A Company Is Planning to Connect Its 30 Sites with a VPLS

question 50

Multiple Choice

A company is planning to connect its 30 sites with a VPLS WAN backbone. A router at each site should establish neighborships with all other routers using the OSPF routing protocol. Which three points must be considered regarding DR and BDR when different router platforms are used? (Choose three.)

• A) It is a best practice that the routers with the most powerful hardware should take the role of the DR and BDR.
• B) If the IP OSPF priority is the same for all routers, the highest loopback IP address and router ID will decide which routers will take the DR and BDR role during the selection process.
• C) To select the DR and BDR, the IP OSPF priority must be set to a higher value than the default value at the DR and BDR during the selection process.
• D) To select the DR and BDR, the IP OSPF priority must be set to a lower value than the default value at the DR and BDR during the selection process.
• E) The role for the DR and BDR will be selected when a new OSPF router comes up.
• F) To force two routers to become a DR and a BDR, the IP OSPF priority can be set to zero at all other OSPF routers.

Intervening Variables

Factors within a study that mediate the relationship between the independent and dependent variables, potentially affecting the outcome.

Negative Reinforcement

a behavior modification technique where the removal of an undesirable or unpleasant outcome after the display of a desired behavior increases the likelihood of the behavior being repeated.

Spontaneous Recovery

The reappearance of a previously extinguished conditioned response after a period without exposure to the conditioned stimulus.

Stimulus Generalization

The process by which a conditioned response becomes associated with stimuli that are similar but not identical to the original conditioned stimulus.
