1. Right Answer: A
Explanation: The user can create subnets per requirement in a VPC. If the user wants to connect VPC's own data center, it can configure a VPN and only public subnet that uses the hardware VPN access to connect with its data center. When the user has configured the setup wizard, it will create a VPN gateway to route any subnet VPN traffic. Here are the valid entries for the main routing table in this scenario: Destination: 0.0.0.0/0 & Target: vgw1 2345 (to route all Internet traffic to the VPN gateway destination :. 20.0.0.0/168 target: local (Allow local routing VPC.
2. Right Answer: C
Explanation: A user can create a cloud shows alarm that takes various actions when the alarm changes state. An alarm looks at a single measurement over the period of time that the user has specified and performs one or more actions based on the value of the metric with respect to a given threshold for a number of time periods. Actions could be send notification to a subject Notification Service Amazon Simple (SMS, email, and HTTP endpoint., Notify political Auto Scaling or change the state of the instance to Stop / Terminate.
3. Right Answer: D
Explanation: At the launch of an EC2 instance, AWS recommends not select the Availability Zone (AZ. .AWS specifies that the default Availability Zone should be accepted. In fact, it allows AWS to choose the best based on availability Area system health and available capacity. If the user runs other bodies, then only one area availability must be specified. This is to specify the same or different AZ running instances.
4. Right Answer: A
Explanation: In case of failure of a planned or unplanned DB Instance, Amazon RDS automatically to a replica on standby in another Availability Zone if the user has enabled several AZ. The automatic failover mechanism simply change the DNS record of the instance DB to point to the DB standby instance. As a result, the user will restore all existing connections to the instance DB. However, as the DNS is the same, the application can access seamlessly DB.
5. Right Answer: E
Explanation: Amazon RDS provides high availability and failover support for DB instances using the Multi-AZ deployments. In a Multi-AZ deployment, Amazon RDS automatically provisions them and maintains a replica of synchronous standby in another Availability Zone. The main instance of DR is reproduced synchronously in areas of availability to a replica of standby for redundancy data, remove the I / O gel and minimize latency peaks during system backups. Running an instance of DR high availability can improve availability during planned maintenance of the system, and help protect databases against DB Instance failure and availability of disruption Zone. Note that high availability is not a scaling solution for playback scenarios only; you can not use a replica standby to serve read traffic. For read-only traffic service, you must use a read replica.
