Question 106

Which of the following refers to the ability of a system to automatically scale resources up or down in real time based on demand?

A.Scalability
B.Software as a Service
C.Hybrid cloud
D.Elasticity

Correct Answer: D

Elasticity is the ability of a system (often in cloud environments) to automatically scale resources up or down in real time based on demand.
* A. Scalability means the ability to grow over time but not necessarily dynamically.
* B. SaaS is a service model, not a resource-allocation concept.
* C. Hybrid cloud is a deployment model, not a performance behavior.
References (CompTIA Network+ N10-009):
* Domain: Networking Concepts - Cloud computing, elasticity vs. scalability.

Question 107

Which of the following internal routing protocols is best characterized as having fast convergence and being loop-free?

A.BGP
B.STP
C.OSPF
D.RIP

Correct Answer: C

The correct answer is OSPF (Open Shortest Path First). OSPF is a link-state routing protocol known for its fast convergence and use of the Dijkstra algorithm to calculate the shortest loop-free path. It efficiently scales to large enterprise networks and avoids routing loops by maintaining a complete topology map.
A . BGP is primarily an external routing protocol used between ISPs, not internal.
B . STP is not a routing protocol; it prevents loops at Layer 2.
D . RIP is an older distance-vector protocol with slower convergence and a maximum hop limit of 15.
OSPF's design makes it the preferred internal gateway protocol (IGP) for medium-to-large organizations requiring speed and loop-free reliability.

Question 108

Which of the following requires network devices to be managed using a different set of IP addresses?

A.Console
B.Split tunnel
C.Jump box
D.Out of band

Correct Answer: D

Out-of-band (OOB) management refers to using a dedicated management network that is physically separate from the regular data network. This management network uses a different set of IP addresses to ensure that management traffic is isolated from user data traffic, providing a secure way to manage network devices even if the main network is down or compromised.

Question 109

Which of the following ports should a network administrator enable for encrypted login to a network switch?

A.22
B.23
C.80
D.123

Correct Answer: A

Port 22 is used for Secure Shell (SSH), which enables encrypted remote login and command execution on network devices.
Port 23 = Telnet (unencrypted)
Port 80 = HTTP
Port 123 = NTP
From Andrew Ramdayal's guide:
"SSH uses port 22 to provide secure command-line access to devices such as switches and routers. Unlike Telnet (port 23), SSH encrypts session traffic, making it the preferred method for remote administration."

Question 110

Which of the following should a network administrator configure when adding OT devices to an organization's architecture?

A.Honeynet
B.Data-at-rest encryption
C.Time-based authentication
D.Network segmentation

Correct Answer: D

Network segmentation involves dividing a network into smaller segments or subnets. This is particularly important when integrating OT (Operational Technology) devices to ensure that these devices are isolated from other parts of the network. Segmentation helps protect the OT devices from potential threats and minimizes the impact of any security incidents. It also helps manage traffic and improves overall network performance.References:CompTIA Network+ study materials.
