Why is the answer to knowledge Check 7.4 an ingress controller?


The preceding material literally states "As security has become more of a concern, ingress controller pods are no longer given access to low-numbered ports." - Why is Ingress Controller the correct answer to this question then?

    Hi @adzee95,

    I would argue the statement is rather firm. There is such a security concern over allowing ingress controllers access to low numbered ports, however, it may be up to the user's discretion whether to configure such a port mapping.

    As far as the question itself, it may be ambiguous, because even the ClusterIP exposes a port, that can be a low numbered port of the application (visible only within the cluster, of course). Perhaps the question is just missing a clarifying term "externally", that would help to select the desired answer.
