Cisco Appliction Centric Infrastructure
EXAM WITH ANSWERS
Define ACI - CORRECT ANSWERS ✔✔is a comprehensive SDN architecture. It
provides policy based automation solution to integrate physical and virtual
environments under one policy model for network, servers, storage, services, and
security.
Cisco ACI is built on - CORRECT ANSWERS ✔✔The Cisco APIC
The Cisco ACI fabric
The Cisco ACi partner ecosystem.
Describe Cisco ACI (Application-Centric Infrastructure) - CORRECT ANSWERS
✔✔Cisco ACI combines the full mesh spine-and-leaf topology with finely tuned
routing and several portocols that allow network abstraction form physical
infrastructure.
What protocol is routed to endpoints in a spine-and-leaf topology during the Cisco
ACI fabric initialization stage. - CORRECT ANSWERS ✔✔IS-IS
What is an ANP? - CORRECT ANSWERS ✔✔Application Network profile, all
forwarding inthe fabric is managed by the ANP, which defines the application
communication requirements.
How is a policy pushed from the Cisco APIC to the fabric switch? - CORRECT
ANSWERS ✔✔-An endpoint attaches to the fabric (leaf switch)
, -Cisco APIC detects the endpoint and its designated EPG (end point group)This is
based on previous configuration.
-The Cisco APIC pushes the required policy(all policies with EPG listed as either the
source or destination) to the leaf switch.
-The ACI farbric instantiates the policy by provisioning the stateless hardware.
Cisco ACI specifications are sufficient for a large-scare data center support? -
CORRECT ANSWERS ✔✔over one millions IPv4 and IPv6 endpoints.
over 64,000 tenants
over 55,000 1/10G hosts in a single tier.
ALl host traffic that connects at the leaf is carried over? - CORRECT ANSWERS
✔✔The inegrated overlay.
Cisco ACI fabric is composed of? - CORRECT ANSWERS ✔✔The Cisco APIC and
the Cisco 9K series spiend and leaf switches.
advantages of aspine and leaf topology - CORRECT ANSWERS ✔✔-Simple and
consistent topology
-Scales out to support more connectivity and bandwidth
-Symmetrical topology that optimizes forwarding behavior.
-Least-cost design for hight bandwidth, low latency, and low oversubscription that
works at a variable scale
How are Loopback address used in Cisco ACI - CORRECT ANSWERS ✔✔Loopback
addresses are teh VTEPs that are used in the integrated overlay and advertised to all
other nodes in the fabric for overlay tunnel use.
