Refer to the exhibit. A network engineer must configure a Cisco ACI fabric that meets these requirements:
- The interface Eth1/2 must accept traffic only from EP2.
- The interface Eth1/1 must accept traffic from EP1 and EP2.
- EP1 and EP2 must authenticate independently on Eth1/1.
Which 802.1x host modes must be configured to meet these requirements?

An engineer plans a Cisco ACI firmware upgrade. The ACI fabric consists of three Cisco APIC controllers, two spine switches, and four leaf switches. Two leaf switches have 1-Gb copper ports for bare metal servers, and the other two leaf switches have 10-Gb SFP ports to connect storage.
Which set of actions accomplishes an upgrade with minimal disruptions?
A Cisco ACI leaf switch receives an ARP request packet from a host that is attached to a bridge domain with unicast routing enabled. Which information does the leaf switch learn?
A network engineer demonstrates Cisco ACI to a customer. One of the test cases is to validate a disaster recovery event by resetting the ACI fabric to factory and then restoring the fabric to the state it was in before the event.
Which setting must be enabled on ACI to export all configuration parameters that are necessary to meet these requirements?
When Layer 3 routed traffic is destined to a Cisco ACI fabric, which mechanism does ACI use to detect silent hosts?
What is a characteristic of a Cisco ACI Multi-Pod?
Which Cisco ACI feature allows the encryption of communication over TEP addresses connecting sites via the intersite network in a Cisco Multi-Site deployment?
An engineer must configure an L3Out to advertise a single summarized address for all Cisco ACI host routes. The summarized address must be advertised to the core switches that are physically attached to the ACI fabric. An external EPG is created with the required subnet. Which configuration set advertises the subnet to the remote peer?
What does a bridge domain represent?
Refer to the exhibit. An engineer must migrate workloads from the brownfield network to the Cisco ACI fabric. The VLAN 10 default gateway remains in the router located in the brownfield network. The bridge domain has already been associated with L2Out. Which two actions must be taken to migrate the workloads? (Choose two.)

Which two settings are available in a Cisco ACI contract? (Choose two.)
A Cisco APIC is configured with RADIUS authentication as the default. The network administrator must ensure that users can access the APIC GUI with a local account if the RADIUS server is unreachable. Which action must be taken to accomplish this goal?
Which role do interfaces Ethernet 1/49-50 have in this output?

For which type of endpoint entry does a Cisco ACI leaf switch keep the original TEP source address instead of rewriting the outer source IP address to its TEP address?
