Question ID: A+-220-1001-MS-13-1-001
Question: New cabling is being installed in an office with a very strict fire code.
Which type of cable should be used?
a. Plenum

b. UTP
c. STP
d. Fiber
Correct Answer: a. Plenum
Exam Domain/Objective: 3.0 Hardware
Exam Subobjective: 3.1 Explain basic cable types, features, and their purposes.
Remediation Chapter: Chapter 13: Networking
Remediation Heading: Twisted Pair Cable in the Corporate Environment
Explanation: Plenum cables are designed with low-smoke, flame-retardant plastics.
If they burn in the event of a fire, they will give off less harmful fumes to humans.
General-purpose UTP/STP/fiber cables are not manufactured with such
considerations in mind.

Question: A technician is setting up a small office network with a cable modem and
a static public IP address provided by the ISP. Which technology should be enabled
to allow the office PCs access to the Internet?
a. DHCP

b. APIPA
c. NAT
d. RIP
Correct Answer: c. NAT
Exam Domain/Objective: 2.0 Networking
Exam Subobjective: 2.6 Explain common network configuration concepts.
Remediation Chapter: Chapter 13: Networking
Remediation Heading: Wireless AP/Router Basic Configuration
Explanation: NAT is used to translate private internal addresses to public external
addresses.


Question ID: A+-220-1001-MS-07-1-003

,Question: A technician wants to configure two drives for maximum performance.
Which setup should he use?
a. RAID 0

b. RAID 1
c. RAID 4
d. RAID 5
Correct Answer: a. RAID 0
Exam Domain/Objective: 3.0 Hardware
Exam Subobjective: 3.4 Given a scenario, select, install and configure storage
devices.
Remediation Chapter: Chapter 7: Storage Devices
Remediation Heading: Fault Tolerance
Explanation: RAID 0 stripes the data across two disks to achieve fast read/write
times. However, RAID 0 is not fault tolerant. A disk failure causes loss of data
access. RAID 1 is disk mirroring, which mirrors your data across two disks for
redundancy. RAID 4 and 5 are both different types of striping with parity, which
requires at least three disks and increases performance and also provides fault
tolerance.




Question ID: A+-220-1001-MS-13-1-004
Question: A technician is installing a network for a small company and is selecting
the network equipment. Which of the following devices will transmit data to all
ports, regardless of the destination?
a. Switch

b. Router
c. Bridge
d. Hub
Correct Answer: d. Hub
Exam Domain/Objective: 2.0 Networking
Exam Subobjective: 2.2 Compare and contrast common networking hardware
devices.
Remediation Chapter: Chapter 13: Networking
Remediation Heading: Ethernet Star Topology

,Explanation: Hubs flood all traffic out all ports except the port on which the traffic
was received. Bridges and switches pass traffic based on the destination MAC
address. Routers pass traffic based on the destination IP address.




Question ID: A+-220-1001-MS-10-1-005
Question: A technician is about to begin replacing a faulty component on a laptop.
What should the technician do first before doing anything else?
a. Put on an antistatic wrist strap

b. Review manufacturer documentation for disassembly procedures
c. Remove the hard disk drive
d. Remove the battery
Correct Answer: b. Review manufacturer documentation for disassembly
procedures
Exam Domain/Objective: 5.0 Hardware and Network Troubleshooting
Exam Subobjective: 5.5 Given a scenario, troubleshoot common mobile device
issues while adhering to the appropriate procedures.
Remediation Chapter: Chapter 10: Mobile Devices
Remediation Heading: Laptops Overview
Explanation: A technician needs to review manufacturer documentation first to
become familiar with the location of the components and which ones need to be
taken out before others can be accessed. While the others steps listed are
important, they should take place after the documentation review.




Question ID: A+-220-1001-MS-07-1-006
Question: A technician has placed an order for a higher-capacity drive for a user
but in the meantime has decided to connect an external drive for storage. Which two
of the following ports would most likely be used to connect to an external hard
drive? (Choose two.)
a. eSATA

b. USB 3.0
c. IDE
d. Molex
Correct Answer: a. eSATA, b. USB 3.0
Exam Domain/Objective: 3.0 Hardware

, Exam Subobjective: 3.2 Identify common connector types.
Remediation Chapter: Chapter 7: Storage Devices
Remediation Heading: Hard Drive Overview
Explanation: eSATA (external SATA) can be used to connect external devices, as
can USB. IDE is an internal type of connector, which is older. Molex connectors are
power connections.




Question ID: A+-220-1001-MS-13-1-007
Question: Which of the following offers the highest level of security for wireless?
a. WEP

b. WPA
c. WPA2
d. WAP
Correct Answer: c. WPA2
Exam Domain/Objective: 2.0 Networking
Exam Subobjective: 2.4 Compare and contrast wireless networking protocols.
Remediation Chapter: Chapter 13: Networking
Remediation Heading: Wireless NIC-Specific Settings
Explanation: WPA2 is the newer, more secure wireless security type available. It
supports encryption of the wireless traffic with AES, which is currently the most
secure encryption algorithm. WPA and WEP are less secure options. A WAP is a
wireless access point, which isn’t a security type.
