Infrastructure Scenario Tests

A WatchGuard Firebox M590 experiences persistent BOVPN instability to 6 branch offices due to a phase 2 SA lifetime mismatch after a firmware upgrade, causing intermittent branch connectivity.

The HPE Aruba ClearPass Policy Manager cluster primary node crashes, and the secondary node's database is out of sync, causing all 802.1X authentications to fail across the entire campus network.

All 85 Juniper Mist-managed APs lose connectivity to the Mist cloud dashboard after a rule change blocks the required outbound ports, leaving APs operational but unmanaged.

A Juniper MX480 border router experiences BGP session flapping with two upstream ISPs due to a line card memory error, causing route oscillation and intermittent internet connectivity for the entire organization.

A Juniper EX4300 virtual chassis of 4 members splits into two partitions when a VCP cable is severed during cable management, causing half the access ports to lose their trunk uplinks.

A Juniper SRX4600 chassis cluster experiences a split-brain condition when both fabric links fail simultaneously, causing both nodes to assume the primary role and creating duplicate gateways on the network.

The SonicWall TZ670 SD-WAN policy engine fails to detect WAN link degradation, continuing to route critical VoIP traffic over a congested ISP link instead of failing over to the backup MPLS circuit.

The SonicWall NSsp 13700 running carrier-grade NAT exhausts its NAT translation table, preventing new outbound connections while existing sessions remain active.

The SonicWall NSA 2700 DPI-SSL engine crashes under load, causing all HTTPS traffic to be dropped instead of bypassed, resulting in complete internet outage for 300 users.

A SonicWall TZ670 content filter policy update blocks access to a critical cloud accounting application by miscategorizing it as gambling/gaming, affecting all finance department workflows.

The PA-3260 URL filtering database becomes corrupted during an update, causing all web traffic to be categorized as 'not-resolved' and bypassing URL filtering policies entirely.

The PA-5250 WildFire cloud connection fails, causing all unknown file verdicts to default to 'allow' per policy. Potentially malicious files bypass inspection for 3 hours before detection.

Panorama loses connectivity to all 12 managed PA firewalls after a network change isolates the management VLAN. Firewalls continue forwarding but cannot receive policy updates or log to Panorama.

A Palo Alto threat prevention content update incorrectly classifies ERP traffic as a command-and-control callback pattern, blocking all employee access to the SAP ERP system.

The Palo Alto PA-5250 GlobalProtect gateway stops accepting new VPN connections after a configuration push corrupts the portal agent configuration. 400 remote workers cannot connect.

A managed client's secondary ISP failover fails to activate when the primary circuit goes down. The SD-WAN appliance detects the primary failure but the secondary circuit is disconnected due to an unpaid bill. The site is completely offline.

The network TAP aggregating traffic for the IDS/IPS and packet capture system becomes oversubscribed. The 10G TAP is receiving 14Gbps of traffic, causing 28% packet loss on the monitoring feed. The IDS misses attack signatures and the packet capture has gaps.

A switch firmware upgrade resets QoS policies on 12 access switches, removing DSCP marking and priority queuing for voice traffic. VoIP call quality degrades severely during business hours when data traffic competes with voice.

A RADIUS policy change breaks MAC Authentication Bypass (MAB) for IoT devices. Security cameras, badge readers, and building management sensors are all locked out of the network as they cannot perform 802.1X EAP authentication.

The IP Address Management system shows all subnets in the production VLAN are fully allocated. DHCP scopes have no available leases, and new devices cannot obtain IP addresses. Server provisioning and workstation deployment are both blocked.
