                                          NEW QUESTION # 43
                                          A security operations center analyst is using the command line to display specific traffic.
                                          The analyst uses the following command:
                                          $tshark -r file.pcap -Y "http or udp"
                                          Which of the following will the command line display?

                                          Answer: C

                                          Explanation:
                                          The -r file.pcap argument instructs TShark to read packets from the specified capture file, while -Y applies a Wireshark display filter . The expression "http or udp" therefore displays packets recognized as HTTP or packets using UDP.
                                          Traditional HTTP traffic is unencrypted and can be dissected directly as HTTP. HTTPS normally carries HTTP inside TLS encryption and therefore is not displayed merely because the filter specifies http. DNS commonly operates over UDP, particularly for standard queries and responses, so ordinary DNS traffic satisfies the udp portion of the expression. Consequently, B is the best answer in the context of the available choices.
                                          A technical distinction is important: the expression does not mean "HTTP or DNS specifically." The udp portion matches UDP traffic generally, which can include protocols other than DNS. Nevertheless, within the examination scenario, the intended comparison is plaintext HTTP versus encrypted HTTPS together with standard UDP-based DNS.
                                          Wireshark's documentation distinguishes display filters from capture filters, and TShark is the command-line network traffic analyzer within the Wireshark suite. CS0-004 places packet-analysis capabilities within Security Operations.

                                          NEW QUESTION # 44
                                          Given the following report:

                                          Which of the following vulnerabilities should be prioritized for immediate remediation?

                                          Answer: C

                                          Explanation:
                                          The SQL injection vulnerability should be remediated first because it affects a critical financial processing module, is exploitable over the network, requires no privileges, requires no user interaction, and has a known exploit available. Although the remote code execution vulnerability has a slightly higher CVSS score, it requires privileges and user interaction and does not have a known exploit available. Considering exploitability, business context, and asset criticality, the SQL injection vulnerability presents the highest immediate risk.


                                          NEW QUESTION # 45
                                          Which of the following best describes the reason a root cause analysis is an important part of the incident response process?

                                          Answer: A

                                          Explanation:
                                          Root cause analysis identifies the underlying systemic issues that allowed the incident to occur, enabling leadership to address weaknesses across processes, technology, or teams and allocate resources effectively to prevent recurrence.


                                          NEW QUESTION # 46
                                          Users frequently get disconnected from the company's internal wireless network. The wireless system and clients are healthy. Once disconnected, the wireless clients reconnect automatically.
                                          Which of the following is the best way for a security analyst to determine the source of the wireless disconnection?

                                          Answer: C

                                          Explanation:
                                          Deauthentication attacks force wireless clients to disconnect from an access point by sending forged deauthentication frames. Since the clients automatically reconnect and the wireless infrastructure appears healthy, analyzing the wireless airspace with Kismet is the best way to detect unauthorized deauthentication frames and determine whether a wireless attack is causing the disconnects.


                                          NEW QUESTION # 47
                                          Due to some incidents involving non-authorized devices, a company wants to implement a solution that only allows access to its LAN and Wi-Fi if certain policies are matched. Which of the following is the best solution to implement?

                                          Answer: D

                                          Explanation:
                                          Network Access Control (NAC) enforces security policies before allowing devices to connect to wired or wireless networks. It can verify device compliance, authentication status, and other security requirements, ensuring that only authorized and compliant devices are granted access to the LAN and Wi-Fi network.
