CCNP Route Network Principles

12 Questions

Question 1

Based on this FIB table, which statement is correct?

A) There is no default gateway.

B) The IP address of the router on FastEthernet is 209.168.201.1

C) The gateway of last resort is 192.168.201.1

D) The router will listen for all multicast traffic

Question 2

A network administrator checks this adjacency table on a router. What is a possible cause for this incomplete marking?

A) Incorrect ARP information

B) Incorrect ACL

C) Dynamic routing protocol failure.

D) Serial link congestion

Question 3

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?

A) global synchronization.

B) tail drop

C) random early detection

D) queue management algorithm

Question 4

Which three problems results 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

Question 5

Which method allows IPv4 and IPv6 to work together without requiring both to be used for a single connection during the migration process?

A) dual-stack method

B) 6 to 4 tunneling.

C) GRE tunneling

D) NAT-PT

Question 6

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.

Question 7

A network administrator executes the command clear ip route. Which two tables does this command clear and rebuild? (Choose two)

A) IP routing

B) FIB

C) ARP cache

D) MAC address table.

E) Cisco Express Forwarding table.

F) topology table.

Question 8

Which switching method is used when entries are present in the output of the command show ip cache ?

A) fast switching

B) process switching

C) Cisco Express Forwarding switching.

D) Cut-through packet switching.

Question 9

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

Question 10

Which three TCP enhancements can be used with TCP selective acknowledgements ? (Choose three)

A) header compression

B) explicit congestion notification.

C) Keepalive

D) time stamps

E) TCP path discovery

F) MTU window

Question 11

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 characteristics does this scenario describe ?

A) latency

B) starvation

C) connectionless communication

D) nonsequencing unordered packets.

E) jitter.

Question 12

Under which condition does UDP dominance occur ?

A) when TCP traffic is in the same class as UDP

B) when UDP flows are assigned a lower priority queue.

C) when WRED is enabled.

D) when ACLs are in place to block TCP traffic.
