A network administrator enters the following command sequence on a Cisco 3560 switch. What is the purpose of these commands?
Switch(config)# interface gigabitethernet 0/1
Switch(config-if)# no switchport
to make the Gi0/1 port a routed port
Which type of VLAN is identified by a VLAN ID between 1006 and 4094 and not contained in updates of switches participating in a VTP domain?
extended
Which sentence correctly describes the SVI inter-VLAN routing method?
An SVI is needed for each VLAN.
Which switchport mode puts the interface into permanent nontrunking ?
switchport mode dynamic auto
Which feature could be used in a network design to increase the bandwidth by combining multiple physical links into a single logical link?
EtherChannel
Which technology is required when switched networks are designed to include redundant links?
Spanning Tree Protocol
Which type of router would an enterprise use to allow customers to access content anytime and anyplace, regardless of whether they are at home or work?
network edge routers
An administrator is investigating a failure on a trunk link between a Cisco switch and a switch from another vendor. After a few show commands, the administrator notices that the the switches are not negotiating a trunk. What is a probable cause for this issue?
Switches from other vendors do not support DTP.
What is the purpose of VTP?
It provides centralized management of VLANs in a multi-switch environment.
What is the term that is used for the area of a network that is affected when a device or network service experiences problems?
failure domain
Which network design solution will best extend access layer connectivity to host devices?
implementing wireless connectivity
What is a characteristic of out-of-band device management?
It requires a terminal emulation client.
Which switchport mode Puts the interface into permanent trunking mode and negotiates
to convert the neighboring link into a trunk link?
switchport mode trunk
What is the function of PoE pass-through?
allows switches, phones, and wireless access points to receive power over existing Ethernet cables from an upstream switch
How much traffic is a 48-port gigabit switch capable of switching when operating at full wire speed?
48 Gb/s, by providing full bandwidth to each port
Which combination of DTP modes set on adjacent switches will cause the link to become an access link instead of a trunk link?
dynamic auto - dynamic auto
Which scalable method must be implemented in order to provide inter-VLAN routing on a switched network with more than 1000 VLANs?
routing traffic internally to a Layer 3 switch device
Which switchport mode makes the interface able to convert the link to a trunk
link?
switchport mode access
A company has deployed four 48-port access layer switches to a switch block. For redundancy each access layer switch will connect to two distribution layer
switches. Additionally, link aggregation will be used to combine 10 Gbps interfaces to form 20 Gbps trunk links from the access layer switches to the distribution layer switches. How many switch ports on the access layer switches will be available in the switch block to support end devices?
176
A PC is to access a web server on another network. Which inter-VLAN method will provide the highest bandwidth at Layer 3 and also provide a default gateway for the PC?
multilayer switch with routing enabled
