Quick Answer
The correct order for NETCONF subscription steps is: establish a NETCONF session, subscribe to YANG data, receive periodic updates, and finally send <close-session> to unsubscribe. This sequence follows the logical lifecycle of a NETCONF monitoring session, where you must first open a secure transport and hello-exchange to create the session, then issue a subscription request for specific YANG data streams, after which the device pushes periodic updates until you explicitly terminate the subscription with a close-session RPC. On the ENCOR 350-401 exam, this drag-and-drop question tests your understanding of NETCONF’s event-driven telemetry model, often tripping candidates who mistakenly place the close-session step before receiving updates or who forget that unsubscription is an explicit action, not automatic. A common trap is confusing the subscription order with the initial NETCONF capability exchange; remember that you cannot unsubscribe from something you haven’t yet subscribed to. For a quick memory aid, think “Open, Subscribe, Receive, Close” — like a conversation where you knock, ask for news, listen, then say goodbye.

Correct answer & explanation

Establish NETCONF over SSH session
First establish NETCONF session, then subscribe to YANG data, then receive periodic updates, and finally unsubscribe.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 350-401 NAT questions on configuration and troubleshooting.
