CompTIA N10-009 Dumps Questions Answers

An evil twin attack is when an attacker sets up a rogue access point (AP) with the same SSID as a legitimate one to trick users into connecting. Once users connect, attackers often present fake login pages or capture unencrypted session data to steal login credentials.

A. DNS poisoning manipulates DNS resolution but is not inherent to evil twin.

C. ARP spoofing is a Layer 2 attack involving MAC/IP mapping manipulation.

D. Denial of service can be a side effect but is not the primary objective of evil twin attacks.

The main purpose of an evil twin is credential theft, enabling further unauthorized access to networks or systems.

It is common for an access port to have both a voice VLAN and a data VLAN. A voice VLAN separates voice traffic from regular data traffic, ensuring better quality and security for voice communications.

The correct answer is A. ESSID . An ESSID (Extended Service Set Identifier) is used when multiple wireless access points are configured to present the same wireless network name (SSID) across a larger coverage area, such as an entire building or campus floor. This allows users to move from one location to another while remaining connected to what appears to be a single wireless network. In practice, this supports seamless roaming between APs when they are properly configured with the same SSID, compatible security settings, and coordinated channel planning.

The other options do not fit the requirement. Wireless mesh is a topology that allows APs to connect to one another wirelessly, but it does not by itself describe using one common WLAN name across all APs. Band steering pushes dual-band clients toward the 5 GHz or 6 GHz band for better performance; it is not about creating one building-wide WLAN name. WPA3 is a wireless security standard and relates to encryption and authentication, not SSID design.

The key phrase in the question is “a single wireless LAN name across the entire building” , which points directly to an ESSID deployment.
