   Which two encoding methods are supported by REST APIs? (Choose two.)

   • ASGML
   • BYAML
   • CXML
   • DJSON
   • EEBCDIC

   Show answer

   Answer: CD

   Explanation

   The Application Policy Infrastructure Controller (APIC) REST API is a programmatic interface that uses REST architecture. The API accepts and returns HTTP (not enabled by default) or HTTPS messages that contain JavaScript Object Notation (JSON) or Extensible Markup Language (XML) documents. Reference: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/2-x/rest_cfg/2_1_x/b_Cisco_APIC_REST_API_Configuration_Guide/ b_Cisco_APIC_REST_API_Configuration_Guide_chapter_01.html

   What are two characteristics of a controller-based network? (Choose two.)

   • AIt uses Telnet to report system issues.
   • BThe administrator can make configuration updates from the CLI.
   • CIt uses northbound and southbound APIs to communicate between architectural layers.
   • DIt decentralizes the control plane, which allows each device to make its own forwarding decisions.
   • EIt moves the control plane to a central point.

   Answer: CE

   Explanation

   controller-based networking A style of building computer networks that use a controller that centralizes some features and provides application programming interfaces (APIs) that allow for software interactions between applications and the controller (northbound APIs) and between the controller and the network devices (southbound APIs). centralized control plane An approach to architecting network protocols and products that places the control plane functions into a centralized function rather than distributing the function across the networking devices.

   Answer:

   Explanation

   JSON data is written as name/value pairs. A name/value pair consists of a field name (in double quotes), followed by a colon, followed by a value: ג€nameג€:ג€Markג€ JSON can use arrays. Array values must be of type string, number, object, array, boolean or null. For example: { ג€nameג€:ג€Johnג€, ג€ageג€:30, ג€carsג€:[ ג€Fordג€, ג€BMWג€, ג€Fiatג€ ] } JSON can have empty object like ג€taskIdג€:{}

   Explanation

   The focus of Ansible is to be streamlined and fast, and to require no node agent installation. Thus, Ansible performs all functions over SSH. Ansible is built on Python, in contrast to the Ruby foundation of Puppet and Chef. TCP port 10002 is the command port. It may be configured in the Chef Push Jobs configuration file . This port allows Chef Push Jobs clients to communicate with the Chef Push Jobs server. Puppet is an open-source configuration management solution, which is built with Ruby and offers custom Domain Specific Language (DSL) and Embedded Ruby (ERB) templates to create custom Puppet language files, offering a declarative-paradigm programming approach. A Puppet piece of code is called a manifest, and is a file with .pp extension.

5. Question 1035 · 1334 in bank

   Select 2

   Which two capabilities of Cisco DNA Center make it more extensible as compared to traditional campus device management? (Choose two.)

   • AREST APIs that allow for external applications to interact natively
   • Badapters that support all families of Cisco IOS software
   • CSDKs that support interaction with third-party network equipment
   • Dmodular design that is upgradable as needed
   • Ecustomized versions for small, medium, and large enterprises

   Show answer

   Answer: AC

   Explanation

   SDN=Software-Defined Networking. Its in the name "software." API's= Application Programming Interface. = software REST API's = isn't a specific API but a set of rules for API's SDKs= Software Development Kits Enabling software to allow for external applications defiantly makes it more "extensible" (able to be extended). The traditional device management seemed to really want to keep things proprietary, or at least attempt a push in that direction. It appears now that Cisco knows it needs to adapt and allow for 3rd party devices/applications so that it can remain competitive.

7. Question 1037 · 1334 in bank

   What software-defined architecture plane assists network devices with making packet-forwarding decisions by providing Layer 2 reachability and Layer 3 routing information?

   • Amanagement plane
   • Bcontrol plane
   • Cdata plane
   • Dpolicy plane

   Show answer

   Answer: B

   Explanation

   The control plane is the part of a network that controls how data is forwarded, while the data plane controls the actual forwarding process. Making packet forwarding decisions is ‘how data is forwarded’. ANSWER = B

8. Question 1038 · 1334 in bank

   Select 2

   What are two benefits of controller-based networking compared to traditional networking? (Choose two.)

   • Acontroller-based increases network bandwidth usage, while traditional lightens the load on the network
   • Bcontroller-based reduces network configuration complexity, while traditional increases the potential for errors
   • Ccontroller-based allows for fewer network failures, while traditional increases failure rates
   • Dcontroller-based provides centralization of key IT functions, while traditional requires distributed management functions
   • Econtroller-based inflates software costs, while traditional decreases individual licensing costs

   Show answer

   Answer: BD

   Explanation

   C. controller-based allows for fewer network failures, while traditional increases failure rates D. controller-based provides centralization of key IT functions, while traditional requires distributed management functions Regarding the controller-based network, A and E are not benefits. I don't know if C is true, but B and D are. So B and D

9. Question 1039 · 1334 in bank

   Which type of API allows SDN controllers to dynamically make changes to the network?

   • Anorthbound API
   • BREST API
   • CSOAP API
   • Dsouthbound API

   Show answer

   Answer: D

   Explanation

   Answer is D Cisco overview doc for SDN here: https://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Data_Center/VMDC/SDN/SDN.html however I recommend everyone to spend 40 mins watching any of the (non-vendor specific) fundamentals of SDN/Openflow vids on YT...my personal rec is David Mahler's stuff (fact is nowadays if you don't know some SDN basics you just won't be getting jobs anymore!!)
