A large financial institution has a Cisco ACI fabric with multiple tenants. The security team requires that all management access to the APIC controllers be authenticated via multi-factor authentication (MFA) using a RADIUS server. The RADIUS server is configured to send a One-Time Password (OTP) challenge during authentication. The current configuration uses local authentication. The engineer needs to implement RADIUS authentication with MFA for APIC GUI and CLI access. The RADIUS server is reachable at 10.10.10.10, shared secret 'SecureSecret123'. The APIC is running software version 4.2(3). The engineer must ensure that local authentication is used as fallback if the RADIUS server is unreachable. Which of the following actions should the engineer take?

A Cisco MDS 9000 switch is used in a storage network. The security policy requires that a junior administrator named 'user1' can view zone configurations but cannot make any changes. Currently, 'user1' is assigned the default 'network-operator' role, which allows read-only access to most configuration, but the engineer wants to ensure that zone modification is explicitly denied. The engineer creates a custom role named 'zone-viewer' and assigns it to 'user1'. The role should permit viewing of the running configuration related to zones but deny any command that modifies zone or zoneset configurations. Which configuration best achieves this objective?

A large enterprise runs a multi-site Cisco ACI fabric with APICs in a cluster. The automation team uses Python scripts with the Cobra SDK to create and manage tenant policies. Recently, after upgrading the APIC firmware from version 4.2(3) to 5.2(1), a script that previously worked now fails with an 'Unauthorized' error when calling the APIC REST API. The script uses a service account with a locally stored password. The automation engineer verifies that the account credentials are correct and that the account is not locked. The script was not modified during the upgrade. Which action should the engineer take to resolve the issue?

An engineer is troubleshooting a BGP EVPN issue where leaf switches are not learning remote MAC addresses. The underlay is reachable and BGP sessions are established. What is a likely cause?

A data center engineer is troubleshooting connectivity issues between two EPGs in the same tenant on a Cisco ACI fabric. The first EPG 'web_epg' is in VLAN 100 and the second EPG 'db_epg' is in VLAN 200. The contract 'web_to_db' allows TCP port 3306 from web_epg to db_epg. The EPGs are in the same VRF. The engineer has verified that the physical connectivity is correct and the endpoints are learning their IP addresses. However, traffic from web_epg to db_epg is not reaching the destination. The engineer checks the contract and sees that the subject 'mysql_access' has filter 'mysql' with direction 'both'. The provider is db_epg and consumer is web_epg. The engineer also notices that the default action in the contract is 'deny'. What is the most likely cause of the issue?

An engineer is deploying FCoE on a Cisco Nexus 9000v switch in a converged network. The storage array is connected via native Fibre Channel to an MDS switch, and the MDS is connected to the Nexus using an FCoE link. The engineer creates a virtual Fibre Channel (VFC) interface on the Nexus, binds it to an Ethernet interface, and maps VSAN 200 to VLAN 200. The MDS side has an FCoE port configured and enabled. Servers connected to the Nexus with FCoE initiators can successfully log into the storage targets, but performance is very poor and intermittent. The engineer checks for drops on all interfaces and finds none. The engineer also verifies that the FCoE VLAN is not blocked by spanning tree. What is the most likely cause of the performance issue?
