ACTUAL ANSWERS NEW!!!
An attacker created a rogue access point (AP) with the same Service Set Identifier (SSID) as a
legitimate one, and then used a Denial of Service (DoS) technique to overcome the legitimate
AP. Users were forced to disconnect from the network and reassociate with the attacker's AP.
What is the goal of the attacker when setting up this kind of evil twin attack? (Select all that
apply.) - CORRECT ANSWER>>>>To steal user network credentials / To snoop on connections
with web servers
A user is connected to a remote desktop using the protocol WebSockets. What technology
solution is the user using? - CORRECT ANSWER>>>>Clientless VPN

2001:4860:4860:8888? - CORRECT ANSWER>>>>AAAA
A user reported a performance issue on the network the department's web server is
communicating on. After questioning a few other users, and notating some recent changes on the
server and its symptoms, what other actions will a network admin most likely take to better
identify the problem? - CORRECT ANSWER>>>>Try and duplicate the problem.
Which technology offers a mode for simultaneous two-way communication? - CORRECT
ANSWER>>>>Duplex
A user is having trouble connecting to the company's WiFi network. They have verified that the
password is correct and the network is indeed available. What could be a potential issue with the
device not connecting? - CORRECT ANSWER>>>>Encryption protocol mismatch
A company is considering using a co-location connection with a cloud service provider to
support some virtual services in its data center. This will provide the company a private and
hybrid cloud model to easily move services from the local infrastructure to the cloud during peak
season by using infrastructure as code tools. Which of the following network components are
most likely required for hybrid solution? (Select all that apply.) - CORRECT
ANSWER>>>>VLAN / Private link
A network technician suspects a short in the network cable and wants to test it. Identify which of
the following tools will provide this capability. - CORRECT ANSWER>>>>Multimeter
A network engineer is designing a network in various offices to create multiple broadcast
domains. Each has its own Virtual Local Area Network (VLAN). When configuring these
multiple broadcast domains on the switch, the switch will be operating at what layer of the OSI
model? - CORRECT ANSWER>>>>Layer 3
, A network administrator is measuring Key Performance Indicators (KPI) for an industrial
network. Which of the following are examples of a KPI? (Select all that apply.) - CORRECT
ANSWER>>>>Mean Time Between Failures (MTBF) / Mean Time to Repair (MTTR)
Upon reviewing the inclement weather plan for Company A, the network engineer wants to
purchase standby power supplies that can run on diesel or propane. What could the engineer
purchase to fulfill this requirement? - CORRECT ANSWER>>>>Generator
What are two parts of the first step of the CompTIA Network+ troubleshooting methodology?
(Select all that apply.) - CORRECT ANSWER>>>>Identify symptoms / Gather information

corrosion on one of the circuit boards and notices some water on the bottom of the casing. What
hazards could have affected this server? (Select all that apply.) - CORRECT
ANSWER>>>>Humidity / Flooding
A communications company uses TIA/EIA IS-95 handsets that require each subscriber to use a
code to key the modulation of their signal. The receiver uses this "key" to extract the subscriber's
traffic from the radio signal. What type of handsets is the company using? - CORRECT
ANSWER>>>>CDMA
A network administrator is unable to access files on a remote system. A network firewall seems
to be blocking traffic from passing through. Which of the following will the administrator most
likely need to reconfigure for inbound and outbound traffic? (Select all that apply.) - CORRECT
ANSWER>>>>TCP port 20 / TFTP traffic
A network engineer wants all wireless clients to connect to use the same broadcast domain
without connecting to another wireless network. What is this called? - CORRECT
ANSWER>>>>Wireless client isolation
A network administrator would like to setup a group of servers to retrieve the same content from
a single host on the internal network. Which of the following will allow this type of data flow?
(Select all that apply.) - CORRECT ANSWER>>>>IGMP must be used to configure group
membership. / A multicast IP address is assigned to the servers.
A helpdesk technician is helping a user attempt to connect to the network but they are receiving a
169 address. What is this? - CORRECT ANSWER>>>>Link-local
A network administrator is researching network virtualization and is trying to find a standard
architecture for appliances to be developed against. Which of these should the administrator look
at for a standard? - CORRECT ANSWER>>>>NFV
A network consultant wants to install software to protect the company infrastructure from
outside influence. What can the consultant use to block unwanted/unauthorized access? -
CORRECT ANSWER>>>>Firewalls
