which TWO statements are necessary conditions?
In order to create a DCC tunnel in the ONS 15454, which TWO statements are necessary
conditions?
1. LDCC tunnels need to be available.
2. The OC-N port where the DCC will be tunneled needs to be enabled.
3. A customer circuit must be provisioned first.
4. Only Ports 1&3 of the OC-3 card can tunnel DCC.
5. SDCC needs to be tunneled separately for transmit and receive directions

Routers E and F are configured for HSRP (Hot Standby Routing Protocol). E has a priority of 100,
while F has a priority of 50. At one point, when E is the active router, it fails, and F takes over as
the active router. A few minutes later, E returns to service. What happens?

A network administrator is using debug commands to check the performance of a network. What
steps can the administrator take to ensure that the “debug” will not require too much CPU, or at
least that she will not have to reboot the router to disable debug? (multiple answer)
