Remove the original database instance.
Answer: C
一家公司当前正在运行由Amazon RDS MySQL数据库支持的Web应用程序。它具有每天运行且未加密的自动备份。安全审核要求对将来的备份进行加密，而将未加密的备份销毁。在销毁旧备份之前，公司将至少进行一次加密备份，应如何做才能为以后的备份启用加密？ A.为存储备份的Amazon S3存储桶启用默认加密B.修改数据库配置的“备份”部分以切换“启用加密”复选框。 C.创建数据库快照。 将其复制到加密的快照。从加密的快照还原数据库。 D.在MySQL的RDS上启用加密的只读副本。将加密的只读副本提升为主数据库。删除原始数据库实例。答案：C说明：Amazon RDS使用快照进行备份。仅当数据库已加密时，快照才会在创建时进行加密，并且只能在首次创建数据库时为数据库选择加密。在这种情况下，数据库以及快照均未加密。但是，您可以创建快照的加密副本。您可以使用该快照进行还原，该快照将创建一个启用了加密的新数据库实例。从那时起，将为所有快照启用加密。

You are in the process of creating a Route 53 DNS failover to direct traffic to two EC2 zones.
Obviously, if one fails, you would like Route 53 to direct traffic to the other region, Each region
has an ELB with some instances being distributed. What is the best way for you to configure the
Route 53 health check?
A. Route 53 doesn't support ELB with an internal health check.You need to create your own Route
53 health check of the ELB
B. Route 53 natively supports ELB with an internal health check. Turn "Evaluate target health" off
and "Associate with Health Check" on and R53 will use the ELB's internal health check.
C. Route 53 doesn't support EL B with an internal health check. You need to associate your resource
record set for the ELB with your own health check
D. Route 53 natively supports ELB with an internal health check. Turn "Evaluate target health" on
and "Associate with Health Check" off and R53 will use the ELB's internal health check.
Answer: D
您正在创建Route 53 DNS故障转移，以将流量定向到两个EC2区域。
显然，如果一个失败，您希望Route 53将流量引导到另一个区域，每个区域都有一个ELB，

答：Route 53不支持带有内部运行状况检查的ELB。您需要创建自己的ELB的Route 53运行状况检查。
B. Route 53本机支持带有内部运行状况检查的ELB。关闭“评估目标健康”并打开“与健康检查关联”，R53将使用ELB的内部健康检查。 
C. Route 53不支持带有内部健康检查的ELB。您需要将ELB的资源记录集与您自己的运行状况检查
D相关联。Route 53本机支持ELB进行内部运行状况检查。打开“评估目标健康”并关闭“与健康检查关联”，R53将使用ELB的内部健康检查

An Elastic IP address (EIP) is a static P address designed for dynamic cloud computing. With an
EIP, you can mask the failure of an instance or software by rapidly remapping the address to
another instance in your account. Your EIP is associated with your AWS account, not a particular
EC2 instance, and it remains associated with your account until you choose to explicitly release it.
By default how many ElPs is each AWS account limited to on a per region basis?

A. 1
B. 5
C. Unlimited
D. 10
Answer: B
弹性IP地址（EIP）是为动态云计算设计的静态P地址。使用EIP，

Much of your company's data does not need to be accessed often, and can take several hours for
retrieval time, so it's stored on Amazon Glacier. However someone within your organization has
expressed concerns that his data is more sensitive than the other data, and is wondering whether
the high level of encryption that he knows is on S3 is also used on the much cheaper Glacier
service. Which of the following statements would be most applicable in regards to this concern?
A. There is no encryption on Amazon Glacier, that's why it is cheaper.
B. Amazon Glacier automatically encrypts the data using AES-128 a lesser encryption method than
Amazon S3 but you can change it to AES 256 if you are willing to pay more.
C. Amazon Glacier automatically encrypts the data using AES-256, the same as Amazon S3.
D. Amazon Glacier automatically encrypts the data using AES-128 a lesser encryption method than
Amazon S3.
Answer: C
