Question 1

• A network engineer notices that transmission
  rates of senders of TCP traffic sharply increase
  and decrease simultaneously during periods of
  congestion. Which condition causes this?
• global synchronization
• tail drop
• random early detection
• queue management algorithm

Answer A
Question 2

• Which three problems result from application
  mixing of UDP and TCP streams within a network
  with no QoS? (Choose three.)
• starvation
• jitter
• latency
• windowing
• lower throughput

Answer A, C, E
Question 3

• Which method allows IPv4 and IPv6 to work
  together without requiring both to be used for a
  single connection during the migration process?
• dual-stack method
• 6to4 tunneling
• GRE tunneling
• NAT-PT

3
Answer A
Question 4

• Which statement about the use of tunneling to
  migrate to IPv6 is true?
• Tunneling is less secure than dual stack or
  translation.
• Tunneling is more difficult to configure than
  dual stack or translation.
• Tunneling does not enable users of the new
  protocol to communicate with users of the old
  protocol without dual-stack hosts.
• Tunneling destinations are manually determined by
  the IPv4 address in the low-order 32 bits of
  IPv4-compatible IPv6 addresses.

Answer C
Question 5

• A network administrator executes the command
  clear ip route. Which two tables does this
  command clear and rebuild? (Choose two.)
• IP routing
• FIB
• ARP cache
• MAC address table
• Cisco Express Forwarding table
• topology table

Answer A, B
4
Question 6

• Which switching method is used when entries are
  present in the output of the command show ip
  cache?
• fast switching
• process switching
• Cisco Express Forwarding switching
• cut-through packet switching

Answer A
Question 7

• Which two actions must you perform to enable and
  use window scaling on a router? (Choose two.)
• Execute the command ip tcp window-size 65536.
• Set window scaling to be used on the remote host.
• Execute the command ip tcp queuemax.
• Set TCP options to "enabled" on the remote host.
• Execute the command ip tcp adjust-mss.

Answer A, B
Question 8

• Which three TCP enhancements can be used with TCP
  selective acknowledgments? (Choose three.)
• header compression
• explicit congestion notification
• keepalive
• time stamps
• TCP path discovery

5
F. MTU window
Answer B, C, D
Question 9

• A network administrator uses IP SLA to measure
  UDP performance and notices that packets on one
  router have a higher one-way delay compared to
  the opposite direction. Which UDP characteristic
  does this scenario describe?
• latency
• starvation
• connectionless communication
• nonsequencing unordered packets
• jitter

Answer A
Question 10

• Prior to enabling PPPoE in a virtual private
  dialup network group, which task must be
  completed?
• Disable CDP on the interface.
• Execute the vpdn enable command.
• Execute the no switchport command.
• Enable QoS FIFO for PPPoE support.
