Question 1

In a telecom data center, what does the term PUE (Power Usage Effectiveness) measure?

Accepted Answer

The ratio of total facility power to IT equipment power, where 1.0 is perfect efficiency

Answer

PUE = total facility energy divided by IT equipment energy; a PUE of 1.0 means all power goes to IT with zero overhead from cooling and infrastructure.

Question 2

Which routing protocol is most commonly used for inter-AS (Autonomous System) routing on the internet backbone?

Accepted Answer

BGP-4

Answer

BGP-4 (Border Gateway Protocol version 4) is the de facto standard exterior gateway protocol used to exchange routing information between autonomous systems on the internet.

Question 3

A carrier deploys Carrier Ethernet with E-Line service. What type of logical connection does E-Line provide?

Accepted Answer

Point-to-point Ethernet Virtual Connection between two sites

Answer

E-Line (defined by MEF) provides a point-to-point Ethernet Virtual Connection (EVC) between exactly two User-Network Interfaces (UNIs).

Question 4

What is the function of the Mobility Management Entity (MME) in an LTE Evolved Packet Core (EPC)?

Accepted Answer

It manages UE attach/detach, authentication, and mobility signaling in the control plane

Answer

The MME handles all control-plane signaling for LTE, including subscriber authentication, bearer establishment, and tracking area management during UE mobility.

Question 5

In a fiber-to-the-home (FTTH) GPON deployment, what is the maximum logical split ratio per OLT port?

Accepted Answer

1:64

Answer

GPON (ITU-T G.984) supports a maximum logical split ratio of 1:64, meaning one OLT port can serve up to 64 ONUs/ONTs over a passive optical distribution network.
