NEW QUESTION # 105
An organization's critical data was exfiltrated from a computer system in a cyberattack. A cloud analyst wants to identify the root cause and is reviewing the following security logs of a software web application:
Which of the following types of attacks occurred?
- A. SQL injection
- B. Cross-site scripting
- C. Reuse of leaked credentials
- D. Privilege escalation
Answer: A
Explanation:
The log entries show multiple POST requests to a login page (/login.php) with the following patterns in the parameter values:
u=administrator&p=or%201%20=1
u=admin&p=or%201%20=1
These requests indicate the use of SQL injection techniques. The use of keywords like "or
1=1"is a common SQL injection pattern used to bypass authentication by manipulating SQL statements. This suggests that an attacker tried to manipulate the application's SQL queries to gain unauthorized access.
NEW QUESTION # 106
A company uses containers to implement a web application. The development team completed internal testing of a new feature and is ready to move the feature to the production environment. Which of the following deployment models would best meet the company's needs while minimizing cost and targeting a specific subset of its users?
- A. In-place
- B. Rolling
- C. Canary
- D. Blue-green
Answer: C
Explanation:
The canary deployment model is an approach where a new feature or service is rolled out to a small subset of users before being deployed widely. This method allows the company to test the impact of the new feature in the production environment with a limited scope, minimizing risk and potential cost implications if issues arise. This approach contrasts with blue-green deployments, which involve switching between two identical environments; rolling deployments, which gradually update all instances; and in-place deployments, which update the current environment. The canary model is particularly suited for targeting specific user groups and gathering feedback before a full rollout.
NEW QUESTION # 107
A cloud developer needs to update a REST API endpoint to resolve a defect. When too many users attempt to call the API simultaneously, the following message is displayed:
Error: Request Timeout - Please Try Again Later
Which of the following concepts should the developer consider to resolve this error?
- A. TLS encryption
- B. Rate limiting
- C. Permission issues
- D. Server patch
Answer: B
Explanation:
To resolve the issue of a REST API endpoint timing out when too many users attempt to call the API simultaneously, the developer should consider implementing rate limiting. Rate limiting controls the number of requests a user can submit in a given amount of time, preventing overuse of the API resources and ensuring availability for all users.

- D. else{echostring APP_URLfloat RESPONSE_CODEstring VMhealth_checker (APP_URL, VM) {if [
http_probe (APP_URL) == 200] {stop (RESPONSE_CODE)echo VM }stop (VM)RESPONSE CODE }
Answer: C
Explanation:
Script A is designed to monitor the health of an application by checking its response code. If the application returns a 200 (OK) status, it indicates that the application is healthy. Otherwise, the script will stop the VM to address the issue, which is a common approach to handle unhealthy application states in automated environments. This script effectively achieves the goal of monitoring application health and taking corrective action when an unsuccessful code is returned.
