Awireless routeris designed to create an access point that allows wireless devices to connect to a network. It combines the functions of a traditional router with a wireless access point, enabling communication between wired and wireless devices. These routers use Wi-Fi standards (e.g., 802.11ac, 802.11ax) to transmit data wirelessly.

Broadband routersprimarily provide internet connectivity but do not necessarily include Wi-Fi functionality unless specified.

Core routershandle large-scale data routing in the backbone of networks but are not designed for access point creation.

Inter-provider border routersfunction at an ISP level for routing traffic between different networks, not for providing user access.

This scenario describes adata exportattack, where an attacker steals sensitive information (e.g., personal data, trade secrets, or financial records) and transfers it to another entity, often for malicious purposes.

Launch pointrefers to using a compromised system for further attacks.

Denial of availabilitydisrupts access to resources.

Data modificationinvolves unauthorized changes rather than theft.

Configuring RADIUS authenticationenhances Wi-Fi security by requiring user authentication before granting access to the network. This prevents unauthorized users from connecting and mitigates risks from rogue access points.

WEPis outdated and insecure; WPA2/WPA3 with RADIUS should be used instead.

A bus topologyis a network design choice, not a security measure.

Avoiding asymmetric encryptionweakens security rather than improving it.

A violation ofintegrityoccurs whendata is modified incorrectly, whether intentionally or by accident. In this case, anemployee modifying a customer account incorrectlydemonstrates a breach of data integrity.

A and Crelate toavailability, as they describe system downtime.

Drelates toconfidentiality, as it describes improper data protection.
