Exercise 9.3 pod named nettool instead of ubuntu


During exercise 9.3 working with core DNS, the pod i created based on nettool.yaml was named nettool in stead of ubuntu.
This caused me to have to adjust tasks 2 and 11, so in stead of writing:
"kubectl exec -it ubuntu -- /bin/bash"
to access the pod i wrote:
"kubectl exec -it nettool -- /bin/bash"

This allowed me access to the nettool pod and i was able to do all tasks
except for 14 where the "dig nginx.test.io" command failed
root@nettool:/# dig nginx.test.io

; <<>> DiG 9.16.1-Ubuntu <<>> nginx.test.io
;; global options: +cmd
;; connection timed out; no servers could be reached

Maybe the exercise needs a revision or i did somethin wrong.
But i did not understand what wrong i did.

Any advice?
