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.
Which IPv6 address type is equivalent to IPv4’s private addressing and is used for local communications within a network segment?
- Global Unicast
- Link-Local
- Multicast
- Unique Local
Unique Local IPv6 addresses are equivalent to IPv4's private addressing and are used for local communications within a network segment.
In OSPF, what is the purpose of the designated router (DR) in a broadcast network?
- Elects the router responsible for exchanging routing information with routers in other areas.
- Facilitates efficient communication in broadcast networks by reducing the number of adjacencies.
- Handles the redistribution of external routes into the OSPF routing domain.
- Manages the distribution of routing updates within the OSPF area.
The designated router (DR) in OSPF broadcast networks is responsible for facilitating efficient communication by reducing the number of adjacencies and managing the exchange of routing information.
DHCP _________ is a feature that allows network administrators to reserve specific IP addresses for certain devices.
- Snooping
- Relay
- Reservations
- Superscope
DHCP Reservations is a feature that allows network administrators to reserve specific IP addresses for certain devices.
A _________ NAT policy allows an external user to access a server within a private network by using a pre-defined public IP address.
- Dynamic NAT
- NAT Overload
- PAT (Port Address Translation)
- Static NAT
A Static NAT policy allows an external user to access a server within a private network by using a pre-defined public IP address.
