Q6. What is a requirement to configure a trunking EtherChannel between two switches?
- The participating interfaces must be assigned the same VLAN number on both switches.
- The participating interfaces must be on the same module on a switch.
- The participating interfaces must be physically contiguous on a switch.
- The allowed range of VLANs must be the same on both switches.
Explanation: To enable a trunking EtherChannel successfully, the range of VLANs allowed on all the interfaces must match; otherwise, the EtherChannel cannot be formed. The interfaces involved in an EtherChannel do not have to be physically contiguous, or on the same module. Because the EtherChannel is a trunking one, participating interfaces are configured as trunk mode, not access mode.
Q7. A network administrator would like to ensure that router R1 is always elected the active router for an HSRP group. Which set of commands would ensure the required results?
- R1(config-if)# ip address 192.168.1.250 255.255.255.0 R1(config-if)# standby 1 ip 192.168.1.1 R1(config-if)# no shutdown
- R1(config-if)# ip address 192.168.1.100 255.255.255.0 R1(config-if)# standby 1 ip 192.168.1.1 R1(config-if)# standby 1 priority 255 R1(config-if)# standby 1 preempt R1(config-if)# no shutdown
- R1(config-if)# ip address 192.168.1.100 255.255.255.0 R1(config-if)# standby 1 ip 192.168.1.1 R1(config-if)# standby 1 priority 1 R1(config-if)# no shutdown
- R1(config-if)# ip address 192.168.1.100 255.255.255.0 R1(config-if)# standby 1 ip 192.168.1.1 R1(config-if)# standby 1 priority 150 R1(config-if)# no shutdown
Explanation: In order to configure HSRP, the standby command is used. The IP address given with the standby command is the virtual IP address used by hosts as a default gateway. A priority number of 255 is the highest that can be assigned and should be configured on the router that is to be the active router.

Q9. Fill in the blank.
In FHRP operation, two or more routers are represented as a single virtual router.Explanation: In a First Hop Redundancy Protocol like HSRP, multiple routers share a virtual MAC and virtual IP address which are presented to hosts as a single “virtual” router to use as a gateway.
Q10. What is a best practice to use before beginning an EtherChannel implementation?
- Enable each of the affected interfaces.
- Assign affected interfaces to the management VLAN.
- Shut down each of the affected interfaces.
- Assign affected interfaces to VLAN 1.
- Assign affected interfaces to an unused VLAN.
Explanation: Before configuring EtherChannel, the interfaces used should be shut down so that any incomplete configuration will not cause activity on the link.
Q11. Which statement describes an EtherChannel implementation?
- EtherChannel operates only at Layer 2.
- A trunked port can be part of an EtherChannel bundle.
- EtherChannel can support up to a maximum of ten separate links.
- PAgP cannot be used in conjunction with EtherChannel.
Explanation: Up to 16 links can be grouped in an EtherChannel by using the the PAgP or LACP protocol. EtherChannel can be configured as a Layer 2 bundle or a Layer 3 bundle. Configuring a Layer 3 bundle is beyond the scope of this course. If a trunked port is a part of the EtherChannel bundle, all ports in the bundle need to be trunk ports and the native VLAN must be the same on all of these ports. A best practice is to apply the configuration to the port channel interface. The configuration is then automatically applied to the individual ports.
Q12. Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. What are two reasons why the ping messages that are issued from Laptop0 towards Laptop1 are failing? (Choose two.)
- The two interfaces on each of the switches belong to different VLANs.
- The interface VLAN 1 is shut down on both switches.
- The channel group mode is not set correctly on the switches.
- The wrong cable types are connecting the two switches.
- The channel group should be configured as a trunk on each switch.
Explanation: Port-channel 1 needs to be configured as a trunk in order to carry data about two different VLANs. The channel group is set as auto and desirable. The SVI has not been configured on the switches, but this does not affect the creation of an EtherChannel. The use of straight-through cables between switches is not an issue when using a Cisco Catalyst 2960 switch.

Explanation: No answer description available for this question
Q16. Which three options must match in order to establish an EtherChannel between two directly connected switches? (Choose three.)
- duplex settings of the interfaces that are used for EtherChannel
- port security settings on the interfaces that used for EtherChannel
- VLAN memberships of the interfaces that are used for EtherChannel
- speed of the interfaces that are used for EtherChannel
- domain names on the switches
- port numbers that are used for the EtherChannel
Explanation: Speed and duplex settings must match for all interfaces in an EtherChannel. All interfaces in the EtherChannel must be in the same VLAN if the ports are not configured as trunks. Any ports may be used to establish an EtherChannel. Domain names and port security settings are not relevant to EtherChannel.
Q17. Which two protocols are used to implement EtherChannel? (Choose two.)
- Link Aggregation Control Protocol
- Spanning Tree Protocol
- Port Aggregation Protocol
- Cisco Discovery Protocol
- Rapid Spanning Tree Protocol
Explanation: Port Aggregation Protocol and Link Aggregation Control Protocol are used to implement EtherChannel. Spanning Tree and Rapid Spanning Tree Protocol are used to prevent switching loops. Cisco Discovery Protocol is Cisco-proprietary and is used to discovery information about adjacent Cisco devices such as model number and IP address.
Q18. In FHRP terminology, what represents a set of routers that present the illusion of a single router to hosts?
- virtual router
- forwarding router
- standby router
- default gateway
Explanation: In FHRP multiple routers are configured to work together to present to hosts a single gateway router. This single gateway router is a virtual router which has a virtual IP address that is used by hosts as a default gateway.
Q19. Which command must be used on SW2 to enable this EtherChannel?
- SW2(config-if-range)# channel-group 1 mode desirable
- SW2(config-if-range)# channel-group 1 mode auto
- SW2(config-if-range)# channel-group 1 mode passive
- SW2(config-if-range)# channel-group 1 mode active
Explanation: No answer description available for this question
Q20. An EtherChannel link using LACP was formed between two switches, S1 and S2. While verifying the configuration, which mode combination could be utilized on both switches?
- S1-on and S2-active
- S1-passive and S2-passive
- S1-on and S2-passive
- S1-passive and S2-active
Explanation: An EtherChannel link will be formed using LACP when both switches are in on mode or in active mode, or when one of them is in passive mode and the other is in active mode.
Q21. Which statement describes a characteristic of EtherChannel?
- It can bundle mixed types of 100 Mb/s and 1Gb/s Ethernet links.
- It consists of multiple parallel links between a switch and a router.
- It can combine up to a maximum of 4 physical links.
- It is made by combining multiple physical links that are seen as one link between two switches.
Explanation: An EtherChannel is formed by combining multiple (same type) Ethernet physical links so they are seen and configured as one logical link. It provides an aggregated link between two switches. Currently each EtherChannel can consist of up to eight compatibly configured Ethernet ports.
Q22. Question
Explanation: No answer description available for this question
Q23. Which statement is true regarding the use of PAgP to create EtherChannels?
- It requires more physical links than LACP does.
- It mandates that an even number of ports (2, 4, 6, etc.) be used for aggregation.
- It is Cisco proprietary.
- It increases the number of ports that are participating in spanning tree.
- It requires full duplex.
Explanation: PAgP is used to automatically aggregate multiple ports into an EtherChannel bundle, but it only works between Cisco devices. LACP can be used for the same purpose between Cisco and non-Cisco devices. PAgP must have the same duplex mode at both ends and can use two ports or more. The number of ports depends on the switch platform or module. An EtherChannel aggregated link is seen as one port by the spanning-tree algorithm.

Q25. Which nonproprietary protocol provides router redundancy for a group of routers which support IPv4 LANs?
- GLBP
- SLB
- VRRPv2
- HSRP
Explanation: The only nonproprietary FHRP used for router redundancy listed in the options is VRRPv2. HSRP and GLBP are both Cisco proprietary FHRPs. IOS SLB is a Cisco-based solution used to load balance traffic across multiple servers.
Q26. A network administrator is configuring an EtherChannel link between switches SW1 and SW2 by using the command SW1(config-if-range)# channel-group 1 mode passive. Which command must be used on SW2 to enable this EtherChannel?
- SW2(config-if-range)# channel-group 1 mode desirable
- SW2(config-if-range)# channel-group 1 mode auto
- SW2(config-if-range)# channel-group 1 mode passive
- SW2(config-if-range)# channel-group 1 mode active
Explanation: The possible combinations to establish an EtherChannel between SW1 and SW2 using LACP or
PAgP are as follows:
PAgP
on on
auto desirable
