CompTIA Network+ Certification Exam Sample Questions (Q168-Q173):

NEW QUESTION # 168
A network engineer performed a migration to a new mail server. The engineer changed the MX record, verified the change was accurate, and confirmed the new mail server was reachable via the IP address in the A record. However, users are not receiving email. Which of the following should the engineer have done to prevent the issue from occurring?

A. Update the NS record to reflect the IP address change.
B. Reduce the TTL record prior to the MX record change.
C. Change the email client configuration to match the MX record.
D. Perform a DNS zone transfer prior to the MX record change.

Answer: B

Explanation:
* Understanding TTL (Time to Live):
* TTL is a value in a DNS record that tells how long that record should be cached by DNS servers and clients. A higher TTL value means that the record will be cached longer, reducing the load on the DNS server but delaying the propagation of changes.
* Impact of TTL on DNS Changes:
* When an MX record change is made, it may take time for the change to propagate across all DNS servers due to the TTL setting. If the TTL is high, old DNS information might still be cached, leading to email being directed to the old server.
* Best Practice Before Making DNS Changes:
* To ensure that changes to DNS records propagate quickly, it is recommended to reduce the TTL value to a lower value (such as 300 seconds or 5 minutes) well in advance of making the changes.
This ensures that any cached records will expire quickly, and the new records will be used sooner.
* Verification of DNS Changes:
* After reducing the TTL and making the change to the MX record, it is important to verify the propagation using tools like dig or nslookup.
* Comparison with Other Options:
* Change the email client configuration to match the MX record: Email clients generally do not need to match the MX record directly; they usually connect to a specific mail server specified in their settings.
* Perform a DNS zone transfer prior to the MX record change: DNS zone transfers are used to replicate DNS records between DNS servers, but they are not related to the propagation of individual record changes.
* Update the NS record to reflect the IP address change: NS records specify the DNS servers for a domain and are not related to MX record changes.

NEW QUESTION # 169
A network administrator is configuring a new switch and wants to ensure that only assigned devices can connect to the switch. Which of the following should the administrator do?

A. Implement a captive portal.
B. Enable port security.
C. Disable unnecessary services.
D. Configure ACLs.

Answer: B

Explanation:
To ensure that only assigned devices can connect to a switch, the network administrator should enable port security. Port security restricts port access based on MAC addresses, allowing only pre-configured devices to connect to the network. This helps prevent unauthorized devices from gaining access to the network. Other options like configuring ACLs, implementing a captive portal, or disabling unnecessary services serve different security purposes and do not directly restrict physical port access based on device identity.

NEW QUESTION # 170
Which of the following network ports is used when a client accesses an SFTP server?

A. 0
B. 1
C. 2
D. 3

Answer: C

Explanation:
SFTP (Secure File Transfer Protocol) operates over port 22, using SSH (Secure Shell) encryption for secure file transfers.
Breakdown of Options:
A: 22 - Correct answer. SFTP runs over SSH (port 22) for secure file transfers.
B: 80 - Used for HTTP, not SFTP.
C: 443 - Used for HTTPS (secure web traffic).
D: 3389 - Used for RDP (Remote Desktop Protocol).

NEW QUESTION # 171
A systems administrator is configuring a new device to be added to the network. The administrator is planning to perform device hardening prior to connecting the device. Which of the following should the administrator do first?

A. Change the default admin passwords.
B. Update the network ACLs.
C. Place the device in a screened subnet.
D. Enable content filtering.

Answer: A

Explanation:
Changing default admin passwords is a fundamental first step in device hardening to prevent unauthorized access.

NEW QUESTION # 172
A network administrator is implementing security zones for each department. Which of the following should the administrator use to accomplish this task?

A. Port security
B. ACLs
C. Content filtering
D. NAC

Answer: B

Explanation:
Understanding ACLs:
Access Control Lists (ACLs): A set of rules used to control network traffic and restrict access to network resources by filtering packets based on IP addresses, protocols, or ports.
Implementing Security Zones:
Defining Zones: ACLs can be used to create security zones by applying specific rules to different departments, ensuring that only authorized traffic is allowed between these zones.
Control Traffic: ACLs control inbound and outbound traffic at network boundaries, enforcing security policies and preventing unauthorized access.
Comparison with Other Options:
Port Security: Limits the number of devices that can connect to a switch port, preventing MAC address flooding attacks, but not used for defining security zones.
Content Filtering: Blocks or allows access to specific content based on predefined policies, typically used for web filtering rather than network segmentation.
NAC (Network Access Control): Controls access to the network based on the security posture of devices but does not define security zones.
Implementation Steps:
Define ACL rules based on the requirements of each department.
Apply these rules to the appropriate network interfaces or firewall policies to segment the network into security zones.
