You run a website called Offhand that sells exclusive handmade home decor items. On Mother’s Day, the website unexpectedly receives a burst of traffic following the marketing campaign designed for this occasion. Thankfully, you are equipped with a good cloud service model and hence you are able to increase the cloud resources the website needs without disrupting your web services. Which of the following cloud characteristics helped you manage the situation easily?a. rapid elasticityb. measured servicec. broad network accessd. resource pooling
rapid elasticity
You already have a running network in your organization, but because of the recent influx of network traffic and as a network engineer, you want to take a more organized approach in designing the network so that every device can function optimally. You have decided to add highly efficient multilayer switches to pass traffic in and out of a few backbone ports as quickly as possible.

The Centre for Equity Studies is a not-for-profit organization in Staten Island, New York, working in the human rights sector. Currently, because of the pandemic, the employees work from home. They work in association with three other initiatives, all of them involved in the same sector. hence, there are a lot of resources that are routinely shared among all of them but not with the general public. You have been assigned the task of selecting one cloud model, keeping in mind the working conditions and the requirements of the users. Which of the following would suit this organization the most?a. a public cloudb. a community cloudc. a hybrid cloudd. a private cloud
A community cloud

Lewis has been hired as an assistant to the head network administrator.

Ross is running a small data entry back office, for which he has contracted you for network management. Ross has made it very clear that because he has just started the company he wants to cut down on expenses wherever he can. One such option involves the router he wants to exchange the router with a similar but less expensive alternative. Which of the following will you refer to Ross in such a situation?a. a layer 3 switchb. a root portc. an SDN controllerd. storm control
A layer 3 switch
Which of the following protocols allows a pool of computers or interfaces to share one or more IP addresses?a. TRILLb. CARPc. SPBd. LACP
CARP
You have been working with an ISP as a network engineer. You have made multiple WAN connections over a period of time. Recently, you have received complaints from various clients about network failure, which is having an effect on their day-to-day business. This network failure is primarily caused by some bugs in a few of the network devices. In order to protect your clientele, you have decided to provide an additional information sheet that will specifically state the amount of time you will take to fix the issue. Which of the following will you use to calculate the average amount of time required to repair the faulty device?a. CARPb. MTBFc. LACPd. MTTR
MTTR
Which of the following planes is made up of the physical or virtual devices that receive and send network messages on their way to their destinations?a. the management planeb. the control planec. the application planed. the infrastructure plane
The infrastructure plane
which of the following switches can be configured via a command line interface or a web-based management GUI?a. spine switchesb. an unmanaged switchc. leaf switchesd. a managed switch
A managed switch
You have been working as the network administrator for JP Steels. In order to cut down on operating costs, you plan to install a firewall’s OS in a VM on an inexpensive server, instead of purchasing an expensive hardware firewall to protect a LAN. Hence, you no longer require a firewall that runs on its own OS. Which of the following firewalls will you purchase in this scenario?a. a Fortinet firewall deviceb. a firewall device by Palo Alto Networksc. Barracuda’s Cloudgen firewall deviced. a Cisco firewall
Barracuda’s cloudgen firewall device
Which of the following terms refers to the technique of grouping redundant resources such as servers so they appear as a single device to the rest of the network?a. Automatic failoverb. load balancingc. use of hot-swappable partsd. clustering
Automatic failover
Which of the following network technologies uses a transport layer protocol that runs on top of TCP to allow fast transmissions over LANs, WANs, and the Internet?a. IBb. FCc. iSCSId. FCoE
iSCSI
As a network administrator of your company, you have decided to implement redundant connections between network devices to solve problems like network bottlenecks. You have decided to implement this change so that multiple network interfaces and ports can act as one logical interface and focus on increasing total throughput and better load balancing. Which of the following will you use to implement this change in your Windows device? a. clusteringb. load balancing c. NIC teamingd. Port aggregation
NIC teaming
Which of the following will help evenly distribute traffic to each device in a cluster so every device carries a portion of the load?a. redundancyb. a load balancerc. an SDN controllerd. CARP
A load balancer
Krypton Spares and Parts is an MNC dealing in motorcycle spare parts. The administration department of the company has constantly been complaining of severe network issues, and you have been hired to fix the issues. On inspection, it has come to your notice that these network fluctuations are primarily because of flooding attacks from broadcast and multicast traffic. Which of the following do you plan on using to fix this issue?a. A BPDU filterb. A BPDU guardc. a root guardd. storm control
Storm Control
In which of the following modes will a vNIC access a physical network using the host machine’s NIC? a. NAT modeb. host-only modec. isolation moded. bridged mode
Bridged mode
James has been appointed as the service manager in one of the outlets for Grason Communication, which sells switches and routers.
