However, the DNS Response only allows a single Response, so any Qcount number over 1 is invalid and suspicious. The Question Count graphs should match the DNS Query graphs.
• When the DNS Question Count Threshold is crossed, the system begins DNS Source and Query (payload) validation. If DNS Anti-spoofing and Validations options are not enabled in a DNS Profile assigned to an SPP, no DNS Question Count mitigation will be done.
• If over-threshold DNS Question Count pass both Source and Query validation, they will be allowed and you may see Question Counts on the graph higher than the Threshold.
• Drops caused by UDP Question Count Validations are displayed in Monitor > Drops Monitor > Flood Drops > Layer 7 > DNS graph
