C. Dynamic Auto(The Default Switchport MOde for Cisco Catalyst Switches Is Dynamic Auto)

What is the Default Switchport mode for Cisco Catalyst Switches ? A.Access B.Trunk C.Dynamic Auto D.Dynamic Desirable

All answers are True. VLAN 1 is the default native and management VLAN. All switch ports are by default assigned to this VLAN. VLAN 1 cannot be renamed nor deleted.

Which is true of VLAN 1? (Choose all that apply.) ALLL

Trunk and dynamic desriable

Which two DTP modes will form a trunk with an interface that is configured as dynamic auto? (Choose two.) A. Access B.Trunk C. Dynamic Auto D. Dynamic Desirable

B.Native(The native VLAN is assigned to 802.1Q trunk ports to carry untagged traffic.)

Which type of VLAN is assigned to 802.1Q trunk ports to carry untagged traffic? A.Default B.Native C.Data D.Mangement

B.False(The correct answer is False. DTP is a Cisco proprietary protocol for switchport trunk auto negotiation.)

True or false? DTP is an open standard IEEE protocol that specifies auto negotiation of switch trunk links. A.True B.False

(The correct answer is False. A switchport configured as dynamic auto will only form a trunk with another interface configured as either trunk or dynamic desirable.)

True or False?Two Switchports On a Link Both Configured Dynamic Auto Will Successfully Negotiate A Trunk A.True B.False

B.False(The correct answer is False. By default, the native VLAN is VLAN 1, however it is best practice to configure the native VLAN to be an unused VLAN.)

True or False? It is a best practice to configure the native VLAN as VLAN 1. A.True B.False

A.True (The correct answer is True. Traffic generated within a VLAN remains within that VLAN and is completely separated from other parts of the network.)

True or False? VLANs can improve security by isolating sensitive data from the rest of the network. A.True B.False

A.True(The correct answer is True. A VLAN is a logical broadcast domain that can span multiple LAN segments. This can improve network performance by segmenting large broadcast domains into smaller broadcast domains. Broadcast frames are not forwarded between VLANs.)

True or False? VLANs improve network performance by segmenting broadcast domains. A.True B.False
