How do volumetric DDoS attacks differ from application-layer DDoS attacks in terms of mitigation strategies?

Volumetric attacks are mitigated through over-provisioning bandwidth, employing Content Delivery Networks (CDNs), and utilizing traffic scrubbing services that filter malicious traffic. Application-layer attacks require deeper packet inspection, behavioral analysis, and often, web application firewalls (WAFs) to identify and block malicious requests that appear legitimate.
