CompTIA Network+ Certification Exam Sample Questions (Q249-Q254):

NEW QUESTION # 249
SIMULATION
You have been tasked with setting up a wireless network in an office. The network will consist of
3 Access Points and a single switch. The network must meet the following parameters:
- The SSIDs need to be configured as CorpNet with a key of S3cr3t!
- The wireless signals should not interfere with each other
- The subnet the Access Points and switch are on should only support 30 devices maximum
- The Access Points should be configured to only support TKIP clients at a maximum speed INSTRUCTONS Click on the wireless devices and review their information and adjust the settings of the access points to meet the given requirements.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.



Answer:

Explanation:
On the first exhibit, the layout should be as follows





Exhibit 2 as follows
Access Point Name AP2



Exhibit 3 as follows
Access Point Name AP3



NEW QUESTION # 250
A user is unable to navigate to a website because the provided URL is not resolving to the correct IP address. Other users are able to navigate to the intended website without issue. Which of the following is most likely causing this issue?

  • A. Nameserver record
  • B. Hosts file
  • C. Self-signed certificate
  • D. IP helper

Answer: B

Explanation:
Role of the Hosts File:
The hosts file is a local file on a computer that maps hostnames to IP addresses. It can be used to override DNS resolution by providing a static mapping of a hostname to an IP address.
Common Issues with the Hosts File:
If an incorrect IP address is mapped to a hostname in the hosts file, it can cause the computer to resolve the hostname to the wrong IP address. This can lead to navigation issues for specific websites while other users, relying on DNS, do not face the same problem.


NEW QUESTION # 251
A medical clinic recently configured a guest wireless network on the existing router. Since then, guests have been changing the music on the speaker system. Which of the following actions should the clinic take to prevent unauthorized access? (Select two).

  • A. Configure GRE on the wireless router.
  • B. Isolate smart devices to their own network segment.
  • C. Configure IPS to prevent guests from making changes.
  • D. Set up a syslog server to log who is making changes.
  • E. Change the default credentials.
  • F. Install a new AP on the network.

Answer: B,E

Explanation:
*A. Isolate smart devices to their own network segment: Network segmentation using VLANs or separate SSIDs ensures that smart devices (like speakers) are not on the same network as guests, preventing unauthorized control.
*E. Change the default credentials: Many IoT devices (e.g., smart speakers) come with default usernames and passwords. If these are not changed, unauthorized users can easily take control.
*Why not the other options?
*B. Configure IPS: IPS (Intrusion Prevention System) detects threats but cannot block specific guest actions on an IoT device.
*C. Install a new AP: A new access point does not solve the unauthorized control issue.
*D. Set up a syslog server: Helps with logging, but does not prevent unauthorized access.
*F. Configure GRE: Generic Routing Encapsulation (GRE) is used for VPN tunneling, which is irrelevant in this case.


NEW QUESTION # 252
A network administrator needs to assign IP addresses to a newly installed network. They choose
192.168.1.0/24 as their network address and need to create three subnets with 30 hosts on each subnet. Which of the following is a valid subnet mask that will meet the requirements?

  • A. 255.255.255.240
  • B. 255.255.255.192
  • C. 255.255.255.128
  • D. 255.255.255.224

Answer: B

Explanation:
To create three subnets with at least 30 hosts each:
Subnet Calculation: Each subnet must support 32 addresses (30 usable + 2 reserved for network and broadcast).
Bits for Subnets: Subnet mask 255.255.255.192 (/26) provides 64 addresses per subnet (4 subnets total).
Valid Subnets: Each subnet provides sufficient IPs to meet the requirement.


NEW QUESTION # 253
Which of the following disaster recovery concepts is calculated by dividing the total hours of operation by the total number of units?

  • A. MTBF
  • B. MTTR
  • C. RTO
  • D. RPO

Answer: A

Explanation:
Introduction to Disaster Recovery Concepts:
Disaster recovery involves strategies and measures to ensure business continuity and data recovery in the event of a disaster.
Mean Time Between Failures (MTBF):
MTBF is a reliability metric used to predict the time between failures of a system during operation. It is calculated by dividing the total operational time by the number of failures.
Formula: MTBF=Total Operational TimeNumber of Failurestext{MTBF} = frac{text{Total Operational Time}}{text{Number of Failures}}MTBF=Number of FailuresTotal Operational Time This metric helps in understanding the reliability and expected lifespan of systems and components.
Example Calculation:
If a server operates for 1000 hours and experiences 2 failures, the MTBF is:
MTBF=1000 hours2=500 hourstext{MTBF} = frac{1000 text{ hours}}{2} = 500 text{ hours} MTBF=21000 hours=500 hours Explanation of the Options:
A: MTTR (Mean Time to Repair): The average time required to repair a system after a failure.
B: MTBF (Mean Time Between Failures): The correct answer, representing the average time between failures.
C: RPO (Recovery Point Objective): The maximum acceptable amount of data loss measured in time.
D: RTO (Recovery Time Objective): The target time set for the recovery of IT and business activities after a disaster.
Conclusion:
MTBF is a crucial metric in disaster recovery and system reliability, helping organizations plan maintenance and predict system performance.
