Which devices exist in the failure domain when switch S3 loses power? A failure domain is the area of a network that is impacted when a critical device such as switch S3 has a failure or experiences problems. As the network administrator you have been asked to implement EtherChannel on the corporate network.

What does this configuration consist of? Which design feature will limit the size of a failure domain in an enterprise network? In order to best limit the of a failure domain, routers or multilayer switches can be deployed in pairs.

The failure of a single device should not cause the network to go down. Installing redundant power supplies may protect a single device from a power failure, but if that device suffers from another type of problem, a redundant device would have been a better solution. Purchasing enterprise equipment that handles large flows of traffic will not provide extra reliability in times of an outage.

If a collapsed core design is used, the core and distribution are collapsed into a single device, increasing the chance of a devastating outage. 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? With the implementation of redundant devices and links, redundant paths will exist in the network. STP is not required to combine multiple physical interfaces into a single EtherChannel interface.

STP does not provide faster convergence or an expanded network that uses wired or wireless connectivity. What are two benefits of extending access layer connectivity to users through a wireless medium?

CCNA 1 Chapter 3

Wireless connectivity at the access layer provides increased flexibility, reduced costs, and the ability to grow and adapt to changing business requirements. Utilizing wireless routers and access points can provide an increase in the number of central points of failure.

Wireless routers and access points will not provide an increase in bandwidth availability. Which two features of enterprise class equipment assists an enterprise network in maintaining Enterprise class equipment is designed with features such as redundant power supplies and failover capabilities. A failure domain is an area of a network that is impacted when a critical device fails.

A collapsed core is a two-tier hierarchical design where the core and distribution layers are collapsed into a single layer. This reduces cost and complexity but does not provide redundancy and uptime.

A network technician needs to connect a PC to a Cisco network device for initial configuration. What is required to perform this device configuration? Because the device needs to be initially configured, a network connection is unavailable yet on this device, hence the need for an out-of-band management method.

A configuration that uses out-of-band management requires a direct connection to a console or AUX port, and a terminal emulation client. What network design would contain the scope of disruptions on a network should a failure occur? One way to contain the impact of a failure on the network is to implement redundancy. One way this is accomplished is by deploying redundant distribution layer switches and dividing the access layer switch connections between the redundant distribution layer switches.

This creates what is called a switch block. Failures in a switch block are contained to that block and do not bring down the whole network. What are three access layer switch features that are considered when designing a network? Choose three. The port density of a switch the number of ports available on a single switch , forwarding rate how much data the switch can process per second , and Power over Ethernet the ability of the switch to deliver power to a device over the existing Ethernet cabling are access layer switch features to be considered when designing a network.

Failover capability, speed of convergence, and broadcast traffic containment are distribution layer features. Routers connect multiple networks in an organization to provide interconnections among them.

They perform the task by using the network portion of the destination IP address to determine the best path to send packets to their destination. What capability is provided by the use of application-specific integrated circuits in Cisco multilayer switches? Application-specific integrated circuits ASICs increase the forwarding speed of a switch by allowing packets to bypass the CPU for processing.

The Cisco Meraki cloud-managed access switches enable virtual stacking of switches. They monitor and configure thousands of switch ports over the web, without the intervention of onsite IT staff. A network engineer is reviewing a network design that uses a fixed configuration enterprise router that supports both LAN and WAN connections.

Chapter 11: Managing a Secure Network

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? Modular routers provide multiple slots that allow a network designer to change or increase the interfaces that exist on the router. A Layer 3 switch may increase the number of ports available on a router, but will not provide WAN connectivity.

The PoE capability of a device is not related to the number of ports it has. Using another fixed configuration router will not provide the flexibility to adapt to future growth that using a modular router will provide. In which situation would a network administrator install a Cisco Nexus Series or Cisco Catalyst Series switch to promote infrastructure scalability?

Cisco Nexus Series switches are employed on data centers to promote infrastructure scalability, operational continuity, and transport flexibility. They also provide secure multitenant services by adding virtualization intelligence technology to the data center network.

They are commonly used as access layer switches and they are fixed configuration switches. Which command was issued on a Cisco switch that resulted in the exhibited output? The show port-security address command displays all secure MAC addresses configured on all switch interfaces.

The show vlan summary command displays the count of all configured VLANs. In-band device management is used to monitor and make configuration changes to a network device over a network connection. Configuration using in-band management requires at least one network interface on the device to be connected and to be operational, and it requires the use of Telnet, SSH, or HTTP to access the device.
