CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 711:

  Which of the following describes the difference between a DNS server and a DHCP server?

  A. DNS is used for address translation, while DHCP is used for IP address assignment.

  B. DNS is used for routing, while DHCP is used for name resolution.

  C. DNS only assigns private IP addresses, while DHCP only assigns public IP addresses.

  D. DNS is used to route traffic between networks, while DHCP is used to allocate subnets.

  Correct Answer: A

  Explanation: DNS stands for Domain Name System, and it is a network service that translates human-readable names (such as www.google.com) into numerical IP addresses (such as 172.217.14.206) that identify the location of the web servers on the internet. DNS also allows reverse lookup, which means finding the domain name associated with a given IP address. DNS servers are responsible for maintaining a database of domain names and their corresponding IP addresses, and responding to queries from clients who want to resolve a name to an address or vice versa12. DHCP stands for Dynamic Host Configuration Protocol, and it is a network service that automatically assigns IP addresses and other network configuration parameters (such as subnet mask, default gateway, DNS server, etc.) to devices that join a network. DHCP servers are responsible for managing a pool of IP addresses and leasing them to clients for a specified duration. DHCP servers also renew or release the IP addresses when the lease expires or the client disconnects from the network34. The difference between DNS and DHCP is that DNS is used for address translation, which means converting domain names to IP addresses and vice versa, while DHCP is used for IP address assignment, which means providing IP addresses and other network settings to devices that need to communicate on a network.

• Question 712:

  Which of the following network devices should a technician install in order to isolate voice traffic on the network?

  A. Network tap

  B. Managed switch

  C. Hub

  D. DSL filter

  Correct Answer: B

  Explanation: A managed switch is a network device that can be configured to create VLANs (Virtual Local Area Networks), which are logical segments of a network that isolate traffic based on criteria such as function, security, or quality of service. A VLAN can be used to isolate voice traffic on the network, which can improve the performance and security of voice over IP (VoIP) applications. A network tap, a hub, and a DSL filter are not capable of creating VLANs. Reference: [CompTIA A+ Core 1 (220-1101) Certification Study Guide], page 32.

• Question 715:

  Which of the following cloud models allows an organization to retain data on site as well as in the cloud?

  A. Public

  B. Community

  C. Hybrid

  D. Private

  Correct Answer: C

  Explanation: The correct answer is C. Hybrid.

  A hybrid cloud model is a combination of two or more different cloud models, such as public, private, community, or on-premises. A hybrid cloud model allows an organization to retain data on site as well as in the cloud, depending on the security and performance requirements of the data. A hybrid cloud model can also provide flexibility, scalability, and cost-efficiency for the organization12. A public cloud model is a cloud service that is available to anyone over the internet. A public cloud model does not allow an organization to retain data on site, as the data is stored and managed by a third-party provider. A public cloud model can offer lower costs, higher availability, and easier access, but it may have less security and control over the data12. A community cloud model is a cloud service that is shared by a group of organizations that have similar needs or goals. A community cloud model does not allow an organization to retain data on site, as the data is stored and managed by a third-party provider or one of the participating organizations. A community cloud model can offer higher security, privacy, and compliance, but it may have higher costs and lower availability than a public cloud model12. A private cloud model is a cloud service that is exclusively used by a single organization. A private cloud model can allow an organization to retain data on site or in the cloud, depending on the configuration of the private cloud. A private cloud model can offer higher security, control, and customization, but it may have higher costs and lower scalability than a public cloud model12.

• Question 716:

  After an IT department implements SSL redirection, users report being unable to access a random number generator opened within a web browser.

  Which of the following should a technician do first to troubleshoot this issue?

  A. Ensure that the computer supports secure socket communication.

  B. Report the affected user accounts to the IT department.

  C. Reset the web browser cache.

  D. Check to see whether the website is HTTPS enabled.

  Correct Answer: D

  Explanation: The first step to troubleshoot this issue is to check if the website that hosts the random number generator is HTTPS enabled. This means that the website supports secure communication using SSL certificates and encryption. If the website is not HTTPS enabled, it may not be compatible with the SSL redirection implemented by the IT department. SSL redirection is a technique that automatically redirects HTTP requests to HTTPS, ensuring that the data exchanged between the web browser and the website is protected. However, some websites may not have SSL certificates or may have expired or invalid ones, which can cause errors or warnings when trying to access them via HTTPS. Therefore, the technician should check the website's URL and see if it starts with https:// or http://. If it is the latter, the technician should try to manually change it to https:// and see if the website loads correctly. If it does not, the technician should contact the website owner or administrator and ask them to enable HTTPS or update their SSL certificates.

• Question 718:

  An IT technician is troubleshooting an issue with connecting a new laptop to a company's wireless network. Which of the following diagnostic steps should the technician take first?

  A. Review the network settings in the OS.

  B. Install the latest firmware updates on the WAPs.

  C. Increase the signal strength of the router.

  D. Reset the router and reconfigure the wireless settings.

  Correct Answer: A

  Explanation: The first step in troubleshooting any network issue is to identify the problem and gather information from the user and the device. Reviewing the network settings in the OS can help the technician verify if the laptop is configured correctly to connect to the wireless network, such as the SSID, security type, password, IP address, DNS server, etc. This can also help the technician rule out any software or driver issues that might prevent the laptop from connecting to the network. This is a logical and simple step that can be done before attempting any other actions that might affect the network infrastructure or other devices.

• Question 719:

  A systems administrator needs to set up a multifunction printer for the legal department. The legal department deals with sensitive documents and requires a secure method of releasing print jobs. Which of the following should the systems administrator configure to meet the department's security requirements?

  A. SMB settings

  B. User authentication

  C. Audit logging

  D. Wired connection

  Correct Answer: B

  Explanation: This option requires the user to enter a PIN code or swipe a smart card before the printer releases their print job. This way, the user can verify their identity and ensure that no one else can access their sensitive documents. The other options are not as secure or effective as user authentication. SMB settings are used to share files and printers over a network, but they do not provide a secure method of releasing print jobs. Audit logging records the details of each print job, but it does not prevent unauthorized access to the printed documents. Wired connection reduces the risk of wireless interference or hacking, but it does not guarantee that the print jobs are only retrieved by the intended recipient.

• Question 720:

  Isolating email attachments in a safe place until the attachments can be scanned for malware is defined as:

  A. an approve listing.

  B. a screened subnet.

  C. cross-platform virtualization.

  D. sandboxing.

  Correct Answer: D

  Explanation: The correct answer is D. Sandboxing.

  Sandboxing is a security technique that isolates email attachments in a safe place until the attachments can be scanned for malware. A sandbox is a virtual environment that mimics the operating system and applications of the user, but prevents any changes or damage to the actual system. A sandbox can also monitor the behavior and activity of the attachments and detect any malicious code or actions12. An approve listing is a security technique that allows only trusted or authorized email senders or domains to be received by the user. An approve listing can help reduce spam and phishing emails, but it does not scan or isolate email attachments for malware3. A screened subnet is a security technique that creates a buffer zone between the internal network and the internet. A screened subnet uses firewalls and routers to filter and control the traffic that enters and exits the network. A screened subnet can help protect the network from external attacks, but it does not scan or isolate email attachments for malware. Cross-platform virtualization is a technology that allows running multiple operating systems and applications on the same physical machine. Cross-platform virtualization can help improve efficiency, flexibility, and compatibility, but it does not scan or isolate email attachments for malware.
