What is TLB for? Why TLB? Given the following number, what is theeffective memory access time?

vodomira [7]

Answer:

A lookaside buffer translation (TLB) is a memory cache that reduces the time it takes to access a user memory place. TLB includes the most lately used page table entries.

TLB is used to overcome the issue of sizes at the time of paging. Page Table Entry (PTE) is used for framing the memory ,but it uses two references one for finding the frame number and the other for the address specified by frame number.

<u>Formula for finding effective memory access time-</u>

Effective Memory Access Time = (TLB access_time+Memory Access Time)*hit ratio + (TLB access_time+2*Memory Access Time)*(miss ratio)

Given in question,

Hit ratio = 0.90

Memory Access Time = 150ns

TLB access time= 5ns

Effective Memory Access Time = (TLB access_time+Memory Access Time)*hit ratio + (TLB access_time+2*Memory Access Time)*(miss ratio)

=(5+150) * 0.90 + (5+2*150)*(1-0.90)

=155 * 0.90 + (305*0.1)

=139.5 + 30.5

= 170ns

Which Internet connection can have speeds around 1 Gbps?<br> Cable<br> DSL<br> Fiber<br> Satellite

Alexus [3.1K]

<h2>Answer:</h2>

<u>Fiber</u> Internet connection has speeds around 1 Gbps.

<h2></h2><h2>Explanation:</h2>

Fiber Internet connection is the modern way of transmitting and receiving data. As obvious from the name Optical Fiber consists of thin fibers that are extremely thin (as a human hair). They transmit data with the beam of light that make this transmission speedy as well as reliable. Therefore they provide the download speed ranging from 25 Mbps to 1 Gbps.

Fiber Internet connection is considered best for the small businesses as it provides high bandwidth for transmission. The best part of this connection is that it is made of glass and plastic that do not conduct heat or electricity that means the fiber is safe from the damages as well.

After a failover cluster is created, which of the following is a task to be performed when configuring the failover cluster? (Ch

Lynna [10]

Answer: (B) Configure the cluster networks

(C) Configure the quorum model

Explanation:

When the fail-over cluster has been created then, configure the cluster network and quorum model tasks performed during configuring the fail-over cluster.

The quorum model are flexible in the window server. We can configure the quorum model when we need to modified the quorum model configuration for the cluster. The software cluster are automatically configure quorum model for the new cluster that is based on the availability of the share storage.

When configuring the fail-over cluster we can perform various cluster network tasks in the system.

Which of these AWS resources cannot be monitored using VPC Flow logs?a) Vâ€‹PCb) Aâ€‹ subnet in a VPCc) A network interface atta

WINSTONCH [101]

Answer:

d) An Internet Gateway attached to VPC.

Explanation:

Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.

Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.

Cloud computing comprises of three (3) service models and these are;

1. Platform as a Service (PaaS).

2. Infrastructure as a Service (IaaS).

3. Software as a Service (SaaS).

Amazon Web Services (AWS) is an example of a cloud computing platform that offer its users a global cloud-based products and services such as storage, security, computing resources, database, analytics and management tools etc.

Some of the Amazon Web Services (AWS) resources that can be monitored using virtual private cloud (VPC) Flow logs includes;

I. A VPC

II. A subnet in a VPC

III. A network interface attached to EC2

However, an Internet Gateway attached to VPC is an AWS resource that cannot be monitored using virtual private cloud (VPC) Flow logs.
