Now that Ernesto has passed, let's catch up on some Cisco and Network+ questions and answers! Here are the answers to this past Friday's questions.
CCNA:
Short answer: Convert the hex value E51 to a decimal value.
Answer: We've got "E" (14) units of 256, 5 units of 16, and 1 unit of 1. That's 3584 + 80 + 1, which equals 3665.
Network+:
Short answer: What Windows-based utility uses ICMP to illustrate the path taken by packets as they are sent to a remote destination?
Answer: This is traceroute. Ping does test connectivity and it does use ICMP, but ping doesn't show you the IP addresses along the path.
CCNP / BSCI:
Short answer: What is the AD of ISIS?
Answer: 115.
CCNP / BCMSN:
Short answer: You're installing a switch at a client site. The switch was at another site previously. With regards to VTP, what's the first thing you should do before installing the switch?
Answer: You better reset that VTP revision number back to zero!
CCNP / BCRAN:
Short answer: Given a CIR of 128 KBPS and a time interval of 1/16th of a second, what is the Bc?
Answer: To determine the Bc, multiple the CIR by the time interval. 1/16 equals roughly .067, and (128000 x .067) equals 8576.
CCNP / CIT:
You want to run a traceroute from a Windows workstation, and to save time you do not want the IP addresses resolved to hostnames. What's the appropriate command to run?
Answer: First, you'll have to use the tracert command; traceroute is a Cisco router command. The -d option prevents the name resolution, which does save a little time. Here are the tracert options:
Options:
-d Do not resolve addresses to hostnames.
-h maximum_hops Maximum number of hops to search for target.
-j host-list Loose source route along host-list.
-w timeout Wait timeout milliseconds for each reply.
See you later today with the answers to the rest of this past weekend's questions, and several sets of Cisco and CompTIA certification exam practice questions!
To your success,
