- BThe interface has been shutdown.
- CThe interface is already associated with another Eth-trunk.
- DThe interface is an access port.
2 Link Aggregation
(Multiple Choice) What benefits does port aggregation yield? (Select 3 Answers)- AImproves link bandwidth
- BImplements load sharing

- BThe same source or destination MAC address.
- CThe same protocol type
- DThe same source or destination port number.
4(Single Choice) ( ) The network administrator wishes to forward data over an Eth-trunk, however associated member interfaces operate at different rates. In terms of the resulting behavior, which of the following is true?
- AThe two switches will not be able to communicate.
- BThe higher rate member interfaces may incur packet loss.

9VLAN Principles
(Multiple Choice) An access port on a switch generally connects to a port on a computer. Which of the following statements are true? (Select 3 Answers)- AAfter receiving a tag packet, the switch forwards it directly.
- BAfter receiving an untag packet, the access port attaches its PVID information to the packet.
- CAn access port can belong to only one VLAN.
- DThe default VLAN of an access port is the VLAN where the port is located. You do not need to manually configure a default VLAN for an access port.
10(Single Choice) A Trunk port always sends tagged frames to the peer equipment.
- ATrue
- BFalse
11VLAN Principles
(Multiple Choice) A trunk port is configured to permit vlan 3, vlan4 and vlan 5 to pass. The frames of vlan 3 and vlan 4 are tagged but the frames of VLAN 5 are untagged. Which of the following may cause the problem?- APort PVID is 5
- BGVRP is enabled on this port
- COnly the command port trunk permit vlan 3 4 was configured for the trunk port.
- DPort PVID is 3 and 4
12VLAN Principles
(Single Choice) Switch-A and Switch-B are configured with ports in VLANs for R&D Department, Sales Department, Product Department, Financial Department, and HR Department. Each VLAN contains 20 users. In this case, how many subnets at least are required to provide routes between all VLANs?- A5
- B20
- C50
- D100
13(Multiple Choice) Which of the following steps are necessary to configure a port to the specified vlan in SYSTEM view? (Select 2 Answers)
- AEnter the VLAN view
- BAssign VLAN for the Ethernet port
- CSpecify description for VLAN or VLAN interface
- DSpecify proportion of broadcast storm for VLAN

- BSend the packets to all trunk links.
- CSend the packets to all trunk links that allow this VLAN to pass.
- DSend the packets out of other ports that belong to the same VLAN.
15For VLAN link type,the link between a switch and a PC is ( ).
- AAccess link
- BTrunk link
- CISL link
- DHybrid link
16VLAN Principles
(Multiple Choice) Which of the following statements about the advantages of the VLAN function are true? (Select 2 Answers)- AThe VLAN function reduces network costs by reducing the number of physical ports on switches.
- BThe VLAN function improves network security by identifying users that are allowed to access sensitive data and applications.
- CThe VLAN function improves network performance by implementing flow control and using the window advertisement mechanism.

17Which of the following technologies can reduce the scope of broadcast domain?
- AVLAN
- BTrunk
- CSTP
- DRARP
18VLAN Principles
Of all the VLAN grouping methods, the grouping method by IP address is called ( ) VLAN- APort-based
