A good change
I have never been one for change, which has in a way haunted me in my professional career. I have a tendency to get complacent in my work setting, and fail to expand the assets in which I bring to the company that writes my paycheck each week. Understandably, they requested me to pass exam Cisco 640-893: Supporting Cisco Datacenter Networking Devices. I didn't want to interrupt my life outside of work, so studying online with TestsForge was just perfect. The workload was intense, but certainly manageable even with a 9-5 career. I felt confident when it came to taking the test, and when I got my results I could not have been happier... nor could my bosses!
