Question 1 of 15

In a network, which factor determines the selection of the best path for data packet traversal?

  • Diverting traffic

  • Bandwidth

  • Metric

Question 2 of 15

A company has recently implemented a new Wi-Fi network in their office. Employees are experiencing intermittent connectivity and slow network performance. Investigation shows that the Wi-Fi access points are broadcasting on overlapping channels. Which of the following would be the best course of action to resolve this issue?

  • Increase the signal strength of all access points to maximize coverage

  • Change all Wi-Fi passwords to restrict network access

  • Change the channels on the access points to non-overlapping settings such as channels 1, 6, and 11

  • Reposition all access points to different locations within the office

Question 3 of 15

When initially addressing a network outage, what should be done FIRST according to the standard troubleshooting methodology?

  • Duplicate the problem

  • Gather information

  • Question users

  • Establish a theory of probable cause

Question 4 of 15

Which of the following best describes the Ethernet frame size specified under the 802.3 standards?

  • 1500 to 1522 bytes

  • 100 to 1500 bytes

  • 128 to 1024 bytes

  • 64 to 1518 bytes

Question 5 of 15

MTTR refers exclusively to the time taken to detect a network issue.

  • False

  • True

Question 6 of 15

In a large data center, a network engineer is optimizing the flow of traffic between servers within the same layer to reduce latency and improve performance. This type of traffic flow is known as:

  • East-west

  • North-south

  • Diagonal

  • Vertical

Question 7 of 15

Which technology offers the best solution for linking multiple data centers to enable them to operate cohesively, with support for high-volume traffic and extensive scalability?

  • Generic Routing Encapsulation (GRE)

  • Internet Protocol Security (IPSec)

  • Layer 2 Tunneling Protocol Version 3 (L2TPv3)

  • VXLAN

Question 8 of 15

What environment is specifically suited for the use of plenum-rated cables?

  • Underground network tunnels without climate control

  • Inside standard office wall partitions

  • In plenum spaces, where air circulation for HVAC systems occurs

  • In outdoor environments exposed to weather

Question 9 of 15

A network administrator suspects that a network issue is related to an incorrect configuration on a newly deployed router. After interviewing users and identifying the symptoms, the administrator has established a theory. What is the BEST next step to confirm if their theory about the router's configuration is the cause of the issue?

  • Analyze the router's log files for error messages.

  • Implement the suspected configuration changes on a test router or in a controlled segment of the network.

  • Reboot the router to see if the problem persists.

  • Replace the router with a different model to determine if the issue resolves.

Question 10 of 15

A multinational company must adhere to strict privacy laws concerning personal information of individuals from a European region. Which of the following is the BEST practice for managing data locality to ensure compliance?

  • Storing backups of the personal information in international locations while processing takes place within the region

  • Utilizing local data centers within the same region for storing and processing all related personal information

  • Employing robust encryption for the personal information while it is transmitted to external regions

Question 11 of 15

IP address management tools are only used for documenting static IP addresses assigned within a network.

  • False

  • True

Question 12 of 15

An enterprise has recently expanded its operations, and employees are experiencing slow network speeds. The IT manager suspects the issue might be due to the current throughput not meeting the increased demand created by additional users and upgraded applications. What would be an effective method to confirm if throughput capacity is indeed the root cause of the slow network speeds?

  • Replace all existing Ethernet cables with higher category ones.

  • Increase the number of access points in the network.

  • Upgrade the firmware on all network routers.

  • Inspect all networking devices for hardware faults.

  • Perform network bandwidth analysis.

Question 13 of 15

What is the primary purpose of Classless Inter-domain Routing (CIDR) in network configuration?

  • To extend the usable life of IPv4 by adding additional bits to the IP address structure

  • To restrict network traffic by implementing stricter IP address regulations

  • To allow variable length subnet masks, improving IP address allocation and route summarization

  • To enhance the security features embedded within IP addresses through encryption techniques

Question 14 of 15

An organization uses a network configured with routers handling multiple subnets. While establishing a route for new data packets, which type of address does the router primarily use to determine the next hop?

  • MAC address

  • Service number

  • IP address

  • Port number

Question 15 of 15

A large organization with various departments requires a systematic approach to handle the complexity of their network address spaces. Which tool is most appropriate for maintaining an organized system for documenting, tracking, and allocating network addresses?

  • Configuration Management Database (CMDB)

  • Domain Name System (DNS) server

  • Dynamic Host Configuration Protocol (DHCP) server

  • IP Address Management (IPAM) software
