QUESTION NO: 1
Scenario:
On CE 7 router, which statement is correct regarding the "QOS-POLICY policy map configurations?
A. The "QOS-POLICY is applied to the gi0/0 interface in the input direction
B. Traffic matched bythe"QOS-HTTP-1" class-map is shaped to an average is rate of 2560000
128000bps
C. Traffic matched bythe"QOS1-HTTP-2" class-map will be queued in the low-latency-queue which has a maximum bandwidth guarantee of 64000
D. Traffic matched by the "QOS-FTP-1" class-map can't use more than 256 Kbps under any condition
Answer: D
Explanation
# show policy-map
# show policy-map interface x/y
# show running-config policy-map

QUESTION NO: 2
When using the tunnel mpls traffic-eng path-option 1 explicit name test command in Cisco
MPLS TE tunnel configurations, the test explicit-path configuration will consist of a list of which values?
A. resource class affinity
B. IP address
C. MPLS label
D. tunnel endpoint
Answer: B
Explanation
tunnel mpls traffic-eng path-option
To configure a path option for a Multiprotocol Label Switching (MPLS) traffic engineering tunnel, use the tunnel mpls traffic-eng path-option command in interface configuration mode. To disable the specified path option, use the no form of this command.
tunnel mpls traffic-eng path-option number {dynamic | explicit {name path-name | path-number}}
[lockdown] no tunnel mpls traffic-eng path-option number {dynamic | explicit {name path-name
| path-number}} [lockdown]
Syntax Description
number = When multiple path options are configured, lower numbered options are preferred.
dynamic = Path of the LSP is dynamically calculated.
explicit = Path of the LSP is an IP explicit path.
name path-name = Path name of the IP explicit path that the tunnel uses with this option.
path-number = Path number of the IP explicit path that the tunnel uses with this option.
lockdown = (Optional) The LSP cannot be reoptimized.
Usage Guidelines
You can configure multiple path options for a single tunnel. For example, there can be several explicit path options and a dynamic option for one tunnel. Path setup preference is for lower (not higher) numbers, so option 1 is preferred.
Examples
The following example shows how to configure the tunnel to use a named IP explicit path:
Router(config-if)# tunnel mpls traffic-eng path-option 1 explicit name test

QUESTION NO: 3
Which three conditions can occur when metering traffic using a dual token bucket traffic policing QoS mechanism on Cisco routers? (Choose three.)
A. pass
B. burst
C. matched
D. exceed
E. violate
F. conform
Answer: D,E,F

QUESTION NO: 4
Which four pieces of information are stored for each prefix in the LFIB? (Choose four.)
A. incoming interface
B. next-hop IP address
C. outgoing interface
D. Layer 2 header rewrite information
E. outgoing label
F. local label
Answer: B,C,E,F
Explanation
Forwarding Labeled Packets
LSR forwards the packet based on:
Top Label value of the received packet
Corresponding entry in LFIB (LABEL <=> INTERFACE)
#show mpls forwarding-table - will show:
local label
outgoing label
prefix (network)
outgoing interface
next-hop
LSR expects packet to come with "top" label being "Local" (from show mpls forwarding-table).
If Outgoing label is "Aggregate", then that means that this is a summary route and more specific lookup is performed.
If LSR cannot find label/interface mapping in LFIB, then it drops the packet.
There are several "RESERVED" labels numbered from 0 to 15:
0 - explicit NULL - is used to preserver QoS info through EXP bits. It copies 'ip prec' or DiffServ.
1 - Router alert label - forces LSR to software switch the packet.
3 - Implicit NULL - this label is used for "connected" or "summary" routes. This way LSR signals it s neighbors to execute "POP label" operation on "connected" routes. It is called PHP, Penultimate
Hop Popping, and is used to make sure that LSR does not perform 2 lookups (label + ip).
14 - OEM alert label - is used for monitoring purpose.
In Cisco IOS, the default range is 16 through 100,000, but can be expanded by using "mpls label range" command.

QUESTION NO: 5
The Cisco IOS and IOS XE qos pre-classify command allows which kind of packet classification on IP packets that are encapsulated with GRE and IPsec?
A. allows for packets to be classified based on the packet payload before packet encryption
B. allows for packets to be classified based on the ToS byte values after packet encryption
C. allows for packets to be classified based on the packet payload after packet encryption
D. allows for packets to be classified based on the packet header parameters other than the ToS byte values after packet encryption
E. allows for packets to be classified based on the ToS byte values before packet encryption
Answer: E
Explanation
http://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a008017405e.shtml
The qos pre-classify command When packets are encapsulated by tunnel or encryption headers, QoS features are unable to examine the original packet headers and correctly classify the packets. Packets traveling across the same tunnel have the same tunnel headers, so the packets are treated identically if the physical interface is congested. With the introduction of the Quality of Service for Virtual
Private Networks (VPNs) feature, packets can now be classified before tunneling and encryption occur.
In this example, tunnel0 is the tunnel name. The qos pre-classify command enables the QoS for VPNs feature on tunnel0:
Router(config)# interface tunnel0
Router(config-if)# qos pre-classify
