Refer to the exhibit. Which devices exist in the failure domain when switch S3 loses power?
- PC_3 and AP_2
- PC_3 and PC_2
- S1 and S4
- S4 and PC_2
- AP_2 and AP_1
5.How can an enterprise network be designed to optimize bandwidth?
- by limiting the size of failure domains
- by organizing the network to control traffic patterns
- by installing devices with failover capabilities
- by deploying a collapsed core model
6.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?
- Redundant paths can be available without causing logical Layer 2 loops.
- Faster convergence is available for advanced routing protocols.
- Multiple physical interfaces can be combined into a single EtherChannel interface.
- Network access can be expanded to support both wired and wireless devices.
7.As the network administrator you have been asked to implement EtherChannel on the corporate network. What does this configuration consist of?
- grouping multiple physical ports to increase bandwidth between two switches
- providing redundant devices to allow traffic to flow in the event of device failure
- providing redundant links that dynamically block or forward traffic
- grouping two devices to share a virtual IP address
8.Which statement describes a characteristic of Cisco Meraki switches?
- They are cloud-managed access switches that enable virtual stacking of switches.
- They are service provider switches that aggregate traffic at the edge of the network.
- They promote infrastructure scalability, operational continuity, and transport flexibility.
- They are campus LAN switches that perform the same functions as Cisco 2960 switches.
9.In which situation would a network administrator install a Cisco Nexus Series or Cisco Catalyst 6500 Series switch to promote infrastructure scalability?
- on a service provider network to promote integrated security, and simplified management
- on a campus LAN network as access layer switches
- to enable virtual stacking of switches to provide cloud-managed access
- on a data center network to provide expansion and transport flexibility
10.Which statement describes a characteristic of Cisco Catalyst 2960 switches?
- They are best used as distribution layer switches.
- New Cisco Catalyst 2960-C switches support PoE pass-through.
- They do not support an active switched virtual interface (SVI) with IOS versions prior to 15.x.
- They are modular switches.
11.What are two benefits of extending access layer connectivity to users through a wireless medium? (Choose two.)
- decreased number of critical points of failure
- reduced costs
- increased network management options
- increased flexibility
- increased bandwidth availability
12.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 replacement?
- a modular router
- another fixed configuration router
- a Layer 3 switch
- a PoE device
13.What are two functions of a router? (Choose two.)
- It controls the flow of data via the use of Layer 2 addresses.
- It manages the VLAN database.
- It increases the size of the broadcast domain.
- It connects multiple IP networks.
- It determines the best path to send packets.
14.Immediately after a router completes its boot sequence, the network administrator wants to check the routers configuration. From privileged EXEC mode, which of the following commands can the administrator use for this purpose? (Choose two.)
- show NVRAM
- show running-config
- show version
- show flash
- show startup-config
15.What is a characteristic of in-band device management?
- It is used for initial configuration or when a network connection is unavailable.
- It is used to monitor and make configuration changes to a network device over a network connection.
- It uses a terminal emulation client.
- It uses a direct connection to a console or AUX port.
16.Mach the purpose to the related configuration item. (Not all options are used.)
