FC0-U61 Infrastructure Practice Test 5 — 15 Questions

Question 1

An administrator is configuring access to an S3 bucket. The policy is applied to an IAM user. Which of the following actions will the user be allowed to perform?

Accepted Answer

Read and write objects in my-company-bucket. The IAM policy applied to the user explicitly grants 's3:GetObject' and 's3:PutObject' actions on the 'my-company-bucket' resource, which correspond to reading and writing objects. This is the only action set permitted by the policy, so the user can read and write objects in the bucket.

Answer

List all objects in my-company-bucket

Answer

Delete objects from my-company-bucket

Answer

Change the bucket policy of my-company-bucket

Question 2

A user is trying to print but receives the error shown in the exhibit. Which of the following is the MOST likely cause?

Accepted Answer

Printer is powered off or disconnected from the network. The error shown in the exhibit (e.g., 'Printer not responding' or 'Offline') typically indicates the printer is powered off or disconnected from the network. When a printer is unreachable on the TCP/IP network, the print spooler cannot establish a connection to the printer's IP address or hostname, resulting in this error. This is the most common cause before investigating software or consumable issues.

Answer

Corrupt printer driver

Answer

Paper jam in the printer

Answer

Low toner level

Question 3

A small office has five desktop computers that need to be connected to share files and a printer. Which network device should be used to create a local area network?

Accepted Answer

Switch. A switch is the correct device because it operates at Layer 2 of the OSI model, using MAC addresses to forward frames only to the specific port where the destination device is connected. This creates a dedicated, collision-free path between any two communicating devices, which is essential for a small office LAN where five computers need to share files and a printer efficiently.

Answer

Hub

Answer

Modem

Answer

Router

Question 4

A user wants to connect a laptop to a corporate wireless network. What internal component must be present in the laptop?

Accepted Answer

Wireless NIC. A Wireless NIC (Network Interface Card) is the internal component required for a laptop to connect to a corporate wireless network. It contains a radio transceiver that communicates with wireless access points using IEEE 802.11 standards (e.g., 802.11ax), handling frame encapsulation, authentication, and encryption such as WPA3. Without a wireless NIC, the laptop has no physical layer capability to transmit or receive Wi-Fi signals.

Answer

Cellular modem

Answer

Infrared port

Answer

Bluetooth adapter

Question 5

A technician needs to verify that a twisted-pair Ethernet cable is wired correctly and has no breaks. Which tool should be used?

Accepted Answer

Cable tester. A cable tester sends signals through each conductor in the twisted-pair cable and checks for continuity, correct pin-to-pin wiring (e.g., T568A or T568B), and shorts or opens. This makes it the correct tool to verify proper wiring and detect breaks in an Ethernet cable.

Answer

Multimeter

Answer

Loopback plug

Answer

Toner probe

Question 6

A company has two office buildings 1.5 km apart and needs to connect their networks with a high-speed, reliable link. Which cabling type is most appropriate?

Accepted Answer

Fiber optic. Fiber optic cabling is the most appropriate choice for connecting two office buildings 1.5 km apart because it supports high-speed data transmission over long distances (up to several kilometers) with minimal signal loss and immunity to electromagnetic interference (EMI). Unlike copper-based cables, fiber optic uses light pulses to transmit data, making it ideal for reliable, high-bandwidth links between separate buildings.

Answer

Cat6a

Answer

Coaxial

Answer

Cat5e

Question 7

A user can access the internet and other computers on the network but cannot print to a network printer that is on the same subnet. The printer's IP is 192.168.1.100. What is the most likely cause?

Accepted Answer

The printer is powered off. Option D is correct because if the printer is powered off, it cannot respond to print jobs, yet the user can still access the internet and other computers on the network since those services are independent of the printer. The printer's IP address (192.168.1.100) being on the same subnet means that connectivity to it relies solely on the printer being powered on and operational at Layer 2 (Ethernet) and Layer 3 (IP). A powered-off printer will not respond to ARP requests or TCP connections, causing print jobs to fail while other network functions remain unaffected.

Answer

The router is not forwarding print jobs

Answer

The user's computer has a wrong subnet mask

Answer

The printer's DNS is misconfigured

Question 8

A network administrator wants to automatically assign IP addresses to all devices on the network. Which service should be configured on the server?

Accepted Answer

DHCP. Dynamic Host Configuration Protocol (DHCP) is the correct service because it automatically assigns IP addresses, subnet masks, default gateways, and other network configuration parameters to devices on a network. This eliminates the need for manual static IP configuration and ensures each device receives a unique IP address from a defined pool, preventing address conflicts.

Answer

DNS

Answer

HTTP

Answer

NAT

Question 9

After a network upgrade, a user reports that their computer intermittently loses network connectivity. The link light remains on, but the activity light flashes rapidly and irregularly. What is the most likely cause?

Accepted Answer

Bad Ethernet cable. The intermittent connectivity with the link light on but the activity light flashing rapidly and irregularly is a classic symptom of a faulty or marginal Ethernet cable. A bad cable can cause excessive collisions or frame errors, leading to retransmissions that manifest as rapid, irregular activity light flashing while the physical link (link light) remains established. This is distinct from issues like IP conflicts or driver corruption, which typically do not produce this specific link/activity light behavior.

Answer

IP address conflict

Answer

Driver corruption

Answer

Faulty NIC

Question 10

A small business purchases a cable modem from the ISP. They need to obtain a public IP address to access the internet. Which method does the cable modem typically use?

Accepted Answer

DHCP. Cable modems typically use DHCP to obtain a public IP address from the ISP. When the modem powers on, it sends a DHCPDISCOVER broadcast, and the ISP's DHCP server responds with an IP address, subnet mask, default gateway, and DNS server information. This is the standard method for dynamically assigning public IP addresses to customer premises equipment (CPE) in cable networks.

Answer

NAT

Answer

Static assignment

Answer

APIPA

Question 11

A network administrator wants to restrict access to the wireless network to only approved devices. Which security feature should be enabled on the access point?

Accepted Answer

MAC filtering. MAC filtering allows the access point to permit or deny network access based on the device's MAC address, which is a unique hardware identifier. By creating an allowlist of approved MAC addresses, the administrator can restrict the wireless network to only those devices. This directly addresses the requirement to limit access to approved devices.

Answer

Firewall rules

Answer

Disable SSID broadcast

Answer

WPA2 encryption

Question 12

Which TWO of the following are common Ethernet cable categories used in local area networks?

Accepted Answer

Cat5e. Cat5e and Cat6 are twisted-pair cables commonly used for Ethernet. Coaxial is used for cable TV, HDMI for audio/video, USB for peripherals.

Answer

USB

Answer

Coaxial

Answer

HDMI

Question 13

Which THREE of the following are primary functions of a network router?

Accepted Answer

Forwarding packets based on IP addresses. B is correct because a router's primary function is to forward packets between different networks by examining the destination IP address in the packet header and consulting its routing table to determine the best path. This Layer 3 (Network Layer) operation is fundamental to routing, distinguishing it from switches that operate at Layer 2.

Answer

Providing wireless access to clients

Answer

Connecting devices within the same local network

Question 14

Which TWO of the following are effective methods to help secure a wireless network from unauthorized access?

Accepted Answer

Enabling WPA2 encryption. WPA2 encryption and MAC filtering are effective. WEP is weak and easily broken, broadcasting SSID makes the network visible, and disabling the firewall reduces security.

Answer

Enabling WEP encryption

Answer

Disabling the firewall

Answer

Broadcasting the SSID

Question 15

Refer to the exhibit. A user cannot access the internet. What is the most likely issue based on the configuration shown?

Accepted Answer

The default gateway is missing. The exhibit shows an IP address of 192.168.1.10 with a subnet mask of 255.255.255.0, but no default gateway is configured. Without a default gateway, the device can communicate within its local subnet (192.168.1.0/24) but cannot route traffic to any external network, including the internet. The default gateway is the router's IP address that provides the next-hop path for all off-subnet traffic.

Answer

The DNS server is not configured

Answer

The IP address is invalid

Answer

The subnet mask is incorrect
