Week 1

This week, I felt good going into the class, despite having a full year's gap inbetween this class and SYS-255. Configuring all the boxes was a welcome refresher in the world of basic system administration and setup of different platforms. One issue I did run into was figuring out the command to display the PTR records on the AD server. I had to tinker around with the command some, but finally realized the zone was no longer the domain name, but instead the ip.in-addr-arpa zone. This finally displayed the PTR records and got me to the finish line of the lab.

Week 2

I found this week's labs interesting since I've never really tinkered with SNMP before. While a little rudimentary feeling, I think it can be useful in the system administration field, along with some supplemental security controls like logs.

Week 4

This week, our investigation into the Amazon AWS infrastructure and EC2 was new and intriguing since I had never touched their resources before. (mainly due to cost) Their ability to create a provisioned VM with your specified OS so rapidly and securely is great, especially for today's world where starting a server quickly might be crucial for a new project or launching something online. I just wish we had the resources to tinker around with some of their higher-performing VM configurations...

Week 5

This week, we took a look at Docker and containerization. Cool! I found the ease of some program installs under this system to be rather useful, and I can definitely see the use cases in multiple different areas. Now if only I was able to use this in SYS255....
