QuestionQ125

VerifiedSecurity Architecture and Engineering

An organization has experienced multiple distributed denial-of-service (DDoS) attacks in recent months that have affected its public-facing web and e-commerce sites, which were previously all on-premises. After analyzing the problems, network engineers recommended that the organization implement additional name service providers and redundant network paths. What is one additional recommendation that would help ensure the future availability of its web and e-commerce sites?

Explanation

A cloud provider’s service-level agreement defines expected service availability and the conditions required to meet it. Reviewing those agreements confirms whether the provider offers sufficient availability and DDoS-mitigation commitments for internet-facing workloads. Azure DDoS Protection, for example, has an SLA covering availability of the DDoS mitigation service.
