Which statements about a default gateway are correct?Select all correct answers.A host sends the remote IP packet inside a local frame addressed to the gateway MACIt is used when a destination is outside the local subnetIt must always have the same IP address as the DNS serverIt is normally a router interface reachable on the local networkVLANMedium2 mark(s)8. Which statements about VLANs are correct?Select all correct answers.Devices in different VLANs normally require Layer 3 routing to communicateA VLAN creates a separate Layer 2 broadcast domainAll switch ports must carry every VLAN802.1Q can tag Ethernet frames with VLAN informationIPv4Medium2 mark(s)9.
