Free 300-620: Implementing Cisco Application Centric Infrastructure (DCACI) Exam Questions and Answers
Implementing Cisco Application Centric Infrastructure (DCACI) is exam 300-620, part of Cisco certifications. In Cisco's current scheme the first digit gives the level: 100 is entry, 200 associate, 300 the CCNP concentration exams, 350 the CCNP core exams that also qualify you for CCIE, 500 specialist and 700 the unproctored sales exams. Older codes such as 400-, 640- and 642- predate the February 2020 restructure, when every CCNA track was collapsed into one exam and CCNP moved to a core-plus-concentration model.

Question #1
An ACI administrator notices a change in the behavior of the fabric. Which action must be taken to determine if a human intervention introduced the change?
Please select an optionIncorrectCorrect answer: C
The audit log in the APIC GUI records user events and configuration changes, so it reveals whether a human introduced the behaviour change. Event records and CLI history do not give the full user-action audit trail.
Was this answer correct?Question #2
Which type of policy configures the suppression of faults that are generated from a port being down?
Please select an optionIncorrectCorrect answer: C
A fault severity assignment policy lets the administrator squelch (suppress) a fault such as the one raised when a port goes down, so it is no longer reported.
Was this answer correct?Question #3
A situation causes a fault to be raised on the APIC. The ACI administrator does not want that fault to be raised because it is not directly relevant to the environment. Which action should the administrator take to prevent the fault from appearing?
Please select an optionIncorrectCorrect answer: C
Right-clicking a fault and choosing Ignore Fault creates a fault severity assignment policy that squelches that fault so it no longer appears. Acknowledging only marks it and does not stop it from being raised again.
Was this answer correct?Question #4
A RADIUS user resolves its role via the Cisco AV Pair. What object does the Cisco AV Pair resolve to?
Please select an optionIncorrectCorrect answer: B
The Cisco AV pair (shell:domains=domain/writeRoles/readRoles) assigns the external user roles within a security domain, so the AV pair resolves to a security domain.
Was this answer correct?Question #5
An engineer is implementing Cisco ACI at a large platform-as-a-service provider using APIC controllers, 9396PX leaf switches, and 9336PQ spine switches. The leaf switch ports are configured as IEEE 802.1p ports. Where does the traffic exit from the EPG in IEEE 802.1p mode in this configuration?
Please select an optionIncorrectCorrect answer: A
In IEEE 802.1p mode the leaf sends the frame with a VLAN 0 tag so the CoS bits are preserved while no VLAN ID is carried. It is not a plain untagged frame.
Was this answer correct?Question #6
How is an EPG extended outside of the ACI fabric?
Please select an optionIncorrectCorrect answer: D
An EPG is extended outside the fabric by statically binding a leaf port and VLAN ID to the EPG, so external devices in that VLAN become members of the EPG.
Was this answer correct?Question #7
Where is the COOP database located?
Please select an optionIncorrectCorrect answer: B
The Council of Oracle Protocol database holding endpoint-to-VTEP mappings is maintained on the spine switches; leaves report learned endpoints to the spines.
Was this answer correct?Question #8
Which description regarding the initial APIC cluster discovery process is true?
Please select an optionIncorrectCorrect answer: A
The APIC assigns itself and the switches internal TEP addresses from the infrastructure pool and uses them to communicate with fabric nodes. APICs discover each other via LLDP, and discovery starts with the leaf switches.
Was this answer correct?Question #9
Refer to the exhibit. Which two components should be configured as route reflectors in the ACI fabric? (Choose two.)
Select 2 answers.
Please select an optionIncorrectCorrect answer: A, C
MP-BGP route reflection in an ACI fabric is performed by the spine switches, which reflect external routes learned by border leaves to all other leaves. Leaves are clients and the APICs take no part in BGP.
Was this answer correct?Question #10
What does a bridge domain represent?
Please select an optionIncorrectCorrect answer: B
A bridge domain is a Layer 2 forwarding construct within the fabric that defines a broadcast domain; it is associated with a VRF and can contain one or more subnets.
