Question and Answer: 143 The Cisco Enterprise Networks Solutions and Design (ENSLD) exam is a certification exam offered by Cisco Systems. It is designed to validate the knowledge and skills of network professionals in designing enterprise-level networks using Cisco technologies. Here is a breakdown of the exam's content and the topics you should be familiar with when preparing for the ENSLD exam: 1. Designing Layer 2 Infrastructure (20%) • Designing layer 2 domains, including VLANs, trunks, and EtherChannels. • Implementing spanning tree protocols, such as Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP). • Designing and implementing high availability in layer 2 networks. 2. Designing Layer 3 Infrastructure (21%) • Designing IP addressing schemes, including IPv4 and IPv6 addressing. • Designing and implementing inter-VLAN routing. • Configuring and optimizing routing protocols, such as Open Shortest Path First (OSPF) and Enhanced Interior Gateway Routing Protocol (EIGRP). • Designing and implementing high availability in layer 3 networks. 3. Designing WAN Infrastructure (21%) • Designing and implementing WAN technologies, including MPLS, DMVPN, and VPN. • Designing and implementing Internet connectivity solutions, such as broadband and dedicated Internet access. • Designing and optimizing branch office connectivity. 4. Designing Enterprise Network Security (19%) • Designing and implementing network security strategies, including firewalls, access control lists (ACLs), and secure connectivity. • Implementing secure network connectivity using Virtual Private Networks (VPNs). • Designing and implementing network access control mechanisms. 5. Designing Enterprise Network Services (19%) • Designing and implementing Quality of Service (QoS) mechanisms. • Designing and implementing multicast services. • Designing and implementing network services, such as Network Address Translation (NAT) and Dynamic Host Configuration Protocol (DHCP). 6. Evolving Technologies (1%) • Understanding emerging technologies, such as network programmability, software-defined networking (SDN), and cloud services. To prepare for the ENSLD exam, it is recommended to study Cisco's official exam resources, including books, documentation, and online training courses. Additionally, hands-on experience with Cisco networking equipment and technologies is crucial to reinforce your knowledge and skills. Please note that the exam content and weights may vary over time, so it is essential to refer to Cisco's official website for the most up-to-date information on the ENSLD exam.
