Explanation
The best strategy to migrate the current on-premises workloads to the public cloud for the company that requires at least 80 instances running at all times and wants the workload to be highly available and cost-effective is to create /26 subnets in two regions and run 40 instances on each one. A /26 subnet can accommodate up to 62 hosts, which is enough for 40 instances. By creating subnets in two regions, the company can achieve high availability and redundancy in case one region fails due to a catastrophe. By running 40 instances on each subnet, the company can meet the minimum requirement of 80 instances and also save on costs by avoiding overprovisioning or underutilization of resources.

質問 # 151
A cloud engineer recently used a deployment script template to implement changes on a cloud-hosted web application. The web application communicates with a managed database on the back end. The engineer later notices the web application is no longer receiving data from the managed database. Which of the following is the MOST likely cause of the issue?
- A. Misconfiguration in the network ACL
- B. Misconfiguration in the user permissions
- C. Misconfiguration in the firewall
- D. Misconfiguration in the routing traffic
正解：A
解説：
The most likely cause of the issue is C. Misconfiguration in the network ACL. A network ACL (access control list) is a set of rules that controls the inbound and outbound traffic for a subnet or a virtual network in a cloud environment. A misconfiguration in the network ACL can block the communication between the web application and the managed database, resulting in data loss or unavailability. For example, according to the Azure SQL Database documentation1, if you use a virtual network service endpoint to secure your database, you need to configure the network ACL to allow traffic from the web application subnet to the database subnet. Otherwise, the web application will not be able to connect to the database. Similarly, according to the DigitalOcean tutorial2, if you use a managed database cluster, you need to add the web application's IP address or Droplet to the cluster's trusted sources list. Otherwise, the web application will not be able to access the database.
A misconfiguration in the user permissions, the routing traffic, or the firewall can also cause connectivity issues between the web application and the managed database, but they are less likely than a misconfiguration in the network ACL. A misconfiguration in the user permissions can prevent the web application from authenticating or authorizing with the database, but it will not affect the data transmission. A misconfiguration in the routing traffic can cause packets to be lost or delayed, but it will not block the communication entirely. A misconfiguration in the firewall can filter out unwanted traffic, but it will not affect the traffic that is allowed by the network ACL. Therefore, these are not the most likely causes of the issue. For more information on how to troubleshoot connectivity issues between a cloud-hosted web application and a managed database, you can refer to the AWS documentation3 or the Google Cloud documentation.

質問 # 155
A developer is no longer able to access a public cloud API deployment, which was working ten minutes prior.
Which of the following is MOST likely the cause?
- A. Depleted network bandwidth
- B. Invalid API request
- C. API provider rate limiting
- D. Invalid API token
正解：C
解説：
Explanation
API provider rate limiting is a restriction on the number of requests that can be made to a web service or application programming interface (API) within a certain time period. API provider rate limiting can cause a failure to access a public cloud API deployment, as it can reject or block any requests that exceed the limit.
API provider rate limiting can be used by cloud providers to control the usage and traffic of their customers and prevent overloading or abuse of their resources. API provider rate limiting is the most likely cause for the developer being unable to access a public cloud API deployment that was working ten minutes prior.
