最新的 CompTIA CASP CAS-004 免費考試真題 (Q245-Q250):

問題 #245
Clients are reporting slowness when attempting to access a series of load-balanced APIs that do not require authentication. The servers that host the APIs are showing heavy CPU utilization. No alerts are found on the WAFs sitting in front of the APIs.
Which of the following should a security engineer recommend to BEST remedy the performance issues in a timely manner?

A. Implement rate limiting on the API.
B. Implement OAuth 2.0 on the API.
C. Implement input validation on the API.
D. Implement geoblocking on the WAF.

答案：B

解題說明：
Keyword here is that the API does not require authentication. OAUTH 2.0 solves that and will improve performance by only processing authenticated calls.

問題 #246
An e-commerce company is running a web server on premises, and the resource utilization is usually less than
30%. During the last two holiday seasons, the server experienced performance issues because of too many connections, and several customers were not able to finalize purchase orders. The company is looking to change the server configuration to avoid this kind of performance issue.
Which of the following is the MOST cost-effective solution?

A. Upgrade the server with a new one.
B. Move the server to a cloud provider.
C. Change the operating system.
D. Buy a new server and create an active-active cluster.

答案：B

解題說明：
Explanation
Moving the server to a cloud provider is the most cost-effective solution to avoid performance issues caused by too many connections during peak seasons, such as holidays. Moving the server to a cloud provider can provide scalability, elasticity, and availability for the web server, as it can adjust its resources and capacity according to the demand and traffic. Moving the server to a cloud provider can also reduce operational and maintenance costs, as the cloud provider can handle the infrastructure and security aspects. Changing the operating system may not help avoid performance issues, as it could introduce compatibility or functionality problems, and it may not address the resource or capacity limitations. Buying a new server and creating an active-active cluster may help avoid performance issues, but it may not be cost-effective, as it could involve hardware and software expenses, as well as complex configuration and management tasks. Upgrading the server with a new one may help avoid performance issues, but it may not be cost-effective, as it could involve hardware and software expenses, as well as migration and testing efforts.

問題 #247
A security administrator was informed that a server unexpectedly rebooted. The administrator received an export of syslog entries for analysis:

Which of the following does the log sample indicate? (Choose two.)

A. Encrypted payroll data was successfully decrypted by the attacker
B. Payroll data was exfiltrated to an attacker-controlled host
C. A root user performed an injection attack via kernel module
D. Buffer overflow in memory paging caused a kernel panic
E. Syslog entries were lost due to the host being rebooted
F. Jsmith successfully used a privilege escalation attack

答案：D,F

問題 #248
A security engineer estimates the company's popular web application experiences 100 attempted breaches per day. In the past four years, the company's data has been breached two times.
Which of the following should the engineer report as the ARO for successful breaches?

A. 36,500
B. 0
C. 1
D. 0.5

答案：D

解題說明：
Reference: https://blog.netwrix.com/2020/07/24/annual-loss-expectancy-and-quantitative-risk-analysis/ The ARO (annualized rate of occurrence) for successful breaches is the number of times an event is expected to occur in a year. To calculate the ARO for successful breaches, the engineer can divide the number of breaches by the number of years. In this case, the company's data has been breached two times in four years, so the ARO is 2 / 4 = 0.5. The other options are incorrect calculations. Verified References: https://www.
