Week 6 Checkpoint

Covers Lessons 1 through 5

Spans all five Week 6 lessons — the services that hand out addressing, translate it, address and route IPv6, and report on the running network.

Topics covered

• DHCP, DNS, and NTP
• NAT terms, types, and troubleshooting
• IPv6 addressing, types, and SLAAC
• IPv6 static and default routes
• SNMP, Syslog, file transfer, and QoS

Every question here is answerable from the first-party notes of the lessons above. You commit to an answer before you see whether it was right.

This quiz is a Week 6 milestone in its own right. Passing it does not change the completion state of any individual lesson, and you do not need it to finish the lessons it covers.
