Question 10

Answer 13

3

Question 14

Answer 14

1, 6 and 11

Question 15

**True or False: **5Ghz has more clean channels to work with with hardly any signal overlap due to reduced range

Answer 15

True

Question 16

True or False: A firewall allows everything by default and denies by exception

Answer 16

False. A router does this

Question 17

**True or False: **A firewall denies everything by default and allows by exception

Answer 17

True

Question 18

Why would you put a firewall into transparent mode?

Answer 18

To put a firewall between two switches inside your network and not break up the network. You might do this to inspect traffic inside your internal network

Question 19

What is a more common mode for firewalls?

Answer 19

Routed. Sits at the edge of the network and divides networks up

Question 20

True or False: Stateful filtering means that by default the firewall allows traffic to move from a lower security zone to a higher security zone but it does not allow the opposite.

Answer 20

False. Stateful filtering allows traffic to move from a higher security zone to a lower security zone but does not allow the opposite

Question 21

Give an example of stateful filtering

Answer 21

A website cannot just reach out and talk to your internal network without being invited (lower security zone to higher security zone). However, it can respond back if the network initiated the contact (higher security zone to lower security zone)

Question 22

True or False: CUCM is an IP based PBX

Answer 22

True

Question 23

True or False: Hubs operate in Full Duplex Mode

Answer 23

False. Hubs operate in Half Duplex Mode.

Question 24

True or False: Hubs can send and receive data at the same time

Answer 24

False. Hubs can only send or receive. They cannot do both at the same time

Question 25

True or False: Switches operate in Half Duplex Mode only

Answer 25

False. Switches operate in Full and Half Duplex Mode.

Question 26

True or False: Collision detection is required on a switch

Answer 26

False. This is because each port is it’s own collision domain.

Question 27

True or False: Most switches that are connected to each other through a trunk port will have multiple MAC Addresses mapped to that port because that port is the path to other switch that hosts are coming off of

Answer 27

True

Question 28

What ethernet standard is built into switches where if multiple devices transmit data to a port at the same time the switch forces a retransmit of the data?

Answer 28

CSMA / CD (Carrier Sense Multiple Access / Collision Detection)

Question 29

This is a networking device, either hardware or software based, that controls access to the organization’s network

Answer 29

Firewall
