10+ SECURED SECURITY SOLUTIONS Interview Questions and Answers

To synchronize routing from OSPF to BGP, redistribute OSPF routes into BGP and adjust metrics accordingly.

• Redistribute OSPF routes into BGP using route redistribution commands

• Adjust metrics to ensure BGP routes are preferred over OSPF routes

• Use route maps to filter and manipulate routes during redistribution

Wait attributes in BGP are used to influence the route selection process by delaying the installation of a route into the IP routing table.

• Wait attributes are used to delay the installation of a route into the IP routing table until the wait timer expires.

• This can be useful in scenarios where a route should not be immediately installed, allowing time for other routes to be considered first.

• Wait attributes can help prevent route flapping by giving time for the network to stabi...read more

OSPF is an interior gateway protocol used within a single autonomous system, while BGP is an exterior gateway protocol used between different autonomous systems.

• OSPF is a link-state routing protocol, while BGP is a path vector routing protocol.

• OSPF uses a shortest path first algorithm to determine the best path, while BGP uses policies and attributes to make routing decisions.

• OSPF is typically used within a single organization's network, while BGP is used to connect different...read more

I have over 10 years of experience in network design, implementation, and troubleshooting.

• Over 10 years of experience in network design

• Skilled in network implementation

• Proficient in network troubleshooting

DR/BDR in OSPF are selected based on their priority and router ID.

• DR/BDR election occurs on multi-access networks like Ethernet

• Priority value is used to determine the DR/BDR, default is 1-255

• Router with highest priority becomes DR, second highest becomes BDR

• If priorities are equal, router with highest router ID wins

• Priority can be manually configured to influence DR/BDR selection

Routing is the process of selecting the best path for network traffic to reach its destination.

• Routing involves determining the optimal path for data packets to travel from the source to the destination.

• Routers use routing tables to make decisions on how to forward packets based on destination IP addresses.

• Routing protocols like OSPF and BGP are used to exchange routing information between routers.

• Dynamic routing allows routers to adapt to network changes by updating their ro...read more

OSPF (Open Shortest Path First) is a routing protocol used to find the best path for data packets in a network.

• OSPF uses a link-state routing algorithm to determine the best path for data packets.

• Routers in an OSPF network exchange link-state advertisements (LSAs) to build a topology map of the network.

• OSPF calculates the shortest path to each network by using Dijkstra's algorithm.

• OSPF supports multiple areas to scale large networks and reduce routing table size.

• OSPF uses cos...read more

Area 0 in OSPF is the backbone area where all other areas connect.

• Area 0 is also known as the backbone area in OSPF.

• All other OSPF areas must connect to Area 0.

• Area 0 is required for OSPF to function properly.

• Area 0 is used to route traffic between different OSPF areas.

Active Directory is a directory service that stores information and manages resources within a network.

• Centralized database for managing network resources

• Allows for user authentication and authorization

• Organizes objects like users, computers, and printers in a hierarchical structure

• Supports group policies for controlling user access and permissions

DHCP stands for Dynamic Host Configuration Protocol, which is a network management protocol used to assign IP addresses to devices on a network.

• Automatically assigns IP addresses to devices on a network

• Helps in managing and organizing network resources efficiently

• Reduces the need for manual configuration of IP addresses

• Ensures that each device on the network has a unique IP address

• Example: When a new device connects to a network, DHCP assigns it an available IP address
