220-801 A+ study guide

The exams have been reorganized as well. 220-801, the successor to 220-701: Essentials, now focuses on hardware and networking, while 802 focuses on OS support, troubleshooting, and security. Let’s take a look at a domain-by-domain breakdown:

Test4actual 220-801 Hardware consolidates both the Hardware section from 801 and 802 and comprises 40% of the exam. In 701, the emphasis was on identification and comparison of parts, where here the focus is on configuration and installation, with a larger emphasis on BIOS configuration.

220-801 Network again consolidates the Networking categories of 701 and 702. The number of protocols, network types, and topologies covered has increased. Now included are  LDAP, SNMP, SMB, SSH, SFTP protocols; UDP; PAN and MAN networks; and mesh, ring, bus, star, and hybrid topologies. Router installation is now an explicit domain task.
