Cisco 200-301 Exam Dumps, Practice Test Questions

One shared untagged port group would place both virtual adapters in the same Layer 2 segment, contrary to the isolation requirement.

Enabling routing makes inter-subnet connectivity possible and is not a substitute for mapping guest vNICs to the correct VLANs.

Guest RAM allocations do not tag Ethernet frames or select which virtual switch broadcast domain a vNIC joins.

Switch MAC learning associates the source address of incoming frames with the ingress port; destination is used only for lookup.

ARP resolves IP-to-MAC neighbors and is not the mechanism for learning each station’s source MAC and port in a VLAN.

MAC learning is VLAN-scoped to the frame’s ingress VLAN, not an all-VLAN global assignment.

Flooding is used for unknown unicast or broadcast; a learned destination enables selective forwarding on Gi1/0/8.

The frame remains in the same VLAN and destination-MAC switching uses the learned egress without routing.

A known destination in a forwarding VLAN should be delivered to its learned interface unless a separate filtering condition exists.

Normal Ethernet switching floods unknown unicast within the ingress VLAN until the destination MAC can be learned.

VLANs isolate broadcast/unknown-unicast domains, so unknown traffic must not cross into unrelated VLANs.

This is a Layer 2 unknown destination frame; a route lookup is not a substitute for VLAN-local unknown-unicast flooding.

All-ones Ethernet destination is broadcast and must be flooded to eligible forwarding ports in the VLAN.

Broadcast scope is bounded by the VLAN and must not leak to unrelated Layer 2 broadcast domains.

An Ethernet broadcast is a Layer 2 delivery pattern; it does not imply off-subnet IP routing.

Aging is designed to remove inactive learned mappings so forwarding can adapt to host movement.

Ordinary dynamic CAM learning does not automatically configure persistent sticky port-security identities.

Aging invalid entries preserves selective forwarding for active learned destinations and is not equivalent to uncontrolled flooding.

When a source is learned on Gi1/0/10 in the same VLAN, ordinary MAC-learning updates the port mapping.

A single learned unicast MAC normally has one current forwarding port per VLAN to avoid ambiguity.

This Layer 2 source location update does not require a routed destination-prefix change.

Flooding beyond VLAN 30 would cross isolation boundaries and leak traffic into a separate broadcast domain.

An unknown unicast MAC lookup is a Layer 2 decision; it is not resolved by routing the destination IP through a default route.

The STP root-port role does not make VLAN 40 the correct destination for VLAN 30 unknown unicast.

IP routing tables hold destination prefixes and next hops, not VLAN-scoped learned source-MAC entries.

ARP can resolve IPv4 addresses to MACs but does not enumerate the specific switch MAC-table interface learning.

A trunk command reports VLAN carriage and trunk attributes, not every MAC-to-port association.

MAC learning shows Layer 2 location but does not prove a usable remote route and ARP/ND adjacency.

STP root selection does not directly validate the remote IP destination prefix or gateway resolution.

IP forwarding on Ethernet ordinarily needs adjacent next-hop link-layer resolution; disabling it breaks connectivity.

An IP default gateway is a Layer 3 address/route decision, not a replacement for VLAN-scoped Ethernet source-MAC learning.

The learned Gi1/0/8 destination location is not rewritten from a frame that only lists that address as its destination. Source learning uses the frame sender, not the receiver.

MAC table entries are Layer 2 forwarding records; an IPv4 /32 route represents an IP prefix and cannot be formed from a MAC address.
