  1. Networking Fundamentals – Exam portion 15%.

In this topic, the exam tests the students’ knowledge of the basic networking topics. A student is required to know about network communication models OSI and TCP/IP protocol suite, networking topologies, IP addressing for both IPv4 and IPv6. For IPv4, the knowledge of how to carry out subnetting to meet the requirements of a network is also tested. Other considered areas include the operation of various network equipment such as firewalls and access points, as well as troubleshooting of network problems and incident management process. The certification exam also certifies the candidates’ knowledge of the operation of a cloud and its applications in an enterprise network. One must also be able to define and enumerate the pros and cons of using either the collapsed core or three-tier network architectures.

  1. LAN TechnologiesExam Portion 21%.

LAN technologies questions seek to test on areas around switching, hence, will focus on Layer 2 of the OSI model. In this section, the major emphasize is put on the operation of the switches, which include the various concepts of switching such as MAC addresses. As it is focused on Layer 2, an individual is required to understand the frame format, and size. One is also tested on VLANs operations and configurations, and the different modes in which ports can be placed and their relationship with VLANs. The exam also verifies the ability of a student to define and configure the Spanning tree protocol with its features such as PBDU. Other considered areas include EtherChannel configurations where methods of their configuring such as LCAP and PAGP are tested. The candidates should also demonstrate their understanding of the stacking and aggregation of switch in terms of the benefits of implementing the same.

  1. Routing Technologies – Exam Portion 23%.

This is the largest component tested in the exam which focuses on Layer 3 of the OSI model. In this section, the certification exam will test the individuals’ knowledge of routing fundamentals, protocols and routing tables. One is expected to know what a routing table is, its contents and how it is populated. The understanding and troubleshooting of inter-VLAN routing configuration is also examined in this topic. More emphasize is, however, placed on routing protocols, with a section on their types such as link-state and vector routing protocols. One needs to understand how to configure, verify and troubleshoot RIPv2 for IPv4, OSPFv2 and OSPFFv3 for IPV4 and IPv6, respectively, and EIGRP for both IPV4 and IPv6.

  1. WAN Technologies – Exam Portion 10%.

WAN technologies questions cover 10% of the total exam content, and test the students’ ability to define and configure the various WAN technologies. In this section, one needs to know about the WAN topologies such as point-to-point, meshed and dual/single homing. WAN technologies such as MPLS and Broadband available among others are also tested. The key protocol configure in this section is exterior BGP, eBGP with regards to single homing. An individual is also expected to understand and be able to configure tunneling specifically GRE, as well as also configure, verify and troubleshoot PPP and PPPoE. QoS is another topic tested in regards to the methods of achieving quality of service for the three types of data i.e. Voice, Video and Data.

  1. Infrastructure Services – Exam Portion 10%.

This section tests the students’ knowledge of protocols that manage the network communication. The examined areas include the operation of DNS, and how to troubleshoot issues regarding DNS configurations. One is also expected to know what DHCP is, and how to configure and verify it for both server- and router-based DHCP setups. Another considered area in this section is NTP (Network Time Protocol), its configuration and verification in client-server mode. NAT is also covered here with an emphasis on IP inside source where one needs to know how to configure, verify and troubleshoot it.

  1. Infrastructure Security – Exam Portion 11%.

In this section, the focus is on the various methods and means of implementing security in a network. This includes port level security measures such as limiting the number of MAC addresses, err-disabling ports and other security violations actions. Another security measure tested here is the use of access lists to filter traffic where one is required to know how to configure, verify and troubleshoot standard, extended and named access lists,and use APIC-EM Path Trace ACL analysis tool to troubleshoot it. The examination will also verify one’s knowledge of the various methods of securing the device by use of passwords, how to access the device i.e. SSH and Telnet, as well as the use of AAA with TACACS+ and RADIUS. This section also covers the common threats especially in the access layer and efficient ways to mitigate them.

  1. Infrastructure Management – Exam Portion 10%.

The last section in this exam focuses on the management of the network infrastructure. In this partition, the student is required to know how to configure protocols used for monitoring the device i.e. SNMP both versions 2 and 3, and Syslog. One also will be tested on the use of ICMP echo-based IP SLA in troubleshooting network connectivity issues. Another examined area is a device management where the configuration and verification knowledge of backing up and restoring the device configurations, use of LLDP protocol and licensing among other features are tested. The applicants will be able to demonstrate their understanding of the Cisco devices initial configuration, as well as their upgrade and recovery skills in case of failures or password loss. An individual should also have the knowledge of various programmable network features to describe network controllers, control and data plane, and southbound/northbound APIs.

What are you waiting for? Prepare for this certification exam, pass it with flying colors, and become a certified specialist.

Good luck!
