300-425 Question 301

Single answer

An enterprise network administrator is using Cisco DNA Center to manage their wireless network. The administrator wants to identify and troubleshoot issues affecting client devices connected to the wireless network. After accessing the Cisco DNA Center dashboard, which tool or feature should the administrator use to pinpoint problems with client connectivity and performance?

A
Client Health
B
Network Time Travel
C
Application Policy
D
Path Trace

Show answer and explanation

Correct answer: A

Explanation

The 'Client Health' feature in Cisco DNA Center is specifically designed to provide a detailed view of client device performance and connectivity. It enables administrators to quickly identify and resolve issues affecting wireless clients, making it the most suitable tool for this scenario.

A. Correct.
The 'Client Health' feature in Cisco DNA Center provides detailed insights into the connectivity and performance of client devices. It allows administrators to assess the health of individual clients and troubleshoot issues effectively.
B. Incorrect.
The 'Network Time Travel' feature allows administrators to view historical network data but is not specifically designed for troubleshooting client connectivity or performance issues.
C. Incorrect.
The 'Application Policy' feature is used to define and manage application-specific policies, but it does not provide tools for client-specific troubleshooting.
D. Incorrect.
The 'Path Trace' feature visualizes the actual path taken by packets within the network but is more relevant for analyzing end-to-end network paths rather than individual client issues.

300-425 Question 302

Single answer

An enterprise network administrator is tasked with deploying a new wireless network using Cisco DNA Center. The administrator needs to ensure that the wireless network is optimized for performance and includes automated RF management. Which feature in Cisco DNA Center should the administrator leverage to achieve this goal?

A
Assurance
B
Path Trace
C
Network Hierarchy
D
Wireless AI RF Management

Show answer and explanation

Correct answer: D

Explanation

To optimize and automate RF management in a wireless network, the administrator should leverage the Wireless AI RF Management feature in Cisco DNA Center. This feature uses artificial intelligence to dynamically adjust RF settings such as channel and power levels to improve overall performance and reduce interference. Other options like Assurance and Path Trace are useful for monitoring and troubleshooting but do not provide the automated RF optimization required for this scenario.

A. Incorrect.
Assurance provides visibility into network and client performance but does not handle automated RF management or optimization.
B. Incorrect.
Path Trace is used for troubleshooting network paths and identifying issues along the path, but it is unrelated to wireless RF management.
C. Incorrect.
Network Hierarchy is used for organizing devices and locations in Cisco DNA Center but does not include RF management capabilities.
D. Correct.
Wireless AI RF Management leverages artificial intelligence to optimize RF settings automatically and ensures wireless network performance is maintained.

300-425 Question 303

Single answer

A network administrator is tasked with configuring Cisco DNA Center to optimize the performance of a wireless network in a corporate environment. The administrator needs to ensure that the wireless network supports seamless client roaming and minimizes interference. Which feature in Cisco DNA Center should the administrator use to achieve this goal?

A
AI-Driven RRM (Radio Resource Management)
B
Assurance Dashboards
C
Path Trace Analysis
D
Wireless Client 360

Show answer and explanation

Correct answer: A

Explanation

AI-Driven RRM (Radio Resource Management) in Cisco DNA Center uses machine learning to dynamically optimize radio settings, ensuring better performance, reduced interference, and seamless client roaming. This makes it the correct choice for the scenario described.

A. Correct.
AI-Driven RRM (Radio Resource Management) is a feature in Cisco DNA Center that leverages machine learning to optimize wireless network performance, including seamless roaming and interference reduction.
B. Incorrect.
Assurance Dashboards provide visibility into network performance and health but do not actively optimize wireless settings for roaming or interference.
C. Incorrect.
Path Trace Analysis is used to troubleshoot network issues by tracing the path of packets but is not relevant for optimizing wireless performance.
D. Incorrect.
Wireless Client 360 provides detailed insights into client behavior and performance but does not actively manage or optimize the wireless network.

300-425 Question 304

Select 3

An enterprise wireless network administrator is tasked with enhancing the security of wireless LAN controllers (WLCs). Which of the following actions should the administrator take to harden the WLC against unauthorized access and potential attacks?

A
Disable unused management interfaces such as HTTP and Telnet.
B
Enable SNMPv1 for easy monitoring of the WLC.
C
Configure role-based access control (RBAC) for administrative access.
D
Change the default administrative credentials for the WLC.
E
Enable 802.1x on the management access interface for added security.

Show answer and explanation

Correct answers: A, C, D

Explanation

Device hardening involves implementing best practices to reduce security vulnerabilities. Disabling unused interfaces like Telnet and HTTP, configuring role-based access control, and changing default credentials are key steps to protect Cisco WLCs from unauthorized access and attacks. SNMPv1 and misapplied security protocols like 802.1x do not contribute to improving the security of WLC management access.

A. Correct.
Disabling unused management interfaces such as HTTP and Telnet reduces the attack surface and prevents unauthorized access via unsecure protocols. This is a recommended best practice for device hardening.
B. Incorrect.
SNMPv1 is an older protocol that is inherently insecure due to its plaintext community strings, making it a poor choice for monitoring in a secure environment. SNMPv3 should be used instead for secure monitoring.
C. Correct.
Role-based access control (RBAC) ensures that only authorized personnel with defined roles can perform specific administrative tasks. This is a key element in securing access to the WLC.
D. Correct.
Default administrative credentials are widely known and can be exploited by attackers. Changing them is a fundamental step in securing the WLC.
E. Incorrect.
While 802.1x is a secure access protocol for end-user authentication, it is not typically used for securing the management access interface of a WLC. Other methods, such as using SSH or HTTPS, are more appropriate.

300-425 Question 305

Select 3

An enterprise network administrator is tasked with improving the security of their Cisco wireless infrastructure by hardening the devices. The administrator decides to focus on management access to the wireless LAN controller (WLC). Which of the following actions should the administrator take to achieve this?

A
Disable unused management interfaces such as HTTP and Telnet on the WLC.
B
Enable HTTPS and SSH for secure management access to the WLC.
C
Use the default administrator username and password to simplify access during emergencies.
D
Configure role-based access control (RBAC) to assign appropriate privileges to administrators.
E
Enable SNMPv1 for monitoring the WLC to ensure backward compatibility with older tools.

Show answer and explanation

Correct answers: A, B, D

Explanation

Device hardening involves minimizing the attack surface and securing management access to prevent unauthorized access or interception of sensitive data. Disabling insecure or unused interfaces, enabling encrypted protocols like HTTPS/SSH, and implementing RBAC are essential steps to achieve this. Default credentials and insecure protocols like SNMPv1 should always be avoided to maintain a secure wireless network environment.

A. Correct.
Disabling unused management interfaces like HTTP and Telnet reduces the attack surface and prevents the use of insecure protocols. This is a best practice for device hardening.
B. Correct.
Enabling HTTPS and SSH ensures that management traffic is encrypted, protecting sensitive data such as credentials from being intercepted.
C. Incorrect.
Using default credentials is a critical security risk and should be avoided. Custom, strong passwords should always be configured.
D. Correct.
Configuring RBAC ensures that administrators have only the privileges they need, reducing the likelihood of accidental or intentional misuse of administrative capabilities.
E. Incorrect.
SNMPv1 is an insecure protocol that transmits data in plain text. SNMPv3 should be used for secure monitoring.
