350-701 Network Security Practice Question
An engineer wants to configure high availability on a pair of Cisco Firepower Threat Defense (FTD) devices. Which HA mode supports active/standby failover with stateful replication of connection information?
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
✓
Active/standby with stateful failover
Active/standby HA with stateful failover syncs connection states. Active/active is typically for routed mode with asymmetric routing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Active/standby with stateful failover
Why this is correct
Correct. Active/standby replicates connection tables to the standby unit.
- ✗
Active/standby without stateful failover
Why it's wrong here
Stateless failover drops connections; stateful is needed to preserve them.
- ✗
Active/active with asymmetric routing
Why it's wrong here
Active/active does not provide stateful failover for all connections.
- ✗
Clustering
Why it's wrong here
Clustering is different and not typical for FTD HA.

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 |
