JNCIA-SEC Monitoring And Troubleshooting Practice Question
An administrator is analyzing the active session table using the 'show security flow session' command to diagnose asymmetric routing. Which TWO pieces of information are displayed in the session table output that help identify this issue? (Choose two)
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
✓
Packet and byte counters incrementing for both the client-to-server and server-to-client directions.
Session tables display reverse and forward flow paths, interface names, and packet/byte counters which highlight asymmetric routing paths.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The exact CPU core processing the session flow.
Why it's wrong here
Session table output does not display specific CPU core assignments for individual sessions.
- ✓
Packet and byte counters incrementing for both the client-to-server and server-to-client directions.
Why this is correct
Viewing counters for both directions helps verify if return traffic is reaching the expected interface.
- ✗
The complete BGP path attribute list for the session route.
Why it's wrong here
BGP attributes are maintained in the routing table (inet.0), not the security session table.
- ✓
Incoming and outgoing interface names for both forward and reverse traffic directions.
Why this is correct
Interface details show if traffic enters and exits unexpected interfaces, indicating asymmetric routing.
- ✗
The administrative distance of the route used to establish the session.
Why it's wrong here
Administrative distance is a routing protocol metric found in routing tables, not session tables.

Asymmetric Encryption Algorithm Comparison
| Algorithm | Key Exchange | Signatures | Equivalent Security Key | Notes |
|---|---|---|---|---|
| RSA-3072 | Yes | Yes | 128-bit | Widely deployed; slow for bulk data |
| ECDSA P-256 | No | Yes | 128-bit | Fast signatures; standard TLS certs |
| ECDH / ECDHE | Yes | No | 128-bit | Perfect forward secrecy in TLS 1.3 |
| DH / DHE | Yes | No | 128-bit (3072-bit key) | Replaced by ECDHE in modern TLS |
| Ed25519 | No | Yes | ~128-bit | SSH keys, modern PKI |
