There have been some sporadic connectivity issues on the network. Which of the following is the best choice to investigate these issues?
a. Protocol analyzer
b. Circuit-level gateway logs
c. Spam filter appliance
d. Web application firewall logs
Answer: A
Protocol analyzers help you troubleshoot network issues by gathering packet-level information across the network. These applications capture packets and can conduct protocol decoding, putting the information into readable data for analysis. Answer B is incorrect because a circuit-level gateway filters based on source and destination addresses. Answer C is incorrect because all-in-one spam filter appliances allow for checksum technology, which tracks the number of times a particular message has appeared, and message authenticity checking, which uses multiple algorithms to verify authenticity of a message. Answer D is incorrect because a web application firewall is software or a hardware appliance used to protect the organization's web server from attack.
