Can I initiate a "forced failover" for my MySQL Multi-AZ DB Instance deployment? A. Only in certain regions
B. Only in VPC
C. Yes
D. No Answer: C
Explanation:
If your DB instance is a Multi-AZ deployment, you can force a failover from one availability zone to another when you select the Reboot option. When you force a failover of your DB instance, Amazon RDS automatically switches to a standby replica in another Availability Zone and updates the DNS record for the DB instance to point to the standby DB instance. As a result, you will need to clean up and re-establish any existing connections to your DB instance. Reboot with failover is beneficial when you want to simulate a failure of a DB instance for testing, or restore operations to the original AZ after a failover occurs.

Which DNS name can only be resolved within Amazon EC2? A. Internal DNS name
B. External DNS name
C. Global DNS name
D. Private DNS name Answer: D
Explanation:
Using Private Hosted Zones
If you want to access the resources in your VPC using custom DNS domain names, such as example.com, instead of using private IP addresses or AWS-provided private DNS hostnames, you can create a private hosted zone in Amazon Route 53. A private hosted zone is a container that holds information about how you want to route traffic for a domain and its subdomains within one or more VPCs without exposing your resources to the Internet. You can then create Amazon Route 53 resource record sets, which determine how Amazon Route 53 responds to queries for your domain and subdomains. For example, if you want browser requests for example.com to be routed to a web server in your VPC, you'll create an A record in your private hosted zone and specify the IP address of that web server. For more information about creating a private hosted zone, see Working with Private Hosted Zones in the Amazon Route 53 Developer Guide. QUESTION 117
