About Cisco 350-401 Exam
Cisco 350-401, also known as one of the certification tests that covers the implementation of Cisco enterprise network core technologies, is a mandatory requirement for earning the CCNP Enterprise certificate and the ones from the CCIE Enterprise track. The exam is designed to evaluate your knowledge and skills in implementing enterprise network technologies. These include dual-stack (IPv4 & IPv6) architecture, network assurance, automation, security, virtualization, and infrastructure. The test is aimed at those individuals looking to validate their expertise in Cisco enterprise network technologies.
According to Cisco, this exam does not have any official prerequisites. However, the candidates must understand its objectives, including all their components, before sitting for this certification test. Additionally, it is recommended that they possess a minimum of three to five years of experience in implementing enterprise network technologies.
Cisco 350-401 is a 120-minute test that is available in two languages: English and Japanese. Although Cisco does not reveal the full details of its exams, the learners can expect about 100 questions in this one. The students must also be conversant with the format of these questions. Please note that some types that may be administered during the delivery of this test include multiple choice, single answer, short answer, testlets, and simlets.
Eventually, when you are ready, don’t forget that you should register for the test to take it. Therefore, go through the Pearson VUE platform, which is the official administrator of the Cisco certification exams, and follow the process of registration. From the website, type the code of this test and select the proctored section. You will see several instructions. Follow them to complete your registration. When you have completed this process, you will receive a confirmation email stating the details of your registration, including the date and time of your exam. So, be prepared for your defining day.
You should know that Cisco 350-401 covers six different topics and each has its specific components. The percentage associated with each of them informs the weight that each objective has in the questions. This means that the sections with the higher percentages will likely have more questions than those with lower figures. The domains covered in this test are highlighted below:
- Infrastructure: 30%;
- Security: 20%;
- Architecture: 15%;
- Automation: 15%;
- Virtualization: 10%;
- Network Assurance: 10%.
Let’s look at these 6 topic areas that are covered in the 350-401 certification exam and explore their special aspects in detail.
Infrastructure: This domain focuses on infrastructure and its associated concepts. The areas of its focus include the following:

- Layer 3 concepts, which covers comparing routing concepts of OSPF and EIGRP; configuring and authenticating OSPF environments, and eBGP between closely connected neighbors;
- Wireless concepts, covering knowledge of Layer 1 concepts, AP modes, and antenna categories, as well as access point discovery, principles, use case for Layer 2 and 3 roaming, WLAN configuration, and wireless client connectivity concerns;
- IP Services, covering NTP, NAT/PAT, first-hop redundancy protocols, and multicast protocols.
Security: The areas covered in this objective are as follows:
- Configuring and verifying device access control, including the protection of lines and password as well as authorization and authentication with the use of AAA;
- Configuring and verifying the features of infrastructure security;
- Explaining REST API security;
- Configuring and verifying the features of wireless security;
- Explaining the elements of network security design.
Architecture: This section requires that the candidates demonstrate a variety of skills. These are enumerated below:
- Describe different design principles that are used within an enterprise network. These include enterprise network design, Tier 2, and Tier 3, Fabric Capacity planning, and high availability methods, such as FHRP, SSO, and redundancy;
- Evaluate the design principles of WLAN deployments. This covers skills in wireless deployment models, such as centralized, controller-based, distributed, controller-less, remote branch, and Cloud. It also focuses on location services within WLAN designs;
- Distinguish between Cloud and on-premise infrastructure deployments;
- Describe the working principles inherent in a Cisco SD-WAN solution, such as SD-WAN data plans, control elements, SD-WAN, and Traditional WAN solutions;
- Describe the working principles of a Cisco SD-Access solution, which include SD-Access data plane, control elements, and traditional campus inter-operating with SD-Access;
- Explain the concepts of wireless and wired QoS, QoS policy, and components;
- Distinguish between software and hardware switching mechanisms, including FIB vs. RIB, Process and CEF, as well as TCAM and MAC address table.
Automation: The students will be evaluated based on their ability to perform specific automation tasks. They include the following:
- Interpreting fundamental Python elements and scripts;
- Constructing an authentic JSON encoded file;
- Explain high-level principles and advantages of data modeling languages, including YANG;
- Explaining APIs for vManage and Cisco DNA Center;
- Interpreting REST API response codes;
- Constructing EEM applet for the automation of configuration, data collection, or troubleshooting.
Virtualization: This topic also measures one’s skills and knowledge as they relate to virtualization technologies. The covered areas include the following:
- Explain device virtualization technologies, including Hypervisor type one and two, virtual switching, and virtual machine;
- Configure and authenticate data paths virtualization technologies, such as IPsec tunneling, GRE, and VRF;
- Explain the concepts of network virtualization, including LISP and VXLAN.
Network Assurance: The areas of focus in this exam subject are as follows:
- Diagnosing network problems with the use of SNMP, debugs, conditional debugs, trace route, Syslog, and ping tools;
- Configuring and verifying device monitoring;
- Configuring and verifying Flexible NetFlow and NetFlow;
- Configuring and verifying IPSLA;
- Configuring and verifying RSPAN/ERSPAN/SPAN;
- Configuring and verifying RESTCONF and NETCONF;
- Describing Cisco DNA Center workflows for the application of network configuration, management, and monitoring.
