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
  • 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.
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
  • 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.

Cisco Designing Cisco Security Infrastructure Sample Questions (Q52-Q57):

NEW QUESTION # 52
After a recent security breach, a financial company is reassessing their overall security posture and strategy to better protect sensitive data and resources. The company already deployed on-premises next-generation firewalls at the network edge for each branch location. Security measures must be enhanced at the endpoint level. The goal is to implement a solution that provides additional traffic filtering directly on endpoint devices, thereby offering another layer of defense against potential threats. Which technology must be implemented to meet the requirement?

Answer: D

Explanation:
When moving security closer to the data, the endpoint becomes the final perimeter. Ahost-based firewallis a software component that runs directly on the endpoint's operating system (Windows, macOS, or Linux).
While the company already has Next-Generation Firewalls (NGFWs) at the network edge, those devices cannot protect endpoints from threats originating within the same local network segment (East-West traffic) or when the device is used outside the corporate office.
Implementing a host-based firewall provides a critical layer ofdefense-in-depth. It allows security administrators to enforce strict inbound and outbound traffic rules based on applications and services specific to that device. For example, it can prevent a compromised laptop from scanning other devices on a public Wi- Fi network. In the Cisco ecosystem, this is often achieved through theCisco Secure Client(AnyConnect) using theNetwork Visibility Module (NVM)or integrated endpoint security suites.
While aDistributed Firewall(Option C) is used for micro-segmentation within data centers/clouds and aWeb Application Firewall (WAF)(Option B) protects servers from web-based attacks, only a host-based firewall meets the requirement for traffic filtering directly on the diverse array of endpoint devices. This approach ensures that even if the network edge is bypassed, the individual host remains hardened against lateral movement and unauthorized communication.


NEW QUESTION # 53
A legal services company wants to prevent remote employees from accessing personal email and social media accounts while using corporate laptops. Which security solution enforces the policy?

Answer: B

Explanation:
In the modern landscape of remote work, a legal services company must enforce acceptable use policies (AUP) regardless of where a corporate laptop is located.Cisco Umbrellais the ideal architectural solution for this requirement. Umbrella acts as a Secure Internet Gateway (SIG) that operates primarily at the DNS and web layer. When a remote employee attempts to access a personal email site or a social media platform, Umbrella intercepts the DNS request and checks it against the organization's defined security policy.
Cisco Umbrella provides granularContent Filteringcapabilities, allowing administrators to block entire categories of websites, such as "Social Networking" or "Webmail," with a single click. This enforcement happens at the edge-before a connection is even established to the malicious or unauthorized site-making it highly efficient for remote users who may not be connected to the corporate VPN. WhileCisco TrustSec (Option A) andRADIUS(Option B) are powerful for internal network segmentation and authentication, they do not inherently provide the URL/domain-based categorization required to block specific web content for remote clients. Anetwork monitoring tool(Option D) provides visibility but lacks the active enforcement mechanism to block traffic. Therefore, Cisco Umbrella is the specified technology in the SDSI objectives for cloud-delivered web security and policy enforcement for a distributed workforce.

NEW QUESTION # 54
Which two approaches support secure communication in containerized microservices architectures? (Choose two.)

Answer: A,B

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 # 55
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: C

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 # 56
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: C

Explanation:
Dependabot is a GitHub feature that automatically scans project dependencies, analyzes semantic versioning, and flags or updates components with known vulnerabilities. This prevents insecure software libraries from being introduced into the application.
