Which type of protocol is OSPF and what metric does it use to determine best path?
OSPF (Open Shortest Path First) is a link-state protocol that uses a concept of cost as its metric to determine the best path. The cost is typically based on the bandwidth of the links, with higher bandwidth links being assigned a lower cost.
What is the function of the authentication service?
The primary function of the authentication service is to validate the user identity. This ensures that the person or entity trying to access a system or service is genuinely who they claim to be before any additional actions or permissions are granted.
A customer reports they can no longer access their services and a network administrator has been assigned to investigate. A UFD disabled error status appears on all ports. What caused the issue?
The issue is caused by assigning both a port channel and its individual member ports to an uplink-state group. This configuration can lead to the group becoming inactive, causing the UFD (Uplink Failure Detection) disabled error status on all ports. Ensuring that only either the port channel or its member ports are assigned to the uplink-state group, but not both, would prevent this issue.
What is an advantage of UFD?
Uplink Failure Detection (UFD) automatically shuts down downstream interfaces if all uplinks on a switch fail. This forces servers to transfer traffic to a redundant interface, simplifying path determination and reducing network complexity. Thus, an advantage of UFD is that it reduces network complexity.
Which best describes traffic flow in a campus network environment?
Traffic flow in a campus network environment is best described as North-South. This is because in a campus network, traffic typically flows between end-user devices and the core network, which is a vertical flow pattern commonly referred to as North-South. In contrast, East-West traffic flow is more characteristic of data center environments where data frequently moves laterally between servers within the same data center.
