As the network administrator you have been asked to implement EtherChannel on the corporate network. What does this configuration consist of?
providing redundant links that dynamically block or forward traffic
grouping multiple physical ports to increase bandwidth between two switches
grouping two devices to share a virtual IP address
providing redundant devices to allow traffic to flow in the event of device failure
What is a definition of a two-tier LAN network design?
access and core layers collapsed into one tier, and the distribution layer on a separate tier
access and distribution layers collapsed into one tier, and the core layer on a separate tier
distribution and core layers collapsed into one tier, and the access layer on a separate tier
access, distribution, and core layers collapsed into one tier, with a separate backbone layer
What are the three layers of the switch hierarchical design model? (Choose three.)
access
distribution
data link
core
network access
What network design would contain the scope of disruptions on a network should a failure occur?
the installation of only enterprise class equipment throughout the network
the configuration of all access layer devices to share a single gateway
the reduction in the number of redundant devices and connections in the network core
the deployment of distribution layer switches in pairs and the division of access layer switch connections between them
Which action should be taken when planning for redundancy on a hierarchical network design?
immediately replace a non-functioning module, service or device on a network
continually purchase backup equipment for the network
implement STP portfast between the switches on the network
add alternate physical paths for data to traverse the network
Refer to the exhibit. Which devices exist in the failure domain when switch S3 loses power?
S4 and PC_2
PC_3 and AP_2
AP_2 and AP_1
PC_3 and PC_2
S1 and S4
What are two benefits of extending access layer connectivity to users through a wireless medium? (Choose two.)
increased flexibility
decreased number of critical points of failure
reduced costs
increased bandwidth availability
increased network management options
A network designer is considering whether to implement a switch block on the company network. What is the primary advantage of deploying a switch block?
A single core router provides all the routing between VLANs.
The failure of a switch block will not impact all end users.
This is a security feature that is available on all new Catalyst switches.
This is network application software that prevents the failure of a single network device.
What is a basic function of the Cisco Borderless Architecture access layer?
aggregates Layer 2 broadcast domains
aggregates Layer 3 routing boundaries
provides access to the user
provides fault isolation
Which characteristic would most influence a network design engineer to select a multilayer switch over a Layer 2 switch?
ability to build a routing table
ability to aggregate multiple ports for maximum data throughput
ability to provide power to directly-attached devices and the switch itself
ability to have multiple forwarding paths through the switched network based on VLAN number(s)
Allows intelligent traffic load sharing by using all network resources
