Which feature of a firewall allows an organization to use private non-routable
networks while enabling communication to the internet? - ANSWER ✔ Port
Address Translation (PAT)
What is the meaning of "state" when referring to stateful inspection in firewalls? -
ANSWER ✔ It refers to the connection state of a conversation between two
computers.
Which type of port has access to all VLANs by default in a traditional layer 2
switch? - ANSWER ✔ Trunk
A company provides access to employees' tax and personal information via a
public-facing web portal.What should the company implement to encrypt
employees' web access to this information? - ANSWER ✔ Transport Layer
Security (TLS)
, What is end-to-end encryption? - ANSWER ✔ Data is encrypted on the sender's
system and only the recipient is able to decrypt it.
Which phrase describes unencrypted data? - ANSWER ✔ clear
A user is mistakenly granted access to customer accounts not required for his
duties.Which component of the AAA model is violated? - ANSWER ✔
Authorization
It is a network of users that share computer resources in a limited area. - ANSWER
✔ LAN
Local Area Network - ANSWER ✔ LAN
How are Local Area Networks defined? - ANSWER ✔ In terms of protocol and
the topology used for accessing the network.
A set of rules established for users to exchange information - ANSWER ✔
Protocol
The network architecture used to interconnect the networking equipment. -
ANSWER ✔ Topology
What are the most common topologies for LANs? - ANSWER ✔ Ring, Bus, and
Star
Uses a token that is placed in the data channel and circulates around the ring. -
ANSWER ✔ Token Ring topology
,A deterministic network - ANSWER ✔ Token Ring Topology
Each station connected to the network ensures access for transmission of its
messages at regular or fixed time intervals - ANSWER ✔ Deterministic
What are the disadvantages of the Token Ring system? - ANSWER ✔ 1. If an
error changes the token pattern, it can cause the token to stop circulating.
What is a disadvantage of the Token Ring system from the troubleshooting and
maintenance? - ANSWER ✔ The token ring path must be temporarily broken or
interrupted if a computer or any device on the network is to be removed or added
to the network.
What is a solution to the troubleshooting and maintenance disadvantages of the
Token Ring system? - ANSWER ✔ Connect each computer or device on the
network to a central token ring hub.
A device that manages the passing of the token instead of relying on individual
computers to pass it. - ANSWER ✔ Token ring hub
How does the token ring hub improve the network? - ANSWER ✔ It improves the
reliability of the network.
Topology whereas the computers share the media or coaxial cable for data
transmission. - ANSWER ✔ Bus topology
, The coaxial cable that is looped through each networking device to transmit data
in a bus topology - ANSWER ✔ ThinNet
In this topology, all devices on the network can see each other's data traffic. -
ANSWER ✔ Bus topology
Topology whereas each computer must wait for pauses in transmission or until the
transmission from one device is complete before initiating a new transmission onto
the network. - ANSWER ✔ Bus topology
What are the disadvantages of a bus topology? - ANSWER ✔ "1. Data can be
corrupted if ore than one device on the network transmits at the same time and will
have to be resubmitted.
2. The use of the shared coaxial cable prevents data transmission from being very
bandwidth-efficient."
Which topology is seldomly used in modern networks? - ANSWER ✔ Bus
topology
What is the most common topology used in today's LANs? - ANSWER ✔ Star
topology
Topology that uses twisted-pair cables with modular plugs to connect computers
and other networking devices. - ANSWER ✔ Star topology
Topology whereas each device is connected to a switch or hub - ANSWER ✔ Star
