Section 1: Networking Fundamentals & OSI Model

,1. A technician is troubleshooting a network issue and needs to identify which
layer of the OSI model processes physical (MAC) addresses for frame delivery.
Which layer should the technician identify?

A. Physical Layer
B. Data Link Layer
C. Network Layer
D. Transport Layer

Rationale: The Data Link Layer (Layer 2) processes physical (MAC) addresses for frame
delivery on the local network segment. It handles error detection, flow control, and
media access control .




2. A field tech is configuring a static IP address for a customer's workstation.
Which of the following pieces of information are required? (Select All That Apply)

A. IP address
B. Subnet mask
C. Default gateway
D. Preferred DNS server
E. Alternate DNS server
F. MAC address

Rationale: Configuring a static IP requires the IP address, subnet mask, default gateway,
preferred DNS server, and alternate DNS server. These settings ensure proper network
communication and name resolution .




3. A technician needs to verify the network configuration of a Windows computer.
Which command should be used to view and modify the network configuration?

A. cls
B. netsh
C. systeminfo
D. CTRL + C

,Rationale: The netsh command provides the ability to view and modify network
configuration on a Windows system. cls clears the screen, CTRL + C halts running
commands, and systeminfo yields computer configuration information .




4. A stable Internet connection should exhibit no more than what percentage of
packet loss?

A. 0%
B. 1%
C. 5%
D. 10%

Rationale: A stable Internet connection should exhibit no more than 1% packet loss.
Higher packet loss rates indicate network problems that can affect voice, video, and data
quality .




5. Which of the following protocols is the predominant Application Layer protocol
used by Internet email clients to retrieve and store email messages?

A. SMTP
B. POP3
C. HTTP
D. FTP

Rationale: Post Office Protocol Version 3 (POP3) is the predominant Application Layer
protocol used by Internet email clients to retrieve and store email messages. SMTP is
used for sending email, HTTP is for web browsing, and FTP is for file transfer .




6. Which protocol allows devices in the network to automatically request and be
assigned IP addresses and other network settings?

A. DNS
B. DHCP

, C. ARP
D. SNMP

Rationale: Dynamic Host Configuration Protocol (DHCP) allows devices in the network
to automatically request and be assigned IP addresses and other network settings, such
as workstations on a LAN .




7. A technician knows the logical IP address of a device but needs to learn the
MAC address. Which tool should be used?

A. DHCP
B. ARP
C. DNS
D. SNMP

Rationale: Address Resolution Protocol (ARP) resolves logical IP addresses to physical
MAC addresses. When a device knows an IP address but needs the corresponding MAC
address, it broadcasts an ARP request .




Section 2: Cable Infrastructure & Fiber Optics
8. What uses the 2.4-GHz band and runs at 54 Mbps?

A. 802.11a
B. 802.11b
C. 802.11g
D. 802.11n

Rationale: 802.11g operates in the 2.4 GHz band and has a maximum data rate of 54
Mbps. 802.11a uses 5 GHz, 802.11b is slower, and 802.11n is faster .
