Explaining Network Topologies
This network topology connects each device to a central hub, allowing communication through the hub.
What is a star topology?
This type of copper cabling, known for its high interference protection and reduced crosstalk, is used in sensitive data transmission areas.
What is Shielded Twisted Pair (STP)?
This device separates collision domains by making every port its own collision domain and allows full-duplex communication through micro-segmentation.
What is a switch?
This is the type of address in IPv4 that is used to send data only to a single destination.
What is a unicast address?
This method of routing requires manual configuration and is best suited for small, stable networks.
What is static routing?
This type of network is confined to a single geographical location, such as a home or office.
What is a Local Area Network (LAN)?
These two types of fiber cables are differentiated by their core diameter, with one being used for long distances and the other for shorter distances within data centers.
What are Single Mode and Multimode Fiber?
This 48-bit alphanumeric identifier is unique to each network device and is used at the Data Link layer.
What is a MAC address?
This class of IP addresses uses a default subnet mask of 255.255.255.0.
What is Class C?
This dynamic routing protocol is Cisco proprietary and uses multiple metrics like bandwidth and delay to determine the best path.
What is EIGRP?
This OSI model layer is responsible for the physical transmission of data using cables or wireless media.
What is the Physical Layer?
This installation component, used to centralize and manage cable connections in server rooms, supports both T568A and T568B wiring standards.
What is a Patch Panel?
This protocol, used at Layer 2, prevents network loops and provides fault tolerance by blocking redundant paths in a network.
What is Spanning Tree Protocol (STP)?
This term refers to the IPv6 address type that allows communication with the nearest device in a group.
What is an anycast address?
This command displays the routing table on a router, providing critical information about packet forwarding.
What is the show route command?
In this topology, every node is connected to every other node, providing high redundancy and fault tolerance.
What is a mesh topology?
This fiber optic cable connector, commonly used in telecommunications, has a square-shaped push-pull design for quick deployment.
What is the Subscriber Connector (SC)?
When multiple physical connections are combined into a single logical link for redundancy, this technique is being used.
What is link aggregation or NIC teaming?
This command can be used to view a device's current IP configuration, including the subnet mask and default gateway.
What is ipconfig?
In this architecture, multiple layers of switches are used to improve network performance, with core, distribution, and access layers.
What is tiered switching architecture?
This troubleshooting step involves gathering system documentation, questioning users, and inspecting logs to diagnose a network issue.
What is identifying the problem?
This environmental factor is essential for avoiding condensation, preventing corrosion, and reducing the risk of static buildup in server rooms.
What is Humidity Control?
A network experiencing excessive broadcast traffic and connectivity issues is likely suffering from this problem, often caused by improper switch configurations.
What is a broadcast storm or a network loop?
This transition method encapsulates IPv6 packets within IPv4 packets to traverse IPv4 networks.
What is tunneling?
This technology divides a physical network into multiple isolated segments, often based on function or department, without requiring additional hardware.
What is a VLAN?
