   An engineer needs to verify the external record for SMTP traffic. The engineer logged in to the server and entered the nslookup command. Which of the following commands should the engineer send before entering the DNS name?

   • Aset type=A
   • Bls -d company.mail.com
   • Cset domain=company.mail.com
   • Dset querytype=MX

   Show answer

   Answer: D

   Explanation

   To verify the external record for SMTP traffic using nslookup, the engineer should use the following command before entering the DNS name: D. set querytype=MX This command sets the query type to MX (Mail Exchange) records, which are used to specify mail servers responsible for receiving email messages on behalf of a domain. In the context of verifying the external record for SMTP traffic, setting the query type to MX will provide information about the mail servers associated with the specified domain.

   A company is reviewing ways to cut the overall cost of its IT budget. A network technician suggests removing various computer programs from the IT budget and only providing these programs on an as-needed basis. Which of the following models would meet this requirement?

   • AMultitenancy
   • BIaaS
   • CSaaS
   • DVPN

   Show answer

   Answer: C

   Explanation

   The model that would meet this requirement is C. SaaS (Software as a Service). With SaaS, a company can subscribe to software applications that are hosted by a third-party provider and accessed over the internet. This model allows a company to pay only for what they use and provides flexibility to scale up or down as needed.

4. Question 344 · 871 in bank

   Which of the following service models would MOST likely be used to replace on-premises servers with a cloud solution?

   • APaaS
   • BIaaS
   • CSaaS
   • DDisaster recovery as a Service (DRaaS)

   Show answer

   Answer: B

   Explanation

   - The most likely service model to replace on-premises servers with a cloud solution is Infrastructure as a Service (IaaS). IaaS provides computing resources, such as virtual servers, storage, and networking, over the internet. This allows organizations to move their server infrastructure to the cloud, eliminating the need for on-premises servers and hardware.

5. Question 345 · 871 in bank

   An IP address is maintained despite a failing UPS that causes a workstation to restart several times. Which of the following would allow this to occur?

   • ADHCP reservation
   • BDHCP scope
   • CName server
   • DRoot DNS server

   Show answer

   Answer: A

   Explanation

   The scenario where an IP address is maintained despite a failing UPS (Uninterruptible Power Supply) that causes a workstation to restart several times suggests the use of: A. DHCP reservation A DHCP reservation is a configuration in a DHCP server that associates a specific IP address with the MAC address of a device. This ensures that the device, in this case, the workstation, always receives the same IP address when it requests an address from the DHCP server, even if it restarts multiple times. The DHCP reservation provides consistency and helps in scenarios where maintaining a consistent IP address for a specific device is essential. Options B (DHCP scope), C (Name server), and D (Root DNS server) are not directly related to the scenario described and are not mechanisms for associating a specific IP address with a particular device.

6. Question 346 · 871 in bank

   A network administrator wants to control new router deployments via the use of application programming interfaces (APIs). This would be an example of:

   • Asoftware-defined networking.
   • Ba three-tiered architecture.
   • Ccollapsed backbone.
   • Dtop-of-rack switching.

   Show answer

   Answer: A

   Explanation

   A network administrator wanting to control new router deployments via the use of application programming interfaces (APIs) would be an example of: A. software-defined networking. Software-defined networking (SDN) involves the use of APIs to control and manage network devices programmatically. SDN separates the control plane from the data plane, allowing administrators to manage network devices and their behavior through software applications using APIs. It provides flexibility, automation, and programmability in network management. Options B, C, and D are not directly related to the use of APIs for controlling router deployments and are associated with different networking concepts.

   A technician is equipped with a tablet, a smartphone, and a laptop to troubleshoot a switch with the help of support over the phone. However, the technician is having issues interconnecting all these tools in troubleshooting the switch. Which of the following should the technician use to gain connectivity?

   • APAN
   • BWAN
   • CLAN
   • DMAN

   Show answer

   Answer: A

   Explanation

   The devil is in the details, stupid question. It says the technician is equipped with 3 things that he will use to troubleshoot the switch. Tools = his 3 devices Problem requiring troubleshooting = switch It says he's having trouble interconnecting his tools, which would require a PAN. That's my take at least. I find that with these questions you need to take your time reading the English they use more than anything

   Users within a corporate network need to connect to the internet, but corporate network policy does not allow direct connections. Which of the following is MOST likely to be used?

   • AProxy server
   • BVPN client
   • CBridge
   • DVLAN

   Show answer

   Answer: A

   Explanation

   A proxy server is a system or router that provides a gateway between users and the internet. Therefore, it helps prevent cyber attackers from entering a private network. It is a server, referred to as an “intermediary” because it goes between end-users and the web pages they visit online. Source: Fortinet website.

   A network is secured and is only accessible via TLS and IPSec VPNs. Which of the following would need to be present to allow a user to access network resources on a laptop without logging in to the VPN application?

   • ASite-to-site
   • BSecure Shell
   • CIn-band management
   • DRemote desktop connection

   Show answer

   Answer: A

   Explanation

   I think it's A. My research found this. "Site-to-site VPN (virtual private network) is a type of VPN that keeps data encrypted between two networks without needing credentials or client apps on devices using it." Site to site uses both IPsec and TLS. In fact, they can be used together.
