Cisco ENCOR Wireless and Automation 1 — Questions and Answers
Question 1: Which wireless architecture mode has the WLC handle all real-time traffic forwarding?
- Autonomous mode
- Local mode (centralized) (Correct answer)
- FlexConnect mode
- Monitor mode
Correct answer: Local mode (centralized)
In local (centralized) mode, all AP traffic is tunneled via CAPWAP to the WLC, which forwards it to the wired network.
Question 2: What protocol do Cisco lightweight APs use to communicate with the WLC?
- LWAPP
- CAPWAP (Correct answer)
- GRE
- MPLS
Correct answer: CAPWAP
Control and Provisioning of Wireless Access Points (CAPWAP) is the current standard protocol used between Cisco APs and WLCs.
Question 3: Which Python library is the standard for making HTTP REST API calls in Python automation scripts?
- paramiko
- netmiko
- requests (Correct answer)
- ncclient
Correct answer: requests
The 'requests' library is the de facto standard Python library for making HTTP/HTTPS REST API calls.
Question 4: What is the role of YANG in network automation?
- A transport protocol for configuration data
- A data modeling language used to define the structure of network configuration and state data (Correct answer)
- An encoding format like JSON or XML
- A Python library for network automation
Correct answer: A data modeling language used to define the structure of network configuration and state data
YANG (RFC 6020/7950) is a data modeling language used to define the data hierarchy and constraints for NETCONF/RESTCONF operations.
Question 5: Which wireless security protocol replaced WPA2 and introduced Simultaneous Authentication of Equals (SAE)?
- WPA
- WPA2-Enterprise
- WPA3 (Correct answer)
- 802.11i
Correct answer: WPA3
WPA3 introduced SAE (Dragonfly handshake) to replace PSK, providing forward secrecy and resistance to offline dictionary attacks.
Question 6: In wireless networks, what does the term 'roaming' refer to?
- Changing SSID names
- A client moving between APs while maintaining its network session (Correct answer)
- Scanning for hidden SSIDs
- Switching between 2.4 GHz and 5 GHz bands
Correct answer: A client moving between APs while maintaining its network session
Roaming is the process by which a wireless client seamlessly transfers its association from one AP to another while maintaining active sessions.
