CCNA – Automation EXAM WITH
CORRECT ANSWERS
What is the Data Plane responsible for? - CORRECT ANSWERS ✔✔All the various
parts of forwarding traffic, including reception, processing, and forwarding. It is
sometimes called the Forwarding Plane.
Name 5 functions that happen on the data plane. - CORRECT ANSWERS ✔✔1)
Encrypting traffic. 2) Network address translation. 3) ACL traffic filtering. 4) Data
encapsulation and decapsulation. 5) Adding or removing 802.1Q headers.
What happens at the Control Plane? - CORRECT ANSWERS ✔✔Decision making
that helps devices know where to forward traffic.
Name 5 functions that happen on the control plane. - CORRECT ANSWERS ✔✔1)
Routing protocols. 2) STP. 3) IPv4 ARP. 4) IPv6 Neighbor discovery. 5) Switches
learning MAC addresses.
What happens on the Management Plane? - CORRECT ANSWERS ✔✔Everything to
do with device management, including Telnet, SSH, and automation ports that are
used for automated management of devices.
How is the control plane laid out? - CORRECT ANSWERS ✔✔In a distributed
architecture.
,What is a Centralized Control Plane? - CORRECT ANSWERS ✔✔Controller-based or
Software-defined networking (SDN) where centralized software replaces the control
plane on devices.
How does a controller reach out to a piece of network equipment? - CORRECT
ANSWERS ✔✔Via the Southbound Interface using an API, SSH, SNMP, OpenFlow,
Cisco OpFlex, etc.
How does a controller interact with other applications? - CORRECT ANSWERS
✔✔Via the Northbound Interface.
What type of information can be shared between a controller and the northbound
interface? - CORRECT ANSWERS ✔✔Network topology, Lists of devices, Device
capabilities, and Device interfaces and their states.
What is OpenDaylight? - CORRECT ANSWERS ✔✔A software defined networking
solution.
Name 3 protocols that are supported by OpenDaylight on the Southbound interface. -
CORRECT ANSWERS ✔✔OpenFlow, BGP-LS, and NETCONF.
What is OpenFlow? - CORRECT ANSWERS ✔✔A software protocol that directly
interfaces with the forwarding plane.
What was the Cisco Open SDN Controller, or OSC? - CORRECT ANSWERS
✔✔Cisco's deprecated version of OpenDaylight.
, What are the 3 Cisco intent-based networking products that replaced the Cisco Open
SDN Controller? - CORRECT ANSWERS ✔✔1) Software defined WAN, or SD-WAN,
for the network edge. 2) Software defined access, or SDA, for the LAN. 3) Application
centric infrastructure, or ACI, for the data center.
What design aesthetic is used by Cisco's Application centric infrastructure, or ACI? -
CORRECT ANSWERS ✔✔A spine and leaf architecture. A small amount of spine
switches aggregate all of the leaf switches. Leaf switches in turn connect to servers,
such as the Cisco Unified Computing System, or UCS.
What is the benefit of servers such as the Cisco Unified Computing system
connecting to leaf switches in the Cisco's Application centric infrastructure? -
CORRECT ANSWERS ✔✔To provide increased capacity and redundancy.
Give 3 aspects of the physical layout of the ACI spine and leaf architecture. -
CORRECT ANSWERS ✔✔1) All servers are connected to multiple leaf switches, but
only connect to leaf switches. 2) Every spine switch is connected to every leaf switch.
3) Neither spine nor leaf switches will directly connect to other spine or leaf
switches.
Are ACI servers physical or virtual? - CORRECT ANSWERS ✔✔They can be either
and are considered endpoints.
What defines policies for ACI endpoint servers? - CORRECT ANSWERS ✔✔ACI, via
the Application Policy Infrastructure Controller or APIC.
What is the Application Policy Infrastructure Controller, or APIC? - CORRECT
ANSWERS ✔✔The centralized control software for ACI
