Ccna certification Practice Tests

 95.  B.  The fabric of a software-defined network switches packets on layer 3. All of the other 

options are incorrect.

 96.  A.  You can configure the upgrade of IOS for network devices from the Provision section 

of the Cisco DNA Center. The Design section allows you to create a hierarchical design of 

the network, with a graphical map. The Policy section allows you to create policies based 

upon applications, traffic, and IP-based access control lists (ACLs), just to name a few. 

The Assurance section of the Cisco DNA Center allows you to see the overall health of 

network devices managed by DNA Center.

 97.  C.  When a status code of 401 is returned, it means that the method was unauthorized. A 

status code of 200 or 202 means the method was okay or accepted; these are the two most 

common.

 98.  D.  Ansible uses a configuration file and can be programmed with Python. Desired State 

Configuration (DSC) is a Microsoft-centric product that is programmed in PowerShell. 

Chef uses Domain Specific Language (DSL) with Ruby. Puppet uses DSL with the 

PuppetDSL language.

 99.  B.  A requirement for using Ansible for configuration management is root Secure Shell 

(SSH) access to the remote system. Internet access is only required if you are managing a 

system across the Internet. An unrestricted firewall is not required because you only need 

port 22 TCP (SSH) for Ansible to access the remote machine. Ansible is scripted with 

Python and not Ruby.

 100.  A.  The command 

show interface status | json-pretty native is used to 

convert the output of a command to JSON in a Cisco router or switch. You will enter 

the command first, such as 

show interface status, and then pipe the output to the | 

json-pretty command and specify native formatting. The command json interface 

status is incorrect. The command show interface status | json is incorrect. The 

command 

show interface status json is incorrect.

 1.  C.  A router will stop broadcasts by default. If you add a router to a flat network, which 

is a single broadcast domain, you effectively raise bandwidth by reducing the number 

of broadcasts. A firewall is a network device that can protect a network from malicious 

traffic and/or restrict access. A hub is nothing more than a multiport repeater and does not 

create broadcast domains. A switch is a layer 2 device that creates micro-segmentation.
