Which encoding is used to protect a username and login with RESTful API basic authentication?
Answer: A
RESTful API Basic Authentication uses Base64 encoding to convert the username and password into formats, but this does not encrypt the data. It is usually used in conjunction with HTTPS (SSL/TLS) to ensure the security of data transmission.

SIMULATION - Guidelines - This is a lab item in which tasks will be performed on virtual devices. • Refer to the Tasks tab to view the tasks for this lab item. • Refer to the Topology tab to access the device console(s) and perform the tasks. • Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window. • All necessary preconfigurations have been applied. • Do not change the enable password or hostname for any device. • Save your configurations to NVRAM before moving to the next item. • Click Next at the bottom of the screen to submit this lab and move to the next question. • When Next is clicked, the lab closes and cannot be reopened. Topology -
Tasks - OSPF is preconfigured on all devices except R20. Configure R20 to complete these tasks. Task 1: Configure OSPF according to the topology using these requirements: • Use Process ID 20. • Use Loopback0 for the Router ID. • Advertise all networks into OSPF. o Do not use network statements under the OSPF process to accomplish this task. Task 2: Configure a /18 summary route for Area 40. • Advertise only Type 3 LSAs into Area 0. R20 -
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
Task 1: R20# configure terminal R20(config)# interface ethernet 0/0 R20(config-if)# ip ospf 20 area 0 R20(config)# interface ethernet 0/1 R20(config-if)# ip ospf 20 area 0 R20(config)# interface ethernet 0/2 R20(config-if)# ip ospf 20 area 40 Task 2: R20# configure terminal R20(config)# router ospf 20 R20(config-router)# area 40 range 10.40.0.0 255.255.192.0 R20(config-router)# area 40 stub add command 'area 40 stub', for 'TYPE 3 LSAs only' of task 2.

Which antenna type should be used for a site-to-site wireless connection?
Answer: D
Correct answer is patch antenna. Patch anttena have more gain and more directional radiation pattern. Check Cisco Aironet 14-dBi Patch Antenna (AIR-ANT5114P-N): https://www.cisco.com/c/en/us/td/docs/wireless/antenna/installation/guide/ant5114P.html vs Cisco WPAN Yagi Antenna (ANT-WPAN-Y-OUT-N) https://www.cisco.com/c/en/us/td/docs/routers/connectedgrid/antennas/installing-combined/b-cisco-industrial-routers-and-industrial-wireless-access-points-antenna-guide/m-ant-wpan-y-out-n.html

Refer to the exhibit. What is the result of this Python code?
Answer: A
The result of the Python code >>> (3 * 5) % 2 is calculated as follows: Multiplication: ( 3 \times 5 = 15 ) Modulo Operation: ( 15 \mod 2 ) The modulo operation finds the remainder when 15 is divided by 2. Since 15 divided by 2 is 7 with a remainder of 1, the result is: [ 15 \mod 2 = 1 ] So, the result is 1.
