Worksheet time: 14mins
How many broadcast domain and collision domain exist in the topology?
12 Broadcast, 11 Collision
12 Collision, 11 Broadcast
5 Broadcast, 10 Collision
5 Collision, 10 Broadcast
Which type of VLAN is used to designate which traffic is untagged when crossing a trunk port?
Data
Default
Native
Management
Refer to the Figure. A network administrator has connected two switches together using EtherChannel technology. If STP is running, what will be the end result?
The switches will load balance and utilize both EtherChannels to forward packets.
Both port channels will shutdown.
The resulting loop will create a broadcast storm.
STP will block one of the redundant links.
What protocol or technology disables redundant paths to eliminate Layer 2 loops?
VLAN Trunking Protocol (VTP)
Spanning Tree Protocol (STP)
EtherChannel
Dynamic Trunking Protocol (DTP)
Refer to the figure. All the displayed switches are Cisco 2960 switches with the same default priority and operating at the same bandwidth. Which three ports will be STP designated ports? (Choose three.)
fa0/9
fa0/10
fa0/11
fa0/21
Which command will start the process to bundle two physical interfaces to create an EtherChannel group via LACP?
interface port-channel 2
channel-group 1 mode desirable
interface range GigabitEthernet 0/4 – 5
channel-group 2 mode auto
What will be the third step of Spanning Tree Protocol (STP)?
Block the unwanted port
Elect root port
Elect root bridge
Get the designated port
Refer to the Figure. Which trunk link will not forward any traffic after the root bridge election process is complete?
Trunk 1
Trunk 2
Trunk 3
Trunk 4
How to ensure the uniqueness of IPv6 Global Unicast Address?
EUI-64 Process
DAD process
Operating System Random Generate Number
SLAAC method
Which command is used to verify the status of EtherChannel on a switch?
show etherchannel summary
show interfaces status
show spanning-tree
show vlan brief
In a network using Rapid Spanning Tree Protocol (RSTP), what happens when a port transitions from listening to learning state?
The port starts forwarding traffic immediately
The port begins to learn MAC addresses
The port is disabled temporarily
The port will block all traffic
What is the role of the root bridge in the Spanning Tree Protocol (STP)?
To manage VLAN assignments
To act as a central point for all STP calculations
To forward all traffic in the network
To provide redundancy for Layer 3 routing
In a network using STP, what happens when a new switch is added to the topology?
It automatically becomes the root bridge
STP recalculates the topology to include the new switch
All ports on the new switch are enabled immediately
It will block all traffic until configured
Which command is used to configure a switch port to participate in an EtherChannel using PAgP?
channel-group 1 mode on
channel-group 1 mode desirable
interface port-channel 1
switchport mode trunk
What are two requirements to be able to configure an EtherChannel between two switches? (Choose two.)
All the interfaces need to work at the same speed.
All interfaces need to be assigned to different VLANs.
Different allowed ranges of VLANs must exist on each end.
All the interfaces need to be working in the same duplex mode.
The interfaces that are involved need to be contiguous on the switch.
A network administrator configured an EtherChannel link with three interfaces between two switches. What is the result if one of the three interfaces is down?
The remaining two interfaces continue to load balance traffic.
The remaining two interfaces become separate links between the two switches.
One interface becomes an active link for data traffic and the other becomes a backup link.
The EtherChannel fails.
Which of the following is an indication that a Windows computer did not receive an IPv4 address from a DHCP server?
The computer cannot ping 127.0.0.1
Windows displays a DHCP timeout message.
The computer receives an IP address from the 169.254.0.0/16 range.
The computer cannot ping other devices within the same 169.254.0.0/16 network range.
What are the four steps in the DHCPv4 lease process?
DHCP Acknowledgment, DHCP Request, DHCP Discover, DHCP Offer
DHCP Discover, DHCP Offer, DHCP Request, DHCP Acknowledgment
DHCP Offer, DHCP Discover, DHCP Acknowledgment, DHCP Request
DHCP Request, DHCP Acknowledgment, DHCP Offer, DHCP Discover
What is the purpose of a Cisco IOS helper address in DHCPv4 relay?
To forward DHCPDISCOVER messages to the DHCPv4 server
To configure a DHCPv4 pool
To verify DHCPv4 configuration
To exclude IP addresses from being assigned
Which of the following Cisco protocols provides a Cisco proprietary First Hop Redundancy solution?
VRRP
HSRP
GLBP
FHRP
In VRRP, which router is responsible for forwarding packets sent to the virtual IP address?
The Backup Router
The Master Router
The Standby Router
The Active Virtual Gateway (AVG)
