CompTIA Security+ Question G-31

A network administrator recently updated various network devices to ensure redundancy throughout the network. If an interface on any of the Layer 3 devices were to go down, traffic will still pass through another interface and the production environment would be unaffected. This type of configuration represents which of the following concepts?

A. High availability
B. Load balancing
C. Backout contingency plan
D. Clustering

Answer: A

Explanation:
High availability (HA) refers to the measures used to keep services and systems operational during an outage. In short, the goal is to provide all services to all users, where they need them and when they need them. With high availability, the goal is to have key services available 99.999 percent of the time (also known as five nines availability).

CompTIA Network+ Question C-26

Network segmentation provides which of the following benefits?

A. Security through isolation
B. Link aggregation
C. Packet flooding through all ports
D. High availability through redundancy

Correct Answer: A

Explanation:
Network segmentation in computer networking is the act or profession of splitting a computer network into subnetworks, each being a network segment. Advantages of such splitting are primarily for boosting performance and improving security through isolation.
Advantages of network segmentation:
Improved security: Broadcasts will be contained to local network. Internal network structure will not be visible from outside
Reduced congestion: Improved performance is achieved because on a segmented network there are fewer hosts per subnetwork, thus minimizing local traffic Containing network problems: Limiting the effect of local failures on other parts of network
