NEW QUESTION # 107
Which of the following network types is used for pairing a Bluetooth device to a smartphone?
- A. PAN
- B. LAN
- C. MAN
- D. WAN
Answer: A
Explanation:
Explanation
A PAN, or Personal Area Network, is the network type that is used for pairing a Bluetooth device to a smartphone. A PAN is a network that connects personal devices, such as phones, tablets, laptops, headphones, speakers, or printers, over a short distance, usually less than 10 meters or 33 feet. A PAN can use wireless technologies, such as Bluetooth, Wi-Fi, or infrared, to enable communication and data exchange between the devices. A Bluetooth PAN, also known as a piconet, can consist of up to eight devices, one of which acts as the master and the others as slaves. The master device initiates the pairing process with the other devices and controls the data transmission. The devices use radio waves in the 2.4 GHz frequency band to communicate with each other. Bluetooth is a low-power, low-cost, and secure technology that is widely used for creating PANs.

NEW QUESTION # 112
While implementing a non-carrier-grade wireless backhaul, a technician notices the current channel selection is extremely polluted with various RF signals. Upon performing a spectral analysis, the technician discovers a channel containing almost no RF pollution. Unfortunately, the technician is unable to select that channel. Which of the following is the MOST likely reason for this issue?
- A. The channel must be unlocked by the vendor.
- B. The device requires a firmware update to unlock the channel.
- C. The channel selection is defective; contact the manufacturer.
- D. The channel is reserved for licensed band use.
Answer: D
Explanation:
The most likely reason that the technician is unable to select the channel with almost no RF pollution is that it is reserved for licensed band use. Some channels are reserved for specific purposes and require a license to use. These licensed bands are typically used for critical infrastructure, public safety, or military operations, and unlicensed devices are not allowed to use them.

NEW QUESTION # 115
A technician is configuring a SOHO network. During testing, the technician receives the IP address 169.254.2.2, but the router is assigned the address scope of 192.168.1.254/24. Which of the following is most likely the cause?
- A. DNS
- B. Ipv6
- C. Ipv4
- D. DHCP
Answer: D
Explanation:
DHCP stands for Dynamic Host Configuration Protocol, which is a protocol that provides quick, automatic, and central management for the distribution of IP addresses within a network1. A DHCP server can assign IP addresses and other network information to devices that request them, such as computers, smartphones, and routers2.
The IP address 169.254.2.2 is an example of an APIPA (Automatic Private IP Addressing) address, which is a special type of IP address that devices use when they cannot obtain a valid IP address from a DHCP server3. APIPA addresses are in the range of 169.254.0.1 to 169.254.255.254, with a subnet mask of 255.255.0.03. Devices that use APIPA addresses can only communicate with other devices on the same local network that also use APIPA addresses3.
The router in the question is assigned the address scope of 192.168.1.254/24, which means it has an IP address of 192.168.1.254 and a subnet mask of 255.255.255.04. This address scope belongs to the private IP address range of 192.168.0.0 to 192.168.255.255, which is commonly used for local networks4. Devices that use private IP addresses can communicate with other devices on the same local network or across different networks through NAT (Network Address Translation)4.
The most likely cause of the technician receiving the IP address 169.254.2.2 is that the DHCP server on the router is not working properly or is not configured correctly3. This could be due to various reasons, such as a misconfigured router, a faulty cable, a firewall blocking DHCP traffic, or an exhausted pool of IP addresses3. As a result, the technician's device cannot obtain a valid IP address from the DHCP server and resorts to using an APIPA address instead3.
To fix this issue, the technician should check the router settings and make sure that the DHCP server is enabled and has enough available IP addresses to assign to devices2. The technician should also check the physical cabling and make sure it is properly connected and secured2. If the issue persists, the technician should try rebooting the router or resetting it to factory defaults2. Alternatively, the technician could manually assign a static IP address to the device that matches the router's address scope, such as 192.168.1.x/242.
NEW QUESTION # 116
A user's Windows PC is unable to connect to the network at a new branch office that the user is visiting. A technician discovers the PC is unable to ping the local gateway. Which of the following commands should the technician use next?
- A. show config
- B. ipconfig
- C. cd config
- D. ifconfig
Answer: B
Explanation:
ipconfig is a command-line tool that displays the current configuration of the network interfaces on a Windows PC. It can also be used to release and renew the IP address, flush the DNS cache, and display the routing table. If the PC is unable to ping the local gateway, the technician should use ipconfig to check the IP address, subnet mask, default gateway, and DNS servers of the PC. The technician can also use ipconfig /renew to request a new IP address from the DHCP server, or ipconfig /flushdns to clear the DNS cache.

NEW QUESTION # 117
A technician is installing new power supplies for the application engineering team's workstations. The management team has not yet made a decision about installing dual graphics cards, but they want to proceed with the project anyway. Which of the following power supplies would provide the BEST solution?
- A. 220VAC 9000J surge protector
- B. 1000W 24-pin modular power supply
- C. 500W redundant power supply
- D. 2000VA uninterruptible power supply
Answer: B
Explanation:
A 1000W 24-pin modular power supply provides enough power to support a dual graphics card configuration, which requires a significant amount of power. A modular power supply allows the technician to connect only the cables that are necessary for the current configuration, reducing cable clutter and improving airflow inside the case. This makes it easier to install and maintain the power supply.
