Welcome! Here are the answers to yesterday's Cisco and CompTIA certification exam practice questions!
CCNA Certification:
Convert the hex value "Cd" into both a decimal value and binary string.
Decimal: We have 12 units of 16 and 13 units of 1; that's 205.
Binary: 205 = 11001101
A+ Exam / Network+ Certification Combination Question:
Name the layers of the TCP/IP networking model and describe how those layers map to the OSI model.
Answer: Going from top to bottom, the Application layer of the TCP/IP Model maps to the Application, Presentation, and Session layers of the OSI model. The Transport layer in the TCP/IP model maps to the Transport layer in the OSI model. The Internetworking (or Internet) layer of the TCP/IP model maps to the Network layer of the OSI model. Finally, the Network Access Layer of the TCP/IP model maps to the Data Link and Ethernet segments of the OSI model.
CCNP / BSCI Exam:
What exactly is a "floating static route", anyway? Why do we use them?
A floating static route is a backup method that is relatively simple to configure. The static route will be exactly the same as a dynamically discovered route in the routing table, but will have a higher AD than that of the dynamic route. If the dynamic route leaves the table, the floating static route will be put into the table in its place; when the dynamic route returns, the floating static route will be removed.
CCNP / BCMSN Exam:
What exactly is an "etherchannel", anyway? Why do we use them?
An etherchannel is a logical bundling of physically separate trunk links. Bundling them allows us to use all available paths between two switches, since the etherchannel is seen as a single connection by STP. If we don't bundle them, only one of the paths will be available and STP will put the rest of them into blocking mode.
See you later today with more questions and answers, plus some other surprises!
