Cisco 300-745 Exam Syllabus Topics:

TopicDetails
Topic 1
  • Artificial Intelligence, Automation, and DevSecOps: Explores AI's role in securing network infrastructure, selecting tools for automated security architectures such as SOAR, IaC, and API tooling, and integrating security into DevSecOps workflows and pipelines to minimize deployment risk.
Topic 2
  • Risk, Events, and Requirements: Covers SOC incident handling and response tools, modifying security designs to mitigate or respond to incidents, and applying frameworks like MITRE CAPEC, NIST SP 800-37, and SAFE. Includes matching regulatory and compliance requirements to business scenarios.
Topic 3
  • Secure Infrastructure: Covers selecting security approaches for endpoints, identities, email, and modern environments like hybrid work, IoT, SaaS, and multi-cloud. Includes choosing VPN
  • tunneling solutions, securing management planes, and selecting the appropriate firewall architecture based on business needs.
Topic 4
  • Applications: Focuses on selecting security solutions to protect applications and designing secure architectures for cloud-native, containerized, and serverless environments using segmentation. Also addresses security design impacts of emerging technologies like AI, ML, and quantum computing.

Cisco Designing Cisco Security Infrastructure Sample Questions (Q38-Q43):

NEW QUESTION # 38
Employees in a healthcare organization could not access their devices when they returned to work after the weekend. The security team discovered that a threat actor had encrypted the devices. Which security solution would mitigate the risk in future?

Answer: A

Explanation:
In the scenario described, the healthcare organization fell victim to aransomware attack, where devices were encrypted to extort the organization. To mitigate such risks in the future,Endpoint Detection and Response (EDR)is the essential architectural component. According to the Cisco SDSI Secure Infrastructure domain, protecting endpoints requires more than just traditional antivirus; it necessitates a solution that provides deep visibility into file behavior and process execution.
A robust EDR solution, such asCisco Secure Endpoint, continuously monitors all activity on the device.
When ransomware attempts to initiate its encryption process, the EDR can detect the malicious behavioral pattern in real-time. It can then take automated actions, such as isolating the infected host from the network and "stopping" the encryption process before it spreads. Furthermore, Cisco's EDR providesretrospective security, allowing administrators to see how the malware arrived and which other devices it touched. While Option A (Password Policies) helps prevent credential theft and Option C (DLP) prevents data theft, they do not stop the technical process of disk encryption. Only EDR provides the necessary detection and automated response capabilities to handle modern file-less and polymorphic malware threats effectively. This aligns with the Cisco SAFE goal of securing the endpoint layer against advanced persistent threats (APTs) and ransomware variants.

NEW QUESTION # 39
A logistics company wants to deploy an application in the cloud using cloud native techniques.
The company must ensure that the development, testing, and production environments are as identical as possible with the lowest risk of the development and testing environments impacting production. Which solution must be used to accomplish the task?

Answer: D

Explanation:
Using separate cloud accounts for development, testing, and production ensures strong isolation between environments. This prevents accidental impact on production while maintaining consistent, cloud-native deployments across all stages with minimal risk.


NEW QUESTION # 40
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?

Answer: A

Explanation:
802.1X provides port-based network access control, requiring devices (wired or wireless) to authenticate before gaining network access. This ensures that only authorized users and devices can connect, enforcing the BYOD policy and preventing unauthorized wired connections.


NEW QUESTION # 41
What does watermarking AI generated content prevent?

Answer: C

Explanation:
Watermarking in AI-generated content helps detect and trace synthetic media, which directly mitigates the risk of deep fakes. By embedding hidden identifiers, organizations can verify whether content was created by AI, reducing misuse for impersonation or disinformation.


NEW QUESTION # 42
A company published software that had a security vulnerability, and an attacker used the vulnerability to steal critical information from the environment. The issue was reported by the security team, and the administrator was instructed to run shift-left security tests before publishing the software. Which component of the software development pipeline must be recommended to run the tests?

Answer: D

Explanation:
In the context of theCisco SDSI v1.0blueprint, "shifting left" refers to the practice of integrating security testing as early as possible in the Software Development Life Cycle (SDLC). The most effective component of the pipeline for running these early tests isSource Code Management (SCM). By integrating security tools directly into the SCM system (such as GitHub, GitLab, or Bitbucket), developers can identify vulnerabilities while the code is still being written or during the initial commit phase.
Techniques such as Static Application Security Testing (SAST) and secret scanning are typically triggered at the SCM level through pull requests or commit hooks. This allows the security team to identify flawed logic or hardcoded credentials before the code is ever compiled or moved to the build stage. WhileContinuous Deployment(Option A) handles the final release of the software, it is too late in the pipeline for a "shift-left" approach to be most effective.Software Bill of Materials (SBOM) analysis(Option C) is a specific task focused on dependency management, andCloud Security Posture Management (CSPM)(Option B) focuses on the runtime environment rather than the application code itself. Utilizing SCM as the primary checkpoint ensures that security becomes a foundational part of the development process, reducing the risk of vulnerable software reaching production environments.
