Networking Ch 2 Review

What command can be used on a Windows PC to see the IP configuration of that computer?

• ping
• show interfaces
• show ip interface brief
• ipconfig

While trying to solve a network issue, a technician made multiple changes to the current router configuration file. The changes did not solve the problem and were not saved. What action can the technician take to discard the changes and work with the file in NVRAM?

• Issue the reload command without saving the running configuration.
• Close and reopen the terminal emulation software.
• Delete the vlan.dat file and reboot the device.
• Issue the copy startup-config running-config command.

What criterion must be followed in the design of an IPv4 addressing scheme for end devices?

• Each local host should be assigned an IP address with a unique network component.
• Each IP address must match the address that is assigned to the host by DNS.
• Each IP address must be unique within the local network.
• Each IP address needs to be compatible with the MAC address.

A switch was configured as shown. A ping to the default gateway was issued, but the ping was not successful. Other switches in the same network can ping this gateway. What is a possible reason for this?

• The ip default-gateway command has to be issued in the VLAN interface configuration mode.
• The VLAN IP address and the default gateway IP address are not in the same network.
• The no shutdown command was not issued for VLAN 1.
• The local DNS server is not functioning correctly.

Which interface allows remote management of a Layer 2 switch?

• the switch virtual interface
• the console port interface
• the AUX interface

A network administrator needs to keep the user ID, password, and session contents private when establishing remote CLI connectivity with a switch to manage it. Which access method should be chosen?

• AUX
• SSH
• Console
• Telnet

Why is it important to configure a hostname on a device?

• to allow local access to the device through the console port
• a Cisco router or switch only begins to operate when its hostname is set
• to identify the device during remote access (SSH or telnet)
• a hostname must be configured before any other parameters

• Ethernet interfaces, console interfaces, user exec mode
• privileged EXEC mode, VTY interface, console interface
• router configuration mode, user exec mode, VTY interfaces

What does the Ctrl+Z key do?

• Completes abbreviated commands and parameters
• Returns directly to the privileged EXEC mode
• Scrolls backwards through previously entered commands
• Cancels any command currently being entered and returns directly to privileged EXEC mode
