Cisco 300-740 Dumps Questions Answers

The App Discovery function in Cisco Umbrella enables organizations to identify cloud applications in use across their environment, including unsanctioned or shadow IT services. This is crucial for risk assessments and ranking cloud services based on their risk profile.

App Discovery analyzes DNS and web traffic to detect SaaS applications and assigns a risk score to each app based on industry best practices and Cisco Talos threat intelligence.

It provides visibility into cloud service usage and supports decisions about which applications should be allowed, restricted, or blocked.

Key Statement: "App Discovery helps identify cloud applications in use and provides risk ratings for each, allowing organizations to apply governance policies to risky or unsanctioned cloud services."

Rule 1 is a “deny all” rule placed at the top of the access control policy. Because Cisco firewalls process rules sequentially from top to bottom, Rule 1 is blocking all traffic—including RDP (Rule 2) and HTTPS (Rule 3). To allow specific traffic, the “deny all” catch-all rule should be placed last so that the specific allow rules are evaluated first.

SCAZT Section 3 (Network and Cloud Security, Pages 69–74) discusses rule hierarchy and clearly states that allow rules must precede any general deny policies to ensure intended traffic is matched correctly. This best practice is essential when dealing with multi-cloud access control.

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.
