1.Which three problems result from application mixing of UDP and TCP streams within a network with no
QoS? (Choose three.)
A. starvation
B. jitter
C. latency
D. windowing
E. lower throughput
Answer: ACE
Explanation:
It is a general best practice not to mix TCP-based traffic with UDP-based traffic (especially streaming
video) within a single service provider class due to the behaviors of these protocols during periods of
congestion. Specifically, TCP transmitters will throttle-back flows when drops have been detected.
Although some UDP applications have application-level windowing, flow control, and retransmission
capabilities, most UDP transmitters are completely oblivious to drops and thus never lower transmission
rates due to dropping. When TCP flows are combined with UDP flows in a single service provider class
and the class experiences congestion, then TCP flows will continually lower their rates, potentially giving
up their bandwidth to dropoblivious UDP flows. This effect is called TCP-starvation/UDP-dominance. This
can increase latency and lower the overall throughput. TCP-starvation/UDP-dominance likely occurs if
(TCP-based) mission-critical data is assigned to the same service provider class as (UDP-based)
streaming video and the class experiences sustained congestion. Even if WRED is enabled on the
service provider class, the same behavior would be observed, as WRED (for the most part) only affects
TCP-based flows. Granted, it is not always possible to separate TCP-based flows from UDP-based flows,
but it is beneficial to be aware of this behavior when making such application-mixing decisions. Reference:

2.Which statement about the use of tunneling to migrate to IPv6 is true?
A. Tunneling is less secure than dual stack or translation.
B. Tunneling is more difficult to configure than dual stack or translation.
C. Tunneling does not enable users of the new protocol to communicate with users of the old protocol
without dual-stack hosts.
D. Tunneling destinations are manually determined by the IPv4 address in the low-order 32 bits of IPv4-
compatible IPv6 addresses.
Answer: C
Explanation:
Using the tunneling option, organizations build an overlay network that tunnels one protocol over the other
by encapsulating IPv6 packets within IPv4 packets and IPv4 packets within IPv6 packets. The advantage
of this approach is that the new protocol can work without disturbing the old protocol, thus providing
connectivity between users of the new protocol. Tunneling has two disadvantages, as discussed in RFC
6144: Users of the new architecture cannot use the services of the underlying infrastructure.
Tunneling does not enable users of the new protocol to communicate with users of the old protocol
without dual-stack hosts, which negates interoperability.

3.Which two actions must you perform to enable and use window scaling on a router?(Choose two.)
A. Execute the command ip tcp window-size 65536.
B. Set window scaling to be used on the remote host.
C. Execute the command ip tcp queuemax.
D. Set TCP options to “enabled” on the remote host
E. Execute the command ip tcp adjust-mss.
Answer: AB
Explanation:
The TCP Window Scaling feature adds support for the Window Scaling option in RFC 1323, TCP
Extensions for High Performance. A larger window size is recommended to improve TCP performance in
network paths with large bandwidth-delay product characteristics that are called Long Fat Networks
(LFNs). The TCP Window Scaling enhancement provides that support. The window scaling extension in
Cisco IOS software expands the definition of the TCP window to 32 bits and then uses a scale factor to
carry this 32-bit value in the 16-bit window field of the TCP header. The window size can increase to a
scale factor of 14. Typical applications use a scale factor of 3 when deployed in LFNs. The TCP Window
Scaling feature complies with RFC 1323. The larger scalable window size will allow TCP to perform better
over LFNs. Use the ip tcp window-size command in global configuration mode to configure the TCP
window size. In order for this to work, the remote host must also support this feature and its window size
must be increased. Reference:
