What happens to runt frames received by a Cisco Ethernet switch? The frame is sent to the default gateway. Explanation: In an attempt to conserve bandwidth and not forward useless frames, Ethernet devices drop frames that are considered to be runt (less than 64 bytes) or jumbo (greater than 1500 bytes) frames.
Packet Tracer allows users to create simulated network topologies by dragging and dropping routers, switches and various other types of network devices. A physical connection between devices is represented by a 'cable' item. Cisco Systems claims that Packet Tracer is useful for network experimentation.

As a special customer service, and to improve the overall security of the Internet, Cisco may offer customers free of charge software updates to address security problems. Head over to a handy on-line Cisco tool to identify what vulnerabilities are present in the version of IOS you're running.
Cisco IOS on UNIX (IOU) is another option for running Cisco routers in a virtual environment. It is a fully working version of IOS that runs as a user mode UNIX (Solaris) process. IOU was built as a native Solaris image and runs just like any other program.
How to Install a Cisco (IOS) Router On GNS3 VM
- Step 1: Open the gns3 VM then navigate to -> Edit->preferences -> Dynamips -> IOS routers.
- Step 2: Now click on new and select option “Run IOS Router in GNS3 VM” and press NEXT.
For those not in the know, Cisco's Virtual Internet Routing Lab (VIRL) is a network design and simulation environment that includes a graphical user interface, much like GNS3, to build virtual network topologies.
Cisco IOSv appliance. Cisco Virtual IOS allows user to run IOS on a standard computer.
Explanation:The /24 shows that the network address is 172.17. 4.0. The broadcast address for this network would be 172.17. 4.255.
Explanation:A switch, as a Layer 2 device, does not need an IP address to transmit frames to attached devices. However, when a switch is accessed remotely through the network, it must have a Layer 3 address. The IP address must be applied to a virtual interface rather than to a physical interface.
Packet Tracer 7.3 workspace improvements :
- New workspace themes.
- Aligned workspace objects.
- Ability to deploy network devices to a specific rack.
- Accessibility update.
- Ability to name a physical rack.
The next screen displays the license agreement. Select the "I accept the agreement" option and click the Next button. The next screen allows us to customize the installation directory. By default, the packet tracer is installed in the "Program File" folder of the Windows partition.
What type of network traffic requires QoS? Explanation: Video conferencing utilizes real-time audio and video communications. Both of these are time-sensitive and bandwidth-intensive forms of communication that require quality of service to be active on the network.
The software version number remains visible in the About screen of the Packet Tracer software. To access the About screen, start Packet Tracker, click the Help menu at the top of the user interface, and then select About. Q.
Like IPv4, a 'C' next to a route indicates that this is a directly connected network. An 'L' indicates the local route. In an IPv6 network, the local route has a /128 prefix. Local routes are used by the routing table to efficiently process packets with a destination address of the interface of the router.
The main purpose of a router is to connect multiple networks and forward packets destined either for its own networks or other networks. A router is considered a layer-3 device because its primary forwarding decision is based on the information in the layer-3 IP packet, specifically the destination IP address.
To create VLAN interfaces:
- Determine the IP addresses that you want to assign to the VLAN interfaces on the switch.
- Open a web browser.
- In the browser address field, type the IP address of the smart switch.
- Type the password in the Password field.
- Click the Login button.
- Select Routing>IP>IP Configuration.
What are two functions of a router? (Choose two.)
- A router connects multiple IP networks.
- It controls the flow of data via the use of Layer 2 addresses.
- It determines the best path to send packets.
- It provides segmentation at Layer 2.
- It builds a routing table based on ARP requests. Explanation:
Why are two strands of fiber used for a single fiber optic connection? The two strands allow the data to travel for longer distances without degrading. They prevent crosstalk from causing interference on the connection. They increase the speed at which the data can travel.
SSH makes connections over the network, whereas Telnet is for out-of-band access. SSH provides security to remote sessions by encrypting messages and using user authentication. SSH must be configured over an active network connection, whereas Telnet is used to connect to a device from a console connection.
The NIC uses the destination MAC address which means that B is the answer.
Cisco is a US technology company that is best known for its networking products. Headquartered in California, Cisco develops, manufactures and sells networking hardware, telecoms equipment and other IT services and products.
OSPF uses the following criteria to select the router ID:
- Manual configuration of the router ID.
- Highest IP address on a loopback interface.
- Highest IP address on a non-loopback interface.
