An engineer is configuring multicast on a Cisco router. The router receives multicast traffic from a source on interface GigabitEthernet0/0 and needs to forward it to receivers on interface GigabitEthernet0/1. The engineer enables PIM sparse mode on both interfaces and configures a static RP. However, the router does not create a multicast routing entry for the (S,G) pair. What is the most likely missing configuration?

A company has a core network running OSPF in a single area (area 0). The network consists of four routers: R1, R2, R3, and R4. R1 is connected to R2 and R3. R2 is also connected to R4. R3 is also connected to R4. All links are GigabitEthernet with OSPF cost based on bandwidth (reference bandwidth 100 Gbps). The network engineer notices that traffic from R1 to a subnet behind R4 is taking a suboptimal path: R1 -> R2 -> R4, instead of R1 -> R3 -> R4 which has lower cost. Upon checking OSPF neighbor states, all adjacencies are full. The engineer verifies that the cost on the R1-R3 link is 10 and the cost on the R3-R4 link is 10, while the R1-R2 link cost is 20 and the R2-R4 link cost is 20. The total cost via R2 is 40, via R3 is 20. However, the routing table on R1 shows the next-hop as R2 for the subnet behind R4. What is the most likely cause?

A company has a large network of 500 Cisco IOS XE routers and switches spread across multiple sites.

They have written a Python script using Netmiko to connect to each device, run 'show interfaces', and parse the output to extract key metrics (e.g., input/output errors, packets per second). The script works correctly when tested on a small subset of devices, but when run against all 500 devices, it takes too long (over 2 hours) and sometimes fails due to SSH connection timeouts.

A financial services company has deployed Cisco UCS servers with VMware vSphere 7.0 to host critical trading applications. The network uses Cisco Nexus 9000 switches in a VXLAN EVPN fabric with BGP as the underlay. The environment includes 50 ESXi hosts, each connected via two 40G interfaces to two different leaf switches in a VPC. The VMs are spread across multiple hosts and communicate over VXLAN. Recently, the operations team migrated a set of VMs from an old VLAN-based network to a new VXLAN segment (VNI 50000). After the migration, users report intermittent connectivity issues and packet loss. The engineering team captures traffic and notices that some VMs send ARP requests that are not being replied to, even though the target VM is active. Further analysis shows that the ARP requests are being flooded to all VTEPs, but the replies are not reaching the source. The team checks the underlay and finds no issues with BGP or routing.

Frequently asked questions

What does the python for network automation domain cover on the 350-401 exam?
python for network automation questions test whether you can apply the concept in context, not just recognise a definition.
How many questions are in this domain?
This page lists all 1809 python for network automation questions in the 350-401 question bank. The actual exam draws from this domain proportionally to its weighting in the official exam blueprint.
What is the best way to practise this domain?
Start with a short focused session (10 questions) to identify gaps, then work through explanations. Repeat with a longer session once the weak areas feel solid.
Can I practise only python for network automation questions?
Yes — the session launcher on this page filters questions to this domain only. Choose any session length for inline explanations and scoring.
