Reference bandwidth sets the numerator; it is not simply used as every interface's cost regardless of link speed.

Router ID distinguishes routers and can break some election ties; it does not determine OSPF cost derived from bandwidth settings.

The lower-bandwidth link generally receives a higher path cost, so reversing 1 and 10 contradicts the stated reference/bandwidth calculation.

Power changes may enlarge the cell but cannot remove a reinforced wall or microwave interference and may worsen nearby co-channel contention. Survey the path first.

Channel changes can help if based on a site survey. Blindly choosing an overlapping high-interference channel does not resolve attenuation or RF interference from the stated obstacles.

The wall and interfering equipment affect physical propagation and noise. Suppressing recovery behavior cannot create a stronger usable signal; measure RF conditions and reposition or retune.

The IP default route affects routed destinations and cannot prevent tagged VLAN 35 Ethernet frames from traversing the interswitch trunk.

Deleting the VLAN removes or disrupts local membership on that switch, exceeding the requirement to isolate only one link.

Native VLAN changes how untagged traffic is classified and do not specifically remove tagged VLAN 35 from an allowed list.

A DNS resolver address is not an appropriate substitute for the actual adjacent router next hop, and does not change the wrong destination prefix.

Copying the same erroneous prefix produces another route to the wrong destination. Administrative distance does not transform 10.82 into 10.28.

STP bridge priority affects Layer 2 path choices; it cannot cause a router to match an incorrect IP destination network.

A VLAN identifier may appear in a message body but is not a universal syslog facility category in its standard priority header.

Routing cost influences OSPF path preference and is unrelated to syslog facility numbering or process-type classification in event logs.

Severity levels indicate urgency, from emergencies through debugging, not the facility/source category. Mixing these prevents proper alert routing.

Wildcard 63 allows six host bits and matches a /26 block, twice the intended 32-address range for /27.

Supplying the subnet mask as wildcard would make its 1 bits variable and 0 bits fixed, producing a very different match than intended.

Wildcard 15 covers only 16 addresses and is narrower than the desired /27. Half the intended sources would fail to match.

ARP resolves local IPv4 neighbors and cannot submit a policy-intent request to the controller's management API.

Southbound methods operate toward the managed switch/router infrastructure and are not the application-to-controller API layer described.

OSPF is a dynamic routing protocol for router neighbor and topology exchange, not the general SDN application intent API.

Hop count alone is not the OSPF SPF cost metric. A route with fewer hops can have higher cumulative interface cost.

Router ID can affect protocol identity and DR ties, but it is not the usual preference rule between these different calculated OSPF costs.

Equal-cost multipath requires identical eligible total costs; 20 and 25 are different, so both are not installed as equal.

Containers consume shared host CPU, memory and kernel resources; namespaces do not make them fully separate physical machines or eliminate host-level isolation risks.

VLANs can segment container networking but are not the entire compute/runtime virtualization boundary, which includes kernel namespaces and resource controls.

Full guest kernels and virtual hardware are characteristic of many VMs, not a default requirement for each ordinary container instance.

BPDU Filter suppresses BPDU processing or transmission and may hide the very control information needed to prevent a loop.

PortFast is intended for true edge attachments and can increase loop risk on a redundant switch-to-switch link rather than prevent this condition.

Root Guard addresses superior BPDUs threatening a designated port's root placement. The failure here is missing expected BPDUs on a non-designated port, the Loop Guard case.

Transport mode is part of IPsec and uses negotiated security associations. NAT alone is not a cryptographic replacement.

The new outer IP header is characteristic of tunnel mode, not the transport-mode distinction requested.

ESP can provide confidentiality and integrity as configured in either mode; choosing transport mode does not prohibit those protections.
