FC0-U61 Timed Practice Test 5 — 10 Questions

Question 1

Which device is used to connect multiple devices within the same network segment and forward data based on MAC addresses?

Accepted Answer

Switch. A switch operates at Layer 2 (Data Link Layer) of the OSI model and uses MAC addresses to make forwarding decisions. It maintains a MAC address table (CAM table) to learn which port each device is connected to, allowing it to forward frames only to the intended destination port, reducing collisions and improving network efficiency.

Answer

Hub

Answer

Modem

Answer

Router

Question 2

A technician needs to set up a small office network with 15 computers. The computers should be able to communicate with each other and share a single internet connection. Which device is required to enable internet sharing?

Accepted Answer

Router. A router is required to enable internet sharing because it performs Network Address Translation (NAT), which allows multiple devices on a local network to share a single public IP address provided by the ISP. The router also routes traffic between the local subnet and the internet, making it the essential device for both inter-device communication and internet access.

Answer

Modem

Answer

Hub

Answer

Switch

Question 3

A user reports that they cannot print to a network printer. Other users can print to the same printer. Which of the following should the technician check FIRST?

Accepted Answer

The printer driver on the user's computer. Since other users can print to the same network printer, the printer itself, its network connectivity, and its IP address are all functioning correctly. The issue is isolated to the single user's computer, making the printer driver on that machine the most likely cause. A corrupted, missing, or incorrect driver would prevent that specific user from sending print jobs while others remain unaffected.

Answer

The printer's IP address

Answer

The network switch port

Answer

The printer's power cable

Question 4

Which TWO of the following are benefits of virtualization in a data center?

Accepted Answer

Improved disaster recovery capabilities. Virtualization enables rapid restoration of virtual machines (VMs) from snapshots or backups, often within minutes, regardless of underlying hardware failures. This decoupling of the OS from physical hardware allows VMs to be migrated or recovered on different hosts, significantly improving recovery time objectives (RTOs) and recovery point objectives (RPOs) compared to physical server recovery.

Answer

Increased hardware reliability

Answer

Enhanced physical security

Answer

Simplified network configuration

Question 5

A company's server room is experiencing intermittent overheating. The administrator notices that the perforated floor tiles are blocked by equipment. What is the most likely consequence of this obstruction?

Accepted Answer

Reduced cooling efficiency and hot spots. Blocking perforated floor tiles restricts the flow of cold air from the raised-floor plenum into the server room. This reduces the overall cooling efficiency of the HVAC system and creates localized hot spots around the obstructed tiles, which can lead to equipment overheating and failure.

Answer

Increased electrical load on the UPS

Answer

Increased humidity levels

Answer

Reduced battery backup time

Question 6

A technician is setting up a new computer on a network. The computer receives an IP address of 169.254.1.5. Which of the following is the most likely issue?

Accepted Answer

The DHCP server is unavailable. The IP address 169.254.1.5 falls within the Automatic Private IP Addressing (APIPA) range (169.254.0.0/16), which Windows automatically assigns when a DHCP client fails to receive an IP lease from a DHCP server. This indicates that the DHCP server is either unreachable or not responding, making D the correct answer.

Answer

The network cable is faulty

Answer

The DNS server is unreachable

Answer

The gateway is misconfigured

Question 7

Refer to the exhibit. This JSON policy is associated with an IAM user. Which of the following actions is the user permitted to perform?

Accepted Answer

Download files from example-bucket. The JSON policy grants the s3:GetObject action on the arn:aws:s3:::example-bucket/* resource, which allows the user to retrieve (download) objects from the specified S3 bucket. The Effect is set to 'Allow', so the policy explicitly permits this action. No other actions are listed in the Statement, so only downloads are permitted.

Answer

Upload files to example-bucket

Answer

Delete files from example-bucket

Answer

List the contents of example-bucket

Question 8

A small business has 20 employees using a mix of wired and wireless devices. The network uses a single router with built-in 4-port switch and Wi-Fi. Recently, employees have reported intermittent connectivity drops, especially during peak hours. The technician notices that the router's CPU usage is consistently at 90% or higher. The business cannot afford to replace the router immediately. Which of the following actions would BEST improve the situation without purchasing new hardware?

Accepted Answer

Configure VLANs to separate wired and wireless traffic. Configuring VLANs separates wired and wireless traffic into distinct broadcast domains, reducing the amount of broadcast traffic and collisions that the router's CPU must process. This lowers CPU overhead, which directly addresses the 90% CPU usage causing intermittent drops, without requiring new hardware.

Answer

Disable Quality of Service (QoS) settings

Answer

Disable the Wi-Fi network and require all devices to connect via Ethernet

Answer

Assign static IP addresses to all devices

Question 9

Match each network protocol to its well-known port number.

Question 10

Match each network type to its description.
