Cisco Designing Cisco Security Infrastructure 認定 300-745 試験問題 (Q29-Q34):

質問 # 29
A construction company recently introduced a BYOD policy, where contractors can bring personal devices and connect to the wireless network. The network engineer configured a Wi-Fi network with a guest splash page to provide internet access only. Although the policy was limited to wireless devices, contractors started bringing devices that needed wired connections without authorization and connecting to the network. The network team suggested shutting down ports where unauthorized devices are connected. Which technology must be implemented to ensure that wired and wireless devices are granted network access only after successful authentication?

正解：A

解説：
To secure both wired and wireless access points against unauthorized devices, the industry-standard framework isIEEE 802.1x. This technology provides port-based network access control (PNAC), ensuring that no traffic-wired or wireless-is forwarded by the switch or access point until the device or user has been successfully authenticated by a central authority, typically a RADIUS server likeCisco Identity Services Engine (ISE).
In an 802.1x architecture, the device (Supplicant) must provide valid credentials or certificates to the switch
/AP (Authenticator). The Authenticator then communicates with the Authentication Server to verify the identity. If authentication fails, the port remains in a "closed" state, effectively preventing the unauthorized
"rogue" wired connections mentioned in the scenario. This approach is far more scalable and dynamic than manually shutting down ports or usingVACLs(Option C), which are static filters based on IP or MAC addresses.VxLANs(Option A) are used for network virtualization and overlay tunneling, whilePrivate VLANs(Option B) provide Layer 2 isolation within a subnet but do not verify identity. By implementing
802.1x, the construction company establishes a robust "gatekeeper" at the hardware level, satisfying the Cisco SDSI objective of securing the network edge through identity-based access control for a diverse set of devices.

質問 # 30
A financial company is in the process of upgrading network access across the entire company. The solution must ensure: least privilege access control access across different network segments and increased security for employees. Which solution approach must the company take?

正解：A

解説：
In the architecture of a modern secure infrastructure, achievingleast privilegeis a foundational requirement, especially for a financial institution where data sensitivity is high.Role-Based Access Control (RBAC)is the specific methodology used to restrict network access based on the roles of individual users within an enterprise. By implementing RBAC, the security team can ensure that employees only have access to the specific network segments and resources necessary for their job functions, effectively minimizing the internal attack surface.
Within the Cisco Security ecosystem, RBAC is often operationalized through tools likeCisco Identity Services Engine (ISE)usingScalable Group Tags (SGTs). Instead of relying on static IP addresses or complex Access Control Lists (ACLs) that are difficult to maintain across different segments, RBAC allows for dynamic policy enforcement. For example, a "Financial Auditor" role would automatically be granted access to the accounting segment but blocked from the development segment, regardless of where they plug into the network. WhilePKI(Option C) provides strong authentication and encryption, andNetFlow(Option A) provides visibility, neither inherently defines the "least privilege" permission structure. RBAC is the architectural approach that directly maps business requirements to technical access policies, ensuring that security is maintained across segmented environments as required by the Cisco SDSI objectives for secure infrastructure design.

質問 # 31
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?

正解：A

解説：
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.

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?

正解：A

解説：
A SYN flood attack is a type of DoS/DDoS attack targeting the TCP handshake process. The correct mitigation is deploying a Cisco Secure Firewall, which includes advanced intrusion prevention, SYN flood protection, and traffic management capabilities to prevent resource exhaustion and keep services available.


質問 # 33
An agricultural company wants to enhance the cybersecurity posture by implementing a defense-in-depth strategy to protect against polymorphic malware threats. Currently, the company's security infrastructure relies solely on a stateful traditional edge firewall that does not provide adequate protection against malware variants. Which technology must be added to the company's security architecture to achieve the goal?

正解：B

解説：
Polymorphic malware is particularly dangerous because it constantly changes its identifiable features (such as its file name or encryption keys) to evade traditional signature-based detection. A stateful traditional firewall is ineffective here as it primarily checks packet headers rather than inspecting the payload for malicious intent. To defend against these variants, aheuristics-based IPS (Intrusion Prevention System)is required.
Unlike traditional IPS systems that look for an exact match of a known threat "signature," heuristics-based systems look forsuspicious characteristicsor behaviors. For example, if a file attempts to modify system registries in a specific sequence or uses obfuscation techniques common to malware, the heuristics engine will flag and block it even if it has never seen that specific version of the malware before. This is a core component ofCisco Secure Firewall (NGFW). While aWAF(Option A) protects web applications and a Network Performance Monitor(Option C) provides visibility into traffic speeds, neither is designed to combat evolving malware. Adding a heuristics-based IPS provides the "deep packet inspection" layer necessary for a true defense-in-depth strategy, ensuring the agricultural company is protected against modern, evasive cyber threats.
