CCNA 1 Final Exam Study Guidecharacteristics of fault tolerant network Correct Answer: Redundancy
Qos mechanisms for priorities Correct Answer: With a QoS policy in place, the router can manage the
flow of data and voice traffic, giving priority to voice communications if the network experiences
congestion.
Benefits of using cloud computing Correct Answer: can be accessed from anywhere, less space,
cheaper, lower overhead
function of the shell in an OS Correct Answer: to act as an intermediary between user and OS through
GUI or CLI
SSH Correct Answer: Secure Shell (SSH) - SSH is a method for remotely establishing a secure CLI
connection through a virtual interface, over a network. Unlike a console connection, SSH connections
require active networking services on the device including an active interface configured with an
address.
SSH is the recommended method for remote management because it provides a secure connection. SSH
provides encrypted password authentication and transport of session data. This keeps the user ID,
password, and the details of the management session private. Most versions of Cisco IOS include an SSH
server and an SSH client that can be used to establish SSH sessions with other devices.
modes of operation Correct Answer: User EXEC Mode ">" This mode has limited capabilities but is
useful for basic operations. It allows only a limited number of basic monitoring commands but does not
allow the execution of any commands that might change the configuration of the device. The user EXEC
mode is identified by the CLI prompt that ends with the > symbol.
Privileged EXEC Mode "#" To execute configuration commands, a network administrator must access
privileged EXEC mode. Higher configuration modes, like global configuration mode, can only be reached
from privileged EXEC mode. The privileged EXEC mode can be identified by the prompt ending with the #
symbol.
Ctrl-Shft-6 key command Correct Answer: All purpose break sequence. used to abort DNS lookups,
traceroutes and pings.
interface VLAN1 Correct Answer: Cisco IOS Layer 2 switches have physical ports for devices to connect.
These ports do not support Layer 3 IP addresses. Therefore, switches have one or more switch virtual
interfaces (SVIs). These are virtual interfaces because there is no physical hardware on the device
associated with it. An SVI is created in software.
The virtual interface provides a means to remotely manage a switch over a network using IPv4. Each
switch comes with one SVI appearing in the default configuration "out-of-the-box." The default SVI is
interface VLAN1.
TCP - Layer 4 protocol, responsibilities in the network communication process Correct Answer:
