This will demonstrate your proficiency for section 2.3 of the Network+ 10-009 objectives. 1 / 25 What security feature in WPA3 helps protect against brute-force password attacks even if weak passwords are used? AES-128 encryption Opportunistic Wireless Encryption (OWE) Simultaneous Authentication of Equals (SAE) 802.1X port security 2 / 25 Which wireless technology would be most suitable for connecting two buildings across a parking lot with a direct line of sight? Mesh network Ad hoc connection Point-to-point wireless link Infrastructure mode 3 / 25 In wireless networks, which element is responsible for authenticating users in an enterprise environment? SSID DNS server RADIUS server DHCP server 4 / 25 What is one disadvantage of using wider wireless channels (e.g., 80 MHz or 160 MHz)? Reduced data throughput Higher power usage Increased likelihood of channel overlap and interference Incompatibility with 5 GHz networks 5 / 25 Which of the following is most likely to cause interference in the 2.4 GHz wireless band? Bluetooth devices 5 GHz access points Fiber-optic cables Gigabit Ethernet switches 6 / 25 What distinguishes a lightweight access point from an autonomous one? Lightweight APs do not support encryption Lightweight APs rely on a central controller for management Lightweight APs only support guest networks Lightweight APs are configured via CLI only 7 / 25 Which of the following is a key feature of an autonomous access point? Managed through a wireless LAN controller Requires cloud configuration Independently managed and configured Supports only 2.4 GHz frequencies 8 / 25 When would a directional antenna be most appropriate? For covering a circular area with many users For point-to-point wireless links For broadcasting to multiple floors in a building For short-range indoor environments 9 / 25 Which antenna type radiates signal in all directions equally? Directional Omnidirectional Panel Yagi 10 / 25 What is the purpose of a guest wireless network? To offer unrestricted LAN access To allow visitors to access the internal server To isolate guest traffic from internal LAN resources To extend the range of the main SSID 11 / 25 Which of the following best describes a captive portal? A physical wall jack for Ethernet A login page presented before granting internet access A firewall rule blocking MAC addresses A router configuration backup tool 12 / 25 What is the main difference between WPA2-PSK and WPA2-Enterprise? PSK uses a shared password; Enterprise uses a RADIUS server for authentication Enterprise requires 802.11n or higher PSK requires MAC filtering Enterprise does not support encryption 13 / 25 What is a major benefit of using WPA3 over WPA2 in a wireless environment? WPA3 allows for static IP assignment WPA3 uses stronger encryption and provides forward secrecy WPA3 eliminates the need for a password WPA3 supports WEP compatibility 14 / 25 Which wireless topology uses an access point to provide centralized connectivity to the network? Ad hoc Infrastructure Point-to-point Peer-to-peer 15 / 25 What defines a mesh wireless network? Devices connect through a central hub Every device communicates through wired backhaul Nodes forward traffic dynamically between one another Only the main router connects to the internet 16 / 25 Which network type allows wireless devices to connect directly to each other without an access point? Mesh Infrastructure Ad hoc Point-to-multipoint 17 / 25 What does an Extended Service Set Identifier (ESSID) consist of? One SSID tied to a single access point Multiple SSIDs in a mesh A group of access points sharing the same SSID An SSID tied to the WAN interface 18 / 25 What does the Basic Service Set Identifier (BSSID) represent? The router’s WAN IP address The frequency channel in use The MAC address of the wireless access point The name of the wireless network 19 / 25 Which of the following best defines an SSID? The MAC address of a wireless access point The name broadcast by a wireless network The encryption key used for authentication The frequency band used 20 / 25 What does band steering do in a dual-band wireless network? Blocks 2.4 GHz clients from connecting Directs capable devices to the 5 GHz or 6 GHz band for better performance Forces all devices to connect on 2.4 GHz for compatibility Enables WPA3 encryption 21 / 25 Which frequency band is newly adopted and offers wider channels and less interference? 2.4 GHz 5 GHz 6 GHz 900 MHz 22 / 25 Which frequency band offers the best range but the fewest non-overlapping channels? 5 GHz 6 GHz 2.4 GHz 60 GHz 23 / 25 Which wireless standard was introduced specifically to address regulatory requirements such as Dynamic Frequency Selection (DFS) and Transmit Power Control (TPC)? 802.11n 802.11ac 802.11h 802.11ax 24 / 25 What is the primary purpose of increasing the channel width on a wireless network? To reduce power consumption To increase available bandwidth To improve security To isolate guest traffic 25 / 25 Which of the following is a non-overlapping channel in the 2.4 GHz frequency band (in the U.S.)? Channel 4 Channel 6 Channel 8 Channel 10 Your score is 0% Restart quiz Return to CompTia N+ 10-009 Objectives
