Each of these topics contains the specific technical skills that the candidates must master before attempting this test. They are as follows:
ACI Fabric Infrastructure: The learners need to demonstrate their ability to explain ACI hardware as well as topology; explain ACI Object Model; apply audit log, faults, event record; determine ACI fabric discovery; apply ACI policies such as fabric and access; apply ACI logical constructs (consumer, tenant, reverse port filter, filter, provider, VRF enforced; VRF; bridge domain, including unicast routing, Layer 2 unknown hardware proxy, ARP flooding; application profile; EPG endpoint groups).
ACI Packet Forwarding: The skills measured in this objective include describing endpoint learning; applying bridge domain configuration (ARP flooding; Layer 2 unidentified hardware proxy; unicast routing).
External Network Connectedness: In the framework of this section, the individuals are required to prove that they are capable of applying Layer 2 out (STP/MCP fundamentals) as well as applying Layer 3 out (excludes transit routing as well as VRF route leaking).
Integrations: This subject checks one’s ability to integrate VMware vCenter DVS; explain resolution immediateness within VMM; apply managed as well as unmanaged graph.
ACI Management: The domain covers your skills, such as applying out-of-band as well as in-band; applying syslog as well as snmp services; executing configuration backup (config or snapshot import export); executing AAA and RBAC; configuring an update.
ACI Anywhere: Within this topic area, the examinees should prove their competency in explaining multipod as well as determining multisite.
NEW QUESTION 32
Refer to the exhibit.
Which action should be taken to ensure authentication if the RADIUS servers are unavailable?
- A. Assign the user to the default role.
- B. Set the default login realm to LDAP
- C. Adjust the priority of server 10.1.1.1 to 1.
- D. Set the fallback login to local.
Answer: D
Explanation:
Explanation
Changing the server priority is not logical answer.
The command "aaa user default-role no-login" means that remote users who do not have a user role cannot login. This means that assigning the user to default role will not be able to login.
The "aaa authentication login default" and "aaa authentication login fallback" has identical configuration. The fallback uses RADIUS server. We should change is to local.

- C. Endpoint information is not exchanged across sites unless COOP protocol is used.
