FC0-U61 Practice Test 22 — 15 Questions

Question 1

Refer to the exhibit. A user can successfully ping the local default gateway but cannot ping an external IP address. What is the most likely cause?

Accepted Answer

The internet connection is down. Since the user can successfully ping the local default gateway, the Layer 2 and Layer 3 connectivity within the local subnet is intact, ruling out issues with the NIC, subnet mask, or local routing. The failure to ping an external IP address indicates that traffic is not being forwarded beyond the local network, which most commonly occurs when the internet connection (WAN link) is down or the ISP's upstream router is unreachable.

Answer

The network interface card is faulty

Answer

The DNS server is not responding

Answer

The subnet mask is misconfigured

Question 2

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 3

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

Question 4

Based on the exhibit, which type of attack is most likely occurring?

Accepted Answer

Brute force attack. The exhibit shows repeated login attempts with different passwords (e.g., 'password1', 'password2', 'password3') against a single user account. This pattern of systematically trying many passwords to guess credentials is the hallmark of a brute force attack. Unlike a denial-of-service or phishing attack, the goal here is to gain unauthorized access by exhausting possible password combinations.

Answer

Denial-of-service attack

Answer

Phishing attack

Answer

Man-in-the-middle attack

Question 5

A database administrator is designing a normalized database. Which TWO are benefits of normalization?

Accepted Answer

Reduces data redundancy. Normalization reduces data redundancy (Option B) and eliminates update anomalies (Option D). Option A is false (increases complexity), C is false (more joins may reduce performance), E is false (requires more tables).

Answer

Improves query performance

Answer

Increases data redundancy

Answer

Requires fewer tables

Question 6

Refer to the exhibit. A computer displays this error during startup. Which component is most likely the cause of the issue?

Accepted Answer

Hard drive. Option C (Hard drive) is correct because the error explicitly states that the hard disk is not found, indicating a problem with the storage device or its connection. Option A (RAM) would typically cause beep codes or a blank screen, not a boot device error. Option B (CPU) failure usually results in no power or beeps. Option D (Power supply) issues often lead to no power or intermittent shutdowns, not a specific hard disk error.

Answer

RAM

Answer

Power supply

Answer

CPU

Question 7

A small business with 50 employees currently hosts its email and file-sharing server on-premises on a single physical server. The server is experiencing frequent hardware failures, causing downtime and data loss. The owner wants a solution that improves reliability, scalability, and reduces the need for in-house maintenance. The company has a limited IT budget and wants to avoid large upfront hardware costs. The owner is concerned about data security and compliance but is open to cloud solutions. As an IT consultant, which of the following would be the best recommendation?

Accepted Answer

Migrate to a public cloud IaaS solution. Option A is correct because migrating to a public cloud IaaS solution provides scalability, high availability, and reduces maintenance overhead without large upfront costs. Option B is incorrect because purchasing a more powerful server does not eliminate the hardware failure risk; it only delays the problem. Option C is incorrect because backup alone does not prevent downtime; it only enables recovery after an outage. Option D is incorrect because a peer-to-peer network lacks centralized management and reliability, making it unsuitable for a 50-user business.

Answer

Implement a regular backup strategy

Answer

Purchase a more powerful on-premises server

Answer

Move to a peer-to-peer network

Question 8

A small business wants to store customer contact information and order history. The data is structured and relationships between customers and orders must be enforced. Which type of database is most appropriate?

Accepted Answer

Relational database. A relational database (Option A) is best for structured data with relationships. NoSQL (B) is for unstructured data, flat file (C) lacks relationships, and hierarchical (D) is less flexible.

Answer

Flat-file database

Answer

NoSQL database

Answer

Hierarchical database

Question 9

Refer to the exhibit. A database contains tables Customers and Orders. Based on the query, what is the purpose of the INNER JOIN clause?

Accepted Answer

To return only customers who have at least one order in New York. INNER JOIN retrieves records where the CustomerID matches in both tables, ensuring only customers with orders from New York are listed (Option C). Option A is wrong because LEFT JOIN would include all customers. Option B is wrong because it returns matching rows, not all rows. Option D describes a CROSS JOIN.

Answer

To create a Cartesian product of customers and orders

Answer

To combine all rows from both tables regardless of match

Answer

To include all customers even if they have no orders

Question 10

A user is trying to install a new application but receives an error that the system does not meet the minimum requirements. Which TWO hardware components should the user check first to ensure compatibility?

Accepted Answer

Available storage space. Option A (Available storage space) is correct because applications require a minimum amount of free disk space to install and run. Option C (Amount of RAM) is correct because insufficient memory can prevent installation or cause poor performance. Option B (Monitor refresh rate) is irrelevant to application installation. Option D (CPU clock speed) is important but not as commonly checked as RAM and storage for typical applications; however, the question asks for TWO components, and storage and RAM are the most fundamental. Option E (Number of USB ports) is unrelated.

Answer

CPU clock speed

Answer

Number of USB ports

Answer

Monitor refresh rate

Question 11

Which TWO of the following are best practices for creating and managing passwords?

Accepted Answer

Enable multi-factor authentication where available. Options B and D are correct. Using a unique password for each account prevents a single breach from compromising multiple accounts. Enabling multi-factor authentication adds an extra layer of security beyond the password. Option A is wrong because writing down passwords increases risk of theft. Option C wrong because password history enforcement (requiring new passwords to be unique) is good, but reusing a password after a few cycles is still reuse; the statement as phrased is not a best practice—actually, option C says 'Reuse passwords every 90 days' which is poor. Option E wrong because sharing passwords in a team undermines accountability and security.

Answer

Share passwords with colleagues in the same department to improve collaboration

Answer

Reuse passwords every 90 days

Answer

Write down passwords on a sticky note and keep it near the computer

Question 12

Which TWO of the following are advantages of using a virtual private network (VPN) for remote employees?

Accepted Answer

Provides encrypted communication. Options B and C are correct. VPNs provide encrypted communication (B) and allow access to internal resources (C). Option A is incorrect because VPNs typically reduce bandwidth due to encryption overhead. Option D is incorrect because VPNs do not directly reduce hardware costs. Option E is incorrect because a VPN does not eliminate the need for antivirus software.

Answer

Eliminates need for antivirus software

Answer

Reduces hardware costs

Answer

Increases network bandwidth

Question 13

What is the most likely reason PC1 cannot ping PC2?

Accepted Answer

A firewall on PC2 is blocking ICMP echo requests. Option C is correct because a firewall on PC2 can be configured to block ICMP echo requests (ping) while allowing other traffic. Option A is incorrect because if PC2's NIC were disabled, PC1 would not be able to communicate with PC2 at all, and the ping would fail, but it's not the most likely scenario given that PC1 can ping PC3 (indicating the switch and network are functioning). Option B is incorrect because a default gateway is only required for off-subnet communication; PC1 and PC2 are on the same subnet. Option D is incorrect because if the switch port for PC2 were faulty, PC2 would have no network connectivity, and PC1 would fail to reach it for any service, not just ping.

Answer

The default gateway is incorrect on PC1

Answer

PC2's network interface is disabled

Answer

The switch port for PC2 is faulty

Question 14

A user reports that their computer is running slowly and the network activity light is constantly on. The technician runs the command shown in the exhibit. Based on the output, what is the most likely cause?

Accepted Answer

The computer is infected with malware communicating with a command-and-control server. The exhibit shows multiple established connections from the local computer to the same remote IP on port 443 (HTTPS). This pattern suggests a botnet or malware establishing multiple command-and-control channels. Option B is correct because it indicates a malware infection. Option A is wrong because a DoS attack would typically show many connections from different sources. Option C wrong because a firewall misconfiguration would block or allow traffic, not create multiple connections. Option D wrong because excessive web browsing would show connections to various IPs, not just one.

Answer

The computer is experiencing a denial-of-service (DoS) attack

Answer

The user is running excessive web browsing sessions

Answer

The firewall is misconfigured and blocking legitimate traffic

Question 15

Which TWO of the following are characteristics of the Agile software development methodology?

Accepted Answer

Customer collaboration. Agile emphasizes iterative development and customer collaboration, not upfront planning or heavy documentation.

Answer

Emphasis on detailed upfront planning

Answer

Heavy documentation

Answer

Rigid change control
