Which of the following describes the BEST device to configure as a DHCP relay?
Answer: B
A layer 3 switch would have received my vote but not a Data Link layer 2 switch. Routers, IP assignments (DHCP) occur at network layer.

Which of the following compromises Internet-connected devices and makes them vulnerable to becoming part of a botnet? (Choose two.)
Answer: BE
Googling the definition of compromise gives you the following: * bring into disrepute or danger by indiscreet, foolish, or reckless behavior. "situations in which his troops could be compromised." * cause to become vulnerable or function less effectively. "yo-yo dieting can compromise your immune system." By that definition, using default credentials would be considered "compromising" a device as such actions (or lack thereof) would make the said device vulnerable to things such as a dictionary attack and, therefore, to becoming part of a botnet.

A network administrator is planning a WLAN for a soccer stadium and was advised to use MU-MIMO to improve connection performance in high-density areas. The project requires compatibility with clients connecting using 2.4GHz or 5GHz frequencies. Which of the following would be the BEST wireless standard for this project?
Answer: B
802.11a - 5GHZ 802.11b - 2.4GHZ 802.11g - 2.4GHZ 802.11n - 2.4/5GHZ MIMO 802.11ac - 5GHZ MU-MIMO 802.11ax - 2.4/5/6GHZ MU-MIMO

An organization purchased an allocation of public IPv4 addresses. Instead of receiving the network address and subnet mask, the purchase paperwork indicates the allocation is a /28. This type of notation is referred to as:
Answer: A
A: Classless Inter-Domain Routing (CIDR) is a group of IP addresses that are allocated to the customer when they demand a fixed number of IP addresses. In CIDR there is no wastage of IP addresses as compared to classful addressing because only the numbers of IP addresses that are demanded by the customer are allocated to the customer. The group of IP addresses is called Block in Classless Inter - Domain (CIDR). CIDR follows CIDR notation or Slash notation. The representation of CIDR notation is x.y.z.w /n the x.y.z.w is IP address and n is called mask or number of bits that are used in network id. https://www.tutorialspoint.com/what-is-cidr-and-how-it-works

A network technician is reviewing a document that specifies how to handle access to company resources, such as the Internet and printers, when devices are not part of the company's assets. Which of the following agreements would a user be required to accept before using the company's resources?
Answer: C
This part would be AUP as it's the companies resources. A network technician is reviewing a document that specifies how to handle access to company resources, such as the Internet and printers And this part of the first sentence would be BYOD , when devices are not part of the company's assets. However neither of the two above parts are a question. It's a statement of what the technician is doing. The second sentence contains the actual question being asked. Which of the following agreements would a user be required to accept before using the company's resources? Since the question is only asking what they need to accept to use the companies resources this would be strictly AUP. If they had asked what the user would need to accept to use their devices for company business it would then be BYOD.

Which of the following records can be used to track the number of changes on a DNS zone?
Answer: A
SOA The DNS ‘start of authority’ (SOA) record stores important information about a domain or zone such as the email address of the administrator, when the domain was last updated, and how long the server should wait between refreshes. All DNS zones need an SOA record in order to conform to IETF standards. SOA records are also important for zone transfers.

A network administrator is trying to add network redundancy for the server farm. Which of the following can the network administrator configure to BEST provide this capability?
Answer: A
A. Network redundancy refers to having multiple systems or components in place that can perform the same functions in case of failure or downtime, ensuring that the network remains available and accessible. VRRP (Virtual Router Redundancy Protocol) is a protocol that provides redundancy for IP networks by allowing multiple routers to share a single virtual IP address, providing automatic failover if one of the routers fails. In contrast, a UPS provides backup power for the servers in the event of a power outage, but it does not provide network redundancy. The goal of a UPS is to keep the servers running until they can be safely shut down in case of a power failure, but it does not provide any backup or redundancy for the network. RPO (Recovery Point Objective) refers to the maximum acceptable amount of data loss that is tolerable in the event of a disaster or data loss, and is a term commonly used in the context of backup and disaster recovery planning.

A network administrator is adding a new switch to the network. Which of the following network hardening techniques would be BEST to use once the switch is in production?
Answer: A
You wouldn't want to disable port security, as that is the feature on switches that block unauthorized connections to switches based on the connecting device's MAC address. Answers B and C also decrease security. Answer B would disable SSH, the protocol used to securely console into a remote device. Answer C is essentially port security, but it is not really security because anyone can spoof MAC addresses.

A new cabling certification is being requested every time a network technician rebuilds one end of a Cat 6 (vendor-certified) cable to create a crossover connection that is used to connect switches. Which of the following would address this issue by allowing the use of the original cable?
Answer: D
D. MDIX (Media Dependent Interface Crossover) would address this issue by allowing the use of the original cable for connecting switches. MDIX automatically detects and compensates for cable crossover, eliminating the need for a crossover cable.
