   Refer to the exhibit. A network engineer must be notified when a user switches to configuration mode. Which script should be applied to receive an SNMP trap and a critical-level log message?

   • Aaction 1.0 snmp-trap strdata “Configuration change alarm” action 1.0 syslog priority critical msg “Configuration change alarm”
   • Baction 1.0 snmp-trap strdata “Configuration change alarm” action 2.0 syslog msg “Configuration change alarm”
   • Caction 1.0 snmp-trap strdata “Configuration change alarm” action 1.1 syslog priority critical msg “Configuration change alarm”
   • Daction 1.0 snmp-trap strdata “Configuration change critical alarm”

   Show answer

   Answer: C

   Explanation

   o configure an event manager applet that notifies a network engineer when a user enters configuration mode, and sends both an SNMP trap and a critical-level log message, the correct script should include both actions properly sequenced. Correct Answer: C action 1.0 snmp-trap strdata “configuration change alarm” action 1.1 syslog priority critical msg “configuration change alarm” Explanation: action 1.0 snmp-trap strdata “configuration change alarm”: This line sends an SNMP trap with a message indicating a configuration change. action 1.1 syslog priority critical msg “configuration change alarm”: This line logs a critical message to the syslog indicating the same configuration change.

   In a wireless network environment, what is calculated using the numerical values of the transmitter power level, cable loss, and antenna gain?

   • ASNR
   • BRSSI
   • CEIRP
   • DdBi

   Show answer

   Answer: C

   Explanation

   Effective Isotropic Radiated Power The radiated (transmitted) power is rated in either dBm or W. Power that comes off an antenna is measured as effective isotropic radiated power (EIRP). EIRP is the value that regulatory agencies, such as the FCC or European Telecommunications Standards Institute (ETSI), use to determine and measure power limits in applications such as 2.4-GHz or 5-GHz wireless equipment. In order to calculate EIRP, add the transmitter power (in dBm) to the antenna gain (in dBi) and subtract any cable losses (in dB).

6. Question 56 · 1003 in bank

   Which method requires a client to authenticate and has the capability to function without encryption?

   • AWEP
   • BPSK
   • Copen
   • DWebAuth

   Show answer

   Answer: D

   Explanation

   WebAuth is used for authentication, not encryption. A pre-shared key (PSK) is used in conjunction with WebAuth to provide encryption capabilities. https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wlan-security/115951-web-auth-wlc-guide-00.html#:~:text=Although%20the%20combination,method%20without%20encryption.

7. Question 57 · 1003 in bank

   An engineer must update the local web authentication details on a Cisco 5520 WLC. The engineer has one active SSID configured for web authentication and plans to update the virtual interface with a nonroutable IP address. Which command must the engineer apply?

   • Aconfig wlan create wlan_idname
   • Bconfig interface address virtual 1.1.1.1
   • Cconfig interface address dynamic-interface virtual 192.0.2.1
   • Dconfig interface address virtual 192.0.2.1

   Show answer

   Answer: D

   Explanation

   From ChatGPT: To update the local web authentication details on a Cisco 5520 Wireless LAN Controller (WLC) and configure the virtual interface with a non-routable IP address, the engineer should use the following command in the WLC CLI: config interface address virtual For example, if the engineer wants to set the virtual interface IP address to a non-routable IP like 192.0.2.1, the command would be: config interface address virtual 192.0.2.1 This virtual interface is used for web authentication redirection.

   Refer to the exhibit. What is achieved when this Python script is executed?

   • AAll devices that are looped through in the devices.txt file are put into a list that is appended to the parent dictionary.
   • BAll devices that are looped through in the devices.txt file are put into a single dictionary that is appended to the parent list.
   • CEach device that is looped through in the devices.txt file is put into its own list that is appended to the parent dictionary.
   • DEach device that is looped through in the devices.txt file is put into its own dictionary that is appended to the parent list.

   Show answer

   Answer: D

   Explanation

   Explained by Claude AI: 1. The script expects a text file called 'devices.txt' that contains device information in a comma-separated format. 2. The script then reads through the file line by line: for line in file: device_info_list = line.strip().split(',') # Removes whitespace and splits by commas device_info = {} # Creates an empty dictionary for each device 3. For each line, the script creates a dictionary to store the device's information in a more organized way. The strip() method removes any extra whitespace or newline characters, and split(',') breaks the line into a list using commas as separators. 4. The script then assigns each piece of information to specific keys in the dictionary. 5. After creating the dictionary for a device, it's added to the main list. 6. Finally, the script prints the entire list of devices and closes the file.

Topology -

    

    Tasks - The operations team started configuring network devices for a new site. Complete the configurations to achieve these goals: 1. Configure Rapid PVST+ on SW20. 2. The trunk between SW20 and SW30 is not operational. Troubleshoot the issue and ensure PC3 can ping PC1 (10.10.100.10) across the link. 3. The LACP port channel between SW10 and SW20 is not operational. Troubleshoot the issue and ensure PC3 can ping PC2 (10.10.100.20) across the port channel. Note: No access is provided to SW10 or SW30. Resolve these issues by making changes only to SW20. Traffic on all trunks should be restricted to only active VLANs.
