Which Cisco solution should a community college implement to fortify DNS requests?

Question

Options

• ADuo
• BDNS redundancy
• CUmbrella
• DCisco Secure Email

• A
  8% (5)
• B
  2% (1)
• C
  87% (55)
• D
  3% (2)

Explanation

Cisco Umbrella is a cloud-based Secure Internet Gateway that intercepts and inspects DNS requests before they resolve, blocking malicious domains, phishing sites, and malware at the DNS layer - making it the purpose-built solution for "fortifying DNS requests."

Why the distractors are wrong:

• A. Duo - a multi-factor authentication (MFA) solution; it secures identity/logins, not DNS traffic.
• B. DNS redundancy - a resiliency/availability strategy (multiple DNS servers to prevent outages), not a security control.
• D. Cisco Secure Email - protects against email-borne threats (spam, phishing emails); it operates at the mail layer, not the DNS layer.

Memory tip: Think "Umbrella covers everything overhead" - Umbrella sits above your network traffic at the DNS level, shielding requests before a connection is even established. If a question mentions DNS + security together, Umbrella is almost always the answer.
