CIW Network Technology Associate 3 — Questions and Answers
Question 1: A technician sets up a wireless access point using WPA3. What primary advantage does WPA3 provide over WPA2?
- Faster data throughput on 2.4 GHz
- Stronger encryption and protection against offline dictionary attacks via SAE (Correct answer)
- Backward compatibility with WEP devices
- Automatic channel selection across 6 GHz
Correct answer: Stronger encryption and protection against offline dictionary attacks via SAE
WPA3 replaces the WPA2 Pre-Shared Key handshake with Simultaneous Authentication of Equals (SAE), which resists offline brute-force and dictionary attacks.
Question 2: Which cable type uses light pulses transmitted through glass or plastic strands and is immune to electromagnetic interference?
- Cat 6 UTP
- Coaxial cable
- Fiber optic cable (Correct answer)
- Shielded twisted pair (STP)
Correct answer: Fiber optic cable
Fiber optic cable transmits data as light, making it immune to EMI and suitable for long-distance, high-bandwidth connections.
Question 3: What is the default administrative distance for a static route in Cisco IOS?
- 0
- 1 (Correct answer)
- 90
- 110
Correct answer: 1
Static routes have a default administrative distance of 1 in Cisco IOS, making them preferred over most dynamic routing protocols.
Question 4: Which DHCP message does a client broadcast to discover available DHCP servers on the local network?
- DHCPOFFER
- DHCPREQUEST
- DHCPDISCOVER (Correct answer)
- DHCPACK
Correct answer: DHCPDISCOVER
A DHCPDISCOVER message is the first broadcast a client sends to locate any available DHCP servers on the subnet.
Question 5: In the context of network security, what is a DMZ (Demilitarized Zone)?
- A zone where all traffic is encrypted with IPsec
- A network segment that sits between the public Internet and the internal private network, hosting public-facing services (Correct answer)
- A reserved IP address range used only for management traffic
- A VLAN that blocks all inbound traffic by default
Correct answer: A network segment that sits between the public Internet and the internal private network, hosting public-facing services
A DMZ is a perimeter network segment that exposes external-facing services (web, mail, DNS) while shielding the internal LAN from direct Internet access.
Question 6: Which routing protocol uses bandwidth and delay as its composite metric by default?
- RIP
- OSPF
- EIGRP (Correct answer)
- BGP
Correct answer: EIGRP
EIGRP uses a composite metric based on bandwidth and delay (and optionally reliability, load, and MTU) to select the best path.
Question 7: What happens at the Data Link layer when a switch receives a frame destined for a MAC address not in its CAM table?
- The frame is dropped immediately
- The frame is flooded out all ports except the one it was received on (Correct answer)
- The switch broadcasts an ARP request
- The frame is forwarded to the default gateway
Correct answer: The frame is flooded out all ports except the one it was received on
When a switch cannot find a destination MAC address in its Content Addressable Memory (CAM) table, it floods the frame out all ports except the source port.
