Question 1

Emily has just migrated the email from the company's on-premises data center to a cloud service provider. She has modified the appropriate A records, but e-mail isn't being delivered to the new servers. Which of the following records does she still need to modify?

Accepted Answer

MX (Mail Exchange) records are specifically used to specify the mail servers responsible for receiving email on behalf of a domain. Since Emily has migrated the email services to a new provider, updating the MX records is necessary to direct email traffic to the new servers. A records alone are not sufficient for this purpose.

Question 2

Wanda is trying to determine which routes packets are traveling over when accessing the company's chosen cloud service provider. Which of the following Windows tools can help her discover that information?

Accepted Answer

Tracert is a command-line utility in Windows that allows users to determine the route packets take to reach a specific destination by displaying the path and measuring transit delays of packets across an Internet Protocol (IP) network.

Question 3

A year ago Yvette configured two servers on separate VLANs. She still needs them to remain on separate VLANs, but now has a need for them to be able to send certain communications to each other over a certain port. Which of the following will be necessary for her to do?

Accepted Answer

Creating a route between the two VLANs allows them to communicate with each other over specified ports while still maintaining their separate VLAN configurations. This is achieved by configuring inter-VLAN routing, typically on a layer 3 switch or router, which directs traffic between the VLANs based on the routing rules set up.

Question 4

Isabel is troubleshooting a DNS issue on one of her Windows servers. Which of the following commands might let her look up the DNS records so she can track down where the problem might be?

Accepted Answer

The "nslookup" command is used to query DNS records and can help troubleshoot DNS issues on Windows servers.

Question 5

Adrienne wants to be able to analyze the traffic coming into a Linux server's network interface. Which of the following command line utilities will allow her to see this information?

Accepted Answer

tcpdump is a command-line utility that allows users to capture and analyze network traffic passing through a system's network interface. It is widely used for network troubleshooting and analysis.

Question 6

Ursula is working on a Linux system and wants to determine which routers a packet will traverse when a packet is sent to a certain destination. Which of the following command line tools can she use to find that information?

Accepted Answer

The correct command line tool for determining the routers a packet traverses on a Linux system is "traceroute". This tool maps the journey that a packet takes from the source to the destination by sending packets with incremental TTL (Time To Live) values, thereby identifying each router it passes through until it reaches the destination.

Question 7

Uma has been analyzing the performance and baselines from her virtual machines that are on a cloud service provider's platform. She sees that they do not appear to be performing up to the standards that her cloud service provider guarantees. Which of the following documents outlines the standards that they are guaranteeing?

Accepted Answer

The Service Level Agreement (SLA) outlines the standards and guarantees that a cloud service provider offers to its clients, including performance metrics and uptime commitments.

Question 8

Olivia manages a group of Windows and Linux servers. She knows there is a command that she can use to view currently open network connections that works on both platforms. Which of the following commands will she most likely use?

Accepted Answer

The command "netstat" is available on both Windows and Linux operating systems and is used to display active network connections, routing tables, and a number of network interface statistics. It is a common tool for network diagnostics and troubleshooting on both platforms.

Question 9

Yolanda wants to see a list of MAC addresses that one of her servers has been communicating with. Which of the following command line tools will display that information?

Accepted Answer

The arp command is used to display and modify the IP-to-Physical address translation tables used by the Address Resolution Protocol (ARP). It can show the MAC addresses of devices that a server has been communicating with on the local network.

Question 11

Zoie is working on a Windows server that has two network interfaces. One is assigned an IP address by a DHCP server while the other is a static IP address. She wants to see what the current dynamic IP address is. Which of the following command line utilities can she use to view that information?

Accepted Answer

The correct command line utility to view IP address information on a Windows server is "ipconfig". This utility allows users to see the configurations of their network interfaces, including dynamic (DHCP) and static IP addresses.

Question 12

She has decided to start deploying copies of that server to various regions and wants to direct traffic to the site that is closest to each user. Which of the following technologies could she use to do this?

Accepted Answer

GSLB (Global Server Load Balancing) is the technology designed to distribute traffic across multiple servers located in different geographical locations, directing users to the closest or best-performing server.

Question 13

Victoria is trying to determine whether one of the new servers she set up on the cloud service provider is reachable and online from her current workstation. Which of the following tools is she most likely trying to use?

Accepted Answer

Ping is a network utility that is used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer.
