WCNA training course description
Wireshark is a free network protocol analyser. This hands-on course provides a comprehensive tour of using Wireshark to troubleshoot networks. The course concentrates on the information needed in order to pass the WCNA exam. Students will gain the most from this course only if they already have a sound knowledge of the TCP/IP protocols.
What will you learn
Analyse packets and protocols in detail.
Troubleshoot networks using Wireshark.
Find performance problems using Wireshark.
Perform network forensics.
WCNA training course details
Who will benefit:
Technical staff looking after networks.
Prerequisites:
TCP/IP Foundation for engineers
