Question No : 1 – (Topic 1)
Refer to the exhibit.
ICMP Echo requests from host A are not reaching the intended Cisco 400-101 pdf destination on host B. What is the problem?
A. The ICMP payload is malformed.
B. The ICMP Identifier (BE) is invalid.
C. The negotiation of the connection failed.
D. The packet is dropped at the next hop.
E. The link is congested.
Answer: D
Here we see that the Time to Live (TTL) value of the packet is one, so it will be forwarded to the next hop router, but then dropped because the TTL value will be 0 at the next hop.

Question No : 2 – (Topic 1)
What is the cause of 400-101 exam ignores and overruns on an interface, when the overall traffic rate of the interface is low?
A. a hardware failure of the interface
B. a software bug
C. a bad cable
D. microbursts of traffic
Answer: D

Micro-bursting is a phenomenon where rapid bursts of data packets are sent in quick
succession, leading to 400-101 periods of full line-rate transmission that can overflow packet buffers of the network stack, both in network endpoints and routers and switches inside the network.
Symptoms of micro bursts will manifest in the form of ignores and/ or overruns (also shown as accumulated in “input error” counter within show interface output). This is indicative of receive ring and 400-101 exam corresponding packet buffer being overwhelmed due to data bursts coming in over extremely short period of time (microseconds). You will never see a sustained data traffic within show interface’s “input rate” counter as they are averaging bits per second (bps) over 5 minutes by default (way too long to account for microbursts). You can understand microbursts from a scenario where a 3-lane highway merging into a single lane at rush hour – the capacity burst cannot exceed the total available bandwidth (i.e. single lane), but it can saturate it for a period of time.

Question No : 3 DRAG DROP – (Topic 1)
Drag and drop the extended ping command field on the 400-101 dumps left to its usage on the right.

Question No : 4 – (Topic 1)
Refer to the exhibit.
Which statement about the output is true?
A. The flow is an HTTPS connection to the router, which is initiated by
B. The flow is an HTTP connection to the router, which is initiated by
C. The flow is an HTTPS connection that is initiated by the router and that goes to
D. The flow is an HTTP connection that is initiated by the router and that goes to
Answer: A
We can see that the 400-101 connection is initiated by the Source IP address shown as We also see that the destination protocol (DstP) shows 01BB, which is in hex and translates to 443 in decimal. SSL/HTTPS uses port 443.
