Question#1

Target clients running Podman must be able to pull this image directly from the Satellite server's FQDN on port 443.

A. Execution Path (CLI Method):

Question#2

The output must be a clean CSV containing only the Hostname and the OS Version.

A. Execution Path (CLI Method):
Use the hammer host list command with advanced search operators for CVEs
hammer --csv host list --search "hostgroup = PCI_Zone and cve = CVE-2023-4807" --fields "Name,Operating System" > /tmp/pci_vulnerability_report.csv
Grading Engine Teardown & Pitfalls: [Syllabus Domain: Manage systems / Apply updates to selected hosts]
✑ The Errata vs. CVE Trap: Candidates often try to search for the Errata ID (RHSA-xxxx:xxxx). However, a single CVE can be patched by multiple different Errata depending on the major/minor OS release (RHEL 7 vs RHEL 8). Satellite natively parses the OVAL data from Red Hat. By querying the cve = parameter directly, the Foreman database automatically aggregates all associated Errata across all OS versions, ensuring zero vulnerable hosts slip through the report.

Question#3

The automated provisioning must trigger instantaneously without human intervention in the WebUI.

A. Execution Path (CLI Method):

Question#4

You must ensure existing RHEL clients do not permanently lose trust with the Satellite server's content engine (Pulp) after the cutover.

A. Execution Path (CLI Method):

Question#5

You must orchestrate the rollback using a single Satellite Remote Execution job.

A. Execution Path (CLI Method):
The architect must know the exact DNF sequence to tear down a module and install a different stream.
hammer job-invocation create --job-template "Run Command - SSH Default" --inputs command="dnf module reset nodejs -y && dnf module enable nodejs:16 -y && dnf distro-sync -y" --search-query "hostgroup = Web_Frontends"
Grading Engine Teardown & Pitfalls: [Syllabus Domain: Run remote jobs on managed hosts / Apply updates to selected hosts]
✑ The Modularity Trap: This is a classic RHEL 8/9 trap. An AppStream module is not a standard RPM. You cannot simply "remove" or "downgrade" it if you are jumping between streams (e.g., 18 to 16). The stream itself must be explicitly reset, then the new stream must be enabled, and finally, a distro-sync (or install) is required to swap the underlying RPM profiles. If a candidate attempts a standard RPM downgrade via REX, the DNF engine on the clients will violently reject the transaction, leaving the outage unresolved
