CompTIA Network+ N10-009 Practice Question

The scenario described is indicative of a DNS poisoning exploit, where the DNS response is manipulated to redirect legitimate traffic to malicious sites or servers. This answer is correct because DNS poisoning allows attackers to intervene in the resolution process to redirect users, inadvertently granting access to restricted or sensitive data. Each of the other choices represents different attack vectors which don't necessarily relate directly to manipulation of network responses for data interception:

• SQL injection involves inserting malicious code into SQL statements, typically affecting database-driven websites rather than network response behaviors for data redirection.
• Cross-site scripting (XSS) involves injecting malicious scripts into webpages viewed by other users, which primarily affects client-side interactions rather than network traffic redirection.
• Buffer overflow describes an exploit where an attacker overruns the buffer's boundary and overwrites adjacent memory, fundamentally different from manipulating network responses.
