Demo Questions
Question 1
Which option must be used to support a WLC with an IPv6 management address and 100 Cisco Aironet 2800 Series access points that will use DHCP to register?
- 43
- 52
- 60
- 82
Correct answer: B
Explanation:
The CAPWAP protocol allows a lightweight access point (AP) to use DHCP to discover a wireless controller to which it is connected to. Cisco lightweight APs running 8.0 and above support DHCP discovery for both IPv4 and IPv6 networks:IPv4 Cisco lightweight APs implement DHCP option 43 to supply the IPv4 management interface addresses of the primary, secondary, and tertiary wireless controllers (see the guide).IPv6 Cisco lightweight APs implement DHCPv6 option 52 (RFC 5417) to supply the IPv6 management interface addresses of the primary, secondary, and tertiary wireless controllers.Reference: https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-0/IPV6_DG.htmlThis question asks about DHCPv6, not DHCPv4 so Option 52 is the best answer.

Question 2
Drag and drop the characteristics from the left onto the switching mechanisms they describe on the right.
Correct answer: To work with this question, an Exam Simulator is required.
Explanation:
There are different switching methods to forward IP packets. Here are the different switching options:Process switching:All packets are examined by the CPU and all forwarding decisions are made in software...very slow!Fast switching (also known as route caching):The first packet in a flow is examined by the CPU; the forwarding decision is cached in hardware for the next packets in the same flow. This is a faster method.(CEF) Cisco Express Forwarding (also known as topology based switching):Forwarding table created in hardware beforehand. All packets will be switched using hardware. This is the fastest method but there are some limitations. Multilayer switches and routers use CEF. There are different switching methods to forward IP packets.

Question 3
An engineer must create a script to append and modify device entries in a JSON-formatted file. The script must work as follows:
Until interrupted from the keyboard, the script reads in the hostname of a device, its management IP address, operating system type, and CLI remote access protocol.
After being interrupted, the script displays the entered entries and adds them to the JSON-formatted file, replacing existing entries whose hostname matches.
The contents of the JSON-formatted file are as follows:
Drag and drop the statements onto the blanks within the code to complete the script. Not all options are used.

Explanation:
We tested this code successfully: And this is the result: Note:In Python, "pass" is a null statement. It is usually used as a placeholder.In order to run the code successfully, we must have the "devicesData.json" first with at least one sample.This code runs infinitely with "while True:" so we have to use Keyboard interrupt to exit (Ctrl-C in Windows, for example).
