CIW Network Technology Associate 5 — Questions and Answers
Question 1: A network admin uses the command 'show ip route' on a router and sees the prefix 'O' before a route entry. What does 'O' indicate?
- The route was learned via OSPF (Correct answer)
- The route was learned via EIGRP
- The route is a directly connected network
- The route was manually configured as a static route
Correct answer: The route was learned via OSPF
The 'O' code in the routing table indicates the route was learned via OSPF (Open Shortest Path First), a link-state routing protocol.
Question 2: What type of attack involves an attacker intercepting and potentially altering communications between two parties without their knowledge?
- Denial of Service (DoS)
- Man-in-the-Middle (MitM) (Correct answer)
- SQL Injection
- Phishing
Correct answer: Man-in-the-Middle (MitM)
A Man-in-the-Middle attack occurs when an attacker secretly intercepts and relays communications between two parties who believe they are communicating directly.
Question 3: Which protocol allows network administrators to collect and organize information about managed devices on IP networks?
- FTP
- SNMP (Correct answer)
- SMTP
- Telnet
Correct answer: SNMP
SNMP (Simple Network Management Protocol) is used to monitor and manage network devices by collecting data through a manager/agent model.
Question 4: What is the key difference between a full-duplex and half-duplex Ethernet connection?
- Full-duplex uses fiber while half-duplex uses copper
- Full-duplex allows simultaneous sending and receiving; half-duplex allows only one direction at a time (Correct answer)
- Full-duplex operates at 10 Mbps; half-duplex operates at 100 Mbps
- Full-duplex requires a hub; half-duplex requires a switch
Correct answer: Full-duplex allows simultaneous sending and receiving; half-duplex allows only one direction at a time
Full-duplex allows simultaneous bidirectional data transmission, while half-duplex restricts communication to one direction at a time, requiring collision detection (CSMA/CD).
Question 5: Which address is used by ARP (Address Resolution Protocol) to discover the MAC address of a device on the local network?
- The device's DNS hostname
- A broadcast address (FF:FF:FF:FF:FF:FF) (Correct answer)
- The router's default gateway IP address
- A multicast address reserved for ARP
Correct answer: A broadcast address (FF:FF:FF:FF:FF:FF)
ARP sends a broadcast frame to FF:FF:FF:FF:FF:FF asking all devices on the LAN to identify which one owns a given IP address.
Question 6: In the context of network topologies, which topology provides the highest level of redundancy with direct connections between every node?
- Star topology
- Bus topology
- Ring topology
- Full mesh topology (Correct answer)
Correct answer: Full mesh topology
A full mesh topology connects every node directly to every other node, providing maximum redundancy at the cost of cable count and complexity.
Question 7: Which port number is used by HTTPS (HTTP Secure) by default?
- 80
- 21
- 443 (Correct answer)
- 8080
Correct answer: 443
HTTPS uses port 443 by default, encrypting HTTP traffic using TLS (Transport Layer Security).
