NEW QUESTION # 43
Which two metrics are important for evaluating the performance of automated security response workflows? (Choose two.)
Answer: B,C
Explanation:
MTTD measures how quickly incidents are detected, and MTTR measures how quickly they are resolved. Together, they indicate the effectiveness of automated security response workflows.
NEW QUESTION # 44
A bank experienced challenges with compromised endpoints gaining access to the internal network. To enhance security, the bank wants to ensure that all endpoints are scanned for compliance check before being allowed to access the network. Which action achieves the level of security and control?
Answer: D
Explanation:
Posture validation with Cisco ISE checks endpoint compliance (such as antivirus status, patches, and security configurations) before granting network access. This ensures compromised or non- compliant endpoints are denied access, directly addressing the bank's security concern.
NEW QUESTION # 45
What is a use for AI in securing network infrastructure?
Answer: D
Explanation:
In the architecture of modern security, Artificial Intelligence (AI) and Machine Learning (ML) are leveraged to move beyond reactive, signature-based defenses. One of the most significant uses of AI in securing network infrastructure is the detection ofzero-day attacks(often referred to in exam contexts as "day zero" attacks). A zero-day attack exploits a vulnerability that is unknown to the software vendor or the public, meaning no signature exists for traditional firewalls or antivirus software to block it.
AI identifies these threats throughbehavioral analysisandanomaly detection. By establishing a highly granular baseline of "normal" network traffic patterns-including flow direction, packet size, inter-packet arrival times, and protocol behavior-AI models can detect subtle deviations that indicate a malicious exploit.
For example,Cisco Secure Network Analytics(formerly Stealthwatch) andEncrypted Threat Analytics (ETA)use ML to identify the cryptographic "fingerprints" of malware even within encrypted traffic, without the need for decryption. This allows the security infrastructure to identify and mitigate threats at the moment they appear, rather than waiting for a vendor to release a signature. While load balancing (Option B), traffic shaping (Option C), and Quality of Service (Option D) are critical for network performance and availability, they are traditional traffic engineering functions that do not inherently provide the advanced threat detection capabilities offered by AI-driven security models. Within the Cisco SDSI objectives, AI is positioned as the primary technology for achieving proactive visibility and reducing the "Mean Time to Detect" (MTTD) for previously unseen vulnerabilities.
NEW QUESTION # 46
A software development company relies on GitHub for managing the source code and is committed to maintaining application security. The company must ensure that known software vulnerabilities are not introduced to the application. The company needs a capability within GitHub that can analyze semantic versioning and flag any software components that pose security risks. Which GitHub feature must be used?
Answer: B
Explanation:
In modern DevSecOps, managing third-party dependencies is a major security challenge.Dependabot(often stylized as Depend-a-bot) is the specific GitHub feature designed to automate the identification and updating of vulnerable dependencies. It works by scanning the application's manifest files (like package.json or requirements.txt) and analyzing thesemantic versioningof the included libraries.
When a known vulnerability (CVE) is reported in a specific version of a library used by the application, Dependabot flags the security risk and alerts the development team. Most importantly, it can automatically generate pull requests to upgrade the dependency to the minimum secure version that resolves the vulnerability. This ensures that the application remains secure without requiring manual tracking of every third-party component.
WhileGitHub Actions(Option C) can be used to run security scanners (like SAST tools), it is a general automation framework, not a dedicated dependency analysis tool.Artifact attestations(Option D) are used to prove the provenance and integrity of a build, andSealed boxes(Option B) is not a standard GitHub security feature related to vulnerability scanning. Utilizing Dependabot directly supports the Cisco SDSI objective of
"Securing the CI/CD pipeline" by proactively managing the Software Bill of Materials (SBOM) and ensuring that vulnerable components do not reach the production environment.
NEW QUESTION # 47
A manufacturing company recently experienced a network-down scenario due to malware spread on the management network. The company wants to implement a solution to detect and mitigate a similar threat in the future and protect the overall network. Which solution meets the requirements?
Answer: B
Explanation:
Endpoint Detection and Response (EDR) provides continuous monitoring, detection, and automated mitigation of malware at the endpoint level. By stopping threats before they spread across the management network, EDR protects the overall infrastructure from similar network- down scenarios in the future.
