What purpose does the following command serve? What protocol is being configured?

R1(config-if)#standby 5 track s0/0 25

CCNP / ONT Exam:

What factors are generally used to determine whether Predictor or Stacker should be used for L2 payload compression?

Here are the answers!

CCNA:? Answer: The password required here is the VTY line password.

CCNA Security / ISCW:? Answer: This is one of three preconfigured Signature Definition Files.

Cisco's website recommends running the Intruder Prevention System (IPS) with the preconfigured files - attack-drop.sdf, 128MB.sdf, and 256MB.sdf. The "128MB" and "256MB" refer to the amount of memory necessary to use these particular files.

BSCI:? Answer: An OSPF area should contain no more than 50 routers.

BCMSN:? Answer: This line configures HSRP Interface Tracking. Serial 0/0 is the tracked interface, and the "25" at the end of this command changes the decrement from its default of 10.

ONT:? Answer: Cisco's website recommends that you choose Predictor if the congestion is due to an overloaded router, while Stacker is a good selection if limited bandwidth is the issue.

AdditionallyBusiness Management Articles, Cisco's recommendation is that you disable compression if the CPU load goes over the 40% mark.
