Here are the answers to the Cisco CCENT, CCNA, and CCNP practice exam questions posted on Saturday, September 13!



CCNA Certification And CCENT Certification:

In a hub-and-spoke OSPF NBMA network, which router should serve as the Designated Router? What is the most common method of making that particular router the OSPF DR?

Answer; The hub must be the DR, and the most common way of doing so is setting the OSPF interface priority of the spoke routers to zero (the default priority is 1).



CCNA Security Certification / CCNP ISCW Exam:

Which of the following are considered reconnaissance attacks, and which are access attacks?

A. ping sweep

B. port scan

C. password attack

D. trust exploitation

E. DSL query

Answer: Password attacks and trust exploitations are considered access attacks. The other three attacks are recon attacks - attacks that are not primarily created to cause damage, but to gather information for future, more destructive attacks.

A. PIM Sparse

B. PIM Dense

C. PIM Sparse-Dense

D. PIM Broadcast

Answer: B. That's a great scenario in which to use PIM Dense mode.
