Here are the answers to Monday's Cisco CCNA and CCNP practice questions!
CCNA Certification:
What mode of switching gives the most protection against damaged frames?
A. store-and-forward
B. expedited
C. fragment-free
D. cut-through
E. Cisco Accelerated Switching (CAS)
Answer: A. Store-and-forward switching temporarily stores a packet and checks it against the Cyclical Redundancy Check (CRC) field. The entire frame is stored before transmission begins.
The amount of latency with store-and-forward switching is dependent upon the length of the frame; the larger the frame, the greater the latency.
CCNP Certification / BSCI Exam:
The administrative distance of ISIS is ____________.
Answer: 115.
CCNP Certification / BCMSN Exam:
R3's port fast 0/10 is configured with Root Guard. An inferior BPDU is received on that port. What will happen?
A. Nothing.
B. The port will go into root-inconsistent state.
C. The port will go into err-disabled state.
D. The port will go into blocking state.
Answer: A. Root Guard takes no action when an inferior BPDU is received. When a superior BPDU is received, though, the port will go into root-inconsistent state.
CCNP Certification / ISCW Exam:
When you're running an IPSec VPN, what happens to "uninteresting traffic"?
A. It is not sent across the VPN.
B. It is not sent across the VPN and a syslog message is generated.
C. The traffic is transmitted, but it is not protected by IPSec.
D. The traffic is transmitted and protected by IPSec.
Answer: C. The traffic will pass over the VPN but will not be protected by IPSec.
CCNP Certification / ONT Exam:
NBAR can analyze payload contents up to a certain number of bytes. What is that number?
Answer: 400 bytes, but some recent Cisco IOS releases offer a larger capability.
