NEW QUESTION # 186
Which of the following routing protocols uses an autonomous system number?
- A. EIGRP
- B. OSPF
- C. BGP
- D. IS-IS
Answer: C
Explanation:
BGP (Border Gateway Protocol) uses an Autonomous System (AS) number for its operations. An AS is a collection of IP networks and routers under the control of a single organization that presents a common routing policy to the Internet. BGP is used to exchange routing information between different ASes on the Internet, making it the only protocol among the listed options that uses an AS number.Reference: CompTIA Network+ study materials and RFC 4271.
NEW QUESTION # 187
A network technician is configuring the company's network of 100 Mbps Layer 2 switches. The technician wants increased throughput for the uplinks between switches. The technician connects multiple redundant links between the switches. Which of the following should the technician configure?
- A. Native VLAN
- B. Spanning Tree Protocol
- C. Switch Virtual Interfaces
- D. First Hop Redundancy Protocol
Answer: B
Explanation:
When multiple redundant links exist between switches, Spanning Tree Protocol (STP) is required to prevent switching loops. STP blocks redundant paths but can allow aggregation if configured with protocols like LACP.
B). SVIs provide Layer 3 interfaces, not loop prevention.
C). Native VLAN defines the untagged VLAN but does not manage loops.
D). FHRP (VRRP, HSRP, GLBP) provides gateway redundancy, not switch uplink management.
References (CompTIA Network+ N10-009):
Domain: Network Infrastructure - STP, redundancy, loop prevention.
NEW QUESTION # 188
A network engineer is setting up a new VoIP network for a customer. The current network is segmented only for computers and servers. No additional switchports can be used in the new network. Which of the following does the engineer need to do to configure the network correctly? (Select two).
- A. Change network translation definitions
- B. Set up voice VLANs
- C. Enable 802.1Q
- D. Reconfigure the DNS
- E. Implement a routing protocol
- F. Place devices in the perimeter network
Answer: B,C
Explanation:
To support VoIP on a network with limited switchports, the engineer should configure voice VLANs and enable 802.1Q tagging. Voice VLANs allow VoIP traffic to be prioritized and isolated from data traffic even when sharing the same physical port. 802.1Q is used for VLAN tagging, enabling multiple VLANs over a single physical link.
From Andrew Ramdayal's guide:
"Voice VLANs allow IP phones and computers to share the same physical switch port while keeping their traffic separate. 802.1Q is used to tag VLAN traffic so that it can be appropriately routed and prioritized."
NEW QUESTION # 189
A network engineer configures the network settings in a new server as follows:
IP address = 192.163.1.15
Subnet mask = 255.255.255.0
Gateway = 192.163.1.255
The server can reach other hosts on the same subnet successfully, but it cannot reach hosts on different subnets. Which of the following is most likely configured incorrectly?
- A. Default route
- B. Gateway
- C. IP address
- D. Subnet mask
Answer: B
Explanation:
The default gateway for a network should be an IP address within the subnet, but not the broadcast address. In this case:
IP: 192.163.1.15
Subnet Mask: 255.255.255.0
This means the network range is: 192.163.1.0 - 192.163.1.255
192.163.1.255 is the broadcast address for this subnet, so it cannot be used as a gateway.
Hence, the device fails to communicate outside its subnet because it's trying to use a broadcast address as its gateway.
# The issue is clearly with the gateway configuration.

Explanation:
Network Health:
WAN 2 appears to have a lower average latency and loss percentage, which would make it the preferred WAN station for VoIP traffic. VoIP traffic requires low latency and packet loss to ensure good voice quality and reliability. WAN 1 seems to have higher RAM and processor usage, which could also affect the performance of VoIP traffic.
Here's the summary of the key metrics for WAN 1 and WAN 2 from the image provided:
WAN 1:
Uplink Speed: 10G
Total Usage: 26.969GB Up / 1.748GB Down
Average Throughput: 353MBps Up / 23.42MBps Down
Loss: 2.51%
Average Latency: 24ms
Jitter: 9.5ms
WAN 2:
Uplink Speed: 1G
Total Usage: 930GB Up / 138GB Down
Average Throughput: 12.21MBps Up / 1.82MBps Down
Loss: 0.01%
Average Latency: 11ms
Jitter: 3.9ms
For VoIP traffic, low latency and jitter are particularly important to ensure voice quality. While WAN 1 has higher bandwidth and throughput, it also has higher latency and jitter compared to WAN 2. However, WAN 2 has much lower loss, lower latency, and lower jitter, which are more favorable for VoIP traffic that is sensitive to delays and variation in packet arrival times.
Given this information, WAN 2 would generally be preferred for VoIP traffic due to its lower latency, lower jitter, and significantly lower loss percentage, despite its lower bandwidth compared to WAN 1. The high bandwidth of WAN 1 may be more suitable for other types of traffic that are less sensitive to latency and jitter, such as bulk data transfers.
Device Monitoring:
the device that is experiencing connectivity issues is the APP Server or Router 1, which has a status of Down. This means that the server is not responding to network requests or sending any dat a. You may want to check the physical connection, power supply, and configuration of the APP Server to troubleshoot the problem.
NEW QUESTION # 191
A network engineer needs to virtualize network services, including a router at a remote branch location. Which of the following solutions meets the requirements?
- A. VRF
- B. VPC
- C. NFV
- D. VLAN
Answer: C
Explanation:
Network Functions Virtualization (NFV): NFV is a technology that virtualizes network services like routing, firewalls, and load balancers. It allows these services to run on virtual machines rather than requiring dedicated hardware. This is ideal for remote branch locations where deploying physical devices is costly and complex.
VRF (B): Virtual Routing and Forwarding is used for segmenting routing tables but does not virtualize services.
VLAN (C): Virtual Local Area Networks help segregate broadcast domains but are unrelated to virtualizing network functions.
VPC (D): Virtual Private Cloud is used for cloud computing but does not pertain to virtualizing network services.

NEW QUESTION # 193
Which of the following should be configured so users can authenticate to a wireless network using company credentials?
- A. SAML
- B. MFA
- C. RADIUS
- D. SSO
Answer: C
Explanation:
RADIUS (Remote Authentication Dial-In User Service) is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service. RADIUS is often used to manage access to wireless networks, enabling users to authenticate with their company credentials, ensuring secure access to the network.Reference: CompTIA Network+ study materials.
NEW QUESTION # 194
Due to concerns around single points of failure, a company decided to add an additional WAN to the network.
The company added a second MPLS vendor to the current MPLS WAN and deployed an additional WAN router at each site. Both MPLS providers use OSPF on the WAN network, and EIGRP is run internally. The first site to go live with the new WAN is successful, but when the second site is activated, significant network issues occur. Which of the following is the most likely cause for the WAN instability?
- A. A changed CDP neighbor
- B. A switching loop
- C. Asymmetrical routing
- D. An incorrect IP address
Answer: C
Explanation:
Asymmetrical routing occurs when packets take different paths to and from the destination, leading to instability in network communication. The use of two different MPLS providers with OSPF can lead to this type of routing issue, especially if the paths aren't carefully configured and managed. This can cause unexpected routing behaviors and instability in a dual-WAN setup. (Reference: CompTIA Network+ Study Guide, Chapter on Network Routing)

Which of the following is causing the user's issue?
- A. Failed root bridge
- B. Unreachable gateway
- C. Poor upstream routing
- D. Incorrect DNS
Answer: B
Explanation:
The customer can accesslocal resources(a database server), which meanslocal networking is working.
However, the inability to reach the internet suggests an issue with thedefault gateway. If thedefault gateway is unreachable, packets will not be routed outside the local network.
Breakdown of Options:
* A. Incorrect DNS-DNS issueswould cause problemsresolving domain names, but the user should still be able to access external resources via IP addresses.
* B. Unreachable gateway-#Correct answer.If thedefault gateway is incorrect or unreachable, the devicecannot route traffic to the internet.
* C. Failed root bridge-STP (Spanning Tree Protocol) failurescauseswitching issues, but the user can still access local devices, meaning STP is not the problem.
* D. Poor upstream routing- Wouldaffect the entire network, not just one user.
NEW QUESTION # 198
Which protocol provides encryption, integrity, and authentication for data inside a VPN tunnel?
- A. IKE
- B. GRE
- C. ESP
- D. SSH
Answer: C
Explanation:
ESP (Encapsulating Security Payload) is an IPsec protocol that provides encryption, integrity, and authentication for data inside a VPN tunnel. It ensures that all tunneled traffic is encrypted.
* B. SSH secures remote terminal sessions, not site-to-site VPN tunnels.
* C. GRE (Generic Routing Encapsulation) provides encapsulation but does not encrypt data.
* D. IKE (Internet Key Exchange) negotiates keys and establishes the IPsec tunnel but does not encrypt the payload itself.
References (CompTIA Network+ N10-009):
* Domain: Network Security - VPN protocols, IPsec (AH vs. ESP), encryption in transit.
NEW QUESTION # 199
A network engineer is designing a secure communication link between two sites. The entire data stream needs to remain confidential. Which of the following will achieve this goal?
- A. AH
- B. IKE
- C. GRE
- D. ESP
Answer: D
Explanation:
Definition of ESP (Encapsulating Security Payload):
ESP is a part of the IPsec protocol suite designed to provide confidentiality, integrity, and authenticity of data by encrypting the payload and optional ESP trailer.
Ensuring Confidentiality:
Encryption: ESP encrypts the payload, ensuring that the data remains confidential during transmission. Only authorized parties with the correct decryption keys can access the data.
Modes of Operation: ESP can operate in transport mode (encrypts only the payload) or tunnel mode (encrypts the entire IP packet), both providing strong encryption to secure data between sites.
