Apologies for the lack of posts recently, however I’ve recently been studying for the AWS Advanced Networking Specialty Exam. Since re:Invent at the latter end of 2017 I’d made the decision to take a little time off of the studying but that changed when Sybex Published the AWS official study guide for the Advanced Networking Specialty. To date the book is still not available here in the UK as the release date seems to keep being delayed (perhaps due to distribution issues) but I was able to order it directly from Amazon.com in the US and get it shipped.
The book itself I thought was extremely good and covered the topics in pretty good detail and what I really liked was that it covered a number of the newer services such as PrivateLink and GuardDuty.
I also supplemented my studies with watching the additional re:Invent videos and reading the blog posts below:
- AWS re:Invent 2017: Extending Data Centers to the Cloud: Connectivity Options and Co (NET301)
- AWS re:Invent 2017: Deep Dive: AWS Direct Connect and VPNs (NET403)
- How to setup DNS resolution between on-premises networks and AWS using AWS Directory Service and Amazon Route53
- How to setup DNS resolution between on-premises networks and AWS using AWS Directory Service and Microsoft Active Directory
- How to setup DNS resolution between on-premises networks and AWS using Unbound
My own background is not in Networking and therefore I wasn’t that confident since there is no official practice exams to gauge whether or not you’re ready for the exam. Having said that with the official study guide you do get access to some flash cards and a raft of questions that check you’re knowledge and understanding of each area.
Nonetheless I successfully passed the exam on the first attempt and here are my tips based on my own experience:
- Buy the Official Study Guide – Extremely useful for Reference but covers the required content and is written by AWS Solution Architects.
- Subnetting – How to calculate the available IP Addresses given a specific subnet mask.
- Routing – Static, BGP and Multi Exit Discriminators (MED).
- Direct Connect – Public/Private VIFs, Best Practice.
- VPN – AWS Managed VPN using VGW & CGW and Customer Managed using EC2 Instances.
- VPC Endpoints – Gateway, Interface and Securing the endpoints.
- DNS – Resolution within a VPC to on-premises and vice versa
- Route53 – Public & Private Hosted Zones, Routing Policies
- Elastic Load Balancing – ELB Classic, ALB, NLB and Troubleshooting using CloudWatch.
- Core VPC fundamentals – Security Groups, NACLs, Route Tables and DHCP OptionSets.
- Network Security – CloudFront, WAF and Shield and their capabilities.
Since you require an Associate Certification to sit the exam you should have sufficient knowledge in order to handle anything that falls outside of the above list.
Next up for me will be the DevOps Professional Exam but that will wait until I’m back from vacation. Good Luck.
