300-710 SNCF Deployment Practice Question
An administrator is configuring Equal-Cost Multi-Path (ECMP) routing on a Cisco Secure Firewall Threat Defense deployment to balance traffic across two upstream next-hop routers. How does the firewall select the specific path for a given TCP flow?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A hashing algorithm based on the flow's 5-tuple to maintain session consistency.
ECMP on Cisco Secure Firewall uses a hashing algorithm based on the 5-tuple (source IP, destination IP, source port, destination port, and protocol) to ensure packets belonging to the same flow take the same path.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A hashing algorithm based on the flow's 5-tuple to maintain session consistency.
Why this is correct
Flow-based ECMP hashing uses the 5-tuple to keep all packets of a single session traversing the same next-hop router.
- ✗
Strict priority-based path selection where the primary route is exhausted before secondary routing begins.
Why it's wrong here
Priority-based selection describes floating static routes or backup paths, not Equal-Cost Multi-Path.
- ✗
Dynamic bandwidth utilization monitoring where packets are instantly dynamically switched to the lowest latency link.
Why it's wrong here
ECMP relies on static routing table hashing, not real-time per-packet latency switching.
- ✗
Round-robin packet scheduling across all available paths for every individual packet.
Why it's wrong here
Round-robin per packet would cause severe out-of-order packet delivery, breaking TCP sessions.
