 148.  D.  The Wi-Fi Protected Access 2 (WPA2) protocol can be configured with Advanced 

Encryption Standard (AES) encryption to provide the highest level of security. Wi-Fi 

Protected Access (WPA) cannot be configured with AES encryption; therefore, this is a 

wrong answer. WPA2 cannot be configured with Temporal Key Integrity Protocol (TKIP); 

only WPA uses the RC4 encryption algorithm and TKIP.

 149.  In order to satisfy the requirements of the client, WPA2-Personal should be configured 

for the wireless network. WPA2-Personal will allow for 128-bit AES-CCMP encryption 

and work with a pre-shared key (PSK) to minimize infrastructure. WPA-Enterprise and 

WPA3-Enterprise require certificate services and an AAA server. WPA-Personal is weaker 

encryption than WPA2-Personal.

 150.  B.  When a WLAN is configured with WPA-TKIP, it will not be able to achieve over 54 

Mbps. The Counter Mode with Cipher Block Chaining Message Authentication Code 

Protocol (CCMP) is based on of the Advanced Encryption Standard (AES) encryption 

protocol and will not hinder throughput. Configuring a pre-shared key (PSK) will also not 

hinder throughput.

Chapter 6: Automation and 

Programmability (Domain 6)

 1.  B.  A reason to automate a process for the configuration of several routers is to create 

a positive outcome that can be reproduced. Automating processes for configuration 

decreases the possibility for misconfiguration. Automation of configuration does not 

decrease problems from the new configuration; if anything, it automates the increase of 

possible problems. Although it might seem like automating a process for configuration 

allows you to do less work, it is not always the case.

 2.  C.  Creating a Python script to configure each router is the best way to complete this task. 

You can automate the process and save time since the entry of the route is a repetitious 

process. Copying and pasting scripts from Notepad++ or Excel into each router will 

require you to log into each router. Doing this increases the chances of missing a router. 

You could also work with a partner and start at different ends of the list, but again, this 

approach introduces the possibility of errors and ties up two technicians.

 3.  C.  The number one motivating factor to use network automation is to reduce the human 

error factor when creating bulk changes. Network automation will not reduce the number 

of changes to be made. As an example, an updated ACL on all the routers will still need to 

be updated on all the routers. Network automation also does not reduce the complications 

that arise from changes; it actually increases them. Network automation also increases the 

planning time for changes. A network automation script can change everything rapidly; if 

it’s wrong, it can even lead to an outage of services.
