CCNA2 v7 SRWE – Modules 1 – 4

Which tasks can be accomplished by using the command history feature? (Choose two.)

• View a list of commands entered in a previous session.

• Recall up to 15 command lines by default.

• Set the command history buffer size.

• Recall previously entered commands.

• Save command lines in a log file for future reference.

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

• when a neighbor switch uses a DTP mode of dynamic auto

• when a neighbor switch uses a DTP mode of dynamic desirable

• on links that should not be trunking

• on links that should dynamically attempt trunking

Which two characteristics describe the native VLAN? (Choose two.)

• Designed to carry traffic that is generated by users, this type of VLAN is also known as the default VLAN.

• The native VLAN traffic will be untagged across the trunk link.

• This VLAN is necessary for remote management of a switch.

• High priority traffic, such as voice traffic, uses the native VLAN.

• The native VLAN provides a common identifier to both ends of a trunk.

37. Which four steps are needed to configure a voice VLAN on a switch port? (Choose four).

• Ensure that voice traffic is trusted and tagged with a CoS priority value.

• Activate spanning-tree PortFast on the interface.

• Add a voice VLAN.

• Assign the voice VLAN to the switch port.

• Configure the interface as an IEEE 802.1Q trunk.

42. 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.)

• Multiple SVIs are needed.

• A dedicated router is required.

• Router-on-a-stick requires subinterfaces to be configured on the same subnets.

• Router-on-a-stick requires multiple physical interfaces on a router.

• Multiple subinterfaces may impact the traffic flow speed.

43. Refer to the exhibit. A network administrator is verifying the configuration of inter-VLAN routing. Users complain that PCs on different VLANs cannot communicate. Based on the output, what are two configuration errors on switch interface Gi1/1? (Choose two.)

• Gi1/1 is in the default VLAN.

• Voice VLAN is not assigned to Gi1/1.

• Gi1/1 is configured as trunk mode.

• Negotiation of trunking is turned on on Gi1/1.

• The trunking encapsulation protocol is configured wrong.

Which command is used to set the BOOT environment variable that defines where to find the IOS image file on a switch?

• config-register

• boot system

• boot loader

• confreg

44. Refer to the exhibit. A network administrator is verifying the configuration of inter-VLAN routing. Users complain that PC2 cannot communicate with PC1. Based on the output, what is the possible cause of the problem?

• Gi0/0 is not configured as a trunk port.

• The command interface GigabitEthernet0/0.5 was entered incorrectly.

• There is no IP address configured on the interface Gi0/0.

• The no shutdown command is not entered on subinterfaces.

• The encapsulation dot1Q 5 command contains the wrong VLAN.

After which step of the switch bootup sequence is the boot loader executed?

• after CPU initialization

• after IOS localization

• after flash file system initialization

• after POST execution

What is the first action in the boot sequence when a switch is powered on?

• load the default Cisco IOS software

• load boot loader software

• low-level CPU initialization

• load a power-on self-test program
