QuestionAnswer
Which tasks can be accomplished by using the command history feature? (Choose two.) Set the command history buffer size. Recall previously entered commands.
What must an administrator have in order to reset a lost password on a router? physical access to the router
What is the first action in the boot sequence when a switch is powered on? load a power-on self-test program
When configuring a switch for SSH access, what other command that is associated with the login local command is required to be entered on the switch? username username secret secret
Which command displays information about the auto-MDIX setting for a specific interface?​ show controllers
If one end of an Ethernet connection is configured for full duplex and the other end of the connection is configured for half duplex, where would late collisions be observed? on the half-duplex end of the connection
Which command is used to set the BOOT environment variable that defines where to find the IOS boot system
What does a switch use to locate and load the IOS image? BOOT environment variable
Which protocol adds security to remote connections? SSH
What is a characteristic of an IPv4 loopback interface on a Cisco IOS router?​ It is a logical interface internal to the router.
What is the minimum Ethernet frame size that will not be discarded by the receiver as a runt frame? 64 bytes
After which step of the switch bootup sequence is the boot loader executed? after POST execution
Which impact does adding a Layer 2 switch have on a network? an increase in the size of the broadcast domain
Which characteristic describes cut-through switching? Frames are forwarded without any error checking.
What is the significant difference between a hub and a Layer 2 LAN switch? A hub extends a collision domain, and a switch divides collision domains.
Which statement is correct about Ethernet switch frame forwarding decisions? Frame forwarding decisions are based on MAC address and port mappings in the CAM table.
How do switch buffers affect network performance? They store frames received, thus preventing premature frame discarding when network congestion occurs.
Which switch characteristic helps keep traffic local and alleviates network congestion? high port density
Which switch component reduces the amount of packet handling time inside the switch? ASIC
What information is added to the switch table from incoming frames? source MAC address and incoming port number
Which switching method ensures that the incoming frame is error-free before forwarding? store-and-forward
Under which two occasions should an administrator disable DTP while managing a local area network? (Choose two.) when connecting a Cisco switch to a non-Cisco switch on links that should not be trunking
Which two characteristics describe the native VLAN? (Choose two.) The native VLAN traffic will be untagged across the trunk link. The native VLAN provides a common identifier to both ends of a trunk.
On a switch that is configured with multiple VLANs, which command will remove only VLAN 100 from the switch? Switch(config)# no vlan 100
A network contains multiple VLANs spanning multiple switches. What happens when a device in VLAN 20 sends a broadcast Ethernet frame? Only devices in VLAN 20 see the frame.
What happens to switch ports after the VLAN to which they are assigned is deleted? The ports stop communicating with the attached devices.
Port Fa0/11 on a switch is assigned to VLAN 30. If the command no switchport access vlan 30 is entered on the Fa0/11 interface, what will happen? Port Fa0/11 will be returned to VLAN 1.
Which command displays the encapsulation type, the voice VLAN ID, and the access mode VLAN for the Fa0/1 interface? show interfaces Fa0/1 switchport
Which four steps are needed to configure a voice VLAN on a switch port? (Choose four). Assign the voice VLAN to the switch port. Ensure that voice traffic is trusted and tagged with a CoS priority value. Add a voice VLAN. Configure the switch port in access mode.
A high school uses VLAN15 for the laboratory network and VLAN30 for the faculty network. What is required to enable communication between these two VLANs while using the router-on-a-stick approach? A switch with a port that is configured as a trunk is needed when connecting to the router.
When routing a large number of VLANs, what are two disadvantages of using the router-on-a-stick inter-VLAN routing method rather than the multilayer switch inter-VLAN routing method? (Choose two.) A dedicated router is required. Multiple subinterfaces may impact the traffic flow speed.
What is a characteristic of a routed port on a Layer 3 switch? It is not assigned to a VLAN.
A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw(config-if)# mdix auto command? It automatically adjusts the port to allow device connections to use either a straight-through or a crossover cable.
A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw(config-if)# ip address 172.18.33.88 255.255.255.0 command? It applies an IPv4 address to the virtual interface.
A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw# configure terminal command? It enters the global configuration mode.
A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw# configure terminal command? It enters the global configuration mode.
A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw(config-if)# shutdown command? It disables a virtual or physical switch interface.
A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw(config-if)# shutdown command? It disables a virtual or physical switch interface.
A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw(config-if)# ipv6 address 2001:db8:a2b4:88::1/64 command? It applies an IPv6 address to the virtual interface.
A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw(config-if)# exit command? It returns to global configuration mode.
A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw> enable command? It enters privileged mode.
A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw(config-if)# duplex full command? It allows data to flow in both directions at the same time on the interface.
What type of VLAN should not carry voice and network management traffic? data VLAN
What type of VLAN is designed to reserve bandwidth to ensure IP Phone quality? voice VLAN
What type of VLAN is initially the management VLAN? default VLAN
What type of VLAN is designed to have a delay of less than 150 ms across the network? voice VLAN
