right.
Cisco 400-101 question 1


Question No : 2 - Topic 1

Which statement about MSS is true?

A. It is negotiated between sender and receiver.
B. It is sent in all TCP packets.
C. It is 20 bytes lower than MTU by default.
D. It is sent in SYN packets.
E. It is 28 bytes lower than MTU by default.


Question No : 3 - Topic 1

Which statement is true regarding the UDP checksum?

A. It is used for congestion control.
B. It cannot be all zeros.
C. It is used by some Internet worms to hide their propagation.
D. It is computed based on the IP pseudo-header.


Question No : 4 - Topic 1

Refer to the exhibit.
Cisco 400-101 question 4
Your network is suffering excessive output drops. Which two actions can you take to
resolve the problem? (Choose two.)

A. Install a switch with larger buffers.
B. Configure a different queue set.
C. Reconfigure the switch buffers.
D. Configure the server application to use TCP.
E. Update the server operating system.


Question No : 5 - Topic 1

Drag and drop the fragmentation characteristics on the left to the corresponding protocol on
the right.
Cisco 400-101 question 5


Question No : 6 - Topic 1

Which two packet types does an RTP session consist of? (Choose two.)

A. TCP
B. RTCP
C. RTP
D. ICMP
E. BOOTP
F. ARP


Question No : 7 - Topic 1

Which two mechanisms can be used to eliminate Cisco Express Forwarding polarization?
(Choose two.)

A. alternating cost links
B. the unique-ID/universal-ID algorithm
C. Cisco Express Forwarding antipolarization
D. different hashing inputs at each layer of the network


Question No : 8 - Topic 1

What is a cause for unicast flooding?

A. Unicast flooding occurs when multicast traffic arrives on a Layer 2 switch that has directly connected multicast receivers.
B. When PIM snooping is not enabled, unicast flooding occurs on the switch that interconnects the PIM-enabled routers.
C. A man-in-the-middle attack can cause the ARP cache of an end host to have the wrong MAC address. Instead of having the MAC address of the default gateway, it has a MAC address of the man-in-the-middle. This causes all traffic to be unicast flooded through the man-in-the-middle, which can then sniff all packets.
D. Forwarding table overflow prevents new MAC addresses from being learned, and packets destined to those MAC addresses are flooded until space becomes available in the forwarding table.


Question No : 9 - Topic 1

Which option is the most effective action to avoid packet loss due to microbursts?

A. Implement larger buffers.
B. Install a faster CPU.
C. Install a faster network interface.
D. Configure a larger tx-ring size.


Question No : 10 - Topic 1

Refer to the exhibit.
Cisco 400-101 question 10
While troubleshooting high CPU utilization of a Cisco Catalyst 4500 Series Switch, you
notice the error message that is shown in the exhibit in the log file.
What can be the cause of this issue, and how can it be prevented?

A. The hardware routing table is full. Redistribute from BGP into IGP.
B. The software routing table is full. Redistribute from BGP into IGP.
C. The hardware routing table is full. Reduce the number of routes in the routing table.
D. The software routing table is full. Reduce the number of routes in the routing table.


Question No : 11 - Topic 1

Which two solutions can reduce UDP latency? (Choose two.)

A. fast retransmission
B. fast recovery
C. fast start
D. low-latency queuing
E. IP service level agreements
F. congestion-avoidance algorithm


Question No : 12 - Topic 1

Drag and drop the argument of the ip cef load-sharing algorithm command on the left to the
function it performs on the right.
Cisco 400-101 question 12


Question No : 13 - Topic 1

A TCP/IP host is able to transmit small amounts of data (typically less than 1500 bytes), but
attempts to transmit larger amounts of data hang and then time out. What is the cause of
this problem?

A. A link is flapping between two intermediate devices.
B. The processor of an intermediate router is averaging 90 percent utilization.
C. A port on the switch that is connected to the TCP/IP host is duplicating traffic and sending it to a port that has a sniffer attached.
D. There is a PMTUD failure in the network path.


Question No : 14 - Topic 1

C. The fragment header is 32 bits long.
D. The identification field is 64 bits long.
E. The MTU must be a minimum of 1280 bytes.
F. The fragment header is 48 bits long.
