Exam N10-009 topic 1 question 248 discussion

the most likely reason preventing the users from accessing network resources is Rogue DHCP. Here’s why: Rogue DHCP refers to an unauthorized DHCP server on the network. This rogue server can assign incorrect IP addresses or network configurations to users, causing connectivity issues even if users can ping the gateway. The other options are less likely in this scenario: VLAN hopping: This is a type of network attack where an attacker sends packets to a different VLAN. It doesn't typically cause the issue described. Distributed DoS (DDoS): This attack overwhelms network resources, but users would likely experience broader network outages, not just an inability to access resources. Evil twin: This is a rogue wireless access point mimicking a legitimate one, which is more relevant to wireless network issues rather than the described scenario.

Only answer that makes sense is c

A DDoS attack would likely cause network-wide disruptions rather than affecting only a specific group of users.

Distributed DoS (DDoS): A DDoS attack overwhelms a target network with traffic from multiple devices, effectively preventing legitimate users from accessing the network. This explains why users can ping the gateway (which is reachable) but not network resources due to the high volume of traffic.
