IJRDO Journal Interview Questions and Answers

2 out of 5 pool members are down in F5 bigip load balancer.

• The load balancer is currently using the 3 available pool members to distribute traffic.

• The 2 down pool members need to be fixed or removed from the pool to prevent traffic from being directed to them.

• The load balancer should be monitored to ensure that it is functioning properly and distributing traffic evenly.

• If necessary, additional pool members can be added to the pool to handle increased traffic or to provide red...read more

You can directly connect the server and laptop using a crossover Ethernet cable.

• Use a crossover Ethernet cable to connect the server's network interface card (NIC) to the laptop's NIC.

• Assign static IP addresses to both the server and laptop in the same subnet.

• Configure the network settings on both devices to ensure they are on the same network.

• Test the connection by pinging the server from the laptop to verify connectivity.

HTTP is unsecured protocol while HTTPS is secured protocol using SSL/TLS encryption.

• HTTP stands for Hypertext Transfer Protocol, while HTTPS stands for Hypertext Transfer Protocol Secure.

• HTTP operates on port 80, while HTTPS operates on port 443.

• HTTP does not encrypt data, while HTTPS encrypts data using SSL/TLS.

• HTTPS provides authentication and data integrity along with encryption.

• Websites using HTTPS have a padlock icon in the address bar to indicate a secure connection.

Load sharing in BGP involves distributing traffic across multiple paths to optimize network performance.

• BGP allows for multiple paths to a destination to be advertised and stored in the routing table

• Load sharing can be achieved through equal cost multi-path (ECMP) or unequal cost multi-path (UCMP)

• ECMP distributes traffic evenly across multiple paths with the same cost

• UCMP distributes traffic across paths with different costs based on a configured ratio

• Load sharing can improve...read more

Use the rand() function in C/C++ to generate random numbers.

• Include the header file for the rand() function

• Use srand() to seed the random number generator

• Generate random numbers using rand() function

Routing & switching are networking concepts that involve directing data packets to their destination and connecting devices within a network.

• Routing involves determining the best path for data packets to travel from one network to another.

• Switching involves connecting devices within the same network based on MAC addresses.

• Routers are used for routing data packets between different networks.

• Switches are used for connecting devices within the same network.

• Routing protocols like...read more

SD-WAN technology is a software-defined approach to managing wide area networks, allowing for centralized control and automation.

• SD-WAN uses software to dynamically route traffic across the network based on real-time conditions.

• It can prioritize critical applications and optimize performance by utilizing multiple connection types.

• SD-WAN simplifies network management and reduces costs by replacing expensive MPLS connections with cheaper broadband links.

• It provides visibility i...read more
