NEW QUESTION # 49
A video game company identified a potential threat of a SYN flood attack, which could disrupt the online gaming services and impact user experience. The attack can overwhelm network resources by exploiting the TCP handshake process, leading to server unavailability and degraded performance. To safeguard the company's infrastructure and ensure uninterrupted service, it is essential to enhance the security measures in place. The company must implement a solution that manages and mitigates the risk of such network-based attacks. Which security product must be implemented to mitigate similar risks?
Answer: D
Explanation:
A SYN flood attack is a classic Denial-of-Service (DoS) technique that exploits the TCP three-way handshake. By sending a massive volume of SYN packets without completing the handshake, the attacker exhausts the target server's connection table.Cisco Secure Firewall(formerly Firepower) is the architectural component designed to mitigate these network-layer threats.
Cisco Secure Firewall utilizes features such asTCP InterceptandSYN Cookiesto defend against these attacks. When a SYN flood is detected, the firewall can act as a proxy for the handshake, only passing the completed connection to the backend server once the three-way handshake is verified. This prevents the server's resources from being overwhelmed by "half-open" connections.
In contrast,Cisco Web Security Appliance(Option A) is focused on web-based (HTTP/HTTPS) threats and proxying, not low-level TCP flood mitigation.Cisco Umbrella(Option B) primarily provides DNS-layer security and Secure Internet Gateway (SIG) services, which are ineffective against a direct SYN flood targeting an on-premises or cloud-hosted gaming server.Cisco Secure Endpoint(Option C) protects individual hosts from malware but cannot protect the network infrastructure or the server's TCP stack from being saturated by high-volume flood traffic. Consequently, Cisco Secure Firewall is the essential product for managing and mitigating these infrastructure-level network attacks.

NEW QUESTION # 50
A telecommunications company recently introduced a hybrid working model. Based on the new policy, employees can work remotely for 2 days per week if corporate equipment is used. The IT department is preparing corporate laptops to support users during the remote working days.
Which solution must the IT department implement that provides secure connectivity to corporate resources and protects sensitive corporate data even if a laptop is stolen?
Answer: D
Explanation:
Cisco Secure Client (formerly AnyConnect) provides secure remote connectivity through VPN, ensuring encrypted access to corporate resources. It also integrates endpoint security features, protecting sensitive corporate data even if a laptop is stolen.
NEW QUESTION # 51
A company hosted multiple applications in the Kubernetes environment, using the naming app01, app02, and so on. An app01 user could access app02 data because no security measures are implemented. The administrator decided to place each application within a separate namespace and ensure that the namespaces are completely isolated and cannot communicate with each other. Which solution must be used to accomplish the task?
Answer: B
Explanation:
In Kubernetes, a NetworkPolicy controls communication between pods and namespaces. By applying policies that deny cross-namespace traffic, the administrator can ensure each application (e.g., app01, app02) is isolated and cannot access data from other namespaces.
NEW QUESTION # 52
The network security team of a private university is conducting a comprehensive audit to evaluate the security posture across the network infrastructure. During the review, the security team found that a trusted vendor disclosed serious vulnerabilities identified in a product that plays a crucial role in the university's CI/CD pipeline. The security team must act promptly to mitigate the potential risks posed by these vulnerabilities. Which action must the security team take first in response to the disclosure?
Answer: D
Explanation:
The first step after a vulnerability disclosure is to validate whether the affected product exists in the organization's environment. This ensures the vulnerability is relevant before applying patches or notifying stakeholders, preventing wasted effort and focusing on actual exposure.
NEW QUESTION # 53
When designing security for applications distributed across multiple cloud providers, what is a key consideration?
Answer: A
Explanation:
Consistent identity and access management policies across cloud providers ensure uniform security controls and simplify governance in multi-cloud environments.
