Which Layer of the OSI Model is responsible for routing?

  1. Network
  2. Transport
  3. Session
  4. Data link

Answer(s): A

Explanation:

Routing decisions are made at the Network Layer (Layer 3) of the OSI model. This layer is responsible for determining the best path for data packets to travel from the source to the destination across multiple networks. Protocols like IP (Internet Protocol) operate at this layer, handling addressing and routing functions essential for network communication.



Which is the correct "fw monitor" syntax for creating a capture file for loading it into Wireshark?

  1. fw monitor -e "accept <FILTER EXPRESSION*;" > Output.cap
  2. This cannot be accomplished as it is not supported with R80.10
  3. fw monitor -e "accept <FILTER EXPRESSION^" -o Output.cap
  4. fw monitor -e "accept <FILTER EXPRESSION*;" -file Output.cap

Answer(s): D

Explanation:

The correct syntax for using fw monitor to create a capture file compatible with Wireshark involves specifying the filter expression and the output file with the .cap extension. Option D correctly uses the -e flag for the filter expression and the -file flag to specify the output file, ensuring the captured data can be seamlessly imported into Wireshark for analysis.



What is the most efficient way to view large fw monitor captures and run filters on the file?

  1. snoop
  2. CLI
  3. CLISH
  4. Wireshark

Answer(s): D

Explanation:

Wireshark is the most efficient tool for viewing large fw monitor capture files. It provides powerful filtering capabilities, a user-friendly interface, and detailed packet analysis features that make handling large datasets manageable.
While CLI tools like snoop and fw monitor offer basic packet viewing, they lack the advanced filtering and visualization options that Wireshark provides.



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

  1. fw monitor
  2. Wait for out of business hours to do a packet capture
  3. cppcap
  4. You need to use tcpdump with -e option to decrease the length of packet in captures and it will utilize the less CPU

Answer(s): C

Explanation:

When tcpdump causes high CPU usage, an alternative is to use cppcap, which is optimized for capturing packets with lower CPU overhead in Check Point environments. cppcap is designed to work efficiently with Check Point's infrastructure, reducing the performance impact compared to generic tools like tcpdump.
