Question 10

A network engineer executes the show ip flow export command. Which line in the output indicates that the send queue is full and export packets are not being sent ?

A) output drops

B) enqueuing for RP

C) fragmentation failures.

D) adjacency issues.

Question 11

A network engineer is asked to configure a "site-to-site" IPsec VPN tunnel. One of the last things that the engineer does is to configure an access list (access-list 1 permit any) along with the command ip nat inside source list 1 int s0/0 overload. Which functions do the two commands serve in this scenario ?

A) The command access-list 1 defines interesting traffic that is allowed through the tunnel.

B) The command ip nat inside source list 1 int s0/0 overload disables "many-to-one" access for all devices on a defined segment to share a single IP address upon exiting the external interface.

C) The command access-list 1 permit any defines only one machine that is allowed through the tunnel.

D) The command ip nat inside source list 1 int 0/0 overload provides "many-to-one" access for all devices on a defined segment to share a single IP address upon exiting the external interface

Question 12

A network engineer is configuring a solution to allow failover of HSRP nodes during maintenance windows, as an alternative to powering down the active router and letting the network respond accordingly. Which action will allow for manual switchingof HSRP nodes ?

B) Adjust the HSRP priority without the use of preemption.

C) Disable and enable all active interfaces on the active HSRP node.

D) Enable HSRPv2 under global configuration, which allows for maintenance mode.

Question 13

Which feature should the engineer use to gather the required information ?

A) SNMP

B) Cisco IOS EEM

C) NetFlow

D) Syslog

E) WCCP

Question 14

B) NetFlow output has been filtered by default.

C) Flow export version 9 is in use.

D) The command ip flow-capture fragment-offet has been enabled.
