NETWORK+ PRACTICE EXAM 2
1. A network engineer is testing an application over the IPv6 protocol. De-
termine how the server can cast packets to an entire local subnet.
*Answer√√ Multicast to associated private topology
2. A network consultant is asked to install environmental sensors on the or-
ganization's server to monitor conditions in the server rack. Which of the
following factors need monitoring? (Select all that apply.)
*Answer√√ Temperature, Humidity, Electrical
3. A manufacturing company utilizes multiple access points (APs) spread across
its factory. The APs all share an SSID to allow client roaming. Since there are areas
where it is difficult to run cabling, a wireless distribution system is used, where
the main router is connected to the Internet and the rest are set in repeater
mode. What is true about the channels used by the APs?
*Answer√√ All APs must use the same channel
4. A network cable installer is installing copper cabling in an office for a new
,network. The installer needs to close a gap of about 150 ft. ending in an RJ-45
termination. What is the lowest possible category of cable needed to maintain 10
Gigabit Ethernet speeds?
*Answer√√ Cat 6
5. What advantage does Collision Detection (CD) bring to the carrier-sense
multiple access (CSMA) media access control method?
*Answer√√ Instant termination upon collision
6. The network security office is tasked with updating authentication require-
ments for computer access as it currently uses a single sign-on and password.
The office determines that it will begin using the sign-on criteria but add an
additional requirement of a code being sent to the employee's personal cell
phone to grant authorization to complete access requirements for login. What is
the name of this authentication?
*Answer√√ Multi-factor
7. A network specialist is tasked with integrating a VoIP solution in an office
,that uses a legacy analog phone system. The office intends to discontinue its
traditional analog telephone service and eliminate all outdated voice ca-bling.
However, there is also a requirement to continue using existing analog handsets
and fax machines alongside new VoIP endpoints. Which of the following
methods should be implemented to support VoIP services and ensure
compatibility with both legacy and new devices without relying on
, PSTN connections? (Select all that apply)*Answer√√ 1. Install a VoIP PBX for VoIP endpoints and
integrate a Foreign Exchange Subscriber (FXS) gateway to connect legacy analog devices to the new PBX. 2. Connect new
devices to the VoIP PBX and connect that to the legacy telephone network directly through an analog Foreign Exchange Oflce
voice gateway.
8. A network engineer has configured a network with a tiered mesh topology
with multiple redundant links, causing an entire switch segment to become
unusable until being reset. What layer 2 protocol packages data into bridge
protocol data unit (BPDU) multicast frames and routes based on a ranked
hierarchy of switches in order to prevent loops?
*Answer√√ Spanning Tree Protocol (STP)
9. While conducting an analysis, a network technician is attempting to deter-
mine the amount of information that can be transmitted in bits per second
(bps). What is the technician attempting to measure?
*Answer√√ Bandwidth
10. A network technician is troubleshooting a network issue. The technician has
