Question 3.
A growing e-commerce company is considering various strategies to ensure its web servers can handle sudden traffic surges without an impact on site availability.
The company is assessing methods that distribute incoming traffic across multiple servers.
Which strategy should the company implement to dynamically allocate the load based on real-time traffic and server conditions?
answer
Active server pages
Active Directory
Active load balancing
Incorrect answer:
Passive load balancing
Correct Answer:
Active load balancing
Question 4.
A growing e-commerce company wants to implement a strategy that evenly distributes incoming traffic across multiple servers without constantly monitoring server loads or making adjustments based on real-time conditions.
Which strategy should this company implement to manage load distribution in this manner?
answer
Active Directory
Active Server Pages
Active load balancing
Passive load balancing
Correct Answer:
Passive load balancing
Question 5.
A security consultant assesses a company’s server room to determine how well it can maintain operations during power interruptions. The consultant evaluates the integration of power distribution units (PDUs) and backup power generators within the security architecture.
Considering the goal of ensuring resilience and recovery in the server room during power interruptions, which primary role does the backup power generator play in conjunction with the PDU?
answer
It ensures power load balancing across multiple servers.
It filters and stabilizes the power before it is distributed by the PDU.
It instantly supplies power to PDUs to prevent any momentary lapse during an outage.
It provides a prolonged source of power to the PDUs after the UPS system depletes its immediate resources.
Correct Answer:
It provides a prolonged source of power to the PDUs after the UPS system depletes its immediate resources.
Question 6.
A data center manager is evaluating the resilience and recovery capabilities of a company’s server room. The manager wants to ensure that in the event of power fluctuations or outages, the company’s servers remain operational and maintain data integrity.
The manager focuses on the role of power distribution units (PDUs) and Uninterruptible Power Supplies (UPSs) in this context.
In enhancing the resilience and recovery capabilities of the server room against power interruptions, which primary function does the UPS provide to the servers that directly support this goal?
answer
It provides temporary power during an outage, allowing for a graceful shutdown or transition to backup generators.
It monitors power usage and sends alerts for overconsumption.
It distributes power to multiple servers simultaneously.
It filters power to remove noise and surges.
Correct Answer:
It provides temporary power during an outage, allowing for a graceful shutdown or transition to backup generators.
Question 7.
An organization operates a large data center that supports critical business operations. Recently, the organization has struggled with frequent power interruptions leading to downtime and data loss.
To address this issue, the chief information security officer (CISO) decides to review the data center’s resilience and recovery strategies, particularly emphasizing backup power.
To increase the resilience and recovery capabilities of the data center and ensure operations continue even during a power failure, which of the following options should the CISO consider? (Select two.)
answer
Implement load balancing.
Enhance the firewall system.
Implement a UPS.
Purchase additional servers.
Deploy a dual power supply unit in each server.
Correct Answer:
Implement a UPS.
Correct Answer:
Deploy a dual power supply unit in each server.
Question 8.
What is a significant advantage of using an active/passive clustering configuration in a network?
answer
-The active node can access the cookies or other information used to establish the login.
-Both nodes process connections concurrently, maximizing hardware capacity.
-The public IP used to access the service is shared between the two instances in the cluster.
-The performance is not adversely affected during failover.
Correct Answer:
The performance is not adversely affected during failover.
Question 9.
What is a primary function of application clustering in a network?
answer
-It distributes client requests across available server nodes.
-It processes connections concurrently in an active/active cluster.
-It allows servers in the cluster to communicate session information to one another.
-It enables the active node to “own” the virtual IP and respond to connections.
Correct Answer:
It allows servers in the cluster to communicate session information to one another.
Question 10.
What is the primary function of the Common Address Redundancy Protocol (CARP) in a network?
answer
To process connections concurrently in an active/active cluster.
To communicate session information between servers in a cluster.
To enable the active node to “own” the virtual IP and respond to connections.
To distribute client requests across available server nodes.
Correct Answer:
To enable the active node to “own” the virtual IP and respond to connections.
