NEW QUESTION # 195
Which of the following protocol types describes secure communication on port 443?
- A. UDP
- B. IP
- C. TCP
- D. ICMP
Answer: C
Explanation:
TCP is the protocol type that describes secure communication on port 443. TCP (Transmission Control Protocol) is a connection-oriented protocol that provides reliable and ordered delivery of data packets over an IP network. TCP uses port numbers to identify different applications or services on a device. Port 443 is the default port for HTTPS (Hypertext Transfer Protocol Secure), which is an extension of HTTP that uses SSL (Secure Sockets Layer) or TLS (Transport Layer Security) encryption to protect data in transit between a web server and a web browser.

NEW QUESTION # 196
A user is tricked into providing log-in credentials to an attacker over the telephone. Which of the following attacks is this an example of?
- A. Dumpster diving
- B. Shoulder surfing
- C. Phishing
- D. Tailgating
Answer: C
Explanation:
Explanation
Phishing is a type of social engineering attack that uses email, phone, SMS, or other forms of personal communication to trick users into revealing sensitive information, such as log-in credentials, to an attacker. In this case, the user was deceived by a phone call that pretended to be from a legitimate source and asked for their log-in details.
NEW QUESTION # 197
A network technician is performing tests on a potentially faulty network card that is installed in a server. Which of the following addresses will MOST likely be used during traffic diagnostic tests?
- A. 127.0.0.1
- B. 192.168.0.1
- C. 10.10.10.10
- D. 255.255.255.0
Answer: A
Explanation:
The address 127.0.0.1 is a special IP address that is used to refer to the local host or the computer itself12.
This address is also known as the loopback address, because it loops back to the same device without going through any network devices12.
A network technician can use this address to perform traffic diagnostic tests on a potentially faulty network card, by sending and receiving packets to and from the same device12.
This way, the technician can check if the network card is functioning properly, without involving any external factors such as network congestion, firewall rules, or routing issues12.
The address 10.10.10.10 (A) is a private IP address that is used for internal network communication, but it is not a loopback address12.
The address 192.168.0.1 is another private IP address that is often used as the default gateway for home routers, but it is also not a loopback address12.
The address 255.255.255.0 (D) is a subnet mask that is used to define the network and host portions of an IP address, but it is not an IP address itself12. Reference:

NEW QUESTION # 198
Which of the following technologies would MOST likely De used to prevent the loss of connection between a virtual server and network storage devices?
- A. Multipathing
- B. VRRP
- C. NIC teaming
- D. Port aggregation
Answer: C
Explanation:
NIC teaming is a technology that allows multiple network interface cards (NICs) to work together as a single logical interface, providing redundancy and load balancing. This can prevent the loss of connection between a virtual server and network storage devices if one of the NICs fails or becomes disconnected. References:

NEW QUESTION # 200
Which of the following DNS records works as an alias to another record?
- A. SOA
- B. MX
- C. CNAME
- D. AAAA
Answer: C
Explanation:
AAAA record is used to find the IP address of a computer connected to the internet from a name.
CNAME record is a type of DNS record that maps an alias name to a true or canonical domain name.
MX record specifies the mail server responsible for accepting email messages on behalf of a domain name.
SOA record is a type of resource record in the DNS containing administrative information about the zone.
NEW QUESTION # 201
Which of the following is most closely associated with the management plane?
- A. File operations
- B. Routing table
- C. Console port
- D. Current configuration
Answer: C
NEW QUESTION # 202
Which of the following provides redundancy on a file server to ensure the server is still connected to a LAN even in the event of a port failure on a switch?
- A. RAID array
- B. PDUs
- C. NIC teaming
- D. Load balancer
Answer: C
Explanation:
Explanation
NIC teaming, also known as network interface card teaming or link aggregation, allows multiple network interface cards to be grouped together to provide redundancy and increased throughput. In the event of a port failure on a switch, NIC teaming ensures that the file server remains connected to the LAN by automatically switching to another network interface card.

NEW QUESTION # 203
An administrator needs to connect two laptops directly to each other using 802.11ac but does not have an AP available. Which of the following describes this configuration?
- A. Extended service set
- B. MU-MIMO
- C. Basic service set

NEW QUESTION # 204
A network administrator is trying to create a subnet, which is the most efficient size possible, for 31 laptops.
Which of the following network subnets would be best in this situation?
- A. 10.10.10.0/25
- B. 10.10.10.0/26
- C. 10.10.10.0/27
- D. 10.10.10.0/24
Answer: C
Explanation:
A /27 subnet mask has 32 IP addresses, of which 30 are usable for hosts. This is the smallest subnet that can accommodate 31 laptops, as the other options have either too few or too many IP addresses. A /27 subnet mask is equivalent to 255.255.255.224 in decimal notation, and has a wildcard mask of 0.0.0.31. The network address is 10.10.10.0, and the broadcast address is 10.10.10.31. The usable host range is 10.10.10.1 to
10.10.10.30.

NEW QUESTION # 211
A large number of PCs are obtaining an APIPA IP address, and a number of new computers were added to the network. Which of the following is MOST likely causing the PCs to obtain an APIPA address?
- A. Network collision
- B. Rogue DHCP server
- C. DHCP scope exhaustion
- D. Incorrect DNS settings
Answer: C
Explanation:
Explanation
DHCP scope exhaustion means that there are no more available IP addresses in the DHCP server's pool of addresses to assign to new devices on the network. When this happens, the devices will use APIPA (Automatic Private IP Addressing) to self-configure an IP address in the range of 169.254.0.1 to 169.254.255.2541. These addresses are not routable and can only communicate with other devices on the same local network.
A rogue DHCP server (A) is an unauthorized DHCP server that can cause IP address conflicts or security issues by assigning IP addresses to devices on the network. A network collision (B) is a situation where two or more devices try to send data on the same network segment at the same time, causing interference and data loss. Incorrect DNS settings can prevent devices from resolving domain names to IP addresses, but they do not affect the DHCP process.
NEW QUESTION # 212
Which of the following, in addition to a password, can be asked of a user for MFA?
- A. Mother's maiden name
- B. PIN
- C. Favorite color
- D. Hard token
Answer: B
Explanation:
Explanation
MFA stands for Multi-Factor Authentication, which is a method of verifying the identity of a user by requiring two or more pieces of evidence that belong to different categories: something the user knows, something the user has, or something the user is. A password is something the user knows, and it is usually combined with another factor such as a PIN (Personal Identification Number) or a hard token (a physical device that generates a one-time code) that the user has. A favorite color or a mother's maiden name are not suitable for MFA, as they are also something the user knows and can be easily guessed or compromised.
