Fiber-optic cable<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Fiber-optic cable transmits data using light rather than electrical signals, making it highly resistant to electromagnetic interference. This makes fiber useful in electrically noisy environments and for long-distance, high-bandwidth connections. Copper technologies can still provide excellent performance, but they are more susceptible to electrical interference. Fiber may require specialized transceivers, connectors, and installation techniques, and it can be more expensive than common copper cabling.<\/span><\/p>\n<p><b>Question 222.<\/b><\/p>\n<p><b>Which cable type is most commonly used for Ethernet connections in office LANs?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Fiber only<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Twisted-pair copper<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> HDMI<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> SATA<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2.

They are used to connect network devices such as computers, switches, routers, and access points. USB-A is used for peripherals, HDMI carries digital audio and video, and 3.5 mm connectors are commonly used for analog audio. Recognizing connector types is important when installing and troubleshooting network hardware.<\/span><\/p>\n<p><b>Question 224.<\/b><\/p>\n<p><b>Which network device separates different IP networks and decides where packets should be forwarded?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Keyboard<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Switch only<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Access point only<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Router**<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. Router<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A router forwards IP packets between different networks based on destination addresses and routing information. Switches primarily forward frames within a local network based on MAC addresses. Access points provide wireless connectivity but are not inherently responsible for routing. Routers commonly connect a home or business LAN to the internet or connect multiple internal networks to one another.<\/span><\/p>\n<p><b>Question 225.<\/b><\/p>\n<p><b>Which networking concept divides a larger IP network into smaller logical networks?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Subnetting<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Encryption<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Compression<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Virtualization<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. Subnetting<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Subnetting divides an IP network into smaller logical networks. It can improve address organization, reduce broadcast scope, and support security or administrative boundaries. Encryption protects confidentiality, compression reduces data size, and virtualization creates logical computing environments. Understanding basic subnetting helps explain why devices on different subnets often need a router to communicate.<\/span><\/p>\n<p><b>Question 226.<\/b><\/p>\n<p><b>Which IP protocol version uses addresses such as 192.168.1.10?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> IPv6<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> IPv4<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> DNS<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> ARP only<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. IPv4<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">IPv4 uses 32-bit addresses typically written in dotted-decimal notation, such as 192.168.1.10. IPv6 uses much larger 128-bit addresses represented in hexadecimal groups. DNS is a name-resolution service, while ARP helps map IPv4 addresses to MAC addresses on a local network. IPv4 remains widely used, although IPv6 adoption continues because IPv4 address space is limited.<\/span><\/p>\n<p><b>Question 227.<\/b><\/p>\n<p><b>Which IP protocol version uses 128-bit addresses and hexadecimal notation?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> IPv4<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> DHCP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> IPv6<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> NAT<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. IPv6<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">IPv6 uses 128-bit addresses and is commonly written as groups of hexadecimal values separated by colons. It was designed in part to address IPv4 address exhaustion and includes a vastly larger address space. IPv4 uses 32-bit dotted-decimal addresses. DHCP and NAT are networking technologies rather than IP protocol versions. IPv6 also supports modern networking features and can coexist with IPv4 in dual-stack environments.<\/span><\/p>\n<p><b>Question 228.<\/b><\/p>\n<p><b>Which protocol is used on local IPv4 networks to map an IP address to a MAC address?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> DNS<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> DHCP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> HTTPS<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> ARP**<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. ARP<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">ARP, or Address Resolution Protocol, is used on IPv4 LANs to determine the MAC address associated with a known IP address. A device can use ARP before sending an Ethernet frame to another local host or to its default gateway. DNS resolves names, DHCP provides IP configuration, and HTTPS secures web traffic. ARP operates within the local network and is essential to normal IPv4 Ethernet communication.<\/span><\/p>\n<p><b>Question 229.<\/b><\/p>\n<p><b>Which wireless frequency band has historically been more crowded because it is shared by many Wi-Fi and non-Wi-Fi devices?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> 2.4 GHz<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> 60 GHz only<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> 900 MHz only<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> 6 GHz only<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. 2.4 GHz<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The 2.4 GHz band is widely used by Wi-Fi, Bluetooth, some cordless devices, and other technologies. Because it has limited channel space and many devices use it, congestion and interference can be common. The 5 GHz and 6 GHz bands generally provide more channel options, though propagation and client support differ. Choosing the appropriate band depends on coverage, capacity, compatibility, and interference conditions.<\/span><\/p>\n<p><b>Question 230.<\/b><\/p>\n<p><b>Which wireless characteristic generally improves when a client moves closer to an access point?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Network cable length<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Received signal strength<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Printer toner level<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Disk capacity<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. Received signal strength<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">As a wireless client moves closer to an access point, the received signal is generally stronger because RF energy experiences less path loss over shorter distances. Obstacles, interference, antenna orientation, and environmental conditions can still affect the result. Printer toner, disk capacity, and cable length are unrelated. Stronger signal often helps support more reliable communication and higher data rates, although congestion can still limit performance.<\/span><\/p>\n<p><b>Question 231.<\/b><\/p>\n<p><b>Which technology allows a smartphone to share its cellular internet connection with another device over Wi-Fi?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> RAID<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> NFC only<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Mobile hotspot<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> BIOS<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. Mobile hotspot<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A mobile hotspot allows a smartphone or dedicated device to share its cellular data connection with other devices, often using Wi-Fi. Some devices can also tether through USB or Bluetooth. RAID is a storage technology, NFC is intended for very short-range communication, and BIOS is firmware. Hotspots are useful when normal Wi-Fi is unavailable, but they may consume mobile data and battery power quickly.<\/span><\/p>\n<p><b>Question 232.<\/b><\/p>\n<p><b>Which technology allows a mobile device to determine its geographic position using signals from satellites?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Bluetooth<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Wi-Fi only<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> NFC<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> GPS**<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. GPS<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">GPS uses signals from satellites to help compatible devices determine their geographic location. Smartphones, navigation devices, vehicles, and other systems commonly use GPS. Wi-Fi and cellular data may assist location services, but GPS itself is satellite-based. Bluetooth and NFC are short-range communication technologies. Location accuracy can be affected by obstacles, indoor environments, atmospheric conditions, and device capabilities.<\/span><\/p>\n<p><b>Question 233.<\/b><\/p>\n<p><b>Which mobile-device feature automatically rotates the screen when the device changes orientation?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Accelerometer<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> SSD<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> NIC<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Printer driver<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. Accelerometer<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">An accelerometer detects changes in motion and orientation and can be used to determine whether a mobile device is being held in portrait or landscape position. Operating systems use this information for automatic screen rotation and other motion-based features. SSDs provide storage, NICs provide network connectivity, and printer drivers control printers. Mobile devices may also include gyroscopes, magnetometers, proximity sensors, and other sensors.<\/span><\/p>\n<p><b>Question 234.<\/b><\/p>\n<p><b>Which mobile-device security feature can help locate, lock, or erase a lost device remotely?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Screen brightness<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Remote device management or find-my-device service<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> File compression<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Airplane mode only<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. Remote device management or find-my-device service<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Remote device management and find-my-device services can help locate lost hardware and may allow the owner or administrator to lock or erase it remotely. This reduces the risk of unauthorized access to sensitive information. Screen brightness and compression do not provide this capability. Airplane mode disables wireless radios but does not help recover or remotely secure a lost device. Strong authentication and encryption should also be enabled before a device is lost.<\/span><\/p>\n<p><b>Question 235.<\/b><\/p>\n<p><b>Which action is most appropriate before selling or giving away a storage device that contained sensitive information?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Rename the files<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Empty only the recycle bin<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Securely erase or sanitize the data<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Change the desktop wallpaper<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. Securely erase or sanitize the data<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Sensitive data should be securely erased or sanitized before a storage device is transferred to another person. Simply deleting files or emptying a recycle bin may leave recoverable data behind. Appropriate sanitization methods depend on the storage technology and organizational requirements. Encryption can also reduce risk when properly implemented, but secure disposal procedures remain important. Highly sensitive devices may require physical destruction according to policy.<\/span><\/p>\n<p><b>Question 236.<\/b><\/p>\n<p><b>Which security practice best protects data if a laptop is stolen while powered off?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Browser history clearing<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Screen saver only<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> File compression<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Full-disk encryption**<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. Full-disk encryption<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Full-disk encryption helps protect stored information if a laptop is stolen because the data remains encrypted until authorized credentials or keys are provided. A screen saver offers little protection against offline access, while file compression and browser-history clearing do not provide confidentiality. Encryption is especially important for portable devices because they are more likely to be lost or stolen. Strong authentication and secure recovery-key management should accompany disk encryption.<\/span><\/p>\n<p><b>Question 237.<\/b><\/p>\n<p><b>Which action best protects an account if the same password was accidentally entered on a phishing website?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Change the password immediately and review the account<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Ignore the incident<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Disable backups<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Reuse the same password elsewhere<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. Change the password immediately and review the account<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">If a password is entered on a phishing site, it should be treated as compromised. The user should change it through the legitimate service, review recent account activity, and confirm that multifactor authentication and recovery settings have not been altered. If the password was reused elsewhere, those accounts should also receive unique new passwords. Ignoring the incident gives the attacker more time to misuse the stolen credential.<\/span><\/p>\n<p><b>Question 238.<\/b><\/p>\n<p><b>Which action best reduces the chance that one leaked password will compromise several unrelated accounts?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Use shorter passwords<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Use a unique password for every account<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Share one password with coworkers<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Disable MFA<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. Use a unique password for every account<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Unique passwords prevent attackers from using credentials stolen from one site to access other services through credential stuffing. A password manager can help generate and securely store long, unique passwords. Reusing passwords creates a chain of risk across accounts. Multifactor authentication should also be enabled when available because it adds another layer of protection even if a password becomes known.<\/span><\/p>\n<p><b>Question 239.<\/b><\/p>\n<p><b>Which software security practice reduces exposure to known vulnerabilities in operating systems and applications?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Disable all updates<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Reuse old software indefinitely<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Apply security patches and updates<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Turn off antivirus permanently<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3.
