NETWORKING FINAL EXAM
CARP - correct answer ✔✔To ensure that your private network is always protected, you decide to install
three redundant firewalls. Which of the following would allow you to assign the same IP address to all
three?
1000Base-LX - correct answer ✔✔What type of network could use the type of connector shown here?
Its tcp/ ip stack is not installed properly - correct answer ✔✔While troubleshooting a workstation
connectivity problem, you enter the following command: ping 127.0.0.1. The response indicates the test
failed. What can you determine about that workstation?
protocol analyzer - correct answer ✔✔You have been asked to help improve network performance on a
store's small office network. The network relies on two switches, two access points, and a router to
connect its 18 employees to the Internet and other store locations. You decide to determine what type
of traffic the network currently handles. In particular, you're interested in the volume of unnecessary
broadcast traffic that might be bogging down shared segments. Which of the following tools will help
you identify the percentage of traffic made up of broadcasts?
EAPoL - correct answer ✔✔Which of the following standards describes a security technique, often used
on wireless networks, in which a port is prevented from receiving traffic until the transmitter's
credentials are verified by an authentication server?
53 - correct answer ✔✔Which of the following ports would be used during a domain name lookup?
NIC teaming - correct answer ✔✔You are configuring a connection between two backbone switches, and
you want to make sure the connection doesn't fail or become overwhelmed by heavy traffic. Which of
the following techniques would help you achieve both aims?
fingerprint scanner - correct answer ✔✔As a network admin, you have decided to install additional
physical security to the main office's data room. Due to the sensitivity of the data held in this room, you
decide it's critical to ensure two-factor authentication before granting anyone access to the room. You
already have a lock on the door. Which of the following physical security measures would provide 2FA?
, bridged - correct answer ✔✔You have installed and configured two virtual web servers and a virtual mail
server on a physical server. What networking mode will you assign to each server's vNIC to ensure that
the virtual machines' clients on the Internet can access the virtual machines?
onboarding - correct answer ✔✔At the beginning of the school year, students at your school must
configure their computers and other devices to obtain trusted access to the student portion of the
school's network. What is this process called?
It replaces each outgoing packet's source address field with a public IP address - correct answer
✔✔When using NAT, how does an IP gateway ensure that outgoing traffic can traverse public networks?
RADIUS - correct answer ✔✔Which of these authentication techniques only encrypts the password
when transmitting
sign-in credentials?
Establish a theory of probable cause - correct answer ✔✔You are a networking technician in a radiology
clinic, where physicians use the network to transmit and store patients' diagnostic results. Shortly after a
new wing, which contains X-ray and MRI (magnetic resonance imaging) machines, is added to the
building, computers in that area begin having intermittent problems saving data to the file server. After
you have gathered information, identified the symptoms, questioned users, and determined what has
changed, what is your next step in troubleshooting this problem?
stateless firewall / packet-filtering firewall - correct answer ✔✔The software on a firewall you recently
installed on your network examines each incoming packet. It blocks or allows traffic based on a set of
criteria, including source IP address, source and destination ports, and protocols. What type of system is
this? Choose all that apply.
255.255.255.224 - correct answer ✔✔Suppose you have created six subnets on a network that leases a
group of Class C IPv4 addresses. What subnet mask must you specify in your clients' configurations to
adhere to your subnetting scheme?
Remove the workstation's route to the default gateway whose IP address is 192.168.5.1 - correct answer
✔✔What would the command route del default gw 192.168.5.1 eth1 accomplish on your Linux
workstation?
