300-740 Exam Dumps : Designing and Implementing Secure Cloud Access for Users and Endpoints (SCAZT)

The Secure Cloud Analytics alert indicates suspicious heartbeat-based connections from an internal server (ip-10-201-0-16) to multiple suspicious IPs over UDP/port 53 (DNS). This behavior suggests command-and-control (C2) activity or botnet communications.

B: Alerting the incident response (IR) team is a critical next step in escalating a verified threat as per SCAZT Section 6 (Threat Response, Pages 114–117).

D: Blocking the identified malicious IPs on perimeter firewalls or network access control devices is an appropriate containment step to disrupt communication.

Reinstallation (A/E) is premature without a full forensic investigation. Validating IDS logs (C) is useful but not immediate response-focused compared to actions B and D.

Rule 3 allows all traffic (including SSH) from 10.1.0.0/30 during the hours of 18:00–08:00, which directly conflicts with Rule 1 that is intended to deny SSH at those same hours. Since firewall rules are evaluated top-down and Rule 3 allows traffic during the exact period where SSH should be blocked, deleting Rule 3 will allow Rule 1 to apply correctly.

This behavior is explained in SCAZT Section 3 (Network and Cloud Security, Pages 72–75), where rule precedence and time-based evaluation logic are discussed.

According to the SCAZT guide, the “Always-on” deployment mode for Cisco Secure DDoS (including integration with Secure Web Application Firewall solutions) provides continuous protection for both volumetric and application-layer attacks. This deployment model ensures that all traffic flows through the scrubbing and WAF infrastructure without requiring traffic redirection only during attack events. It provides real-time mitigation and immediate detection, which is essential to address both volumetric attacks (e.g., SYN floods) and Layer 7 (application-layer) attacks such as HTTP floods and injection-based threats.

While “Hybrid” and “On-demand” modes are useful for specific use cases, only “Always-on” offers continuous and comprehensive protection required for environments that demand consistent uptime and threat prevention.
