NEW QUESTION # 39
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: A
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 # 40
A developer company recently implemented a testing environment based on Linux operating system. The company needs a technology solution that produces tracing and filtering capabilities in the Linux kernel. Which technology meets these requirements without modifying the kernel source code?
Answer: C
Explanation:
eBPF (extended Berkeley Packet Filter) allows tracing, filtering, and monitoring directly inside the Linux kernel without modifying the kernel source code. It provides deep visibility into system and application behavior, making it ideal for secure and efficient observability in a testing environment.
NEW QUESTION # 41
Which two approaches support secure communication in containerized microservices architectures? (Choose two.)
Answer: A,C
Explanation:
Mutual TLS (mTLS) provides encrypted communication and mutual authentication between services. A service mesh enforces centralized security policies and automates secure communication across microservices.
NEW QUESTION # 42
Refer to the exhibit.
In addition to SSL decryption, which firewall feature allows malware to be blocked?
Answer: B
Explanation:
Based on the provided exhibits, the correct firewall feature for blocking malware in this context isFile Inspection.
Inimage_4c047c.png, we see a Cisco Secure Firewall Access Control Policy rule named "Default Inspect".
This rule is configured to allow traffic from the "inside" zone to the "outside" zone while applying deep packet inspection. Crucially, the configuration includes aFile Policyfield, which is the mechanism used to perform malware analysis and file disposition lookups. By associating a File Policy with an Access Control rule, the firewall can inspect files as they transit the network, calculate their SHA-256 hash, and query the Cisco Collective Security Intelligence cloud to determine if the file is malicious, clean, or unknown.
The evidence of this feature in action is found inimage_4b1ebe.png, which shows theCisco Secure Endpoint (formerly AMP for Endpoints) Device Trajectory. The "Activity Details" pane specifically identifies a malicious file (iodnxvg.exe) categorized asW32.DFC.MalParent. While the log notes the file was not quarantined because it was in "audit only mode," the underlying technology performing the detection isFile Inspection. This feature provides the necessary visibility into the contents of encrypted or unencrypted data streams to identify and-when properly configured in a "Protect" or "Block" mode-stop the execution of malware. This aligns with the Cisco SDSI objective of building a layered defense that combines perimeter traffic control with granular file-level security.
NEW QUESTION # 43
Refer to the exhibit. In addition to SSL decryption, which firewall feature allows malware to be blocked?
Answer: B
Explanation:
In the exhibit, SSL decryption is already enabled, which allows encrypted traffic to be inspected.
To block malware hidden within decrypted traffic, the next required feature is File Inspection. This function analyzes files passing through the firewall to detect and stop malicious content.
