Options: A. Centralized management through Cisco WLC B. Dynamic tuning protocol C. Radio Resource Management D. Standalone AP configuration Answer: C Explanation: Radio Resource Management (RRM) in Cisco Wireless networks enhances performance by dynamically optimizing power and channel assignments based on real-time conditions. Question 2 Which IPv6 address type is automatically configured on all IPv6-enabled interfaces and is only valid on the local network segment for communication between nodes on the same link? Options: A. Link-local address B. Global unicast address C. Unique local address D. Multicast address Cisco Systems Cisco Systems 350-401 PDF https://www.certification-exam.com/ Answer: A Explanation: Link-local addresses are automatically assigned to IPv6 enabled interfaces and operate only on the local link, ensuring communication with other devices on the same segment without the need for an external router. Question 3 Which layer of the OSI model is primarily responsible for providing end-to-end communication services, including error recovery and flow control? Options: A. Physical B. Data Link C. Transport D. Network Answer: C Explanation: The Transport layer is responsible for end-to-end communications, managing error recovery and flow control, ensuring reliable data transfer between devices. Question 4 Which configuration is essential when using a router-on-a-stick for inter-VLAN routing? Options: A. Configure a separate subinterface for each VLAN and apply IEEE 802.1Q encapsulation on each subinterface B. Enable STP on all router interfaces to isolate broadcast domains between VLANs C. Configure one physical interface per VLAN with no trunking protocol D. Utilize a switched virtual interface (SVI) on the router for each VLAN Answer: A Explanation: In a router-on-a-stick configuration, a single physical interface on the router is divided into multiple subinterfaces, each corresponding to a separate VLAN. The IEEE 802.1Q encapsulation method is used on each subinterface to properly tag and route traffic between VLANs. Cisco Systems Cisco Systems 350-401 PDF https://www.certification-exam.com/ Question 5 Which Quality of Service (QoS) mechanism uses packet marking in the IP header to differentiate traffic into classes for differentiated handling? Options: A. DiffServ B. IntServ C. WRED D. CBWFQ Answer: A Explanation: DiffServ (Differentiated Services) leverages the DSCP field in the IP header to classify packets for different levels of service, unlike other mechanisms such as IntServ which focuses on reservation based on flows. Question 6 When implementing security in a network, what is the primary benefit of using an Access Control List (ACL) on router interfaces? Options: A. It filters traffic based on defined rules B. It encrypts network traffic C. It provides load balancing for data flow D. It monitors network performance Answer: A Explanation: Applying an ACL to router interfaces allows you to control the traffic by permitting or denying packets based on specified criteria. This helps in preventing unauthorized access and enhancing overall network security, whereas the other options do not represent the primary function of ACLs. Question 7 When implementing a site-to-site IPSec VPN tunnel, which of the following steps is most critical to ensure that the tunnel is established correctly? Options: A. Verifying that the IKE Phase 2 parameters match on both ends Cisco Systems Cisco Systems 350-401 PDF https://www.certification-exam.com/ B. Ensuring that the correct IPsec policies are configured on both ends C. Confirming that the remote access VPN client is properly authenticated D. Checking that dynamic routing protocols are functioning correctly Answer: B Explanation: For an IPSec VPN tunnel, it is crucial to ensure that the IPsec policies—including encryption, decryption, and authentication algorithms—match on both sides of the tunnel. This alignment is essential for the successful establishment and proper functioning of the VPN. Question 8 Which benefit of network automation and programmability best supports scalable network deployments? Options: A. Streamlined configuration and reduced manual errors B. Slower and more labor-intensive processes C. Increased likelihood of human error due to code complexity D. Greater dependency on manual configuration practices Answer: A Explanation: Network automation and programmability enable consistent, repeatable configurations and reduce the occurrence of human errors, thereby supporting more efficient and scalable network operations. Question 9 Which mechanism on a Cisco router allows routes learned from one routing protocol to be injected into another routing protocol, thereby enabling interoperability between different routing domains? Options: A. Route redistribution B. Static routing C. Default routing D. Policy-based routing Answer: A Explanation: Route redistribution is the process that enables a router to take routes learned via one protocol and Cisco Systems Cisco Systems 350-401 PDF https://www.certification-exam.com/ advertise them into another routing protocol domain. This function is critical in environments where multiple routing protocols coexist, and seamless integration is required. Static routing, default routing, and policy- based routing do not provide the required dynamic inter-protocol sharing. Question 10 What is one major advantage of using a spine-leaf architecture in data center networking? Options: A. It ensures uniform low latency and high bandwidth between any two servers by directly connecting every leaf switch to all spine switches B. It centralizes traffic through a singular core switch for easier management C. It minimizes east-west traffic by implementing strict hierarchical routing protocols D. It relies on a deep network hierarchy to optimize north-south traffic only Answer: A Explanation: A spine-leaf architecture is designed such that each leaf switch is directly connected to every spine switch, thereby providing uniform low latency and ample bandwidth for any pair of servers. This flat architecture addresses the challenges of modern data center traffic patterns, making it ideal for high-performance environments. Would you like to see more?
