You work for an international corporation that uses AWS. Due to regulations, you are now required to route the US and China to two different websites. You set up the records and now no other countries can access your site.Why is this?

  1. You forgot to set a default geolocation record.
  2. You probably broke your DNS.
  3. You must have a geolocation in place for every country.
  4. Geolocation features are only available in CloudFront.

Answer(s): A

Explanation:

A default record is required for traffic that does not match a geolocation criteria to follow.



Your company is expanding its cloud infrastructure and moving many of its flat files and static assets to S3. You currently use a VPN to access your compute infrastructure, but you require more reliability for your static files as you are offloading all of your important data to AWS. What is your best course of action while keeping costs low?

  1. Create a Direct Connect connection using a Private VIF to access both compute and S3 resources.
  2. Create an S3 endpoint and create a route to the endpoint prefix list for your VPN to allow access to your S3 resources.
  3. Create two Direct Connect connections. Each connected to a Private VIF to ensure maximum resiliency.
  4. Create a Direct Connect connection using a Public VIF and route your VPN over the DX connection to your VPN endpoint.

Answer(s): D

Explanation:

An S3 endpoint cannot be used with a VPN. A Private VIF cannot access S3 resources. A Public VIF with a VPN will ensure security for your compute resources and access to your S3 resources. Two DX connections are very expensive and a Private VIF still won't allow access to your S3 resources.



Your company currently has a LAG to AWS with two 1Gbps connections. What is the best way to increase throughput on this LAG?

  1. Add three 1Gbps connections to the LAG.
  2. Add one 10Gbps connections to the LAG.
  3. Configure your router to use "jumbo frames" with an MTU of 9001.
  4. Add two 1Gbps connections to the LAG.

Answer(s): D

Explanation:

Add two 1Gbps connections to the LAG. DX does not support jumbo frames, a LAG only supports 4 connections, and adding a 10Gbps connection will be limited to the lowest speed of 1Gbps.



You have 4 Direct Connect connections from your datacenter. Site A advertises 172.16.0.0/16 AS 65000, Site B advertises 172.16.0.128/25 AS 65000 65000 65000, Site C advertises 172.0.0.0/8 AS 65000 and Site D advertises 172.16.0.0/24 AS 65000. Which site will AWS choose to reach your network?

  1. Site A: 172.16.0.0/16 AS 65000
  2. Site B: 172.16.0.128/25 AS 65000 65000 65000
  3. Site C: 172.0.0.0/8 AS 65000
  4. Site D: 172.16.0.0/24 AS 65000

Answer(s): B

Explanation:

172.16.0.128/25 AS 65000 65000 65000. The most specific prefix is always the first choice for BGP routing. Also, AWS will not accept an advertisement of a network less than /16.
