Which of the following is typical of software licensing in the cloud?
A. Per socket
B. Perpetual
C. Subscription-based
D. Site-based
Correct Answer: C
Cloud software licensing refers to the process of managing and storing software licenses in the cloud. The benefits of cloud software licensing models are vast. The main and most attractive benefit has to do with the ease of use for software vendors and the ability to provide customizable cloud software license management based on customer needs and desires1. Cloud-based licensing gives software developers and vendors the opportunity to deliver software easily and quickly and gives customers full control over their licenses, their analytics, and more1. Cloud based licensing gives software sellers the ability to add subscription models to their roster of services1. Subscription models are one of the most popular forms of licensing today1. Users sign up for a subscription (often based on various options and levels of use, features, etc.) and receive their licenses instantly1.

Question 242:
A server administrator wants to run a performance monitor for optimal system utilization. Which of the following metrics can the administrator use for monitoring? (Choose two.)
A. Memory
B. Page file
C. Services
D. Application
E. CPU
F. Heartbeat
Correct Answer: AE
Memory and CPU are two metrics that can be used for monitoring system utilization. Memory refers to the amount of RAM that is available and used by the system and its processes. CPU refers to the percentage of processor time that is consumed by the system and its processes. Both memory and CPU can affect the performance and responsiveness of the system and its applications. Monitoring memory and CPU can help identify bottlenecks, resource contention, memory leaks, high load, etc.
Question 243:
After configuring IP networking on a newly commissioned server, a server administrator installs a straight- through network cable from the patch panel to the switch. The administrator then returns to the server to test network connectivity using the ping command. The partial output of the ping and ipconfig commands are displayed below:
The administrator returns to the switch and notices an amber link light on the port where the server is connected. Which of the following is the MOST likely reason for the lack of network connectivity?
A. Network port security
B. An improper VLAN configuration
C. A misconfigured DHCP server
D. A misconfigured NIC on the server
Correct Answer: D
Some devices, such as network switches, use colors to indicate performance information rather than status information. For example, a network switch may display a green LED on a port if the connection is operating at 1 Gbps but an amber
LED if the port is operating at 100 Mbps. Check the device's documentation to interpret the colors correctly.

Question 244:
A snapshot is a feature that can be used in hypervisors to:
A. roll back firmware updates.
B. restore to a previous version.
C. roll back application drivers.
D. perform a backup restore.
Correct Answer: B
Answer is B. The one of the differences between a storage snapshot and a backup is that the snapshot is stored at the same location as the original data. Therefore, it depends entirely on the reliability of the source. This means that in case of a disaster or damage to the source data, the storage snapshot will be lost or inaccessible. There is no way to restore if the source gets lost. In addition, snapshots on their own do not have the means to check for corruption or restore capabilities.
Question 245:
A global organization keeps personnel application servers that are local to each country. However, a security audit shows these application servers are accessible from sites in other countries. Which of the following hardening techniques should the organization use to restrict access to only sites that are in the same country?
A server administrator needs to deploy five VMs, all of which must have the same type of configuration. Which of the following would be the MOST efficient way to perform this task?
A. Snapshot a VM.
B. Use a physical host.
C. Perform a P2V conversion.
D. Use a VM template.
Correct Answer: D
Deploying a virtual machine from a template creates a virtual machine that is a copy of the template. The new virtual machine has the virtual hardware, installed software, and other properties that are configured for the template.
The most efficient way to perform the task of deploying five VMs with the same type of configuration is to use a VM template. A template is a preconfigured virtual machine image that contains an operating system, applications, settings, and other components. A template can be used to create multiple identical or customized VMs quickly and easily, without having to install and configure each VM from scratch. A template can save time and ensure consistency across VMs.
The Chief Information Officer (CIO) of a datacenter is concerned that transmissions from the building can be detected from the outside. Which of the following would resolve this concern? (Choose two.)
A. RFID
B. Proximity readers
C. Signal blocking
D. Camouflage
E. Reflective glass
F. Bollards
Correct Answer: CE
The best solutions to resolve the concern of transmissions from the building being detected from outside are signal blocking and reflective glass. Signal blocking is a method of preventing or interfering with electromagnetic signals from escaping or entering a certain area. Signal blocking can be achieved by using various materials or devices that create physical barriers or generate noise or jamming signals. Signal blocking can protect data transmissions from being intercepted or eavesdropped by unauthorized parties. Reflective glass is a type of glass that has a coating or film that reflects light and heat. Reflective glass can reduce glare and solar radiation, as well as prevent visual observation from outside. Reflective glass can enhance privacy and security for datacenter operations.
Question 248:
A server administrator is configuring the IP address on a newly provisioned server in the testing environment. The network VLANs are configured as follows:
The administrator configures the IP address for the new server as follows:
1.
IP address: 192.168.1.1/24
2.
Default gateway: 192.168.10.1
A ping sent to the default gateway is not successful. Which of the following IP address/default gateway combinations should the administrator have used for the new server?
A. IP address: 192.168.10.2/24 Default gateway: 192.168.10.1
B. IP address: 192.168.1.2/24 Default gateway: 192.168.10.1
C. IP address: 192.168.10.3/24 Default gateway: 192.168.20.1
D. IP address: 192.168.10.24/24 Default gateway: 192.168.30.1
Correct Answer: A
The IP address/default gateway combination that the administrator should have used for the new server is IP address: 192.168.10.2/24 and Default gateway:
192.168.10.1. The IP address and the default gateway of a device must be in the same subnet to communicate with each other. A subnet is a logical division of a network that allows devices to share a common prefix of their IP addresses. The subnet mask determines how many bits of the IP address are used for the network prefix and how many bits are used for the host identifier. A /24 subnet mask means that the first 24 bits of the IP address are used for the network prefix and the last 8 bits are used for the host identifier. Therefore, any IP address that has the same first 24 bits as the default gateway belongs to the same subnet. In this case, the default gateway has an IP address of 192.168.10.1/24, which means that any IP address that starts with 192.168.10.x/24 belongs to the same subnet. The new server has an IP address of 192.168.1.1/24, which does not match the first 24 bits of the default gateway, so it belongs to a different subnet and cannot communicate with the default gateway. To fix this issue, the administrator should change the IP address of the new server to an unused IP address that starts with 192.168.10.x/24, such as 192.168.10.2/24.
Question 249:
A server administrator is configuring a new server that will hold large amounts of information. The server will need to be accessed by multiple users at the same time. Which of the following server roles will the administrator MOST likely need to install?
A. Messaging
B. Application
C. Print
D. Database
Correct Answer: D
Few people are expected to use the database at the same time and users don't need to customize the design of the database.
The server role that the administrator will most likely need to install for a server that will hold large amounts of information and will need to be accessed by multiple users at the same time is database. A database is a collection of structured
data that can be stored, queried, manipulated, and analyzed using various methods and tools. A database server is a server that hosts one or more databases and provides access to them over a network. A database server can handle large
amounts of information and support concurrent requests from multiple users or applications.
Which of the following would a systems administrator implement to ensure all web traffic is secure?
A. SSH
B. SSL
C. SMTP
D. PGP
Correct Answer: B
Secure Sockets Layer (SSL): SSL and its successor Transport Layer Security (TLS) enable client and server computers to establish a secure connection session and manage encryption and decryption activities.
