Question
1:
v/
Correct
Which
of
the
following
proxy
server
roles
stores
frequently
accesses
data
so
that
a
user's
request
never
has
to
leave
the
network
for
retrieval?
Firewall

Caching
Explanation
Caching
allows
frequently
accessed
data
to
be
stored
on
the
local
proxy
server
so
that
a
user's
request
never
has
to
leave
the
network
for
retrieval.
A
VPN
allows
users
to
connect
to
the
internet
anonymously.
All
the
data
is
encrypted,
and
not
even
the
ISP
can
see
the
contents
of
the
traffic.
The
Sharing
Internet
Connections
role
allows
all
devices
to
be
funneled
through
one
connection,
controlling
the
flow
of
network
traffic.
This
is
a
good
solution
for
wireless
device
connections
over
Wi-Fi.
A
firewall
is
a
security
system
on
a
network
that
acts
as
a
barrier
between
the
network
and
the
rest
of
the
internet.
A
firewall
is
configured
to
block
unwanted
access
and
traffic
that
could
cause
security
issues.

actions
would
BEST

your
criteria?
Enable
Windows
Firewall
on
each
system.
Add

remove
exceptions
to

access
based
on
time
of
day
and

server.
Configure
a
packet-filtering
firewall.
Add
rules
to

Explanation
You
should
use
a
proxy
server
to
control
internet
access
based
on
user,
time
of
day,
and
websites
visited.
You
would
configure
these
rules
on
the
proxy
server,
and
all
internet
access
requests
would
be
routed
through
the
proxy
server
using
these
rules.
You
use
a
packet-filtering
firewall,
such
as
Windows
Firewall,
to
allow
or
deny
individual
packets
based
on
characteristics
such
as
source
or
destination
address
and
port
number.
You
configure
internet
zones
to
identify
trusted
or
restricted
websites
and
to
control
the
types
of
actions
that
can
be
performed
when
going
to
those
sites.

Question
4:
v/
Correct
As
a
network
administrator
for
your
company,
you
want
to
set
up
a
network
device
that
manages
traffic
leaving
and
entering
your
network
from
the
outside.
Which
of
the
following
would
BEST
meet
your
requirements?
VPN
Content
filter
Reverse
proxy
server
=
Forward
proxy
server
Explanation
A
forward
proxy
server
manages
traffic
leaving
and
entering
your
network
from
the
outside.
A
reverse
proxy
server
is
placed
between
the
servers
and
client
machines
internally
to
monitor
traffic
between
them.
A
content
filter
is
a
role
of
a
proxy
server
that
is
designed
to
block
traffic
by
regulating
incoming
and
outgoing
connection
requests.
This
prevents
users
from
accessing
websites
they
shouldn't
have
access
to.
A
VPN
(or
website
proxy) allows
users
to
connect
to
the
internet
anonymously.
All
data
is
encrypted,
and
not
even
the
ISP
can see
the
contents
of
the
traffic.

Question
5:
v/
Correct
Two
employees
are
unable
to
access
any
websites
on
the
internet,
but
they
can
still
access
servers
on
the
local
network,
including
those
residing
on
other
subnets.
Other
employees
are
not
experiencing
the
same
problem.
Which
of
the
following
actions
would
BEST
resolve
this
issue?
Reconfigure
the
clients
to
send
all
traffic
directly
to
the
ISP,
bypassing
the
proxy
server.
Identify
the
filter
settings
on
the
proxy
server
for
specific
internet
sites.
Use
ipconfig
to
confirm
that
APIPA
has
not
assigned
an
IP
address.
Identify
the
proxy
server
name
and
port
=
.
.
number
in
Internet
Options.
Explanation
In
this
case,
you
should
identify
the
proxy
server
name
and
port
number
in
Internet
Options.
Windows
automatically
detects
and
uses
a
proxy
server
if
one
is
on
the
network.
If
the
proxy
server
is
not
detected,
you
should
manually
configure
the
proxy
settings.
Because
other
users
are
not
experiencing
the
same
problems,
the
filtering
settings
on
the
proxy
server
for
specific
internet
sites
are
probably
not
the
cause
of
the
problem.
If
you
bypass
the
proxy
server,
the
clients
are
no
longer
managed
by
the
proxy
server.
This
is
not
a
recommended
solution.
IP
addresses
assigned
by
APIPA
force
the
client
to
the
169.254.0.0
subnet.
This
would
prevent
the
client
form
accessing
internal
servers
that
use
static
IP
addresses,
especially
those
on
different
subnets.

Question
6:
v/
Correct
An
after-school
care
center
allows
children
to
browse
the
internet.
They
want
to
limit
the
websites
that
the
children
can
access.
Which
of
the
following
network
hosts
would
MOST
likely
provide
this
service?
Web
server
Print
server
DHCP
server
=
Proxy
server
Explanation
One
function
of
a
proxy
server
is
to
intercept
requests
from
a
client
browser
and
either
forward
them
on
to
the
internet
or
deny
access
to
that
request.
A
print
server
manages
network
printers
and
makes
them
available
to
computers
throughout
the
network.
Print
jobs
are
sent
to
the
print
server
instead
of
directly
to
the
printer.
A
web
server
offers
web
pages
to
clients.
Many
organizations
have
their
own
web
server
that
is
accessible
from
the
internet
or
from
the
internal
network.
A
DHCP
server
leases
IP
addresses
to
client
computers
when
they
first
connect
to
the
network.

Question
7:
v/
Correct
Which
of
the
following
functions
are
performed
by
proxy
servers?
(Select
two.)
Block
employees
from
accessing
certain
>
.
websites.
Store
client
files.
Filter
unwanted
email.
>
Cache
web
pages.
Block
unwanted
packets
from
entering
your
private
network.
Explanation
A
proxy,
or
proxy
server,
stands
between
client
computers
and
web
servers.
You
can
use
a
proxy
server
to
prevent
access
to
specific
websites
or
to
cache
(save)
frequently
used
web
pages.
When
a
proxy
receives
a
request
from
the
client,
the
proxy
checks
to
verify
that
the
client
is
allowed
access
to
the
website.
If
they
are,
the
proxy
then
checks
its
cache
to
see
if
the
requested
page
is
there.
If
the
page
is
already
cached,
the
proxy
server
fulfills
the
request
by
displaying
the
requested
page
from
the
cache
rather
than
retrieving
it
from
the
internet.
Receiving
a
web
page
from
a
local
proxy
server
is
much
faster
than
downloading
the
page
from
the
internet.

Question
8:
v/
Correct
You
connect
your
computer
to
a
wireless
network
available
at
the
local
library.
You
find
that
you
cannot
access
several
websites
on
the
internet.
Which
of
the
following
is
the
MOST
likely
cause
of
this
problem?
A
firewall
is
blocking
ports
80
and
443.
=
A
proxy
server
is
filtering
access
to
websites.
The
router
has
not
been
configured
to
perform
port
forwarding.
Port
triggering
is
redirecting
traffic
to
the
wrong
IP
address.
Explanation
A
proxy
server
can
block
internet
access
based
on
website
or
URL.
Many
schools
and
public
networks
use
proxy
servers
to
prevent
access
to
websites
with
objectionable
content.
Ports
80
and
443
are
used
by
HTTP
to
retrieve
all
web
content.
If
a
firewall
were
blocking
these
ports,
access
would
be
denied
to
all
websites.
Port
forwarding
directs
incoming
connections
to
a
host
on
the
private
network.
Port
triggering
dynamically
opens
firewall
ports
based
on
applications
that
initiate
contact
from
the
private
network.
