• Question 143:

  Which statement is correct about capturing transit packets on an SRX Series Firewall?

  A. You can capture transit packets on the egress interface using a firewall filter.
  B. You can capture transit packets by using a firewall filter on the loopback interface.
  C. You can capture transit packets by using the tcpdump utility in the shell.
  D. You can capture transit packets using sampling and port mirroring.
  D. You can capture transit packets using sampling and port mirroring.

  Transit traffic is defined as traffic that passesthroughthe SRX (not destined to the Routing Engine). To capture transit traffic:

  Sampling and port mirroring (Option D)are the correct supported methods for capturing or exporting transit traffic. Sampling allows captured packets to be sent to a file or collector, while port mirroring sends a copy to a monitoring interface.

  Option A:Firewall filters on an egress interface cannot directly capture packets; they can only count, accept, discard, or sample. Sampling itself is separate.

  Option B:Loopback interface (lo0) is for control-plane traffic, not transit traffic.

  Option C:tcpdump is not supported on SRX as a tool for capturing transit packets; the operational command monitor traffic interface is used, but sampling/port mirroring is the recommended scalable approach.

  Correct Method:Sampling and port mirroring
