It's Saturday, October 11, and here are the answers to yesterday's Cisco certification practice exam questions!


CCNA Certification And CCENT Certification:

Identify the true statements.


A. The address table on a Cisco 2950 switch is built by reading source IP addresses.


B. Crossover cables are typically used to connect switches to allow trunks to form.


C. Frame map statements map a remote IP address to a remote DLCI.


D. Reverse ARP dynamically creates IP address-DLCI mappings.

Answers: B. A is false because switches build MAC address tables by reading source MAC addresses, not IP addresses. Frame map statements map local DLCIs to remote IP addresses. It's Inverse ARP that performs that mapping dynamically, not Reverse ARP.



CCNA Security Certification / CCNP ISCW Exam:

A port configured as untrusted by DHCP Snooping receives a DHCP Offer packet. What, if anything, will happen to the port as a result?

Answer: DHCP messages received on trusted interfaces will be allowed to pass through the switch. Not only will DHCP messages received on untrusted interfaces be dropped by the switch, the interface itself will be placed into err-disabled state.



CCNP Certification / BSCI Exam:

A BGP route reflector receives an update from an eBGP peer. Who will this update be "reflected" to?

A. Clients only

B. Nonclients only

C. Clients and nonclients

D. Neither clients nor nonclients

Answer: C. Updates from eBGP peers are sent to all client and nonclient peers.



CCNP Certification / BCMSN Exam:

Is DHCP Snooping enabled by default? If not, how do you enable it?

(Need some help with DHCP Snooping? Check today's other blog posts for a CCNA Security / BCMSN tutorial on this topic!)

Answer: It's not enabled by default. To enable it, run the ip dhcp snooping global configuration command.



CCNP / ONT Exam:


Name the WMM priority levels that map to the following IEEE 802.11e priority levels: 1, 2, 3, 4.

Answer: WMM has four priority levels, 802.11e has eight. Here's how these levels map to each other:

Platinum (Voice) - 802.11e Priority Level of 6 or 7
Gold (Video) - 802.11e Priority Level of 4 or 5
Silver (Best-Effort) - 802.11e Priority Level of 0 or 3
Background (Bronze) - 802.11e Priority Level of 1 or 2
