Quality speaks for itself...

SAMPLE QUESTION:

An e-commerce company has its technology infrastructure deployed in hybrid mode with applications running in a single AWS Region as well as its on-premises data center. The company has a 10 Gbps AWS Direct Connect connection from the data center to AWS that is 70% utilized. The company wants to deploy a new flagship application on AWS that will connect with existing applications running on-premises. The application SLA requires a minimum of 99.9% network uptime between the on-premises data center and the AWS Cloud. The company has an AWS Enterprise Support plan.

Which of the following options would you recommend as the MOST cost-effective solution to address this requirement?

1. Purchase another 10 Gbps Direct Connect hosted connection through an AWS Direct Connect partner in a different Direct Connect location that terminates in the associated AWS Region. Set up a new virtual interface (VIF) to the existing VPC and use BGP for load balancing

2. Purchase another 10 Gbps Direct Connect dedicated connection from AWS in the existing Direct Connect location that terminates in the associated AWS Region. Set up a new virtual interface (VIF) to the existing VPC and use BGP for load balancing

3. Purchase two new Direct Connect hosted connections of 5 Gbps each through an AWS Direct Connect partner. Provision two virtual interfaces (VIFs) to the existing VPC on both Direct Connect connections and use BGP for load balancing. Terminate the existing 10 Gbps Direct Connect connection

4. Purchase another 10 Gbps Direct Connect dedicated connection from AWS in a different Direct Connect location that terminates in the associated AWS Region. Set up a new virtual interface (VIF) to the existing VPC and use BGP for load balancing

What's your guess? Scroll below for the answer...

Correct: 4.

Correct option:

**Purchase another 10 Gbps Direct Connect dedicated connection from AWS in a different Direct Connect location that terminates in the associated AWS Region. Set up a new virtual interface (VIF) to the existing VPC and use BGP for load balancing**

AWS Direct Connect is a cloud service solution that makes it easy to establish a dedicated network connection from your premises to AWS. Using AWS Direct Connect, you create a private connection between AWS and your data center. AWS Direct Connect is compatible with all AWS services accessible over the internet, and is available in speeds starting at 50 Mbps and scaling up to 100 Gbps.

There are two types of Direct Connect connections:

Dedicated Connection: A physical Ethernet connection associated with a single customer. Customers can request a dedicated connection through the AWS Direct Connect console, the CLI, or the API.

Hosted Connection: A physical Ethernet connection that an AWS Direct Connect Partner provisions on behalf of a customer. Customers request a hosted connection by contacting a partner in the AWS Direct Connect Partner Program, which provisions the connection.

You can use local preference BGP community tags to achieve load balancing and route preference for incoming traffic to your network. For each prefix that you advertise over a BGP session, you can apply a community tag to indicate the priority of the associated path for returning traffic.

The following local preference BGP community tags are supported:

7224:7100—Low preference

7224:7200—Medium preference

7224:7300—High preference

Local preference BGP community tags are mutually exclusive.

A Virtual Interface (VIF) is necessary to access AWS services, and can be either public, private or transit, like so:

Private virtual interface: A private virtual interface should be used to access an Amazon VPC using private IP addresses.

Public virtual interface: A public virtual interface can access all AWS public services using public IP addresses. A public virtual interface enables access to public services, such as Amazon S3.

Transit virtual interface: A transit virtual interface should be used to access one or more Amazon VPC Transit Gateways associated with Direct Connect gateways. You can use transit virtual interfaces with 1/2/5/10 Gbps AWS Direct Connect connections.

Exam alert - You should note the allowed VIF types for the various configurations of Direct Connect connections:

A Hosted Connection with a capacity of 500 Mbps or less can support one private VIF or one public VIF. A Hosted Connection with a capacity of 1 Gbps or more can support one private, public, or transit VIF. Each Hosted Connection supports a single VIF and you can obtain multiple VIFs by configuring multiple hosted connections.

Hosted VIFs can connect to public resources or an Amazon Virtual Private Cloud (Amazon VPC) in the same way as standard VIFs. However, the account that owns the VIF is different from the connection owner. Bandwidth is shared across all VIFs on the parent connection. A hosted VIF can support one private VIF or one public VIF.

A Dedicated Connection can support up to 50 public/private VIFs and 1 transit VIF.

“Uptime Target” means a percentage of Maximum Uptime in a monthly billing cycle applicable to your Included Resource, based upon meeting the Minimum Configuration Requirements. To ensure an uptime target of 99.9% as mandated in the given use case, the included resources should use virtual interfaces on Dedicated Connections at a minimum of 2 Direct Connect locations, and at least one of those Direct Connect locations uses the Associated AWS Region in which your workload is located.

Incorrect options:

**Purchase another 10 Gbps Direct Connect hosted connection through an AWS Direct Connect partner in a different Direct Connect location that terminates in the associated AWS Region. Set up a new virtual interface (VIF) to the existing VPC and use BGP for load balancing**

**Purchase two new Direct Connect hosted connections of 5 Gbps each through an AWS Direct Connect partner. Provision two virtual interfaces (VIFs) to the existing VPC on both Direct Connect connections and use BGP for load balancing. Terminate the existing 10 Gbps Direct Connect connection**

As mentioned in the explanation above, to guarantee an SLA of 99.9%, you must use dedicated Direct Connect connections and NOT hosted connections. So both these options are incorrect.

**Purchase another 10 Gbps Direct Connect dedicated connection from AWS in the existing Direct Connect location that terminates in the associated AWS Region. Set up a new virtual interface (VIF) to the existing VPC and use BGP for load balancing** - To guarantee an SLA of 99.9%, you must use dedicated Direct Connect connections at a minimum of 2 Direct Connect locations rather than a single Direct Connect location. So this option is incorrect.
