What is an ExpressRoute?
A private connection from a service provider that securely extends an organization’s on-premise infrastructure connectivity into Azure.
What are the benefits of using an ExpressRoute?
- Private
- Secure
- Faster speeds (vs Internet)
- More reliable connection
- Consistent latency
Name the four (4) ExpressRoute Connectivity models and their differences
CloudExchange (Service Provider) - cross connect from a co-located datacenter
Point-to-Point Ethernet (Service Provider) - a Layer 2 Ethernet connection
Any to Any IPVPN (Service Provider) - Azure added to existing WAN like a branch office
ExpressRoute Direct - physically connect into a peering location directly
What are the speed differences between ExpressRoute Service Provider models and ExpressRoute Direct?
Service Provider models range from 50 Mbps to 10 Gbps while ExpressRoute Direct gets up to 100 Gbps. (5, 10, 40, 100)
What are the three types of ExpressRoute SKUs?
- Local: connect to a single Azure Region
- Standard: connect to multiple regions in the same geopolitical area
- Premium: connect to all regions globally
What types of Azure Resources need to be deployed to facilitate an ExpressRoute connection?
- VNet with a subnet of type Gateway Subnet
- VNet Gateway of type “ExpressRoute”
- ExpressRoute circuit
What are the two types of ExpressRoute peering schemes and what are they most suitable for?
- Private peering: best for IaaS and PaaS hybrid connectivity (Azure VNets)
- Microsoft peering: best for SaaS and PaaS connectivity (Office 365)
What is the name given to a collocated facilities where Microsoft Enterprise Microsoft Edge (MSEE) devices are situated for connection into Microsoft’s global network?
Peering Locations aka “Meet Me” locations
What (7) factors may influence the choice of a peering location?
- Proximity to on-premises data center
- Azure region connectivity
- Service Provider availability
- Bandwidth
- Cost
- Compliance requirements
- Future growth
What are the three (3) types of Resiliency that can be configured for an ExpressRoute Circuit?
- Standard: two connections, single peering site (Active/Active)
- High (ExpressRoute Metro): two connections, through different sites
- Maximum: 4 connections with 2 connections into 2 different sites
What is ExpressRoute Global Reach?
Linking ExpressRoute circuits together to create a private network across your on-premises network locations.
** This can bypass VNets inside of Azure.
What is a common scenario to leverage ExpressRoute Global Reach?
Geographically disparate sites with different types of Service Provider connectivity that need to share a common WAN.
What are the (5) advantages of ExpressRoute Global Reach?
- Improved connectivity between on-premises sites
- Security
- Reduced latency
- Scalability
- Centralized/Simplified Network Management
What is ExpressRoute FastPath?
A feature configured on ExpressRoute circuits that routes traffic directly between on-premises and Azure virtual machines and by-passes the ExpressRoute VNet Gateway.
What are the (6) advantages of ExpressRoute FastPath?
- Improved performance
- Lower latency
- Higher throughput
- Optimized routing
- Reliability
- Security
When troubleshooting an ExpressRoute circuit, what are the key status items to verify?
- ExpressRoute Circuit > Circuit Status: Enabled
- ExpressRoute Circuit > Provider Status: Provisioned
- ExpressRoute Circuit > Peering > Provisioned
- ExpressRoute Circuit > Diagnose and solve problems > Connectivity Issues
What property of an ExpressRoute Circuit is useful when a support ticket needs to be opened?
Service Key
