A security analyst wants to capture large amounts of network data that will be analyzed at a later time. The packet capture does not need to be in a format that is readable by humans, since it will be put into a binary file called "packetCapture." The capture must be as efficient as possible, and the analyst wants to minimize the likelihood that packets will be missed.
Which of the following commands will best accomplish the analyst’s objectives?
- A . tcpdump -w packetCapture
- B . tcpdump -a packetCapture
- C . tcpdump -n packetCapture
- D . nmap -v > packetCapture
- E . nmap -oA > packetCapture
