Q52. Which statement is true about the PPP Session Phase of PPPoE?
A. PPP options are negotiated and authentication is not performed. Once the link setup is completed, PPPoE functions as a Layer 3 encapsulation method that allows data to be transferred over the PPP link within PPPoE headers.
B. PPP options are not negotiated and authentication is performed. Once the link setup is completed, PPPoE functions as a Layer 4 encapsulation method that allows data to be transferred over the PPP link within PPPoE headers.
C. PPP options are automatically enabled and authorization is performed. Once the link setup is completed, PPPoE functions as a Layer 2 encapsulation method that allows data to be encrypted over the PPP link within PPPoE headers.
D. PPP options are negotiated and authentication is performed. Once the link setup is completed, PPPoE functions as a Layer 2 encapsulation method that allows data to be transferred over the PPP link within PPPoE headers.
Answer: D
Explanation:
PPPoE is composed of two main phases:
Active Discovery Phase--In this phase, the PPPoE client locates a PPPoE server, called an access concentrator. During this phase, a Session ID is assigned and the PPPoE layer is established.
PPP Session Phase--In this phase, PPP options are negotiated and authentication is performed. Once the
link setup is completed, PPPoE functions as a Layer 2 encapsulation method, allowing data to be transferred over the PPP link within PPPoE headers.

Q53. A network engineer is trying to modify an existing active NAT configuration on an IOS router by using the following command:
(config)# no ip nat pool dynamic-nat-pool 192.1.1.20 192.1.1.254 netmask 255.255.255.0
Upon entering the command on the IOS router, the following message is seen on the console:
%Dynamic Mapping in Use, Cannot remove message or the %Pool outpool in use, cannot destroy
What is the least impactful method that the engineer can use to modify the existing IP NAT configuration?
A. Clear the IP NAT translations using the clear ip nat traffic * " command, then replace the NAT configuration quickly, before any new NAT entries are populated into the translation table due to active NAT traffic.
B. Clear the IP NAT translations using the clear ip nat translation * " command, then replace the NAT configuration quickly, before any new NAT entries are populated into the translation table due to active NAT traffic.
C. Clear the IP NAT translations using the reload command on the router, then replace the NAT configuration quickly, before any new NAT entries are populated into the translation table due to active NAT traffic.
D. Clear the IP NAT translations using the clear ip nat table * " command, then replace the NAT configuration quickly, before any new NAT entries are populated into the translation table due to active NAT traffic.

Q57. Which NetFlow component is applied to an interface and collects information about flows?
A. flow monitor
B. flow exporter
C. flow sampler
D. flow collector
Answer: A
Explanation:
Flow monitors are the NetFlow component that is applied to interfaces to perform network
traffic monitoring. Flow monitors consist of a record and a cache. You add the record to the flow monitor
after you create the flow monitor. The flow monitor cache is automatically created at the time the flow
monitor is applied to the first interface. Flow data is collected from the network traffic during the monitoring
process based on the key and nonkey fields in the record, which is configured for the flow monitor and
stored in the flow monitor cache. Reference: http://www.cisco.com/c/en/us/td/docs/ios/fnetflow/command/

Q58. Which two functions are completely independent when implementing NAT64 over NAT-PT? (Choose two.)
A. DNS
B. NAT
C. port redirection
D. stateless translation
E. session handling
Answer: A,B
Explanation:
Network Address Translation IPv6 to IPv4, or NAT64, technology facilitates communication
between IPv6-only and IPv4-only hosts and networks (whether in a transit, an access, or an edge
network). This solution allows both enterprises and ISPs to accelerate IPv6 adoption while simultaneously
handling IPv4 address depletion. The DNS64 and NAT64 functions are completely separated, which is
essential to the superiority of NAT64 over NAT-PT. Reference: http:// www.cisco.com/c/en/us/products/

Q59. 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
Answer: A
Explanation:
Explanation: Mixing TCP with UDP It is a general best practice to not mix TCP-based traffic with UDPbased
traffic (especially Streaming-Video) within a single service-provider class because of the behaviors
of these protocols during periods of congestion. Specifically, TCP transmitters throttle back flows when
drops are 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 because of dropping. When TCP flows are combined with UDP flows within a single
service-provider class and the class experiences congestion, TCP flows continually lower their
transmission rates, potentially giving up their bandwidth to UDP flows that are oblivious to drops. This
effect is called TCP starvation/UDP dominance. 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 because WRED (for the most part) manages congestion only
on TCP-based flows. Reference: http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/

Q60. For troubleshooting purposes, which method can you use in combination with the “debug ip packet” command to limit the amount of output data?
A. You can disable the IP route cache globally.
B. You can use the KRON scheduler.
C. You can use an extended access list.
D. You can use an IOS parser.
E. You can use the RITE traffic exporter.
Answer: C
Explanation:
The debug ip packet command generates a substantial amount of output and uses a substantial amount of
system resources. This command should be used with caution in production networks. Always use with the access-list command to apply an extended ACL to the debug output. Reference: http://www.cisco.com/c/en/us/support/docs/security/dynamic-multipoint-vpn-dmvpn/111976-dmvpn-troubleshoot-00.html
