Question 1

Which of the following best describes the relationship between the Tomcat [cmdb_ci_app_server_tomcat] table and the Application Server [cdmb_ci_app_server] table? (Choose two.)

ATomcat does not extend the Application Server table

BTomcat table extends the Application Server table

CTomcat table is a child of the Application Server table

DTomcat table is a parent of the Application Server table The mid.discovery.max_pattern_payload_size property defines the maximum overall size for the returned payload that comes from patterns. This property is set on the MID Server and applies to all patterns that run on that MID Server. If the payload size exceeds this limit, the pattern execution fails and an error message is logged in the ECC queue.The default value of this property is 10 MB1.

Answer : A, C

To create a custom horizontal pattern to discover an operating system that is not discovered by the base installation patterns, the following steps are necessary1:

Select a CI Type: This defines the type of configuration item (CI) that the pattern will discover and create or update in the CMDB. For an operating system, the CI Type should beOperating Systemor a subtype of it.

Select Infrastructure Pattern Type: This defines the type of pattern that will be used to discover the CI. For an operating system, the Infrastructure Pattern Type should beOperating Systemor a subtype of it.

Define the pattern logic: This consists of adding operations, variables, and conditions to the pattern to specify how the discovery process will identify and classify the operating system. For example, the pattern can use probes and sensors to query the target device for information such as name, version, vendor, etc.

Test and publish the pattern: This involves verifying that the pattern works as expected and does not cause any errors or conflicts with other patterns. Once the pattern is tested, it can be published and activated for discovery.

Question 2

Refer to the exhibit.

Based on the following images, which choice best describes what occurs if Discovery sets the name attribute of a discovered Windows Server CI to 'Windows1' and then Altiris discovery runs detecting 'Windows2' for the name attribute on the same CI?

AThe name of the CI stays 'Windows1'.

BThe name of the CI changes to 'Windows2'.

CThe name of the CI does not populate with either discovery.

DThe CI is not discovered because Discovery is not listed in either image.

Answer : B

In ServiceNow Discovery, the reconciliation process is governed by precedence rules. These rules determine which data source's information will be retained if there are conflicts when multiple sources discover the same CI. In this case, Altiris has a higher order of precedence (300) compared to ServiceNow (100), as seen in the ''Data Source Precedents'' section of the image. Therefore, if Altiris discovers 'Windows2' for the name attribute on the same CI after ServiceNow sets it to 'Windows1', the name will change to 'Windows2' due to Altiris's higher precedence.

Question 3

Which choice best describes what happens when, by default, duplicate CIs are detected during identification and reconciliation?

AA notification is sent to the CI owner.

BAn associated identification rule is created automatically.

CEach set of duplicate CIs is added to a de-duplication task.

DThe next discovery is stopped for the CI that is duplicated.

Answer : C

When Discovery or Service Mapping identifies a CI that matches an existing CI in the CMDB, it checks whether the CIs are duplicates or not. If they are duplicates, Discovery adds them to a de-duplication task, which is a record that groups duplicate CIs and allows you to review and remediate them. You can use the Duplicate CI Remediator wizard to merge, flag, retire, or delete the duplicate CIs. By default, Discovery does not send notifications, create identification rules, or stop the next discovery for duplicate CIs.

Question 4

A network device has both an SSH port and an SNMP port open. Discovery tries the SSH probe first and it fails. This triggers the SNMP probe, which succeeds. Discovery uses SNMP first for subsequent discoveries on that device.

What discovery functionality allows the above to happen?

AClassification

BCredential affinity

CMID Server affinity

DIP service affinity

Answer : B

Credential affinity is an association between a set of credentials and a device on your network. When Discovery or Orchestration first attempts to access a device, they try all available credentials until a valid one is found. Once a valid credential is found, it is recorded in thedscy_credentials_affinitytable, and further discovery processes rely on this information. If the credentials are modified or changed, the process will be repeated until a valid credential is found and updated in the same table. Credential affinity allows Discovery to use the most efficient and successful credential for each device, and avoid unnecessary credential failures.

Question 5

The CMDB contains which of the following record types? (Choose two.)

AModel

BConfiguration Item (CI)

CAsset

DRelation Type

Answer : B, D

The CMDB contains records of configuration items (CIs) and their relationships. A CI is any component that needs to be managed in order to deliver an IT service, such as a server, an application, or a user. A relation type defines the nature of the connection between two CIs, such as depends on, uses, or contains. A model is a template for a CI that defines its attributes and default values. An asset is a tangible or intangible resource that is tracked and managed by the organization, such as a laptop, a license, or a contract.

Question 6

Which choices are necessary to launch any pattern? (Choose two.)

ACI Classification

BCI Serial Number Attribute

CData Certification

DCI Type

Answer : A, D

To launch any pattern, you need to specify the CI classification and the CI type. The CI classification determines the table where the discovered CI is stored in the CMDB, and the CI type defines the specific attributes and relationships of the CI. For example, if you want to discover a Windows server, you need to select the CI classification ascmdb_ci_win_serverand the CI type asWindows Server. These choices are mandatory for any pattern, as they enable Discovery to identify and classify the CIs correctly.

Question 7

CI identifiers can be viewed under which of the following?

ADiscovery Dashboard

BCI Class Manager

CProcess Handlers

DProcesses and Classification

ECI record

Answer : E

CI identifiers can be viewed under the CI record1.A CI identifier is a set of attributes that uniquely identify a CI of a specific class2.CI identifiers are used by the identification and reconciliation engine (IRE) to match incoming data with existing CIs in the CMDB3.CI identifiers can be viewed and edited in the CI record by clicking the Identification Information related link1.
