質問 # 172
A cloud engineer is troubleshooting a connectivity issue. The application server with IP 192.168.1.10 in one subnet is not connecting to the MySQL database server with IP 192.168.2 20 in a different subnet. The cloud engineer reviews the following information:
Application Server Stateful Firewall
Which of the following should the cloud engineer address lo fix the communication issue?
- A. The Application Server Subnet Routing Table
- B. The MySQL Server Subnet Routing Table
- C. The MySQL Server Stateful Firewall
- D. The Application Server Stateful Firewall
正解：C
解説：
The connectivity issue between the application server and the MySQL database server in different subnets is likely due to the MySQL Server Stateful Firewall's inbound rules. The application server has an IP of
192.168.1.10, but the MySQL server's inbound rules only permit IP 192.168.1.10/32 on port 3306. This rule allows only a single IP address (192.168.1.10) to communicate on port 3306, which is typical for MySQL.
However, if the application server's IP is not 192.168.1.10 or the application is trying to communicate on a different port, it would be blocked. To fix the communication issue, the cloud engineer should address the inbound rules on the MySQL Server Stateful Firewall to ensure that the application server's IP address and the required port are allowed. References: Based on the information provided in the question and general networking principles.

質問 # 176
A company developed an online trading platform. The engineering team selected event-based scaling for the platform's underlying resources. The platform resources scale up with every 2,000 subscribed users. The engineering team finds out that although compute utilization is low, scaling is still occurring. Which of the following statements best explains why this is the case?
- A. Event-based scaling should not track user subscriptions.
- B. Event-based scaling does not take resource load into account.
- C. Event-based scaling does not scale down resources.
- D. Event-based scaling should not be triggered at the 2,000-user frequency.
正解：B
解説：
Comprehensive and Detailed Step-by-Step Explanation:
* A. Event-based scaling does not scale down resources: Event-based scaling can scale both up and down depending on triggers.
* B. Event-based scaling should not be triggered at the 2,000-user frequency: The frequency is a design choice but doesn't explain the behavior.
* C. Event-based scaling should not track user subscriptions: Tracking users isn't inherently wrong, but it should align with resource load metrics.
* D. Event-based scaling does not take resource load into account: Event-based scaling relies on predefined triggers (e.g., user count) and doesn't dynamically assess resource utilization, leading to inefficiencies.
