This message indicates that the interface should be replaced. B. Explanation: There are several benefits of a ZPF: It is not dependent on ACLs. The router security posture is to block unless explicitly allowed. Policies are easy to read and troubleshoot with C3PL. One policy affects any given traffic, instead of needing multiple ACLs and inspection actions. It provides a method for limiting the number of MAC addresses that can be dynamically learned over a switch port.

Sometimes malware will infect a network but lie dormant for days or even weeks. Refer to the exhibit. An IDS uses signature-based technology to detect malicious packets, whereas an IPS uses profile-based technology. Explanation: The complete mediation principle of cybersecurity requires that all the access must be checked to ensure that they are genuinely allowed. Explanation: On the basis of response time and transit time, the performance of a network is measured. (Choose three.

These Multiple Choice Questions (MCQ) should be practiced to improve the Cyber Security skills required for various interviews (campus interview, walk-in interview, company interview), placements, entrance exams and other competitive examinations. Prefix lists are used to control which routes will be redistributed or advertised to other routers. (Choose two.). return traffic to be permitted through the firewall in the opposite direction. Network scanning is used to discover available resources on the network. Disabling DTP and configuring user-facing ports as static access ports can help prevent these types of attacks. Explanation: By using a superview an administrator can assign users or groups of users to CLI views which contain a specific set of commands those users can access. Protection is twofold; it needs to protect data and systems from unauthorized personnel, and it also needs to protect against malicious activities from employees. Explanation: The buffer overflow and ping of death DoS attacks exploit system memory-related flaws on a server by sending an unexpected amount of data or malformed data to the server. The IPv6 access list LIMITED_ACCESS is applied on the S0/0/0 interface of R1 in the inbound direction.
