Technical Support Engineer 3 Interview Questions and Answers

ACL AD value and AS number are related to network security and routing protocols.

• ACL AD value is the Access Control List Administrative Distance value, which is used to determine the priority of a particular ACL entry in case of multiple entries matching a packet.

• AS number is the Autonomous System number, which is used in Border Gateway Protocol (BGP) to identify a group of networks under a single administrative domain.

• ACL AD value and AS number are both important in network ...read more

STP, OSPF, and BGP are routing protocols used in computer networks.

• STP (Spanning Tree Protocol) is used to prevent loops in Ethernet networks.

• OSPF (Open Shortest Path First) is a link-state routing protocol used in IP networks.

• BGP (Border Gateway Protocol) is used to exchange routing information between different autonomous systems.

• STP and OSPF are used in local area networks (LANs), while BGP is used in wide area networks (WANs).

Inter VLAN routing is the process of forwarding network traffic between different VLANs.

• Inter VLAN routing can be achieved through a router or a layer 3 switch.

• It requires the use of a routing protocol such as OSPF or EIGRP.

• VLANs must be configured with unique IP subnets to enable inter VLAN routing.

• ACLs can be used to control traffic flow between VLANs.

• Inter VLAN routing can improve network performance and security by segregating traffic.

• Example: A company may have separate ...read more

There are two types of IP routing: static and dynamic.

• Static routing involves manually configuring the routes in the routing table.

• Dynamic routing uses protocols to automatically update the routing table.

• Examples of dynamic routing protocols include OSPF, BGP, and RIP.

• Static routing is simpler and more secure, but less flexible than dynamic routing.
