NEW QUESTION # 11
A pharmaceutical company needs a hub-and-spoke VPN topology. The design must be capable of building either partial or full mesh overlay networks. Which VPN solution must be implemented in the environment?
Answer: A
Explanation:
In the context of theDesigning Cisco Security Infrastructure (300-745 SDSI)blueprint,Dynamic Multipoint VPN (DMVPN)is the specialized architectural solution designed for scalable hub-and-spoke topologies that require the flexibility to evolve into partial or full mesh overlays. DMVPN leverages a combination of Multipoint GRE (mGRE) tunnels, Next Hop Resolution Protocol (NHRP), and IPsec encryption to create a dynamic environment.
The primary advantage of DMVPN is its ability to establish "on-demand" tunnels between spoke sites. In a traditional hub-and-spoke model, traffic between two spokes must transit the hub, which introduces latency and increases hub resource consumption. With DMVPN, spokes can use NHRP to discover the public IP addresses of other spokes and build direct tunnels between them automatically. This allows the pharmaceutical company to maintain a simple hub-and-spoke management model while benefiting from the performance of afull meshwhen traffic patterns demand it.
WhileSSL VPNs(Option D) andL2TP(Option B) are excellent for individual remote access, they are not designed for site-to-site mesh scalability.Crypto maps(Option C) represent the legacy method of building IPsec tunnels, which requires static, manual configuration of every peer relationship-making a full mesh practically impossible to manage at scale. DMVPN fulfills the Cisco SDSI objective of designing highly available and flexible secure infrastructure by automating the complexity of large-scale tunnel management.
NEW QUESTION # 12
A technology company has many remote workers who access corporate resources from various locations. The company must ensure that security policies are managed and enforced directly on endpoints, and endpoints are protected from threats regardless of location. Which firewall architecture meets the requirements?
Answer: C
Explanation:
As organizations shift toward a "borderless" or hybrid work model, the traditional perimeter-based security model becomes insufficient. When employees work from home, coffee shops, or airports, they are no longer behind the enterprise's physicalNext-Generation Firewall (NGFW)(Option A). To ensure that security policies are enforced "regardless of location," the security must move with the device.
Ahost-based firewallis a software-defined firewall that resides directly on the endpoint (laptop, workstation, or server). In the Cisco ecosystem, this is often a component ofCisco Secure ClientorCisco Secure Endpoint
. Because the firewall is local to the operating system, it can enforce strict inbound and outbound traffic rules even when the user is not connected to a VPN. This protects the device from lateral movement threats on untrusted local networks (like a public Wi-Fi) and ensures that only authorized applications can communicate over the network.
While an NGFW (Option A) provides superior deep packet inspection for the corporate perimeter, and aWeb Application Firewall (WAF)(Option C) protects web servers from application-layer attacks, neither provides the local, location-independent protection required for a distributed remote workforce. Implementing a host- based firewall aligns with theZero Trustarchitecture promoted by Cisco, where the endpoint itself becomes a micro-perimeter capable of self-protection.
NEW QUESTION # 13
A company hosted multiple applications in the Kubernetes environment, using the naming app01, app02, and so on. An app01 user could access app02 data because no security measures are implemented. The administrator decided to place each application within a separate namespace and ensure that the namespaces are completely isolated and cannot communicate with each other. Which solution must be used to accomplish the task?
Answer: B
Explanation:
In Kubernetes, a NetworkPolicy controls communication between pods and namespaces. By applying policies that deny cross-namespace traffic, the administrator can ensure each application (e.g., app01, app02) is isolated and cannot access data from other namespaces.
NEW QUESTION # 14
An oil and gas company recently faced a security breach when an employee's notepad, which contained critical login credentials, was stolen. The incident led to unauthorized access to a user account, which posed a significant risk to sensitive company data and operations. The company wants to adopt a security measure that enhances user account protection. Which action must be taken to prevent breaches like this from happening in the future?
Answer: C
Explanation:
The scenario described-where physical theft of written credentials led to a breach-is a classic failure of single-factor authentication. To mitigate this risk, the company must implementMulti-Factor Authentication (MFA). MFA requires users to provide two or more verification factors to gain access to a resource, typically categorized as something you know (password), something you have (a smartphone or hardware token), or something you are (biometrics).
According to Cisco Security Infrastructure design best practices, MFA (such asCisco Duo) ensures that even if an attacker possesses valid credentials (the "something you know" from the stolen notepad), they cannot gain access without the second factor (the "something you have"). This effectively neutralizes the threat of stolen passwords.Single Sign-On (SSO)(Option B) improves user experience and centralizes management but does not, by itself, stop an attacker who has the master password.Updating the RADIUS server(Option C) is a maintenance task that doesn't change the authentication logic, and apassword expiration policy(Option D) would only limit the "shelf life" of the stolen credentials rather than preventing their initial use. MFA is the most robust architectural control for enhancing identity security and is a core pillar of a Zero Trust framework.

NEW QUESTION # 15
A company recently discovered that a former employee, who left to join a competitor, continued to access and exfiltrate sensitive data over several weeks after leaving. The breach highlighted vulnerabilities in the organization's data security and access management practices. To prevent such incidents in the future, the organization must adopt measures that detect and restrict unauthorized data access and transfer. Which mitigation strategy must be implemented to address the issue?
Answer: B
Explanation:
The scenario describes a typical "insider threat" involvingdata exfiltration. While the initial failure was likely in the off-boarding process (Identity Management), the technical control required to specifically "detect and restrict unauthorized data access and transfer" is aData Loss Prevention (DLP) strategy. DLP solutions are designed to monitor, detect, and block sensitive data from leaving the organization's control.
A robust DLP strategy-integrated across Cisco platforms likeEmail Security (ESA),Web Security (WSA), andCisco Umbrella-works by identifying sensitive content (such as customer lists, proprietary code, or financial data) using techniques like fingerprinting or keyword matching. If an unauthorized attempt is made to upload this data to a personal cloud drive or send it via email, the DLP engine intercepts and blocks the transfer. WhileAudit Logging(Option D) is essential for forensic investigationafterthe fact, it does not
"restrict" the transfer in real-time.WAFs(Option A) protect against external attacks on web servers, and Network Policies(Option B) control traffic flow but generally lack the content-awareness required to identify sensitive business data. Implementing DLP ensures that the organization's intellectual property remains protected even if an account remains active or a user has legitimate network access.
