Incedo Interview Questions, Process, and Tips

The OSI model is a conceptual framework used to describe the communication functions of a network.

• The model has 7 layers, each with a specific function.

• The layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer communicates with the layer above and below it.

• The model helps ensure interoperability between different network devices and software.

• Example: When you visit a web...read more

SSL offloading is a process of removing SSL encryption from incoming traffic and decrypting it before sending it to the backend servers.

• SSL offloading is performed by a load balancer like F5 to reduce the processing load on backend servers.

• It improves server performance and reduces latency by offloading SSL processing to a dedicated hardware or software.

• F5 SSL offloading can be configured to support multiple SSL certif...read more

SNAT stands for Secure Network Address Translation and is a feature in F5 that allows for the translation of IP addresses.

• SNAT is used to translate the source IP address of outgoing traffic to a different IP address.

• This can be useful in scenarios where multiple devices are sharing a single public IP address.

• SNAT can also be used to improve security by hiding the actual IP address of a device from the public internet.

• F...read more

STP, HSRP, and FRRP are network protocols used for redundancy and failover. HSRP and VRRP are similar but HSRP is preferred.

• STP (Spanning Tree Protocol) prevents loops in a network by disabling redundant links

• HSRP (Hot Standby Router Protocol) and VRRP (Virtual Router Redundancy Protocol) provide redundancy by allowing multiple routers to share a virtual IP address

• FRRP (Fast Router Redundancy Protocol) is a Cisco propr...read more

The xlate table in ASA is used to keep track of translations between internal and external IP addresses. It is important for IPsec tunnel troubleshooting.

• The xlate table is used to map internal IP addresses to external IP addresses

• It is important for troubleshooting IPsec tunnels because it allows you to see if traffic is being translated correctly

• You can view the xlate table using the 'show xlate' command in the ASA C...read more
