Lesson 2

A Cisco switch has four memory areas that store various files as well as the IOS. In which memory area is the bootstrap program stored?

D) ROM is correct because it is the memory type that holds the bootstrap program and the ROM monitor program.

Which of the following protocols are enabled by default on a Cisco router for external users to access?

D) The default setting is to have both Telnet and SSH disabled (that is, transport input none).

You have just completed the setup of your new Cisco 2960 switch, and you need to save your work. To save the configuration file, you would issue which of the following commands?

D) You use the copy running-config startup-config command to save the current configuration to the NVRAM. It will then be used when the device reboots or is powered on and off.

A Cisco switch has four area modules that store various files and the IOS. In which area module is the startup-configuration file stored?

A Cisco device maintains (stores) a copy of the initial (startup) configuration in the NVRAM.

VTY Line mode is part of the Line mode of operation and will be reached with the line vty 0 15 command. The command line console 0 will also reach Line mode.

A Cisco device maintains (stores) a local copy of IOS in the Flash memory.

Which of the following commands are shared between the console and Telnet for the setup of simple passwords?

B and CExplanation: B) After the configuration mode is entered, the login and password commands are the same for both modes.C) After the configuration mode is entered, the login and password commands are the same for both modes.Remediation Link: Chapter 6, Securing User Mode and Privileged Mode with Simple Passwords

Which of the following commands should be used to force the use of username/password combinations stored on the local switch for both the console and Telnet?

C) The command login local defaults the login to the local switch, and no password clears any existing passwords that may work to circumvent the local login.

Which of the following transport input commands will configure a port to support both Telnet and SSH?

Either transport input all or transport input telnet ssh will enable support for both SSH and Telnet.B) Either transport input all or transport input telnet ssh will enable support for both SSH and Telnet.

Cisco uses the term ________ to refer to a reinitialization of the software. Select one:

Explanation: A) The reload command causes a switch to reinitialize, loading the starting-config file.

What is the name used to identify a virtual NIC type of device that exists on Cisco switches to assign IP information to specific VLANs?

On most Cisco switches, there exists the concept of a switched virtual interface (SVI), which enables the user to configure IP settings for a specific VLAN.

The ________ changes dynamically when someone enters commands in configuration mode.

Only the startup-config and running-config exists; running-config is the copy currently running that gets modified as commands are executed.

The ________ stores the configuration used anytime the switch reloads Cisco IOS.

Only the startup-config and running-config exists; startup-config is the default after a restart.

Which of the following is the goal of establishing a loop-free environment?

STP creates a loop-free environment, which avoids broadcast storms by forwarding only one copy of a frame.

Which of the following commands should immediately follow interface vlan 1 when configuring IPv4 on a switch?

The IP address and mask need to be established first, so the command ip addressip-address mask should be used next.

Which of the following is the mode that is active when the CLI prompt displays hostname(config-if)#?

The Interface mode is identified by the "-if" in the prompt.

Given the following address table, which port would be used to forward a frame destined for 0200.2222.2222? Vlan Mac Address Type Ports ---- --------------- ---- ----- 1 0200.1111.1111 DYNAMIC Fa0/1 1 0200.2222.2222 DYNAMIC Fa0/2 1 0200.3333.3333 DYNAMIC Fa0/3 1 0200.4444.4444 DYNAMIC Fa0/4

The address table determines which port will transmit a frame; in this case, the destination matches the port for Fa0/2.

Which of the following commands is used to configure a switch to use DNS to resolve a name to a matching IP address?

The command ip name-server in configuration mode enables the use of Domain Name System (DNS) to resolve names to matching IP addresses.

Which of the following commands in configuration mode will enable the VLAN interface if it is not already enabled?

The command no shutdown will administratively enable an interface.

You just unpacked a brand new Cisco 2960 switch. Which ports/interfaces are ready to connect to and be used to set up the switch?

The console interface is the only interface that is open to accept commands on a brand new switch (or router).

Which of the following will occur on a network with redundant links that does NOT use STP?

The frame will loop forever, and multiple copies will generate from each redundant switch in the network, clogging the network to useful traffic.

When connecting multiple switches with redundant links, which of the following protocols helps to ensure that you will have a loop-free Ethernet network?

The function of the Spanning Tree Protocol (STP) is to provide a loop-free Ethernet network.

Which of the following commands should be done as a precursor to generating a matched public and private key for encryption?

The hostname (hostnamename) and domain name (ip domain-namename) need to be configured before generating the keys for encryption.

How many VLAN interfaces (SVI) can exist and be up on a typical Layer 2 Cisco switch at the same time?

The keyword counters in the show interface command is used to provide routing statistics for the interface.

Which of the following commands is used to initiate the configuration mode to set a password for Telnet?

The line vty 0 15 command enters the configuration mode for all 16 vty lines in Telnet.

Which command can be used to alter the default display behavior of syslog messages on a device so that they will not interrupt the output of a show command?

The logging synchronous command is used to alter the default display behavior of syslog messages on a device.

Which of the following commands is used to enable console password security using a simple password?

The login command is used to enable password security, and the password command is used to set the value.

Which of the following is a characteristic of the shared passwords used in networking?

The shared password is set by network administrators, not the individual user, so it is known by several people.

Given the following address table, which port will NOT retransmit a frame received from 0200.3333.3333? Vlan Mac Address Type Ports ---- ----------- -------- ----- 1 0200.1111.1111 DYNAMIC Fa0/1 1 0200.2222.2222 DYNAMIC Fa0/2 1 0200.3333.3333 DYNAMIC Fa0/3 1 0200.4444.4444 DYNAMIC Fa0/4

The switch will filter a frame for the port on which it is received-in this case, port Fa0/3.

Which of the following will occur when a switch encounters an unknown destination unicast frame?

The switch will treat an unknown destination unicast frame like a broadcast or multicast frame and flood it over the network.

Which of the following keywords for the show mac address-table dynamic command would be most beneficial to a network engineer troubleshooting a problem using a network topology diagram that does NOT contain MAC addresses?

The topology diagram will typically list the interfaces for the network, so the engineer can use the interface keyword to get the information needed.

Which of the following is the mode that is active when the CLI prompt displays hostname(config)#?

This is the default starting mode; no command is needed to reach this mode.

Which Cisco IOS command is used to display local interface (not server) DHCP IPv4 assignment information?

To find out information about what DHCP addresses and other information were assigned to a local interface, use the show dhcp lease command.

You are having trouble remembering part of the correct format of a command. Which of the commands would give you help on the correct format of the parameters?

To obtain access to the help available for a specific command, first type the command, a space, and then the ? mark.

Which of the following is the mode that is activated in the CLI by the command line vty 0 15?

VTY Line mode is part of the Line mode of operation and will be reached with the line vty 0 15 command. The command line console 0 will also reach Line mode.

The process of sending frames out all other interfaces, except the interface on which the frame arrived, is called ________.

When a switch receives a frame from an unknown Ethernet MAC address, it floods (flooding) the network so that the correct machine will respond.

When STP has placed a port in the blocked state, this port ________.

When an STP port is in blocking state, it can only listen to management Bridge Protocol Data Units (BPDU) but does not listen or forward any data frames.

Which of the following commands would you issue to move from the User EXEC mode to the Privileged EXEC mode?
