Cisco CCNA 200-125 Exam Questions Dump

1. Which of the following accurately describe how switches and hubs work? (Choose two)
 A switch uses the logical addresses in a packet to send it through the correct port to all VLANs defined on that port.
 A hub uses the hardware address in the frame to forward it to the hosts on the VLAN that corresponds to that address.
 Switches use the hardware address in the frame to send it only to the port where the device is located.
 A hub repeats frames to all ports, regardless of the destination address.

2. Which of the following is the primary role of a firewall?
 To protect network users from accessing dangerous or questionable webpages. The firewall does this using a website blacklist.
 To detect and block messages that contain viruses and worms that could infect the network or workstations.
 To protect networks and workstations by allowing or denying network traffic. The firewall does this using a configured set of rules.
 To protect users from phishing, botnets, and other types of social networking and social media attacks.

3. An enterprise wireless network is different from a home wireless network in which of the following ways? (Choose three)
 On an enterprise wireless network, host devices need to be able to stay connected when they move around the enterprise or campus.
 Wireless network devices in an enterprise wireless network are dedicated devices that perform a single function.
 Wireless network devices in an enterprise wireless network are usually three devices in one that can perform three functions.
 An enterprise wireless network must cover an area as large as a corporate or university campus and have overlapping signal coverage.
 Enterprise wireless networks are easier to manage than home wireless networks.
 An enterprise wireless network must cover an area as large as a corporate or university campus, carefully avoiding any overlap in signal coverage.
 Enterprise wireless network devices also provide a firewall for network security.

4. Which of the following describes the function of a dedicated wireless access point on an enterprise network?
 On an enterprise network, a wireless access point only acts as a bridge between the wireless segment and the wired segment on the same subnet.
 On an enterprise network, a wireless access point only acts as a switch that forwards traffic from the wireless network to the wired network.
 On an enterprise network, a wireless access point only acts as a hub that connects to both the wireless and wired networks.
 On an enterprise network, a wireless access point only acts as a router that connects the wireless network to the wired network.

5. A home wireless access point is usually three devices in one. Which of the following devices are usually found in a home wireless access point? (Choose three)
 Hub
 Wireless LAN Controller
 Wireless Access Point
 Router
 Switch
 Bridge
 Firewall

6. You are deploying a new 10GB Ethernet network using Cat6 cabling. Which of the following are true concerning this media? (Choose two)
 It includes a solid plastic core.
 It is completely immune to EMI.
 It supports 10 Mbps Ethernet connections.
 It is uses twisted 18- or 16-gauge copper wiring.
 It supports multi-mode transmissions

7. You want to implement an Ethernet network using the 1000BaseT standard using the minimum hardware specifications possible. Which of the following should you include in your plan? (Choose two)
 RJ-45 connectors
 Cat5 twisted pair cable
 Multi-mode fiber optic cable
 Cat5e twisted pair cable
 Cat4 twisted pair cable
 LC connectors
 Single-mode fiber optic cable

8. Which of the following statements are true about bridges? (Choose two)
 Bridges give each segment guaranteed bandwidth.
 Bridges maintain a database of routes through a network.
 Bridges connect two networks that use different protocols.
 Bridges connect two network segments with the same network address.
 Bridges broadcast messages from one network segment to another.

9. Which of the following best describe how a switch functions? (Choose two)
 It connects multiple network segments and forwards packets to the appropriate segment.
 It connects multiple segments and broadcasts packets to all of its ports.
 It segments the network and forwards packets based on logical addresses.
 It connects multiple segments of different architectures. It translates packets, and forwards them to the appropriate segment.

 It filters the network traffic based on hardware addresses.
10. Which of the following are general advantages of using routers on your network? (Choose three)
 Routers support multiple routing protocols for better flexibility.
 Routers provide more features, such as flow control, error detection, and congestion control, than switches or bridges.
 Routers provide multiple links between devices to support load balancing.
 Routers are less expensive than bridges or switches.
 Routers require less configuration and management than bridges.
 Routers provide guaranteed bandwidth between two devices.
