What is the primary advantage of using EIGRP over RIP in a network?
- Low bandwidth usage
- Rapid convergence
- Simple configuration
- Support for VLSM
EIGRP (Enhanced Interior Gateway Routing Protocol) has the advantage of supporting Variable Length Subnet Masking (VLSM) in comparison to RIP.
How does BGP's route aggregation feature benefit network performance and scalability?
- Reducing the number of routing entries
- Increasing the BGP peer connections
- Utilizing MPLS technology
- Implementing OSPF as the IGP
BGP's route aggregation feature benefits network performance and scalability by reducing the number of routing entries in the routing table.
How does SDN address the issue of scalability in large network infrastructures?
- By decoupling the control plane from the data plane, SDN allows centralized control, making it easier to scale and manage large networks.
- By using traditional routing protocols that automatically scale to accommodate network growth.
- By relying on complex distributed algorithms that dynamically adjust network resources.
- By limiting the size of the network to maintain manageable scalability.
SDN addresses scalability by decoupling the control and data planes, enabling centralized control for easier scaling in large networks.

- Troubleshooting
- Ping Test
- Trace Route
- Layered Testing
Layered testing is a common method where the functionality of each network component is verified in order, starting from the physical layer.
_________ mode in Port Security allows dynamically learned MAC addresses to be retained even if the switch is restarted.
- Dynamic
- Secure
- Static
- Sticky
Sticky mode in Port Security allows dynamically learned MAC addresses to be retained even if the switch is restarted.
________ was a popular choice for digital telecommunication networks before being overshadowed by newer technologies.
- ISDN (Integrated Services Digital Network)
- ATM (Asynchronous Transfer Mode)
- Frame Relay
- X.25
ISDN (Integrated Services Digital Network) was a popular choice for digital telecommunication networks before being overshadowed by newer technologies like broadband and fiber optics.
Which type of network link is necessary to transport multiple VLANs across network devices?
- Access Link
- Ethernet Link
- Point-to-Point Link
- Trunk Link
A trunk link is necessary to transport multiple VLANs across network devices, allowing for the passage of tagged VLAN traffic.
IPSec's ________ mode encrypts the entire IP packet for secure data transmission.
- Transport
- Tunnel
- Network
- Security
IPSec's Tunnel mode encrypts the entire IP packet for secure data transmission.
During an audit, it's found that an unauthorized DHCP server is distributing IP addresses, leading to network issues. Which Layer 2 feature can prevent this scenario?
- DHCP Snooping
- MAC Spoofing
- Port Security
- VLANs
DHCP Snooping is a Layer 2 feature that can prevent unauthorized DHCP servers from distributing IP addresses, ensuring network integrity.
What is the role of YAML in network automation scripts?
- It defines network protocols for communication.
- It is used for configuring network devices directly.
- It is a scripting language for automation.
- It provides a human-readable data format for configuration files.
YAML in network automation scripts plays the role of providing a human-readable data format for configuration files, making it easier for users to understand and modify configurations.
