NEW QUESTION # 98
An engineer is addressing a connectivity issue between two servers where the remote server is unable to establish a successful session. Initial checks show that the remote server is not receiving an SYN-ACK while establishing a session by sending the first SYN. What is causing this issue?
- A. incorrect snaplen configuration
- B. incorrect TCP handshake
- C. incorrect OSI configuration
- D. incorrect UDP handshake
Answer: B
Explanation:
A TCP handshake is a three-way exchange of messages between a client and a server to establish a TCP connection. The client initiates the handshake by sending a SYN packet with a sequence number to the server. The server responds with a SYN-ACK packet with its own sequence number and an acknowledgment number that is the client's sequence number plus one. The client completes the handshake by sending an ACK packet with an acknowledgment number that is the server's sequence number plus one. If the remote server is not receiving an SYN-ACK packet from the local server, it means that the TCP handshake is not completed and the connection is not established. This could be caused by various factors, such as network congestion, firewall rules, packet filtering, or misconfiguration of the TCP parameters on either end.

NEW QUESTION # 103
An engineer is working on a ticket for an incident from the incident management team A week ago. an external web application was targeted by a DDoS attack Server resources were exhausted and after two hours it crashed. An engineer was able to identify the attacker and technique used Three hours after the attack, the server was restored and the engineer recommended implementing mitigation by Blackhole filtering and transferred the incident ticket back to the IR team According to NIST SP800-61, at which phase of the incident response did the engineer finish work?
- A. post-incident activity
- B. preparation
- C. containment eradication and recovery
- D. detection and analysis
Answer: C
Explanation:
According to NIST SP800-61, the incident response phase called "Containment, Eradication, and Recovery" involves containing the incident, eradicating the threat, and recovering from the incident2. In the scenario described, the engineer worked on containing the DDoS attack by identifying the attacker and the technique used, which is part of the containment process. The recommendation to implement Blackhole filtering is part of the eradication process, where measures are taken to prevent the attack from happening again. Finally, restoring the server is part of the recovery process, where normal operations are resumed. Therefore, the engineer finished work during the "Containment, Eradication, and Recovery" phase.

- D. src=10.11.0.0/16 and dst=10.11.0.0/16
Answer: A
Explanation:
In Wireshark, to filter traffic for a specific LAN, the correct syntax uses ip.src== and ip.dst== to specify the source and destination IP addresses. The /16 denotes the subnet mask, indicating that we are interested in the entire 10.11.x.x range. This filter will show all traffic where both the source and destination IP addresses fall within the specified LAN, excluding any internet traffic. References: The information is based on the Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) course, which covers network intrusion analysis and the use of tools like Wireshark for traffic analysis1.
