QUESTION 1
What is the correct formula for determining the CIR?

A. CIR = Bc/Tc
B. CIR = Bc x Tc
C. CIR = Tc/Bc
D. CIR = Bc + Be
E. CIR = Tc/(Bc+Be)
F. CIR = (Bc+Be)/Tc

Answer: A

Explanation:
Committed Information Rate (CIR) – the rate the device will send at (on average) over a one
second period.
The default CIR when traffic-shaping is enabled on the interface is 56K. CIR is also referred to as
the “target rate”. Since the device is forced to send at the AR, it does not send all of the time
(within one second) Â in order to send an average amount of data that equals the CIR.
Minimum CIR (mincir) – the rate the service provider guarantees to accept. Theoretically, the
provider will set the DE bit for all traffic above this rate. Mincir is designed to be used in
conjunction with adaptive shaping. With adaptive shaping, the router will throttle down in the event
of congestion. The router will not throttle down below this value.
Committed Burst (Bc) – the number of committed bits allows to be sent during a given interval.
The device sends an average amount of traffic to achieve the CIR. The Bc value defaults to 1/8 of
the configured CIR for speeds below 650K. For speeds above that, it is roughly 1/16 of CIR.
Excess Burst (Be) – the number of non-committed bits the router is allowed to send above Bc
during the first interval (Tc). The amount of Be “credits” is derived from unused Bc credits in
previous intervals. There is no limit to how long Be can “store” unused Bc credits. It is a common
misconception that Be can only store credits from the previous interval or the previous second.
There is no default Be value.
Committed Rate Measurement Interval (Tc) – the time interval over whic Bc or Bc+Be can be
transmitted. The max value is 125 ms and the minimum value is 10 ms.
The Formula
CIR, Tc, and Bc are related mathematically by the following formula:
CIR = Bc/(Tc/1000) Notice the division of Tc by 1000 is used to convert milliseconds into seconds
– the common measurement of CIR and Bc.

QUESTION 2
DS-TE implementations on Cisco routers support which bandwidth pool(s) and class type(s)?
(Choose two.)

A. global pool only
B. subpool only
C. global pool and subpool
D. class-type 0 only
E. class-type 1 only
F. class-type 0 and class-type 1

Answer: C,F

Explanation:
Differential Service Tunnels
Differential Service Traffic Engineering (TE) is an extension of the regular MPLS Traffic
Engineering (MPLSTE) feature. Regular TE does not provide bandwidth guarantees to different
traffic classes. A single bandwidth pool (global pool) is used in regular TE that is shared by all
traffic. In order to support various class of service (CoS), the ability to provide multiple bandwidth
pools is required. These bandwidth pools then can be treated differently based on the requirement
for the traffic class using that pool.
In RSVP global and subpools reservable bandwidths are configured on a per interface basis to
accommodate TE tunnels on the node. Available bandwidth from all configured bandwidth pools is
advertised using Interior Gateway Protocol (IGP). RSVP is used to signal the TE tunnel with
appropriate bandwidth pool requirements.

QUESTION 3
Which field in the MPLS shim header is used to support different QoS markings?

A. IP precedence
B. DSCP
C. EXP
D. ToS

the packets flows that are destined to the router that is based on defined flow-type rates?

A. LLQ
B. LPTS
C. Committed Access Rate
D. Control Plane Policing
E. Management Plane Protection
F. NetFlow
G. ACL

Answer: B

Explanation:
Local Packet Transport Services (LPTS) maintains tables describing all packet flows destined for
the secure domain router (SDR), making sure that packets are delivered to their intended
destinations.
The Low Latency Queueing feature brings strict priority queueing to Class-Based Weighted Fair
Queueing (CBWFQ).

QUESTION 1
You create a Web Part by using Microsoft Visual Studio 2010. You need to execute SPDisposeCheck.exe before the Web Part is deployed. What should you do?

A. Configure a pre-deployment command line.
B. Configure SPDisposeCheck.exe as an external tool.
C. Change the configuration from Active (Debug) to Release.
D. Change the active deployment configuration to No Activation.

Answer: A

Explanation:

QUESTION 2
You have a SharePoint site collection. The root Web of the site collection has the URL http://intranet.
You plan to create a sandboxed solution that will contain a Web Part. The Web Part will display the title of the root Web.
You write the following code segment for the Web Part. (Line numbers are included for reference only.)
01 SPSite currentSite = new SPSite("http://intranet");
02
03 Label currentTitle = new Label();
04 currentTitle.Text = currentSite.RootWeb.Title;
You add the Web Part to a page in the root Web and receive the following error message: "Web Part Error: Unhandled exception was thrown by the sandboxed code wrapper's Execute method in the partial trust app domain: An unexpected error has occurred."
You need to prevent the error from occurring.
What should you do?

A. Add the following line of code at line 02: currentSite.OpenWeb();
B. Add the following line of code at line 02: currentSite.OpenWeb("http://intranet");
C. Change line 01 to the following code segment: SPSite currentSite = SPContext.Current.Site;
D. Change line 04 to the following code segment: currentTitle.Text = currentSite.OpenWeb().Title;

Answer: C

Explanation:
MNEMONIC RULE: "sandboxed = SPContext"
OpenWeb() method returns SPWeb object, so answers A and B are incorrect, since they assume OpenWeb()method doesn't return an object.
Answer D is incorrect for the same reason.
This constructor is allowed in sandboxed solutions. in that case, the value of the requestUrl parameter mustresolve to the parent site collection in which the sandboxed solution is deployed. If the value of the requestUrl parameter resolves to the URL of any other site collection, the constructor throwsan exception because a sandboxed solution is not allowed to access any SharePoint objects outside its hostingsite collection.

QUESTION 3
You are creating a Web Part that will be deployed as a sandboxed solution. You need to ensure that the Web Part can write debugging information to the SharePoint trace logs. Which class should the logging component inherit?

A. SPDelegate
B. SPLog
C. SPPersistedObject
D. SPProxyOperation

Answer: D

Explanation:
MNEMONIC RULE: "sandboxed solution needs SPProxyOperation"
You can implement your full-trust functionality in classes that derive from the SPProxyOperation abstract classand deploy the assembly to the global assembly cache. These classes expose a full-trust proxy that you cancall from within the sandbox environment.
Full-trust proxies can provide a useful way to expose logging and configuration functionality to sandboxedapplications.

QUESTION 4
You need to create a Web Part that will store and retrieve information for the current subsite. Which object should you use?

A. SPContext.Current.Site.RootWeb.AllProperties
B. SPContext.Current.Site.RootWeb.Configuration
C. SPContext.Current.Web.Configuration
D. SPContext.Current.Web.Properties

Answer: D

Explanation:
MNEMONIC RULE: "information is in Web.Properties" SPContext.Current.Web is SPWeb object.
Properties is the SPPropertyBag object with the metadata for the website. SPWeb.Properties Property http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spweb.properties.aspx

QUESTION 5
You create a SharePoint solution. You deploy the SharePoint solution by using Microsoft Visual Studio 2010. You need to prevent the Feature that is contained in the solution from being automatically activated when you deploy the solution. What should you configure in Visual Studio 2010?

A. the active deployment configuration
B. the build configuration
C. the pre-deployment command line
D. the startup item
