#1. To eliminate the need for adjacent routers on broadcast networks to form n(n-1)/2 adjacencies, IS-IS defines a pseudonode or Designated Intermediate System, DIS. All routers on the broadcast medium form an adjacency with the DIS. The Backup DIS is called...?

#2. For communication systems, what describes the over-all health of the system?

#3. You work as a network engineer at Company.com. There is a connection routed between two IGXs on a single trunk. That trunk fails, and the connection re-routes via another IGX, so it is now a two-hop connection. The failed trunk is repaired. Absent a preferred route, what happens?

#8. Exhibit:
You work as a network engineer at Company.com. The diagram shows a collapsed L3 switched building backbone consisting of two L3 switches: W and U. Each L3 switch has a routed interface on every subnet (VLAN) in the building. There are no VLAN trunks in the network. In other words the L3 switches are acting as native routers. There are exactly 4 client-side VLANs (subnets): a, b, c, d. There are exactly 2 server-side VLANs (subnets): x and y. There is one routed link (Subnet e) connecting the L3 switches in the core. How many equal-cost paths to Subnet d does L3 Switch W keep in its routing table?
