質問 # 66
On the ECC Queue, sensor records have a Queue value of ___________ and probe records have a Queue value of ___________.
- A. started, ready
- B. output, input
- C. input, output
- D. ready, started
正解：B
解説：
On the ECC Queue, sensor records have a Queue value of output and probe records have a Queue value of input. The ECC Queue is the connection point between the instance and the MID Server, and it displays the input and output messages from and to the MID Server1. A probe is a message that the instance sends to the MID Server to request information from a device or application2. A sensor is a script that the MID Server runs to process the results returned by the probe3. When a probe is created, it is inserted into the ECC Queue with a Queue value of input, which means that it is waiting to be picked up by the MID Server4. When a sensor is created, it is inserted into the ECC Queue with a Queue value of output, which means that it is waiting to be processed by the instance.

質問 # 69
A Discovery Schedule contains a /24 subnet IP Range and a Shazzam batch size of 5000. How many times will a Shazzam probe be launched during discovery?
- A. 0
- B. 1
- C. 2
- D. 3
正解：B
解説：
A /24 subnet IP Range means that there are 256 possible IP addresses in the range, from 0 to 255. A Shazzam batch size of 5000 means that Discovery will send 5000 ICMP packets at a time to scan the IP addresses.
Therefore, Discovery will launch the Shazzam probe once for every 5000 IP addresses in the range, or 256 /
5000 = 0.0512 times. Since the number of times must be an integer, Discovery will round up to 1 and launch the Shazzam probe once. However, since the Shazzam probe is launched for each MID Server that is assigned to the Discovery Schedule, the actual number of times will depend on how many MID Servers are available.
If there are N MID Servers, then the Shazzam probe will be launched N times, each sending 5000 ICMP packets to the same IP range. Therefore, the total number of times that the Shazzam probe will be launched during discovery is N * 1 = N.

質問 # 70
SNMP Credentials require which of the following?
- A. read community strings
- B. write community strings
- C. usernames
- D. port 135 access
正解：A
解説：
SNMP credentials are used by Discovery to communicate with devices that support the Simple Network Management Protocol (SNMP). SNMP credentials do not include a user name, just a password, called the community string. The default read-only community string for many SNMP devices is public, and Discovery will try that automatically. Enter the appropriate SNMP credentials if they differ from the public community string1.

Which of the following choices explain differences between Service Mapping and Discovery? (Choose two.)
- A. Discovery addresses inventory-related use-cases, while Service Mapping allows for the creation of accurate maps of application service topologies.
- B. Discovery requires agent installation to find hardware devices, Service Mapping requires agents for software.
- C. Discovery finds applications and devices on your network, Service Mapping monitors those devices.
- D. Discovery utilizes IP address ranges for initial discovery, Service Mapping uses entry points.
正解：A、D
解説：
Discovery and Service Mapping are both products that help to identify and map the IT infrastructure and services in an organization. However, they have different approaches and objectives. Discovery uses IP address ranges as the starting point for finding devices and applications on the network, and then runs probes and sensors to collect information and classify them. Discovery focuses on inventory-related use-cases, such as asset management, configuration management, and compliance. Service Mapping uses entry points, such as URLs or host names, as the starting point for mapping business services and their dependencies. Service Mapping runs patterns, which are sequences of operations that follow the traffic connections between devices and applications, and then creates a service map that shows the logical and semantic relationships. Service Mapping focuses on service-related use-cases, such as service availability, impact analysis, and root cause analysis12.

質問 # 77
When designing steps with operations requiring variables, it is best practice to do what?
- A. always use scalar variables
- B. hard core variables
- C. design for a static environment
- D. query targets for variables
正解：D
解説：
When designing steps with operations requiring variables, it is best practice to query targets for variables1.
This allows you to dynamically obtain the values of the variables from the target devices, rather than hard coding them or using scalar variables that may not reflect the current state of the target. Querying targets for variables also enables you to design for a dynamic environment, where the target configuration may change over time.

質問 # 78
Which choice represents the three best ways of extending Discovery?
- A. Orchestration, Classifiers, Probes & Sensors
- B. Classifiers, Probes & Sensors, Discovery Patterns
- C. Fingerprinting, Classifiers, Discovery Patterns
- D. Orchestration, Classifiers, Discovery Patterns
- E. Classifiers, Fingerprinting, Probes & Sensors
正解：B
解説：
ServiceNow Discovery can be extended in three main ways: Classifiers, Probes & Sensors, and Discovery Patterns. Classifiers are used to identify the type of device or application that is being discovered, based on the information returned by a probe. Probes are commands or scripts that are executed on the target device or application to collect data. Sensors are scripts that process the data collected by probes and create or update configuration items (CIs) in the CMDB. Discovery Patterns are graphical representations of the discovery process that can be customized or created to discover specific types of devices or applications, using classifiers, probes, and sensors as building blocks.

質問 # 79
A discovery runs against a Windows Server returning the following attribute values for the first time:
name = WindowsSN1 serial_number = 12321
A subsequent discovery is ran against a different Windows Server returning the following attribute values:
name = WindowsSN2
serial_number = 12321
With only base system CI Identifiers configured, which of the following is true?
- A. A Windows Server CI is created, then updated with WindowsSN1 as the name.
- B. Two Windows Sewer CIs are created, with WindowsSN1 AND WindowsSN2 for names.
- C. A Windows Server CI is created, then updated with WindowsSN2 as the name.
- D. Two Windows Server CIs are created, without serial_number values.
正解：B
解説：
According to the ServiceNow Discovery documentation, the base system CI Identifiers for Windows Server class are name and serial_number. These are the attributes that Discovery uses to uniquely identify a Windows Server CI. If both attributes match an existing CI, Discovery updates that CI. If only one attribute matches, Discovery creates a new CI. If neither attribute matches, Discovery also creates a new CI. In this scenario, the serial_number is the same for both Windows Servers, but the name is different. Therefore, Discovery will create two separate CIs, one with WindowsSN1 as the name and one with WindowsSN2 as the name.

質問 # 80
For CMDB Health, relationships can be which of the following choices? (Choose three.)
- A. Duplicate
- B. Stale
- C. Recommended
- D. Required
- E. Orphan
正解：A、B、E
解説：
CMDB Health measures the quality of the data in the CMDB by testing it against predefined rules and metrics. One of the categories of these rules is Correctness, which tests the data against data integrity rules such as identification rules, orphan CI rules, and stale CI rules1. These rules help identify and flag the existing CMDB relationships that are not compliant with the suggested relationships2.
* Duplicate relationships are those that have more than one relationship of the same type between the same two CIs3. For example, if a server CI has two relationships of type "Depends on" with the same network CI, it is a duplicate relationship.
* Stale relationships are those that have not been updated for a specified period of time3. For example, if a server CI has a relationship of type "Runs on" with a virtual machine CI that has not been discovered for more than 60 days, it is a stale relationship.
* Orphan relationships are those that are missing a defined relationship within the CMDB3. For example, if a server CI has no relationship of type "Depends on" with any network CI, it is an orphan relationship.
