   A security analyst is monitoring network traffic and sees a large number of TCP SYN packets sent to a single internal server from many different external IP addresses. The SYN packets are not followed by SYN-ACK responses from the server. The analyst also notices that the server's CPU usage is high. What is the most likely attack?

   • AA DNS amplification attack.
   • BA port scan, where the attacker is probing for open ports.
   • CA SYN flood attack, where the attacker sends many SYN packets to exhaust the server's resources.
   • DA man-in-the-middle attack.

   A network administrator is monitoring a link that carries VoIP traffic. The administrator notices that the average latency is 50 ms, jitter is 30 ms, and packet loss is 1%. Users report choppy voice calls. What is the most likely cause?

   • AThe link is saturated with data traffic.
   • BThe latency of 50 ms is too high for VoIP.
   • CThe packet loss of 1% is causing the choppy calls.
   • DThe jitter is too high for VoIP, causing packets to arrive unevenly.
