Q

Cisco Catalyst switches CAT1 and CAT2 have a connection between them using ports FA0/13. An 802.1Q trunk is configured between the two switches. On CAT1, VLAN 10 is chosen as native, but on CAT2 the native VLAN is not specified. What will happen in this scenario?

802.1Q giants frames could saturate the link.
VLAN 10 on CAT1 and VLAN 1 on CAT2 will send untagged frames.

VLAN 10 on CAT1 and VLAN 1 on CAT2 will send tagged frames.

A

VLAN 10 on CAT1 and VLAN 1 on CAT2 will send untagged frames.

82
Q

What are three advantages of having a single trunk link on a switch and subinterfaces on the router instead of individual VLAN links between a switch that has three VLANs and a router to route between the VLANs? (Choose three.)

A

It would free two switch and router ports
It would reduce the complexity of the cabling run
It would allow adding more VLANs without requiring more cabling or switch ports

83
Q

How does the router-on-a-stick model for inter-VLAN routing differ from traditional routing?

A

The router-on-a-stick model uses subinterfaces on the router with only the no shutdown command issued on the physical interface.

Router-on-a-stick
Multilayer switch-based routing

87
Q

A

The physical port on the router is shut down

One or both of the router subinterfaces have been configured with an IP address in a different network

88
Q

When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default?

A

native VLAN ID

89
Q

What happens to a port that is associated with VLAN 10 when the administrator deletes VLAN 10 from the switch?

A

The port becomes inactive

90
Q

Which DTP switchport mode allow the port to create a trunk port if the the port is in trunk, dynamic auto and dynamic desirable mode?

A

Dynamic Desirable

91
Q

What is the function of the command switchport trunk native vlan 999 on a trunk port?

A

It designates VLAN 999 for untagged traffic.

92
Q

Which IEEE standard protocol is initiated as a result of successful DTP completion in a switch over Fast Ethernet?

A

802.1Q.
Dynamic Trunking Protocol (DTP) is a Cisco proprietary protocol for negotiating trunking on a link between two devices and for negotiating the type of trunking encapsulation (802.1Q) to be used.

93
Q

Which three of these statements regarding 802.1Q trunking are correct? (Choose three)

A
  1. 1Q native VLAN frames are untagged by default.

802. 1Q trunks should have native VLANs that are the same at both ends.

94
Q

What are three advantages of having a single trunk link on switch and subinterfaces on the router instead of individual VLAN links between a switch that has three VLANs and a router to route between the VLANs

A

It would free two switch and router ports
It would reduce the complexity of the cabling run
It would allow adding more VLANs without requiring more cabling or switch ports

Q

How does the router-on-a-stick model for inter-VLAN routing differ from traditional routing?
