Questions 21

An ArcGlS user is given a populated geodatabase thai contains a few highly accurate feature classes and a few feature classes that are less accurate.

When designing a geodatabase topology, which coordinate rank should be assigned to feature classes of less accuracy when compared with feature classes of higher accuracy?

Options:
A.

rank them higher so the coordinates of highly accurate feature classes are adjusted

B.

rank them lower so their coordinates are adjusted to highly accurate feature classes

C.

rank them the same as highly accurate feature classes so their coordinates are adjusted to weighted average

D.

rank them higher so their coordinates are not adjusted

Questions 22

An ArcGIS user creates a map showing the level of human Impact on the natural landscape. Major habitat types are shown with unique colors, and the level of disturbance for each habitat Is shown with a graduated symbol.

What is this type of map symbology?

Options:
A.

Multisymbol

B.

multivariate

C.

unique value many fields

D.

proportional symbol

Questions 23

AnArcGIS user is tasked with editing a layer containing a large number of features, using another layer thatis in a different coordinate a system as reference. The user adds the layers in ArcMap and starts an editsession. A warning message about editing data in a different coordinate system is displayed.

What is the most efficient way to edit the data to avoid potential distortion in the data?

Options:
A.

change the data frame's coordinate system to match the coordinate system of the layer being edited

B.

project the reference layer so the coordinate system matches with the one that needs to be edited

C.

georeference the reference layer and start a new edit session

D.

create a geodatabase topology with the two layers and add a rule so new data always snaps to thereference layer

Questions 24

An ArcGlS user adds an ESRl World Imagery service from ArcGlS Online to an empty Arc Map document.

The user then adds a polygon feature class representing national parks to the map.

The spatial reference of the national parks feature class is:

• Datum North American Datum 1927

• Linear units meters

• Protection Albers equal area

The user intends to digitize new national park boundaries using the features in the imagery.

What should the user avoid doing in the edit session?

Options:
A.

transforming the coordinate system of the national parks to match the Imagery from the Web service

B.

projecting the coordinate system of the imagery to match the national parks

C.

reprojecting the national park feature class and transforming the coordinate system to match the imagery from the Web service

D.

editing the park boundary laver without changing the original coordinate Systems

Questions 25

An ArcGlS user decides to use labels in a map document because the annotation appears pixelated as the user zooms from the reference scale

What Is a potential effect of this decision?

Options:
A.

Label placement will be controlled by the user

B.

Text placement will become static

C.

Labels will only draw at the reference scale

D.

The map will render more slowly

Questions 26

An ArcGIS user is tasked with publishing an image service out of a collection of rectified satellite imagery. Building the Image service definition results In a rotated dataset with large areas of NoData on the comers. The ArcGIS user needs to recompute the footprints to remove the large areas of NoData on the edges. Which method of recomputing footprints accomplishes this?

Options:
A.

by geometry

B.

by radiometry

C.

by clipping

D.

by related geometry

Questions 27

A layer tiding simple symbology is causing slow drawing performance at a scale where analysis needs to be conducted. Only certain features from this layer are necessary in order for analysis to be completed by the ArcGlS user

What can the user do to increase drawing performance?

Options:
A.

reproject the layer

B.

run the MXD doctor on the map document

C.

apply a definition query

D.

set a scale range to hide the layer
