1. Which well-known service is using port "21"
2. What does a next hop of 0.0.0.0 mean in the show ip bgp command output?
3. Name all the ways for installing a prefix in the BGP routing table
4. You have a new internal VLAN combined with specific hosts from existing internal VLANs that need to be given internet access through a new EIP, what is the best way to achieve that on your firewall?

5. Which transport layer protocol is used for "DNS"
6. What is LACP and what is it used for? Explain
7. What protocols do switches use to prevent the broadcasting of multicast traffic?

CGMPSNMPIGMPSTPICMPOSPF
8. If a router learns about the same network prefix through RIP, IGRP, EIGRP, and OSPF, which route will be preferred? Explain
9. Based on the Network Diagram above, Explain the packet flow between pairs of computers: (i.e.: from client #X to client #Z flow: Switch A, Interface X, Interface Z, Switch B)
10. What is route leaking? Briefly Explain
11. Which of these IP address pairs are within the same subnet, if the subnet mask is 255.255.255.224?

192.37.65.3 and 192.37.65.34192.35.43.15 and 192.35.43.20192.37.65.3 and 192.37.66.3192.2.3.4 and 192.2.3.6192.36.42.30 and 192.36.42.40
12.Using the routing table above, determine the best route to reach the host at address 132.19.237.5. Network Output Interface? Explain
13. You have a bgp network with multi vendor peers (Cisco and Palo Alto) and there are 3 sites (A, B and C). Each site has the following subnets attached per the diagram below.
Site A: (ASN: 1.4464) (CISCO)
10.1.1.1/24
10.1.2.1/24
10.1.3.1/24
Site B: (ASN: 1.9464) (CISCO)
10.2.1.1/24
10.2.2.1/24
10.2.3.1/28
Site C: (ASN: 7.41248) (PAN)
10.3.1.1/24
10.3.2.1/24
10.3.3.1/24

The subnets with 1 as the third octet need to be advertied at all sites.
Site A will advertise 10.1.2.1/24 to both sites B and C.
Site B will advertise 10.2.2.1/24 to site A only and 10.2.3.1/28 to site C only.
Site C will advertise 10.3.2.1/24 to site B only and 10.3.3.1/24 to both sites A and B.

For simplicity, we will assume all secondary longer paths are filtered by the recieving router.
Please explain how to accomplish these routing goals on both the cisco side as well as the palo alto side. (feel free to write sudo configs etc. if you think that will be helpful)
14. Explain what the purpose of a Traffic Distribution profile and an interface profile are in configuring SD-WAN in PAN?
15. Explain the difference between a Redistribution profile, and import/export rule when configuring BGP in PAN.
