Cisco ENCOR: Multicast Primer

Yes – we need to know enough about Multicast to be dangerous thanks to Cisco ENCOR. This video from my dear friend Kevin Wallace will give you MORE than you need for success in the exam. ENJOY!

Identifying the AWS Core Services!


If you are preparing for literally any level of AWS Certification, I think an excellent first step is to identify what I term core services. These services make the foundataion of AWS and they are ALWAYS the most tested areas.

I cover these services in depth in the growing list of AWS courses at CBT Nuggets! 

To simplify your locating them – I will group them just as AWS does in the main service list in your Web console.

AWS Compute

  • EC2 – Elastic Compute Cloud allows you to easily scale virtual machines for your main compute horsepower; note that an opposite approach in AWS is serverless compute with Lambda

AWS Storage

  • S3 – Simple Storage Services is object-based, key/value storage for many purposes in AWS
  • EBS – Elastic Block Store permits the use of MDD or SDD storage for many purposes, including boot volumes for EC2 instances

AWS Database

  • RDS – Relational Database Service allows you to host many database types in the cloud; this includes Oracle, MS SQL Server, and even Amazon’s own Aurora
  • DynamoDB – a NoSQL database option in the cloud that performs blazing performance and on-demand scalability
  • ElastiCache – creates in-memory caches for impressive performance interaction; this service also supports open standards in caching

AWS Networking

  • VPC – Virtual Private Cloud provides the networking components needed for an infrastructure including subsets, gateways, routing tables, and security mechanisms

AWS Management

  • CloudWatch – Permits the monitoring of key services; uses metrics and alarms for a familiar monitoring approach
  • CloudTrail – Permits the tracking of potentially all the API calls to AWS; this allows you detailed analysis of all events no matter the source – Web Console, CLI, SDK, etc.

AWS Security

  • IAM – Identity and Access Management allows the creation of users, groups, and roles for interacting securely with AWS

AWS Application Integration

  • SNS – the Simple Notification Service allows the generation of email and text notifications based on AWS events
  • SQS – the Simple Queue Service assists you in decoupling components and queuing messages between these components; this service helps the use of micro services for your processing needs
