How does IPv6 address the issue of broadcast traffic in networks, which is prevalent in IPv4?
- By eliminating broadcast communication and using multicast and anycast for efficient communication.
- By increasing the broadcast domain size to accommodate more devices.
- By introducing a new broadcast protocol specifically designed for IPv6.
- By limiting the number of devices in a network to reduce broadcast traffic.
IPv6 addresses the issue of broadcast traffic by eliminating broadcast communication and using multicast and anycast for efficient communication.
In a scenario with multiple VLANs, how does inter-VLAN routing occur?
- Through Layer 2 switches
- Through VLAN tunneling
- Using VLAN trunks
- Via a router or Layer 3 switch
Inter-VLAN routing occurs through a router or Layer 3 switch, which routes traffic between different VLANs.
What is the maximum data transmission speed supported by Category 6 (Cat6) Ethernet cables?
- 1 Gbps
- 1 Tbps
- 10 Gbps
- 100 Gbps
Category 6 (Cat6) Ethernet cables support a maximum data transmission speed of 10 Gbps.
What is the main advantage of using LACP (Link Aggregation Control Protocol) over PAgP (Port Aggregation Protocol) in EtherChannel configuration?
- LACP provides standards-based compatibility
- LACP supports dynamic negotiation with non-Cisco devices
- PAgP is more efficient in high-traffic environments
- PAgP is the only option for Layer 3 EtherChannels
The main advantage of LACP is its standards-based compatibility, allowing dynamic negotiation with devices from different vendors.
A network engineer is configuring a network that needs a large number of IP addresses. Which IP version should they consider for an ample supply of addresses?
- IPX
- IPv4
- IPv5
- IPv6
IPv6 is designed to provide an ample supply of IP addresses, making it suitable for networks requiring a large number of addresses.

The integration of Machine Learning in network automation allows for real-time data processing and decision-making based on network state.
A network engineer is configuring a GRE tunnel to connect two remote sites over the internet. What additional security mechanism should they consider implementing to protect the data?
- IPsec
- SSL
- TLS
- SSH
When configuring a GRE tunnel, additional security can be provided by implementing IPsec to encrypt the data transmitted between the remote sites over the internet.
