Question #171
Which of the following does a full-tunnel VPN provide?
- A . Lower bandwidth requirements
- B . The ability to reset local computer passwords
- C . Corporate Inspection of all network traffic
- D . Access to blocked sites
Correct Answer: C
C
Explanation:
A full-tunnel VPN routes all of a user’s network traffic through the corporate network. This means that the organization can inspect all network traffic for security and compliance purposes, as all data is tunneled through the VPN, allowing for comprehensive monitoring and inspection.
Reference: CompTIA Network+ study materials.

Question #172
A company is expanding to another floor in the same building. The network engineer configures a new switch with the same VLANs as the existing stack. When the network engineer connects the new switch to the existing stack, all users lose connectivity.
Which of the following is the MOST likely reason?
- A . The new switch has unused ports disabled
- B . The new switch does not have a default gateway
- C . The new switch is connected to an access port
- D . The new switch is in a spanning tree loop
Correct Answer: D
D
Explanation:
This describes a Spanning Tree Protocol (STP) loop. If STP isn’t correctly configured or a redundant link is added without STP protection, it causes broadcast storms and network outages.

Question #173
A network administrator needs to divide 192.168.1.0/24 into two equal halves.
Which of the following subnet masks should the administrator use?
- A . 255.255.0.0
- B . 255.255.254.0
- C . 255.255.255.0
- D . 255.255.255.128
Correct Answer: D
D
Explanation:
Understanding Subnetting:
Original Network: 192.168.1.0/24 has a subnet mask of 255.255.255.0, which allows for 256 IP addresses (including network and broadcast addresses).
Objective: Divide this network into two equal subnets.
Calculating Subnet Mask:
New Subnet Mask: To divide 192.168.1.0/24 into two equal halves, we need to borrow one bit from the host portion of the address, changing the subnet mask to 255.255.255.128 (/25).
Subnet Breakdown:
First Subnet: 192.168.1.0/25 (192.168.1.0 – 192.168.1.127) Second Subnet: 192.168.1.128/25 (192.168.1.128 – 192.168.1.255) Verification:
Each subnet now has 128 IP addresses (126 usable IP addresses, excluding the network and broadcast addresses).
Comparison with Other Options:

Question #174
A network administrator has been monitoring the company’s servers to ensure that they are available.
Which of the following should the administrator use for this task?
- A . Packet capture
- B . Data usage reports
- C . SNMP traps
- D . Configuration monitoring
Correct Answer: C
C
Explanation:
To monitor server availability, SNMP traps are the best choice. SNMP (Simple Network Management Protocol) allows devices to send alerts (traps) when certain conditions are met, such as server downtime or high resource usage.
