What happens when a switch receives a frame on a trunk port without a VLAN tag?
- The frame is dropped
- The switch assigns a default VLAN
- The switch forwards the frame to all VLANs
- The switch sends a VLAN membership request
When a switch receives a frame on a trunk port without a VLAN tag, the switch assigns a default VLAN to the frame.
Which protocol uses the DUAL algorithm to ensure loop-free and rapid convergence?
- BGP
- EIGRP
- OSPF
- RIP
EIGRP (Enhanced Interior Gateway Routing Protocol) uses the DUAL (Diffusing Update Algorithm) to ensure loop-free and rapid convergence in routing.
_________ enables dynamic, programmatically efficient network configuration in SDN to improve network performance and monitoring.
- OpenFlow
- REST API
- Python scripting
- NETCONF
OpenFlow enables dynamic, programmatically efficient network configuration in SDN to improve network performance and monitoring.
A non-root bridge port that is selected to forward traffic towards the root bridge is called a _______ port.
- Blocking Port
- Designated Port
- Listening Port
- Root Port
A non-root bridge port that is selected to forward traffic towards the root bridge is called a Root Port. The Root Port offers the shortest path to the root bridge.
In an organization where network redundancy and reliability are crucial, the network administrator is tasked with choosing a topology that ensures continuous network operation even if one connection fails. Which topology is the most suitable?
- Bus
- Mesh
- Ring
- Star
Mesh topology provides maximum redundancy and reliability as every device is connected to every other device, ensuring continuous operation even if one connection fails.
An IT manager is troubleshooting intermittent WAN connectivity issues. What should be the initial step in diagnosing the problem?
- Check for Physical Layer Issues
- Analyze Network Traffic
- Review Router Configurations
- Monitor WAN Bandwidth
Checking for physical layer issues, such as cable connections and hardware problems, is the initial step in diagnosing intermittent WAN connectivity issues.
What is the primary function of the control plane in a Software-Defined Networking (SDN) architecture?
- Data forwarding
- Network management
- Control and decision-making
- Physical device configuration
The control plane in SDN is responsible for control and decision-making, separating it from the data plane for flexibility and programmability.
________ is a network device that strengthens the signal along a network cable and works on the principle of signal regeneration.
- Bridge
- Hub
- Modem
- Repeater
A Repeater is a network device that strengthens the signal along a network cable and works on the principle of signal regeneration.
A network administrator is tasked with designing a subnetting scheme for a university campus. The scheme needs to efficiently accommodate varying sizes of departments and user groups. What approach should they adopt?
- CIDR (Classless Inter-Domain Routing)
- Classful Subnetting
- Supernetting
- Variable Length Subnet Masking (VLSM)
Variable Length Subnet Masking (VLSM) is suitable for accommodating varying sizes of departments and user groups in a subnetting scheme for a university campus.
What is a key benefit of implementing TACACS+ in AAA?
- Centralized Authentication
- Encryption of Data
- Load Balancing
- Port Security
TACACS+ provides centralized authentication, which is a key benefit in AAA (Authentication, Authorization, and Accounting) systems.
