Question 2.
What makes the DiffServ model more scalable than the IntServ model? (Choose all that apply.)

A. DiffServ makes use of per-aggregate QoS instead of per-flow QoS.

B. No hop-by-hop signaling uses per-hop behavior
C. This is a feature of both models Sources: Cisco IP QoS Introduction
http://www.cisco.com/en/US/tech/ ITK5 43/ ITK7 66/technologies_white_paper09186a00800a3e2f.shtml

E. This is a feature of policing

Explanation:

Question 4.
Study the Exhibit below carefully:
Router# show interfaces hssi 0/0/0 rate-limit
Hssi0/0/0 45Mbps to R1
Input
matches: all traffic
params: 20000000 bps, 24000 limit, 24000 extended limit
conformed 8 packets, 428 bytes; action: transmit
exceed 0 packets, 0 bytes; action: drop
last packet: 8680ms ago, current burst: 0 bytes
last cleared 00:03:59 ago, conformed 0 bps, exceed 0 bps
Output
matches: all traffic
params: 20000000 bps, 24000 limit, 24000 extended limit
conformed 0 packets, 0 bytes; action: transmit
exceed 0 packets, 0 bytes; action; drop
last packet: 8680ms ago, current burst: 0 bytes
last cleared 00:03:59 ago, conformed 0 bps, exceed 0 bps
According to the exhibit, the router has been configured with Committed Access Rate (CAR) to rate limit traffic.

What data rate has the traffic been limited to?

A. 192 Kbps
B. 2400 Kbps
C. 4,5 Mbps
D. 20 Mbps
E. 40 Mbps

Answer: D

Explanation:
 

In the configuration example, CAR is applied on the input and output of a customer interface on the provider edge router. Traffic is policed to 256 Kbps on input and output, with some bursting allowed. All exceeding traffic is dropped at the provider edge. The result of the configuration is that traffic to and from the customer is limited to the average rate of approximately 256kbps (256000 in the configuration) with sustained bursts of approximately 32kbps (4kBps or 4000 in the configuration). Initial bursts at line speed can last up to 3 seconds because the token bucket can hold up to 96000 tokens (bytes) which equals 768000 bits (3 x 256000 bits).

Question 5:
The newly appointed ITCertKeys trainee technician wants to know which type of software queuing mechanism is Frame Relay Traffic Shaping implemented with on the physical interface. 

What will your reply be?

A. Priority Queuing (PQ)
B. Custom Queuing (CQ)
C. FIFO
D. Weighted Fair Queuing (WFQ)
E. IP Real Time Transport Protocol (RTP) Priority

Answer: D

Explanation:
 
Works on any (sub) interface type  
Shapes traffic on that (sub)interface basis
Can use any physical interface queuing (FIFO, PQ, CQ or WFQ)
Only uses WFQ as the shaping queue (that is, on the input of the shaper)
In contrast, Frame Relay Traffic Shaping:
Works only on Frame Relay (sub) interfaces
Shapes traffic inside individual FR Virtual Circuits
Only permits WFQ as the physical interface queuing method
Can use any queuing method as the shaping queue (that is, on the input of the shaper)
Source: Cisco IP QoS Traffic Shaping and Policing, Page 4-47

Question 6.
Why is it beneficial to make use of Enhanced LMI (ELMI) on Cisco networks?

A. ELMI is responsible for providing virtual provisioning tools at the edge of the Frame Relay 
    network.
B. ELMI permits routers to dynamically download QoS information from Cisco switches for use in 
    traffic shaping or for congestion management purposes.
C. ELMI provides the router the ability to use additional QoS tools including rate limiting with CAR 
    and the Modular QoS Command Line Interface (MQC).
D. ELMI allows the router to deliver packets at the line rate of the Frame Relay interface, 
    regardless of the condition of the Frame Relay network.

Answer: B

Explanation:
 

Source: Cisco IP QoS Traffic Shaping and Policing, Page 4-58

Question 7. 
Which of the following statements are true when you compare DSCP and IP Precedence to each other? (Choose all that apply.)

A. DSCP is backwards compatible with IP Precedence.
B. DSCP cannot be easily mapped into QoS because of its expanded classification options.
C. DSCP is more granular the IP Precedence, since more marking combinations are available.
D. DSCP appears stubby when compared IP Precedence, since devices make use of DSCP as 
    defined in RFC exclusively.
E. DSCP is 6 bits long and IP Precedence is 3 bits long.
F. DSCP is more restrictive than IP Precedence, since devices are only allowed to use DSCP as 
    defined in RFCs.

Answer: A, C, E

Explanation:
A)DSCP is backward compatible with IP Precedence (Class Selector Code point, RFC 1812) but not with the ToS byte definition from RFC 791 ("DTR" bits) Reference: Introduction to IP QoS (Course) p.45

Question 8.
Which MQC command would you use to perform marking properly?

A. precedence 5
B. ip precedence 5
C. set ip precedence 5
D. set ip mark precedence 5
E. mark ip precedence 5

Answer: C

Explanation:
IP precedence is encoded into the three high-order bits of the ToS field in the IP header. It supports eight classes of which two are reserved and should not be used for user-defined classes (IP precedence 6 and 7). IP precedence 0 is the default value and is usually used for the best-effort class. The set ip precedence command marks packets of a class with the specified precedence value. 

Reference: 
Introduction to IP QoS (Course) p.9-104

Question 9.
Which of the following statements aptly describes a network well designed for QoS?

A. Packets are classified at each router, based on as many detail as possible, typically using 
    extended IP ACLs to match the packets for classification.
B. Packets are classified at each router, based on socket address only, typically using extended 
    IP ACLs to match the packets for classification.
C. Packets are classified and marked, close to the edge of the network. The packets are treated 
    differently based on this marking at the routers in the middle of the network.
D. Packets are classified based on different parameters, but close to the edge of the network. 
    The packets are automatically characterized based on flow at the routers.
E. Packets are classified based on socket address, at the router closest to the source of the 
    traffic. The packets are automatically characterized based on flow at the routers.

Answer: C

Explanation:
To achieve the same level of quality in both directions the packets going to and coming from the customer network must first be classified and marked.
Classification and marking packets going to the customer network is a more difficult task because:
1) Classifying and marking must be performed on all edge routers.
2) Classifying and marking requires the identification of the customer network. Using PBR, CAR, CB-Policing or CB-Marking does not scale because it involves the use of access lists (this is especially difficult if customer networks are dynamically learned via BGP).

Reference: 
Introduction to IP QoS (Course) p.2-35

Question 10.
The newly appointed ITCertKeys trainee technician wants to know which bit in the ATM header can be marked by the Class Based Marker to extend IP QoS policy into an ATM network. 

What will your reply be?

A. DE
B. PTI
C. FECN
D. CLP
E. BECN

Answer: D

Explanation:
 

The ATM CLP Setting feature somewhat allows users to extend their IP QoS policies into an ATM network by setting the ATM CLP bit in ATM cells based on the IP Precedence value of the packets being sent. As congestion occurs in the ATM network, cells with the CLP bit set are more likely to be dropped, resulting in improved network performance for high priority traffic and applications. The set atm-clp command marks packets of a class with the ATM CLP bit as a part of an input or output policy.
