What are two top cloud-native security challenges faced by today's cloud-oriented organizations? (Choose two.)

Polymorphism is a malware evasion technique associated with endpoint threats, not a defining cloud-native security challenge.

Cloud environments span multiple regions, accounts, and third-party services, making it difficult for security teams to monitor traffic, data flows, and resource activity - creating dangerous blind spots that attackers exploit.

Establishing user roles is a routine IAM administrative task, not a top-tier security challenge unique to cloud-native architectures.

Cloud adoption increases the attack surface through public APIs, misconfigured storage buckets, ephemeral workloads, and shared infrastructure, giving adversaries more entry points compared to traditional data centers.

User credential validation is a standard authentication concern applicable to all IT environments, not a challenge specific to cloud-native operations.
