Cisco 200-201 Actual Questions

Application-level allow list refers to the practice of specifying an index of approved applications that are permitted to be executed in a system environment or network, which means only specific files are allowed while everything else is denied by default, enhancing security.

The log in the exhibit is generated by a firewall. It shows a deny action taken on TCP traffic, specifying the source and destination addresses and ports, which is characteristic of firewall logs. Firewalls are designed to control incoming and outgoing network traffic based on predetermined security rules, and this log entry reflects the enforcement of such a rule.

An attack vector is the method or technique that an attacker uses to exploit a vulnerability in a system or network. An attack vector can be a software, hardware, or human component that can be manipulated to gain unauthorized access, execute malicious code, or cause damage. An attack surface is the sum of all the possible attack vectors that are exposed by a system or network. An attack surface can be reduced by applying security measures such as patching, hardening, firewalling, and encrypting. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 1-4; 200-201 CBROPS - Cisco, exam topic 1.1.c

Traffic mirroring is a technique that copies the traffic from a source port or VLAN to a destination port or VLAN, where it can be analyzed by a security device or tool. Traffic mirroring does not affect the original traffic flow and does not introduce any latency or modification to the packets. Inline traffic interrogation is a technique that forwards the traffic directly to the security device or tool, where it can be inspected and modified before being sent to the destination. Inline traffic interrogation can introduce latency and affect the performance of the network. References:
