Here are the answers to Thursday's CCNA, CCNP, Network+, and Security+ exam questions!
CCNA:
A frame comes into a switch on port fast0/1. The switch does a lookup on the destination MAC, and sees that the destination is also found off fast 0/1. What action describes how the frame will be handled?
A. forwarded
B. filtered
C. flooded
D. multicast
Answer: B. When the source and destination MAC addresses are found off the same port, the frame will be filtered; that is, the frame will not be forwarded in any fashion by the switch.
Network+ :
Short Answer: Physical addresses are used at what layer of the OSI model? Give both the "official" name and the layer number commonly used to refer to this layer.
Answer: Physical addresses are another name for MAC addresses, referring to the fact that the address is physically present on the NIC. MAC addresses operate at the Data Link layer, or "Layer 2".
Security+ :
What port number does SSL use?
A. 80
B. 8080
C. 443
D. 143
E. 83
Answer: C. SSL, the Secure Sockets Layer, runs at port 443.
CCNP / BCSI:
What protocol multicasts updates to 224.0.0.9?
A. RIPv1
B. RIPv2
C. OSPF
D. EIGRP
E. IGRP
F. BGP
Answer: B. RIPv2 multicasts routing updates to 224.0.0.9.
CCNP / BCMSN:
How can you change the speed and duplex of multiple ports with one command?
A. You can't.
