Automating Cisco Enterprise Solutions (ENAUTO) Free Practice Test — 30 Questions

Question 1

Consider a network automation engineer tasked with ensuring a specific access control list (ACL) entry, `permit tcp host 10.1.1.5 host 192.168.5.20 eq 80`, is present on multiple Cisco IOS devices within a branch office. The existing ACLs on these devices are complex and managed by different teams, meaning the order of existing entries and the presence of other unrelated `permit` or `deny` statements should ideally remain undisturbed. Which Ansible module and approach would best guarantee the desired state of this specific ACL entry while minimizing the risk of unintended configuration changes on the devices?

Accepted Answer

Use the `cisco.ios.ios_acl` module with a `lines` parameter that includes the specific `permit` statement, relying on the module's inherent idempotency to add the line if it's missing, without affecting other lines.

Question 2

A global enterprise, operating a complex and critical network infrastructure, is planning a significant firmware upgrade for its entire fleet of Cisco Catalyst 9000 series switches. The upgrade is mandated to enhance security posture and improve performance metrics. Given the distributed nature of the network and the potential for service disruption, what is the most prudent strategy to implement this automated firmware update, ensuring minimal impact on business operations while maximizing success probability?

Question 3

An enterprise network automation team is responsible for deploying standardized configurations to a fleet of Cisco routers and switches. They utilize a Python-based automation framework with Jinja2 templating to generate device configurations from a central inventory and data source. Recently, an issue has surfaced where a subset of newly deployed devices is incorrectly assigned to the `Mgmt` VRF for their management interfaces, deviating from the intended `Global` VRF assignment specified in the master configuration data for those specific devices. The automation workflow successfully provisions other configuration elements on these affected devices, and other devices deployed concurrently with identical source data entries are correctly configured. Analysis of the source data for the affected devices reveals that the management VRF field is present but contains an empty string (`""`) for these specific entries, rather than being omitted entirely or explicitly set to `Global`. The automation script\'s templating logic includes a conditional statement that is intended to assign the `Global` VRF if no specific VRF is provided.

Which of the following best describes the underlying issue and the most effective approach to rectify it?

Accepted Answer

The automation logic fails to correctly interpret an explicitly defined but empty string value for the management VRF parameter, causing it to incorrectly fall back to a default VRF assignment. The solution involves enhancing the data validation and transformation layer to explicitly handle and sanitize empty string values for VRF assignments, ensuring they are treated as unassigned or explicitly set to the intended default.
