CARP -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 -ANSWER What type of network could use the type of connector shown
here?
Its tcp/ip stack is not installed properly -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 -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 -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 -ANSWER Which of the following ports would be used during a domain name
lookup?
NIC teaming -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 -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 -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 -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 -
ANSWER When using NAT, how does an IP gateway ensure that outgoing traffic can
traverse public networks?
RADIUS -ANSWER Which of these authentication techniques only encrypts the
password when transmitting
sign-in credentials?
Establish a theory of probable cause -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 -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 -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
-ANSWER What would the command route del default gw 192.168.5.1 eth1 accomplish
on your Linux workstation?
TCP port 23 -ANSWER From your laptop, you need to remote into a switch to make
some configuration changes. Which Transport layer protocol and TCP/IP port should
you open in Windows Firewall to make this work using Telnet?
NIPS -ANSWER Recently, your company's WAN experienced a disabling DDoS attack.
Which of the following devices could detect such an attack and prevent it from affecting
your network in the future?
