Here are the answers to Tuesday's Cisco and CompTIA certification questions!
CCNA:
Express the following hex value in dotted decimal: F7
Answer: F7 equals 247 in decimal; in dotted decimal, that's 11110111.
Network+:
What is the prefix length of the mask used for Class B private addresses?
A. /8
B. /12
C. /16
D. /20
E. /24
F. /32
Answer: B. While the default mask of a Class B address is /16 (255.255.0.0), the mask for the private address range of Class B addresses is /12 (255.240.0.0).
CCNP / BCRAN:
Once a cable modem is powered on, what's the first thing it needs to do?
A. Acquire a SYNC signal
B. Acquire a RF signal
C. Acquire a MAP signal
D. Acquire a QAM LOCK signal
Answer: B. The cable modem must find a Radio Frequency (RF), also called a DOCSIS channel.
CCNP / BCMSN:
A switch is running Uplinkfast. The original root port has gone down and now come back up. Assuming the switch is running all default settings, how long will it be before this port becomes the root again?
A. 100 - 300 milliseconds
B. 1 - 3 seconds
C. 30 - 35 seconds
D. 120 - 150 seconds
E. That port won't become the root again.
Answer: C. The original root will become the root port when it comes back up, but not immediately. The formula is (2 x Forward Delay) + 5 seconds. With default settings, that's 35 seconds.
CCNP / BSCI:
Which of the following statements is NOT one of the activities at the distribution layer of the Cisco Three-Layer Hierarchical Model?
A. traffic filtering
B. policy routing
C. internet access
D. end user / network interaction
E. address aggregation / summarization
Answer: D. End user interaction with the network occurs at the Access layer.
CCNP / CIT:Short answer:
What troubleshooting model are you using if your first step is to examine the routing table?
Answer: If you begin troubleshooting at a middle layer of the OSI model, you're using the divide-and-conquer troubleshooting method.
