本番までもう時間はない。

今からどうがんばっても技術的、知識的な面から言えば2週間後と今では差はほとんどない。

だから俺は本番の8時間において誰にも負けない気持ちで臨む!

1月11日の1日のみ年に一度だけの本気を出します。

SP QoS quiz !

Q1.
How many bits in the IP header can be used for QoS?

Q2.
How many AF classes exits?

Q3.
Name the 3 MPLS DffServ models

Q4.
What it the difference between the Pipe and Short Pipe models?

Q5.
What is the interface command to encapsulate all IP packets with an explicit NULL label?

Q6.
What is TOS reflection?

Q7.
What feature is used in Cisco IOS to alter the EXP bits?

Q8.
What is the problem with PHP and QoS?

Q9.
What is the solution to the problem in quesion 8?

Q10.
On which labels can you change the EXP bits value?

-----------------------------------------

A1.
3 bits for IP precedence or 6 bits for DSCP

A2.
4

A3.
Uniform model, Pipe model and Short pipe model

A4.
Pipe model using the LSP DiffServ information to forward packets on egress LSR
Short pipe model useing the Tunnel DiffServ information to forward packets on egress LSR

A5.
mpls ip encapsulate explicit-null

A6.
The default behavior of copying the precedence value of an IP packet to the EXP bits of all imposed labels

A7.
MQC

A8.
the EXP bits value is not copied to the newly exposed MPLS label or precedence/DiffServ bits in the IP header, if the packet becomes unlabeled

A9.
explicit NULL label or qos-group

A10.
the top label and the pushed label

Internet Expert has released CCIE SP Core Knowledge Simulation today.

I bought it soon and tried some questions they provided,  and I realized that I still lack of fundamentals about some sp track related technologies.

For improving my knowledge, I decide to use the simullation tool to do more preparation for oeq this weekend !

Now the number of questions in the simulation is 75, but within a few days will over 200 they talked on the ie blog. I wish more and more question would added before my ccie sp lab in sydeny.


You can see some sample questions on their pages.

TE quiz, here we go !

Q1.
Name the advanteges of MPLS traffic engineering

Q2.
What are the components of MPLS traffic enginnering?

Q3.
What are the attributes of the links enablefor traffic enginnering?

Q4.
Name the 6 ways how you can forward ip traffic onto a TE tunnel

Q5.
Name 4 kind of path options you can specify

Q6.
When you have an MPLS VPN network and TE tunnels that do not always have the PE routers as head/tail end routers, what do you need to have?

Q7.
What is the LSR that is the head end router of a backup tunnel called?

Q8.
Why do you need a link-state routing protocol for MPLS TE?

Q9.
What is the feature called that has the IGP advertise TE tunnels as links?

Q10.
How does the head end LSR of a TE tunnel knows that the tunnel is fast rerouted over a backup tunnel?

------------------------------------------

A1.
- sttering traffic so that all links in the network are used optimally
- routing traffic around hostspots in the network
- fast rerouting traffic around link and node failures

A2.
- OSPF or IS-IS with TE extensions enalbed
- RSVP
- Link attributes
- TE tunnel attributes

A3.
- maximum reservable bandwidth
- attribute flags
- TE metric

A4.
- static route
- policy-based routing
- forwarding adjacency
- autoroute announce
- direct mapping of AToM traffic onto TE tunnels
- CBTS

A5.
- explicit
- explicit with exclude address
- explicit with loose next address
- dynamic

A6.
- LDP enabled on the links
- LDP targeted session on the TE tunnel if the tail end router is a P router

A7.
the point of local repair(PLR)

A8.
to know the attributes and available bandwidth of all links

A9.
forwarding adjacency

A10.
receiving a PathErr message from the PLR, indicating that local repair is active
