CCNP

The course is designed perfectly to cover all the aspects of CCNP and which helps you excel in the field. It consists of topics such as architecture, virtualization, infrastructure, network assurance, security, and automation.

The first part explains different design principles used in enterprise network such as tier 2, tier 3, and fabric capacity planning along with availability techniques such as redundancy, FHRP, and SSO.

It is followed by analyzing design principles of WLAN development which includes types of wireless deployment (centralized, distributed, controller-less, controller based, cloud, remote branch) and location services in a WLAN design.

This helps you to differentiate between on-premises and cloud infrastructure deployments and explains the working principles of CISCO SD-WAN solution which includes SD-WAN control and data planes elements, traditional WAN and SD-WAN solutions.

The course also explains working principles of CISCO SD-Access solution including SD-Access control & data planes elements and traditional campus interoperating with SD-Access along with explaining the concepts wired and wireless QoS such as QoS components and QoS policy.

It also allows you to differentiate between hardware and software switching mechanism such as process & CEF, MAC address table & TCAM; FIB vs. RIB.

The next module of virtualization describes device virtualization technologies and network virtualization concepts such as hypervisor type 1 & 2, virtual machine, virtual switching and LISP & VXLAN respectively; which is followed by configuring and verifying data path virtualization technologies such as VRF, and GRE & IPsec tunneling.

It is followed by layer of the infrastructure module consisting of troubleshoot static and dynamic 802.1q trunking protocols, troubleshoot static and dynamic Etherchannels along with configuring and verifying common spanning tree protocols (RSTP and MST).

The next layer explains comparing of the routing concepts of EIGRP and OSPF (advanced distance vector vs. linked state, load balancing, path selection, path operations, metrics), configuring and verifying simple OSPF environment, including multiple normal areas, summarization, and filtering (neighbor adjacency, point-to-point and broadcast network types, passive interface), eBGP between directly connected neighbors (best path selection algorithm and neighbors relationship).

The wireless part describes layer 1 concepts, such as RF power, RSSI, SNR, interference noise, band and channels, and wireless client devices capabilities, AP models, antenna types, access point discovery and join process (discovery algorithm, WLC selection process), the main principles & use cases for layer 2 & layer 3 roaming and troubleshooting WLAN configuration and wireless client connectivity issues.

The explication of IP services includes the description of network time protocol (NTP), configure and verify NAT/PAT, configure first hop redundancy protocols, such as HSRP and VRRP.

Network assurance includes diagnosing network problems using different tools such as debugs, conditional debugs, trace route, SNMP and syslog, configuring and verifying netflow and flexible netflow, SPAN/ RSPAN/ ERSPAN, device monitoring using syslog for remote logging, IPSLA, NETCONF & RESTCONF and describing CISCO DNA centre workflow to apply network configuration, monitoring and management.

The security module aids to configure and verify device access control which further includes lines and password protection, authentication and authorization using AAA, configure and verify infrastructure security features such as ACLs, CoPP along with wireless security features such as EAP, WebAuth and PSK.

Further, it also describes REST API security and the components of network security design such as threat defense, endpoint security, next generation firewall, TrustSec, MACsec and network access control with 802.1X, MAB and WebAuth.

The last module of automation includes interpretation of basic Python components and scripts, contruct valid JSON encoded file, describe the high level principles & benefits of modeling of language such as YANG; APIs for Cisco DNA centre and vManage, interpret REST API for response codes and results in payload using Cisco DNA centre and RESTCONF, construct EEM applet to automate configuration, troubleshooting or data collection and compare agent vs. agentless orchestration tools, such as, Chef, Puppet, Ansible and SaltStack.
