Question: 21

When you use tile layer, how does the map cache server provide correct results? Identify two correct statements.

A. When an end-user application asks for a region, the map cache server generates an image from the defined map.
B. The map cache server returns the tiles available in the tile cache, and generates new tiles if they are not yet in the cache.
C. Using the mesh code, the map cache server identifies a list of tiles that need to be retrieved by the end-user application.
D. MapViewer cannot give you local tiles and will always connect to an external tile cache server.

Answer: B,C

Explanation:
B:When the map tile server receives a map image tile request, it first checks to see if the requested tile is already cached. If the tile is cached, the cached tile is returned to the client. If the tile is not cached, the map tile server fetches the tile into the cache and returns it to the client. Tiles can be fetched either directly from the MapViewer map rendering engine or from an external Web map services provider.
C: The map tile server is a map image caching engine that caches and serves pregenerated, fixed-size map image tiles. It is implemented as a Java servlet that is part of the MapViewer server. The map tile server accepts requests that ask for map image tiles specified by tile zoom level and tile location (mesh code), and it sends the requested tiles back to clients.
Note:The map tile server (map image caching engine) automatically fetches and caches map image tiles rendered by Oracle MapViewer or other Web-enabled map providers. It also serves cached map image tiles to the clients, which are Web applications developed using the Oracle Maps client API. The clients can then automatically stitch multiple map image tiles into a seamless large map. Because the map image tiles are pregenerated and cached, the application users will experience fast map viewing performance.

Question: 22

Identify two correct ways to define Spatial metadata.

A. Metadata is filled inALL_SDO_GEOM_METADATAby the MDSYS user for all database layers.
B. Metadata is filled inUSER_SDO_GEOM_METADATAto define boundaries for each layer.
C. Metadata defines the coordinate system and indirectly associates units to layers.
D. Metadata is automatically filled in when you create spatial indexes and takes the footprint of layers as default boundaries.

Answer: A,B

Question: 23

Which statement is true about the networks managed by the Oracle Spatial Network Data Model?

A. A link connects two or more nodes.
B. In a directed network, all links can be traversed in both directions.
C. A link can have the same node as start end nodes.
D. A node must be connected to at least two links.

Answer: C

Question: 24

Which statement correctly defines the corresponding Open Geospatial Consortium (OGC) Web Services standards?

A. Web Map Service (WMS) enables browsing and querying against catalog servers.Web Feature Service (WFS) enables geocoding, routing, and usage of mapping and directory services.OpenGIS Location Service (OpenLS) enables access, search, and modification of geospatial features.Catalog Service for the Web (CSW) enables requests and delivery of maps.
B. CSW enables browsing and querying against catalog servers.WMS enables access, search, and modification of geospatial features.OpenLS enables geocoding, routing, and usage of mapping and directory services.WFS enables requests and delivery of maps.
C. WFS enables access, search, and modification of geospatial features.CSW enables browsing and querying against catalog servers.WMS enables requests and delivery of maps.OpenLS enables geocoding, routing, and usage of mapping and directory services.
D. WFS enables access, search, and modification of geospatial features.CSW enables browsing and querying against catalog servers.WMS enables requests and modification of maps.OpenLS enables geocoding, routing, and usage of mapping and directory services.

Answer: C

Explanation:
VMS:The OpenGIS Web Map Service Interface Standard (WMS) provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed. The response to the request is one or more geo-registered map images (returned as JPEG, PNG, etc) that can be displayed in a browser application. The interface also supports the ability to specify whether the returned images should be transparent so that layers from multiple servers can be combined or not.
CSW: Catalogue services support the ability to publish and search collections of descriptive information (metadata) for data, services, and related information objects. Metadata in catalogues represent resource characteristics that can be queried and presented for evaluation and further processing by both humans and software. Catalogue services are required to support the discovery and binding to registered information resources within an information community.
WFS: The Web Feature Service Interface Standard (WFS) provides an interface allowing requests for geographical features across the web using platform-independent calls.
OpenLS: The OpenGIS Open Location Services Interface Standard (OpenLS) specifies interfaces that enable companies in the Location Based Services (LBS) value chain to “hook up” and provide their pieces of applications such as emergency response (E-911, for example), personal navigator, traffic information service, proximity service, location recall, mobile field service, travel directions, restaurant finder, corporate asset locator, concierge, routing, vector map portrayal and interaction, friend finder, and geography voice-graphics. These applications are enabled by interfaces that implement OpenLS services such as a Directory Service, Gateway Service, Geocoder Service, Presentation (Map Portrayal) Service and others.

Question: 25

The match mode for a geocoding operation determines how closely the attributes of an input address must match the data stored in the geocoder schem
a. Which MATCHMODE attribute would you use so that the geocoder can deliver results despite any discrepancies in the input address?
A. RELAX_ALL
B. EXACT
C. RELAX_BASE_NAME
D. DEFAULT
E. Null

Answer: D

Explanation:
DEFAULT is equivalent to RELAX_POSTAL_CODE, in which the postal code (if provided), base name, house or building number, and street type can be different from the data used for geocoding.
IncorrectAnswers:
A, E: There are no match modes named RELAX_ALL or NULL.
B:Exact: All attributes of the input address must match the data used for geocoding.
C:RELAX_BASE_NAME:The base name of the street, the house or building number, and the street type can be different from the data used for geocoding. For example, if Pleasant Valley is the base name of a street in the data used for geocoding, Pleasant Vale would also match as long as there were no ambiguities or other matches in the data.
