Question 1

An IT professional is tasked with optimizing network performance by reducing unnecessary broadcast traffic.

Which approach will help achieve this goal without disrupting the current network topology?

Set up a redundant switch to handle excess broadcast traffic as needed.
Implement VLANs to logically separate devices into smaller broadcast domains.
Configure static entries in the MAC address table for all devices.

Question 2

In a data center, a network administrator is configuring a multi-chassis link aggregation using the DRCP protocol. They want to ensure that any down events are detected as quickly as possible.

Which configuration should they choose to meet this need?

Use an external monitoring tool to detect down events.
Enable the short DRCP timer, where the peer sends DUs every second.
Enable the long DRCP timer, where the peer sends DUs every 30 seconds.

Select an answer above, then submit your vote. Reading or practicing does not cast a vote.

Question 3

A network device is experiencing high traffic volumes. The network engineer needs to ensure that critical application traffic is not dropped despite the congestion. They decide to implement a QoS strategy.

Which tool should they configure to manage and prioritize this traffic effectively?

Marking to tag packets with priority values in headers based on type
Scheduling to decide the order of packet transmission from different queues
Rate limiting to prevent overwhelming the system with excess packets

Select an answer above, then submit your vote. Reading or practicing does not cast a vote.

Question 4

In a scenario where a network experiences sporadic congestion due to temporary high traffic loads, what is the primary advantage of implementing Quality of Service (QoS) over simply increasing bandwidth?

QoS completely replaces the need for TCP acknowledgment mechanisms.
QoS provides prioritized traffic management without significant cost increases.
QoS increases the overall speed of the network for all types of traffic.

Select an answer above, then submit your vote. Reading or practicing does not cast a vote.

Question 5

In a data center, a network engineer observes that when the DR interface of Agg-2 fails, traffic to Acc-1 is still being successfully forwarded.

How does the DR system ensure continuous traffic flow in this scenario?

Agg-1 directly reroutes the traffic to Acc-1 without involving Agg-2.
The DR system temporarily stores traffic until the DR interface is restored.
Agg-2 sends traffic over the IPL to Agg-1, which then forwards it to Acc-1.

Select an answer above, then submit your vote. Reading or practicing does not cast a vote.

Question 6

A tech company is optimizing their network to support high-quality video conferencing. They need to prioritize this traffic using QoS marks. The video packets are marked with AF31 and they need to ensure these packets are prioritized over standard traffic.

How should the Comware switch be configured?

Assign AF31 traffic to a higher priority queue than CS0
Assign AF31 traffic to a lower priority queue than CS0
Assign AF31 traffic to the same queue as CS0

Select an answer above, then submit your vote. Reading or practicing does not cast a vote.
