A technician is on the job for a small local government office in a small town. The office resides in a single-office building with a single floor. The technician needs to troubleshoot connection issues experienced throughout the system. Determine where the technician will find the termination points of the access layer switch ports.
Rack system
IDF
MDF
VPN Concentrator
MDF
The Main Distribution Frame (MDF) is a core level switching location where trunk links from Intermediate Distribution Frames (IDFs) and WAN circuits terminate. For a small network, there is no need for IDFs, the MDF terminates the access layer switch ports directly.
A network administrator is collecting configuration baselines by capturing Configuration Items (CI) and storing them in the Configuration Management Database (CMDB) available in the Configuration Management System software. The administrator’s next task is to identify the relationships between the various CIs and how they affect each other and the network. Describe the ideal method for capturing the relationships between CIs.
Use software tools, such as Lansweeper.
Correlate CI data with performance metrics.
Draw network diagrams.
Run a vulnerability scan.
Draw network diagrams.
Drawing diagrams to map the relationships between the various Configuration Items (CI) stored in the Configuration Management Database is the simplest and most efficient way to identify and organize the relationships between the CIs.
In reviewing network documentation during a large overhaul of their network, management of a growing Internet Service Provider (ISP) realize they must completely relabel their Main Distribution Frame (MDF) connections, rewrite network diagram maps, and re-document key information, such as Internet Protocol (IP) addresses and bandwidth. They must also add Intermediate Distribution Frames (IDFs) to their network infrastructure. Analyze the situation and demonstrate which forms of documentation need updating. (Select two)
Port location diagrams
Standard Operating Procedure (SOP)
Job logs
Physical diagram
Port location diagrams
Physical diagram
A port location diagram identifies how wall ports located in work areas are connected back to ports in a distribution frame or patch panel and then from the patch panel ports to the switch ports.
A physical (layer 1) diagram shows detailed information (such as location) about the physical assets in the network and the connections or cable links running between them.

When a change to configuration items is reactive, the change initiated is due to which of the following?
Internal forces within the organization
Forces outside of the org.
Request for Change (RFC)
Standard operating procedure
Forces outside of the organization
The need to change is often described either as reactive, where the change is forced on the organization, for instance, regulations or market forces.
A campus student in charge of administering the school network, relabeled ethernet cables after some changes to the network. The student notices that a cable originally going to Meeting Room B on the second floor of the administration building, now goes to Computer Lab A on the third floor. The student decides to relabel the cable. Determine which labeling is most fitting in terms of port naming conventions.
Meeting Room B, Second Floor
Floor Two Cable
AB01-02B-D01
AB01-03A-D01
AB01-03A-D01
A typical port naming convention is for alphanumeric identifiers for the building, telecommunications space, and port. In the example, AB01 means administrative building 1, 03A means floor 3, room A. The port is Data port 1, which has not changed.

A network administrator is working directly with programmers on a new project at a manufacturing plant. The project involves installing modules that a Linux server monitors, that sends “heartbeat” messages of the status of the press molds connected to the modules. Before the installation process, the programmers require the network administrator’s assistance establishing network performance baselines. Which of the following would NOT be a tool or method the administrator would use to institute performance baselines?
Access the server via command line and use the ifconfig terminal command to display IP information.
Test throughput by transferring several large files via multiple routes to test throughput and network efficiency.
Draw several network diagrams of physical and logical layers.
Use IP Flow Information Export (IPFIX) to monitor and analyze packet flow.
Access the server via command line and use the ifconfig terminal command to display IP information.

A large enterprise client asks a contracted technician to make hourly backups of an Influx database that is always open and continuously updated. The database is critical for hundreds of workers. Which of the following is the best method for accomplishing these backups?
- Establish an hourly full backup routine.
- Use Volume Shadow Copy or Samba to create hourly snapshots of the database host.
- Set up an hourly incremental backup.
- Institute a policy enforcing hourly differential backups.
Use Volume Shadow Copy or Samba to create hourly snapshots of the database host.
Snapshots are the best way to backup open files without errors. In Windows, snapshots can be taken on NTFS volumes by the Volume Shadow Copy Service (VSS).
A system has a network of ASICs (Application-Specific Integrated Circuits) computing nodes organized into a cluster for training Artifical Intelligence (AI) models. There are 64 devices running non-stop. In a period of 48 hours, two of the devices failed. Calculate the Mean Time Between Failures (MTBF) for the Service Level Agreement (SLA).
(64+48)/2=56
(64-48)2=32
(4864)/2=1536
(2*48)+64=160
(48*64)/2=1536
The MTBF (Mean Time Between Failures) is the total time divided by the number of failures. Therefore, 64 devices times 48 hours divided by two failures equals 1,536 hours, or 64 days. This indicates that on average, when following an individual device, it will fail in about 1536 hours or 64 days.
A Key Performance Indicator (KPI) is a network performance metric used to determine asset reliability. Which of the following is NOT an example of a KPI?
Mean Time to Failure (MTTF)
Mean Time to Repair (MTTR)
Mean Time Between Failures (MTBF)
Maximum Tolerable Downtime (MTD)
Maximum Tolerable Downtime (MTD)
Maximum Tolerable Downtime (MTD) is a metric that states the requirement for a business function. It is a goal, but is not a performance indicator.
