Question 7

Question
A network administrator is planning redundant devices and cabling in a switched network to support high availability. Which benefit will implementing the Spanning Tree Protocol provide to this design?
Answer
  • Redundant paths can be available without causing logical Layer 2 loops.
  • Multiple physical interfaces can be combined into a single EtherChannel interface
  • Faster convergence is available for advanced routing protocols
  • Network access can be expanded to support both wired and wireless devices

Question 8

Question
What are two benefits of extending access layer connectivity to users through a wireless medium?(Choose two.)
Answer
  • increased network management options
  • reduced costs
  • increased flexibility
  • increased bandwidth availability
  • decreased number of critical points of failure

Question 9

Question
As the network administrator you have been asked to implement EtherChannel on the corporate network. What does this configuration consist of?
Answer
  • grouping multiple physical ports to increase bandwidth between two switches
  • providing redundant links that dynamically block or forward traffic
  • grouping two devices to share a virtual IP address
  • providing redundant devices to allow traffic to flow in the event of device failure

Question 10

Question
Which statement describes a characteristic of Cisco Meraki switches?
Answer
  • They are service provider switches that aggregate traffic at the edge of the network
  • They are cloud-managed access switches that enable virtual stacking of switches.
  • They are campus LAN switches that perform the same functions as Cisco 2960 switches
  • They promote infrastructure scalability, operational continuity, and transport flexibility

Question 11

Question
In which situation would a network administrator install a Cisco Nexus Series or Cisco Catalyst 6500 Series switch to promote infrastructure scalability?
Answer
  • on a service provider network to promote integrated security, and simplified management
  • on a data center network to provide expansion and transport flexibility
  • to enable virtual stacking of switches to provide cloud-managed access
  • on a campus LAN network as access layer switches

Question 12

Question
Which statement describes a characteristic of Cisco Catalyst 2960 switches?
Answer
  • New Cisco Catalyst 2960-C switches support PoE pass-through
  • They are best used as distribution layer switches
  • They do not support an active switched virtual interface (SVI) with IOS versions prior to 15.x.
  • They are modular switches

Question 13

Question
What is the function of ASICs in a multilayer switch?
Answer
  • They streamline forwarding of IP packets in a multilayer switch by bypassing the CPU.
  • They aggregate multiple physical switch ports into a single logical port.
  • They prevent Layer 2 loops by disabling redundant links between switches.
  • They provide power to devices such as IP phones and wireless access points through Ethernet ports.

Question 14

Question
What is the function of PoE pass-through?
Answer
  • allows switches, phones, and wireless access points to receive power over existing Ethernet cables from an upstream switch
  • allows multiple physical switch ports to be aggregated together and act as a single logical link to increase bandwidth on trunk links
  • allows a switch to disable redundant Layer 2 paths in the topology to prevent Layer 2 loops
  • allows a multilayer switch to forward IP packets at a rate close to that of Layer 2 switching by bypassing the CPU

Question 15

Question
What term is used to express the thickness or height of a switch?
Answer
  • domain size
  • rack unit
  • port density
  • module size

Question 16

Question
A network engineer is reviewing a network design that uses a fixed configuration enterprise router that supports both LAN and WAN connections. However, the engineer realizes that the router does not have enough interfaces to support growth and network expansion. Which type of device should be used as a replacement?
Answer
  • a PoE device
  • another fixed configuration router
  • a modular router
  • a Layer 3 switch

Question 17

Question
What are two functions of a router?(Choose two.)
Answer
  • It controls the flow of data via the use of Layer 2 addresses.
  • It increases the size of the broadcast domain.
  • It manages the VLAN database.
  • It determines the best path to send packets
  • It connects multiple IP networks.

Question 18

Question
Which two requirements must always be met to use in-band management to configure a network device? (Choose two.)
Answer
  • at least one network interface that is connected and operational
  • a terminal emulation client
  • a direct connection to the console port
  • a direct connection to the auxiliary port
  • Telnet, SSH, or HTTP access to the device

Question 19

  • show version
  • show running-config

Question 20

Question
What are two ways to access a Cisco switch for out-of-band management? (Choose two.)

  • a connection that uses HTTP
  • a connection that uses the console port
  • a connection that uses Telnet
  • a connection that uses SSH

Question 21

Question

Answer
  • to display router ID and other information about OSPF neighbors
  • to display device ID and other information about directly connected Cisco devices
  • to display routing table and other information about directly connected Cisco devices
  • to display line status and other information about directly connected Cisco devices
