unable to connect to the internet. A technician asks the user to run the ipconfig command.
Which of the following first octets immediately suggests an issue with the IP address?
- A . 10
- B . 169
- C . 172
- D . 192
Correct Answer: B
B
Explanation:
An IP address starting with the first octet "169" immediately suggests an issue, indicating that the device has been assigned an Automatic Private IP Address (APIPA). APIPA addresses are self-assigned by a computer or device when it’s unable to obtain an IP address from a DHCP server, which is common in situations where the device is unable to connect to the network or the DHCP server is not functioning properly. The range for APIPA addresses is 169.254.0.1 to 169.254.255.254, and seeing an IP address within this range is a clear indicator of connectivity issues related to DHCP.
Reference: CompTIA A+ Core 1 (220-1101) Exam Objectives, specifically the networking domain that covers understanding and troubleshooting network connectivity issues, including the significance of IP address ranges such as APIPA.
Knowledge of TCP/IP networking concepts, specifically the role of DHCP in network connectivity and the implications of an APIPA address on a device’s ability to connect to the internet.

Question #192
A SOHO user’s network printer has been without power for the last few days. After turning the printer back on, the user cannot connect to it.
Which of the following is the most probable cause?
- A . The printer has a static IP address.
- B . The printer has a dynamic IP address.
- C . The printer has an APIPA.
- D . The printer has a public IP address.
Correct Answer: B
B
Explanation:
If the printer uses a dynamic IP address and has been without power, the DHCP lease may have expired, and the printer may have been assigned a new IP address. Devices attempting to connect using the old IP address will fail.
Why Not A (The printer has a static IP address): A static IP address would remain unchanged, so this would not cause the issue.
Why Not C (The printer has an APIPA): APIPA (Automatic Private IP Addressing) would occur only if the printer cannot contact the DHCP server, but this isn’t described in the scenario.
Why Not D (The printer has a public IP address): A public IP address is irrelevant in a local network scenario.

Question #194
An engineer is upgrading the power supply of a workstation to add a GPU. The current power supply is 380W, and the GPU is a six-pin power connector.
Which of the following is the minimum power supply the engineer should install?
- A . 400W
- B . 450W
- C . 500W
- D . 550W
Correct Answer: B
B
Explanation:
Upgrading a power supply to add a GPU typically requires more wattage to accommodate the additional power demands. Although the current power supply is 380W, adding a GPU with a six-pin power connector suggests a mid-range graphics card, which would likely need a total system power supply in the range of 450W to ensure adequate power for all components, providing a good balance between capacity and safety margins.
Reference: CompTIA A+ Core 1 Exam Objectives Section 3.5: Given a scenario, install or replace the appropriate power supply.

Question #195
A technician configured a new SOHO router for a small business. The ISP gave the technician an IP address on the router’s WAN port.
Which of the following addresses did the technician most likely configure on the router?
- A . 10.1.50.30
- B . 19.45.7.28
- C . 169.254.168.10
- D . 172.22.40.6
Correct Answer: B
B
Explanation:
This is an example of a public IP address that can be assigned by an ISP to a router’s WAN (Wide Area Network) port. A public IP address is a globally unique and routable address that allows a device to communicate with other devices on the internet. A private IP address, such as 10.1.50.30 or 172.22.40.6, is a non-routable address that is used within a local network and cannot be directly accessed from the internet. A link-local IP address, such as 169.254.168.10, is a self-assigned address that is used when a device cannot obtain a valid IP address from a DHCP server.

Question #197
To control costs a company provides a limited number or users with company phones One of these users opens a support ticket because the phone no longer allows internet Drowsing over a cellular connection. The user acknowledges that the phone worked before the user’s child streamed several movies using the device.
Which of the following describes why the phone cannot browse the Internet?
- A . The child accidentally connected to a neighbor’s WLAN
- B . The company’s group policy disabled the device
- C . The device has a data cap and has reached that limit
- D . The device’s plan has been unpaid
Correct Answer: C
C
Explanation:
It is common for companies to place a data cap on the devices they provide to their employees, to control costs. If a user has exceeded the data cap, the phone may no longer allow internet browsing over a cellular connection. This is usually because the cellular data usage has exceeded the allotted amount for the particular plan the device is on, and the service provider has temporarily suspended the data connection.
It is unlikely that the child accidentally connected to a neighbor’s WLAN because this would not affect the cellular data connection. Similarly, it is unlikely that the company’s group policy has disabled the device, as this would likely affect all devices under the same policy. If the device’s plan has been unpaid, the service provider would likely temporarily suspend all services, not just the cellular data connection.

Question #199
A technician is trying to fix a computer that fails to boot even when all the RAM is removed.
Which of the following should the technician do next to troubleshoot the issue?
- A . Inspect the motherboard for swollen capacitors.
- B . Replace the CMOS battery_
- C . Swap the power supply if it is inoperable.
- D . Check to see if the HDD power connectors are well seated
Correct Answer: C
C
Explanation:
The next step that the technician should do to troubleshoot the issue is C. Swap the power supply if it is inoperable.
A power supply is a device that converts the alternating current (AC) from the wall outlet into direct current (DC) that the computer components can use. A power supply is essential for the computer to boot and function properly. A faulty or inadequate power supply can cause various issues, such as no power, no display, random shutdowns, or beeping sounds.
In this scenario, the technician is trying to fix a computer that fails to boot even when all the RAM is removed. RAM stands for Random Access Memory, and it is a type of memory that stores data and instructions for the processor to access and process. RAM is also essential for the computer to boot and function properly. A faulty or incompatible RAM can cause various issues, such as no boot, no display, blue screen, or beeping sounds.
One of the basic troubleshooting techniques for a computer that fails to boot is to remove all the RAM modules and try to boot with one module at a time in different slots. This can help to identify if the problem is caused by a bad RAM module or a bad RAM slot. If the computer still fails to boot even when all the RAM is removed, it means that the problem is not related to the RAM, but to another component.
The next step that the technician should do is to swap the power supply if it is inoperable. This means that the technician should test the power supply with a multimeter or a power supply tester, and replace it with a known good one if it is faulty or insufficient. This can help to determine if the problem is caused by a bad power supply or a bad motherboard.
The other options are not the next steps that the technician should do, because they are less likely or less effective. Inspecting the motherboard for swollen capacitors (option A) may be helpful if the problem is caused by a damaged or defective motherboard, but it requires opening the computer case and visually examining the motherboard components. Replacing the CMOS battery (option B) may be necessary if the problem is caused by a low or dead CMOS battery, but it usually affects only the BIOS settings and not the boot process. Checking to see if the HDD power connectors are well seated (option D) may be useful if the problem is caused by a loose or faulty HDD connection, but it usually affects only the data access and not the boot process.
