A company needs to virtualize a replica of its internal physical network without changing the logical topology and the way that devices behave and are managed. Which of the following technologies meets this requirement?

• A. NFV
• B. SDWAN
• C. VIP
• D. MPLS

Answer: A

Explanation:
Network Function Virtualization (NFV) is a technology that allows for the virtualization of a replica of a network's physical topology and the way it behaves without changing the logical topology and the way that devices are managed. NFV allows for the virtualization of network functions such as routers, firewalls, and switches, resulting in increased flexibility and scalability. This makes NFV an ideal technology for companies looking to virtualize a replica of their internal physical network.

NEW QUESTION 3

Which of the following would a network administrator configure to set NTP settings for a specific subnet within DHCP?

• A. Reservation
• B. Lease time
• C. Scope options
• D. Exclusion range

Answer: C

Explanation:
The network administrator would configure scope options to set NTP settings for a specific subnet within DHCP. Scope options are settings that apply to a range of IP addresses that are assigned by a DHCP server. Scope options can include parameters such as default gateway, DNS server, and NTP server. By configuring the NTP server option for a specific scope, the network administrator can ensure that the devices in that subnet synchronize their clocks with the same time source.

NEW QUESTION 10

Which of the following use cases would justify the deployment of an mGRE hub-and-spoke topology?

• A. An increase in network security using encryption and packet encapsulation
• B. A network expansion caused by an increase in the number of branch locations to the headquarters
• C. A mandatory requirement to increase the deployment of an SDWAN network
• D. An improvement in network efficiency by increasing the useful packet payload

Answer: B

Explanation:

mGRE (Multipoint GRE) is a type of GRE (Generic Routing Encapsulation) tunnel that allows a single interface to support multiple tunnel endpoints, instead of having to configure a separate point-to-point tunnel for each destination. mGRE simplifies the configuration and management of large-scale VPN networks, such as DMVPN (Dynamic Multipoint VPN), which is a Cisco technology that uses mGRE, NHRP (Next Hop Resolution Protocol), and IPsec to create secure and dynamic VPN connections between a hub and multiple spokes1.
A network expansion caused by an increase in the number of branch locations to the headquarters would justify the deployment of an mGRE hub-and-spoke topology, because it would reduce the complexity and overhead of configuring and maintaining multiple point- to-point tunnels between the hub and each spoke. mGRE would also enable spoke-to- spoke communication without having to go through the hub, which would improve the network performance and efficiency23.
The other options are not directly related to the use case of mGRE hub-and-spoke topology. An increase in network security using encryption and packet encapsulation can be achieved by using IPsec, which is a separate protocol that can be applied to any type of GRE tunnel, not just mGRE. A mandatory requirement to increase the deployment of an SDWAN network can be met by using various technologies and vendors, not necessarily mGRE or DMVPN. An improvement in network efficiency by increasing the useful packet payload can be achieved by using various techniques, such as compression, fragmentation, or QoS, not specifically mGRE.

NEW QUESTION 11

Which of the following fiber connector types is the most likely to be used on a network interface card?

• A. LC
• B. SC
• C. ST
• D. MPO

Answer: A

Explanation:
LC (local connector) is the most likely fiber connector type to be used on a network interface card, because it is a small form factor connector that can fit more interfaces on a single card. LC connectors use square connectors that have a locking mechanism on the top, similar to an RJ45 copper connector. LC connectors are also compatible with SFP (small form-factor pluggable) modules that are often used to link a gigabit Ethernet port with a fiber network12.

NEW QUESTION 12

An organization with one core and five distribution switches is transitioning from a star to a full-mesh topology Which of the following is the number of additional network connections needed?

• A. 5
• B. 7
• C. 10
• D. 15

Answer: C

Explanation:
10 additional network connections are needed to transition from a star to a full-mesh topology. A star topology is a network topology where each device is connected to a central device, such as a switch or a hub. A full-mesh topology is a network topology where each device is directly connected to every other device. The number of connections needed for a full-mesh topology can be calculated by the formula n(n-1)/2, where n is the number of devices. In this case, there are six devices (one core and five distribution switches), so the number of connections needed for a full-mesh topology is 6(6-1)/2 = 15. Since there are already five connections in the star topology (one from each distribution switch to the core switch), the number of additional connections needed is 15 - 5 = 10.

NEW QUESTION 13

On a network with redundant switches, a network administrator replaced one of the switches but was unable to get a connection with another switch. Which of the following should the administrator chock after successfully testing the cable that was wired for TIA/EIA-568A on both ends?

• A. If MDIX is enabled on the new switch
• B. If PoE is enabled
• C. If a plenum cable is being used
• D. If STP is disabled on the switches

Answer: A

Explanation:
Auto-MDIX (or medium dependent interface crossover) is a feature that automatically detects the type of cable connection and configures the interface accordingly
(i.e. straight-through or crossover). This ensures that the connection between the two switches is successful. This is referenced in the CompTIA Network+ Study Manual, page 519.

NEW QUESTION 14

Which of the following can be used to identify users after an action has occurred?

• A. Access control vestibule
• B. Cameras
• C. Asset tag
• D. Motion detectors

Answer: B

Explanation:
Cameras can be used to identify users after an action has occurred by recording their faces, clothing, or other distinctive features. Cameras are often used as a deterrent and a forensic tool for security purposes. Access control vestibules, asset tags, and motion detectors are not effective in identifying users, but rather in controlling access, tracking assets, and detecting movement.

• A. QSFP
• B. QSFP+
• C. SFP
• D. SFP+

Answer: D

Explanation:
SFP+ is a type of optical transceiver that supports 10G single-channel transmission over fiber optic cables. SFP+ stands for small form-factor pluggable plus, and it is compatible with SFP slots on switches and routers.

NEW QUESTION 16

A customer reports there is no access to resources following the replacement of switches. A technician goes to the site to examine the configuration and discovers redundant links between two switches. Which of the following is the reason the network is not functional?

• A. The ARP cache has become corrupt.
• B. CSMA/CD protocols have failed.
• C. STP is not configured.
• D. The switches are incompatible models

Answer: C

Explanation:
The reason the network is not functional is that STP (Spanning Tree Protocol) is not configured on the switches. STP is a protocol that prevents loops in a network topology by blocking redundant links between switches. If STP is not enabled, the switches will forward broadcast frames endlessly, creating a broadcast storm that consumes network resources and disrupts communication.
