Hi Group!
The answers to Tuesday's questions are below - and look for a new set of Cisco training questions later today!
You'll also see the latest video in my Cisco Fifty series - 50 free training videos in 50 days!
There's something for everyone in this latest series... and now, on to the questions!
CCNA / CCENT Certification:
Short answer: Convert the binary string 11001001 00011111 10101010 01010101 into a dotted decimal IP address.
Answer: 201.31.170.85.
Short answer: What's so "deadly" about a "ping of death"? What network issues can it cause?
Answer: The ping of death is a ping packet of much larger size than a network device can process, and a POD can cause the intended target to crash.
(My CCNA Voice Study Package will be released in June!)
Briefly describe the unique process known as "router on a stick". Be sure to describe the "stick" part!
Answer: One method of allowing inter-VLAN communication on a single switch, the "stick" is a trunk from a switch port to a Fast Ethernet (or faster) port on a router. Inter-VLAN traffic will travel "up" the trunk to the router and will be routed back "down" the same trunk, although on a different VLAN and different router subinterface.
CCNA Wireless:
What role does LWAPP play on a Cisco wireless network?
Answer: The Lightweight Access Point Protocol (LWAPP) allows the simultaneous control and configuration of multiple Wireless Access Points (WAPs or APs).
Here are today's CCNP questions!
BCMSN Exam:
What command would enable Root Guard on port fast 0/3?
Answer: The syntax is a little odd, so let's take a look at IOS Help:
SW1(config)#int fast 0/3
SW1(config-if)#spanning ?
bpdufilter Don't send or receive BPDUs on this interface
bpduguard Don't accept BPDUs on this interface
cost Change an interface's spanning tree port path cost
guard Change an interface's spanning tree guard mode
link-type Specify a link type for spanning tree protocol use
port-priority Change an interface's spanning tree port priority
portfast Enable an interface to move directly to forwarding on link up
stack-port Enable stack port
vlan VLAN Switch Spanning Tree
SW1(config-if)#spanning guard ?
loop Set guard mode to loop guard on interface
none Set guard mode to none
root Set guard mode to root guard on interface
SW1(config-if)#spanning guard root ?
SW1(config-if)#spanning guard root
ISCW Exam:
Short answer: What's so "resilient" about the Cisco IOS Resilient Configuration, and how can this feature help with network security?
Answer: The Cisco IOS Resilient Configuration is a relatively new feature - it was introduced in 12.3(8)T.
A Cisco router running this feature will both secure and maintain a copy of the starting configuration and the IOS image. Cisco's website states that these copies (the primary bootset) can't be erased by a user.
A new question set coming up later today, along with a new Cisco training video!
