Let’s test your knowledge of Telnet, SDF files, and other important Cisco certification exam topics. Answers are at the bottom of the page. No peeking!
CCNA Certification And CCENT Certification:

CCNA Security Certification / CCNP ISCW Exam:
What is the purpose of the 256MB.sdf file? What does the "256" refer to?
CCNP Certification / BSCI Exam:
According to Cisco best practices, an OSPF area should contain no more than how many routers?
CCNP Certification / BCMSN Exam:
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.
Additionally, Cisco's recommendation is that you disable compression if the CPU load goes over the 40% mark.
