Even the relatively good ones are bad. I have identified 60 and am on track to identify about 200 errors in the official ISC2 CISSP study guide. "However, UDP should only be used when the delivery of data is not essential" List of Layer 5 (Session) protocols: NFS SQL RPC Regarding IPv6 SLAAC: "Autoconfiguration removes the need for both DHCP and NAT." "A static packet-filtering firewall [is unable] to tell whether a packet originated from inside or outside the private network." "Examples of dedicated lines: Technology, Connection Type, Speed Digital Signal Level 0 (DS-0), Partial T1, 64 Kbps up to 1.544 Mbps Digital Signal Level 1 (DS-1), T1, 1.544 Mbps" "The web application then switches to a subject role as it queries the user's computer to retrieve a cookie" "Plenum-grade cable must be used [...] if the building has enclosed spaces that could trap gases." Stop. No. Just no. Plenum-grade cable must be used in a -plenum-. A plenum is an air-handling space like the inside of a furnace duct. The only reason we care about plenum cable in our jobs is that most offices take a shortcut and turn the entire area above the ceiling tiles in to a giant return-air duct for the air conditioner. That's why the return-air grill is simply open into the ceiling. If you burn crap in an air-handling space, the fumes aren't trapped: they almost immediately spread throughout the office. That's bad, so we use different cable than what we put under the desk where the fumes will tend to stay near where they started. Trap gases? No! Plenum is for where the gases would quickly spread!
