Cisco Designing Cisco Security Infrastructure Sample Questions (Q43-Q48):

NEW QUESTION # 43
Which two approaches support secure communication in containerized microservices architectures? (Choose two.)

Answer: B,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 # 44
A restaurant distribution center recently suffered a password spray attack targeting the Cisco Secure Firepower Threat Defense VPN headend. The attack attempts to gain unauthorized access by trying common passwords across many accounts. The attack poses a significant security threat to the organization's remote access infrastructure. To enhance the security of VPN setup and minimize the risk of similar attacks in the future, the IT security team must implement effective mitigation measures. Which technique effectively reduces the risk of this type of attack?

Answer: C

Explanation:
Enabling AAA authentication on the default connection profiles ensures that all VPN access attempts must go through strong authentication. This directly mitigates password spray attacks by enforcing centralized authentication controls, enabling account lockout, and supporting additional protections such as multifactor authentication.


NEW QUESTION # 45
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: C

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.

NEW QUESTION # 46
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: B

Explanation:
Endpoint Detection and Response (EDR) provides continuous monitoring, detection, and automated response to suspicious activity on devices. It can identify and stop ransomware attacks before encryption occurs, mitigating the risk of device lockouts in the future.


NEW QUESTION # 47
A product manager is focused on maintaining the security integrity of a microservice-based application as new features are developed and integrated. To ensure that known software vulnerabilities are not introduced into the product, it is crucial to implement a robust application security technique. The technique must be applied during the build phase of the software development lifecycle, which allows the team to proactively identify and address vulnerability risks before deployment. Which application security technique must be applied to accomplish the goal?

Answer: C

Explanation:
In a microservices-based architecture, applications are typically packaged into containers to ensure consistency across different environments. According to theDesigning Cisco Security Infrastructure (SDSI) objectives, securing the software development lifecycle (SDLC) requires integrating security checks as far
"left" as possible.Container scanningis the specific technique used during the build phase to inspect container images for known software vulnerabilities (CVEs) within the bundled libraries, binaries, and dependencies.
When a developer initiates a build, the container scanning tool cross-references the layers of the image against vulnerability databases. If a high-risk vulnerability is detected in a base image or a third-party library, the build can be automatically failed, preventing the vulnerable code from ever reaching the registry or production environment. This directly addresses the product manager's goal of ensuring known vulnerabilities are not introduced. WhileSecret Detection(Option A) is vital for finding leaked API keys or passwords, and Infrastructure as Code (IaC) scanning(Option C) ensures the environment configuration is secure, neither specifically targets the software vulnerabilities within the application package itself. Similarly,Open API specification analysis(Option D) focuses on the contract and security of the interface rather than the underlying software vulnerabilities. By implementing container scanning, organizations align with Cisco's DevSecOps framework, which emphasizes automated, policy-driven security within the CI/CD pipeline to maintain the integrity of cloud-native applications.
