TMP Network Design & Optimization 5

Question 1

Which protocol is commonly used to collect traffic flow statistics from routers to support network capacity planning?

Accepted Answer

NetFlow / IPFIX

Answer

NetFlow and its standardized successor IPFIX export detailed flow records (source, destination, protocol, volume) from routers for traffic analysis.

Question 2

A telecom manager is designing a disaster recovery network. Which Recovery Time Objective (RTO) value indicates the STRICTEST recovery requirement?

Accepted Answer

RTO of 15 minutes

Answer

A shorter RTO is stricter because it requires the network to be restored faster; 15 minutes demands far more robust failover infrastructure than 24 hours.

Question 3

In a dual-stack network migration to IPv6, what problem does a 6to4 tunnel solve?

Accepted Answer

Carries IPv6 traffic over existing IPv4 infrastructure without requiring native IPv6 links

Answer

6to4 encapsulates IPv6 packets within IPv4 headers, enabling IPv6 communication across IPv4-only network segments during migration.

Question 4

What is the role of a network management system (NMS) in ongoing network optimization?

Accepted Answer

To continuously monitor performance metrics and generate alerts when thresholds are exceeded

Answer

An NMS collects SNMP and flow data, tracks KPIs, and alerts operations teams to performance degradations before they become outages.

Question 5

A campus network is experiencing broadcast storms. Which mechanism should be implemented to protect the network?

Accepted Answer

Enable storm control with broadcast rate limiting on access ports

Answer

Storm control monitors broadcast traffic rates on interfaces and blocks traffic that exceeds the defined threshold, preventing broadcast storms from saturating the network.
