Packet Tracer 8.2 - Tips for CCENT Exam preparation

The 100-105 ICND1 exam has been retired by Cisco on February 23, 2020.

Cisco CCENT (ICND1) exam

The CCENT (Cisco Certified Entry Networking Technician) certification is the first stage of Cisco's certification system. This certification does validate the skills essential for entry-level network support positions. CCENT qualified individuals have the knowledge and skill to install, manage, maintain and troubleshoot a small enterprise branch network, including network security. However, while the CCENT covers basic networking knowledge; it does not get involved with the more intricate technical aspects of the Cisco routing and switching and network design.

The applicable training is Cisco ICND1 and the exam is 100-105. The CCENT certification is an interim step to Associate level or directly with CCNA and CCDA certifications.

Exam topics :

• Networking fundamentals;
• Connecting to a WAN;
• Basic security and wireless concepts;
• Routing and switching fundamentals;
• The TCP/IP and OSI models; IP addressing;
• WAN technologies;
• Operating and configuring IOS devices;
• Configuring RIPv2,
• Static and default routing;
• Implementing NAT and DHCP;
• Configuring simple networks.

Find complete information about CCENT exam topics on Cisco^TM website : https://learningnetwork.cisco.com/community/certifications/ccent/icnd1/exam-topics

Validity : CCENT certifications are valid for three years. To recertify, you have to pass either the ICND1 or ICND2 exam, or pass the current CCNA exam.

Prerequisties : No pre-qualification is necessary to take CCENT exam

Test Scheduling : Pearson VUE delivers tests for associate, professional, and expert level certifications for Cisco Systems. Select your test center and schedule your CCENT exam on Pearson VUE website.

Packet Tracer features support for CCENT exam training

The following content describes, for each CCENT exam topic, the features supported in Cisco Packet Tracer 8.2 and the IOS commands available for labs and simlets preparation.

 

1.0 Network Fundamentals

1.1 Compare and contrast OSI and TCP/IP models

Packet Tracer 8.2 simulation mode provide a view of Ethernet frames and IP packets transiting on the network with detailled information for each OSI layer. This simulation mode is very helpful for better understanding which network information is transported at each OSI level.

 

1.2 Compare and contrast TCP and UDP protocols

Packet Tracer simulation mode provides detailled view of TCP and UDP payloads which helps network beginners to better understand the key differences between TCP (connected & reliabla protocol) and UDP (stateless, not connected protocol).
