Question 121

A technician receives a report of system utilization:

Which of the following additional resources should the technician add FIRST given the trend data shown above?

A.CPU
B.RAM
C.Bandwidth
D.Disk

Question 122

In an existing IaaS instance, it is required to deploy a single application that has different versions.
Which of the following should be recommended to meet this requirement?

A.Deploy using containers
B.Install a Type 2 hypervisor
C.Enable SR-IOV on the host
D.Create snapshots

Question 123

An application deployment team has observed delays in deployments and has asked the cloud administrator to evaluate the issue. Below is the result of a latency test that was conducted by the cloud administrator from offices located in the following regions:
* Asia-Pacific (APAC)
* Europe, the Middle East, and Africa (EMEA)
* Americas
Tests were conducted from each location, and the results are shown below:

Which of the following locations needs to be investigated further?

A.* Connectivity from APAC to APAC regions
* Connectivity from APAC to EMEA and US - North
B.* Connectivity from APAC to all regions
* Connectivity from Americas to all regions
C.* Connectivity from EMEA to all regions
* Connectivity from APAC to APAC and EMEA regions
D.* Connectivity from APAC to EMEA and Americas regions
* Connectivity from EMEA to all regions

Correct Answer: D

The latency test results show that the connectivity from APAC to EMEA and Americas regions has the highest latency values, ranging from 162 ms to 380 ms. This indicates that there is a significant delay in the network communication between these regions, which could affect the performance and availability of the cloud services. The connectivity from EMEA to all regions also has high latency values, ranging from 60 ms to 328 ms, which could also cause issues for the application deployment team. Therefore, these locations need to be investigated further to identify and resolve the root cause of the network latency.
Some possible causes of network latency are :
Congestion: The network bandwidth may be insufficient to handle the volume of traffic, resulting in packet loss, retransmission, and queuing delays.
Distance: The physical distance between the source and destination nodes may increase the propagation delay, which is the time it takes for a signal to travel through a medium.
Routing: The network topology and configuration may affect the number and quality of hops that a packet takes to reach its destination, resulting in transmission and processing delays.
Hardware: The performance and capacity of the network devices, such as routers, switches, firewalls, and servers, may affect the speed and efficiency of data processing and delivery.
Some possible solutions to reduce network latency are :
Scaling: The network resources can be increased or optimized to handle the traffic demand, such as adding more bandwidth, load balancers, or caching servers.
Location: The network nodes can be placed closer to each other or to the end users, such as using edge computing, content delivery networks (CDNs), or regional cloud data centers.
Routing: The network routes can be improved or optimized to reduce the number and distance of hops, such as using direct peering, dedicated circuits, or software-defined networking (SDN).
Hardware: The network devices can be upgraded or replaced with faster and more reliable ones, such as using solid-state drives (SSDs), fiber-optic cables, or 5G technology.

Question 124

An integration application that communicates between different application and database servers is currently hosted on a physical machine. A P2V migration needs to be done to reduce the hardware footprint. Which of the following should be considered to maintain the same level of network throughput and latency in the virtual server?

A.Upgrading the physical server NICs to support 10Gbps
B.Adding more vCPU
C.Enabling SR-IOV capability
D.Increasing the VM swap/paging size

Question 125

An organization is hosting a cloud-based web server infrastructure that provides web-hosting solutions. Sudden continuous bursts of traffic have caused the web servers to saturate CPU and network utilizations.
Which of the following should be implemented to prevent such disruptive traffic from reaching the web servers?

A.DDoS protection
B.Solutions to perform NAC and DLP
C.QoS on the network
D.A solution to achieve microsegmentation
