Hey, I owe you some answers - the answers to last Thursday's Cisco certification exam training questions, that is! :) Here they are!

CCNA And CCENT Certification:

What command should you issue on a Cisco 2950 switch to erase all information regarding VLANs?

Answer: delete vlan.dat.

CCNP Certification / BSCI Exam:

What interface-level command will double a router's default OSPF priority on that particular interface?

Answer: ip ospf priority 2, since the default is one.

CCNP Certification / BCMSN Exam:

If you want to specify the protocol that will be used to create an Etherchannel, what interface-level command will you need to use?

Answer: channel-protocol, as shown below.

SW1(config-if)#channel-protocol ?
lacp Prepare interface for LACP protocol
pagp Prepare interface for PAgP protocol

CCNP Certification / ISCW Exam & CCNA Security:

Name three major differences between hard and soft SAN zones.

Hard zoning:

Prevents any communication across the switched fabric

Is hardware-based

Is considered more secure than soft zoning

Soft zoning:

A server can see only allowed devices, *but* can still contact "hidden" devices by their address.

Is software-based

Not particularly secure (putting it nicely)

I'll have new questions for you later today!

To your success,
