Question 20: A US telecom CFO presents a project with an NPV (Net Present Value) of $0. What does this indicate about the investment?

The project will generate no revenue
The project has no risk
The project's discounted cash inflows exactly equal its initial investment cost, earning exactly the required rate of return (Correct answer)
The project should be rejected outright

Correct answer: The project's discounted cash inflows exactly equal its initial investment cost, earning exactly the required rate of return

An NPV of $0 means the investment earns exactly the discount rate (hurdle rate) used in the calculation — it neither creates nor destroys value beyond the required return.

Question 21: A CTE is assessing disaster recovery for a critical network hub. The recovery point objective (RPO) is set to zero. What does this require?

Daily tape backups shipped offsite
Synchronous real-time replication with no data loss tolerance (Correct answer)
Asynchronous replication with 15-minute lag
Weekly database exports to cloud storage

Correct answer: Synchronous real-time replication with no data loss tolerance

An RPO of zero means absolutely no data can be lost, requiring synchronous real-time replication between primary and secondary sites.

Question 22: In telecom cost management, what does 'total cost of ownership' (TCO) analysis include beyond the initial purchase price of network equipment?

Only ongoing software licensing fees
Only labor costs for installation

State Public Utility Commissions have authority to arbitrate interconnection disputes between CLECs and ILECs under Section 252 of the Telecommunications Act.

Question 26: When a US carrier reports 'free cash flow,' what does this metric represent and why do telecom investors prioritize it?

Net income before depreciation
Operating cash flow minus capital expenditures, representing cash available for dividends, debt repayment, and M&A after sustaining the network (Correct answer)
Total revenue minus total debt
Revenue minus marketing expenses

Correct answer: Operating cash flow minus capital expenditures, representing cash available for dividends, debt repayment, and M&A after sustaining the network

Free cash flow (FCF = operating cash flow minus CapEx) shows actual cash generated after network investment, making it the most important metric for telecom investors assessing dividend sustainability and financial health.

Question 27: In telecom cloud environments, what is the primary purpose of a 'sidecar' container pattern?

To act as a load balancer between microservices
To augment a main container with auxiliary functions like logging, monitoring, or proxying without modifying it (Correct answer)
To provide a separate container for storing persistent data
To run backup copies of the main application container

Correct answer: To augment a main container with auxiliary functions like logging, monitoring, or proxying without modifying it

The sidecar pattern deploys a helper container alongside the main container in the same pod, injecting cross-cutting concerns without changing the main application.

Question 28: What is the critical path in CTE project scheduling?

The most expensive phase
Tasks that can be skipped
The longest sequence of dependent tasks determining minimum duration (Correct answer)
The shortest route to complete cheaply

Correct answer: The longest sequence of dependent tasks determining minimum duration

The critical path identifies the longest chain of dependent tasks; delays on these directly delay project completion.

Question 29: What does data integrity mean in CTE practice?
