Exam-day tips

Know SRX first-path vs fast-path packet processing and where NAT and policy lookups occur.
Policy matching is top-down, first match; know where the default deny applies.
Be clear on the order of source NAT, destination NAT and static NAT relative to security policy.
Practice show security flow session output; questions often ask you to interpret it.
Juniper does not publish the passing score or objective weights, so cover every listed objective rather than gambling on a few.
