Module 5 / Unit 1 / Network Site Management Flashcards
What would be a typical use of an IDF?
To cross-connect backbone cabling in a multi-building (campus) network. The Intermediate Distribution Frame introduces a hierarchy of cable organization between the Main Distribution Frame and horizontal crossconnects.
What is a 110 block?
A particular type of Insulation Displacement Connector (IDC) used to terminate solid cabling at the back of a wall port or patch panel.
In terms of day-to-day tasks, what demonstrates that effective configuration management procedures are in place
Job logs and Standard Operating Procedures (SOPs) to control and document configuration and troubleshooting work.
In terms of day-to-day tasks, what demonstrates that effective configuration management procedures are in place?
Job logs and Standard Operating Procedures (SOPs) to control and document configuration and troubleshooting work.
What is the difference between physical and logical schematics?
A logical schematic shows the topology of the network in abstract (such as IP networks); a physical schematic shows the locations of components and their IDs.
You are analyzing a network schematic and notice the following icon - What does it represent?
A router.
True or false? Rack units are sold in models of varying width
False - 19” width is standard while the height varies in “U” units of 1.75”.
You are working at a telecommunications point and notice that the cables in one patch panel are all red while the ones in another are all blue. What, if anything, does this represent?
The TIA 606 Administration standard recommends the use of red colorcoding for telephone links and blue for data links to the work area (horizontal cabling).
What type of door access control would allow entry based on the possession of a cryptographic smart card?
Proximity reader.
What technology could be used to provision security cameras without having to provide a separate circuit for electrical power?
IP cameras could be powered over data cabling using Power over Ethernet (PoE).
What type of security control provisions resources and procedures to cope with major incidents?
A Disaster Recovery Plan (DRP).
What is MTBF and why is it associated with a “bathtub curve”?
Mean Time Between Failures - the bathtub curve is a plot of instances of failure over time and tends towards a “bathtub” shape because failures are more likely early or late in the service life of an appliance than in the middle.
A server is equipped with 4 Ethernet interfaces and you want to aggregate them to a single interface. What feature must the switch support?
Port bonding / Link Aggregation Control Protocol (LACP [IEEE 802.3ad / 802.1ax]).
What technologies can be used to make network infrastructure fault tolerant?
Redundancy and failover needs to be provided at all levels: power, cabling / adapter teaming, switching, routing, and name services / addressing. Cluster services and load balancers can be deployed to make application and database servers fault tolerant.
What rack-mountable device can provide line filtering and power monitoring features?
A Power Distribution Unit (PDU).
