To enhance security, GRE tunnels are frequently paired with ______, which provides encryption and authentication.
- IPsec
- OSPF
- VLAN
- SNMP
To enhance security, GRE tunnels are frequently paired with IPsec, which provides encryption and authentication.
What is the primary difference between IPv6 and IPv4 addressing in terms of address length?
- 128 bits
- 256 bits
- 32 bits
- 64 bits
IPv6 addresses are 128 bits long, which is a significant increase from IPv4's 32-bit addresses.
Which topology uses a hybrid approach, combining elements of both star and bus topologies for improved performance?
- Bus
- Hybrid
- Mesh
- Star
A hybrid topology combines elements of both star and bus topologies for improved performance. It offers the advantages of both topologies.
What version of SNMP provides message integrity, authentication, and encryption for secure management of network devices?
- SNMPv1
- SNMPv2c
- SNMPv3
- SNMPv4
SNMPv3 (Simple Network Management Protocol version 3) provides message integrity, authentication, and encryption for secure management of network devices.
In a mixed-vendor environment, which EtherChannel protocol is preferred and why?
- Both are equally compatible
- LACP
- Neither, use static EtherChannel
- PAgP
In a mixed-vendor environment, LACP is preferred as it is a standards-based protocol, ensuring compatibility with devices from different vendors.
In VLSM, smaller subnets can be created by borrowing ________ bits from the host portion of the address.
- Additional
- Fewer
- More
- Unused
In VLSM, smaller subnets can be created by borrowing more bits from the host portion of the address.
How many bits are used in an IPv6 address, making it capable of providing a larger address space than IPv4?
- 128
- 16
- 32
- 64
An IPv6 address uses a total of 128 bits, providing a significantly larger address space than IPv4.
The process by which STP recalculates the best path when the network topology changes is known as _______.
- Dijkstra's Algorithm
- Link State Advertisement
- Routing Information Protocol
- Topology Change Notification
The process by which STP recalculates the best path when the network topology changes is known as Topology Change Notification. STP adapts to changes in the network to maintain a loop-free topology.
The process of dividing an IP network into subnetworks is known as _______.
- Fragmentation
- Routing
- Subnetting
- Switching
The process of dividing an IP network into subnetworks is known as subnetting. Subnetting allows for better organization and management of IP addresses within a network.
EtherChannel uses multiple ______ to increase the link bandwidth between two network devices.
- Frames
- Paths
- Ports
- Protocols
EtherChannel uses multiple ports to increase the link bandwidth between two network devices.
