Running tcpdump causes a significant increase on CPU usage, what other option should you use?

Show Suggested Answer Hide Answer
Suggested Answer: A

Yes, it is possible to analyze ICMP packets with tcpdump. While tcpdump is often associated with capturing TCP packets, it is not limited to them and can capture and analyze any protocol that traverses the network, including ICMP, which operates at Layer 3 (Network Layer) of the OSI model. ICMP packets do not use ports, but tcpdump can filter and display these packets based on other criteria such as type and code fields.

If I wanted to increase CPU usage, I'd just run a cryptocurrency miner in the background. At least I'd get some digital coins out of it.

I think the -e option in tcpdump is the way to go. It's like using a scalpel instead of a sledgehammer to get the job done.

Waiting for out of business hours to do a packet capture? That's like waiting for a meteor to hit the earth to get a chance to observe it. Not very practical.

Wait, there's a tool called cppcap? I've never heard of that before. Sounds like it could be an interesting alternative to tcpdump.

Option D seems like the way to go. Reducing the packet capture length is a smart way to optimize CPU usage without sacrificing the capture data.
