Here are the answers to Tuesday's bonus set of Cisco and CompTIA certification exam questions. All of these questions were short answer.
CCNA:
Convert the following binary string to a dotted decimal address:
00111111 10101111 00101010 01010101
Answer: 63.175.42.85
Network+:
What IEEE standard defines Ethernet?
Answer: Ethernet is defined by IEEE 802.3.
Security+:
Briefly describe SSL. Include any pertinent port numbers.
Answer: SSL is Secure Sockets Layer, an encryption method that involves both a secret and shared key. It's commonly used on sites that require a customer to enter a credit card number. HTTP over SSL runs on port 443.
CCNP / BSCI:
You want one of your IGRP routers to advertise a default route throughout the network. Which command is the most efficient way of doing so?
Answer: With IGRP, there's just one way to propagate a default route, and that's with the ip default-network command. IGRP doesn't accept a route to 0.0.0.0, so the static default route is out. The default-information originate commands are OSPF commands, and ip default-gateway should be used only when IP routing is off.
CCNP / BCMSN:
Briefly describe the purpose of VMPS.
Answer: The VLAN Membership Policy Server allows creation of dynamic VLANs.
CCNP / BCRAN:
In the command aaa authentication login default group radius group tacacs none, what happens if the user fails RADIUS authentication?
Answer: If authentication fails, the process ends with the user being denied access. The second option is looked at only if the first option times out or returns an error.
CCNP / CIT:
By default, why does a DHCP broadcast cross a router?
Answer: Because it's there.
Okay, that's not the answer. The answer is - it doesn't! That's why we need DHCP Relay Agents on occasion.
See you later today with more answers from this past week's questions, and more Cisco and CompTIA certification exam practice questions!
To your success,
