Cisco Updated 300-740 Exam Questions and Answers by taran

The SCAZT documentation emphasizes that when Cisco Secure XDR identifies a high-risk threat (e.g., risk score 8 out of 10 for malware distribution, as shown in the exhibit), the first priority is to prevent lateral movement and data exfiltration. The recommended first response action is to isolate the affected endpoint from the network.

Cisco Secure Endpoint and XDR allow you to trigger an "isolate" response directly from the dashboard, cutting off all non-management communication from the compromised device. This preserves the environment and enables forensic analysis before removing malware or taking destructive actions like rebuilding the system.

The exhibit shows DNS Block as the reason and lists 10.1.108.100 as the Responder IP, with the Initiator being 10.1.113.7. In Cisco Secure Firewall Management Center reports, the “Initiator IP” is the source of the request and the “Responder IP” is the source of the response. Since the DNS security intelligence engine flagged the traffic, and 10.1.108.100 was the responder, the blocked traffic corresponds to a DNS response from that IP.

A drive-by compromise occurs when malicious code is automatically downloaded and executed simply by visiting a compromised website—often through malicious advertising scripts (malvertising). According to SCAZT Section 4: Application and Data Security (Pages 85–87), ad blockers help prevent drive-by downloads by blocking these third-party ad scripts and redirections, which are commonly used in such attacks.

VPNs and private browsing modes (e.g., Incognito) do not provide protection against malicious content hosted on web pages.
