Refer to the exhibit. The switches are connected via a Cat5 Ethernet cable that is tested successfully. The interfaces are configured as access ports and are both in a down status. What is the cause of the issue?
Answer: A
In speed mismatch, the link simply won't come up. In contrast to this, in duplex mismatch, the link will come up, but with poor performance.

Which two IP addressing schemes provide internet access to users on the network while preserving the public IPv4 address space? (Choose two.)
Answer: AB
Port Address Translation (PAT) is an extension of Network Address Translation (NAT) that permits multiple devices on a LAN to be mapped to a single public IP address to conserve IP addresses.

The address block 192.168.32.0/24 must be subnetted into smaller networks. The engineer must meet these requirements: ✑ Create 8 new subnets. ✑ Each subnet must accommodate 30 hosts. ✑ Interface VLAN 10 must use the last usable IP in the first new subnet. ✑ A Layer 3 interface is used. Which configuration must be applied to the interface?
Answer: C
C is correct. Requirement is 8 networks with 30 hosts 255.255.255.0 = 11111111.11111111.11111111.00000000 8 networks = 1111 with increment of 16 which is less host number than require. 30 hosts = 11100000 with increment of 32 255.255.255.224 or 11111111.11111111.11111111.11100000 8 networks for /27 are 0,32,64,96,128,160,192,224

DRAG DROP - Drag and drop the TCP or UDP details from the left onto their corresponding protocols on the right. Select and Place:
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
The provided answer is correct. UDP provides 'best effort' not TCP. UDP provides a best-effort datagram delivery service. This mechanism is best-effort because the underlying IP network does its best to deliver the datagram, but does not guarantee that the datagrams are delivered at the destination.

What are two reasons to deploy private addressing on a network? (Choose two.)
Answer: BC
A makes no sense as you could subnet public addresses into an organized hierarchy as well if you had reserved ipv4 addresses. As ipv4 addresses cost money it definitely will reduce the cost of maintaining your network.

DRAG DROP - Drag and drop the IPv6 DNS record types from the left onto the description on the right. Select and Place:
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
AAAA: Stands for "Address Record", it maps a hostname to a IPv6 address. CNAME: Stands for "Canonical Name", it is used to alias one name to another. For example, www.example.com can be an alias to example.com. NS: Stands for "Name Server", it specifies the authoritative DNS servers for a particular zone. PTR: Stands for "Pointer Record", it maps an IP address to a hostname. This is used for reverse DNS lookups. SOA: Stands for "Start of Authority", it defines the start of a DNS zone and contains information about the zone's properties such as the domain name, primary name server, and the domain administrator's email address.

Which property is shared by 10GBase-SR and 10GBase-LR interfaces?
Answer: C
10GBase-SR and 10GBase-LR are two types of 10 Gbps Ethernet standards for optical fiber communication. 10GBase-SR (Short Reach) is a 10 Gbps Ethernet standard for short-distance optical fiber communication, typically used for data center and campus network applications. It supports distances up to 300 meters over multi-mode fiber (MMF) cable. 10GBase-LR (Long Reach) is a 10 Gbps Ethernet standard for long-distance optical fiber communication, typically used for WAN (Wide Area Network) applications. It supports distances up to 10 kilometers over single-mode fiber (SMF) cable, making it well suited for high-speed inter-building or inter-data center connections.

Which network allows devices to communicate without the need to access the Internet?
Answer: B
Private Address Ranges -------------------------------------- Class A 10.0.0.0 to 10.255.255.255 Class B 172.16.0.0 to 172.32.255.255 class C 192.168.0.0 to 192.168.255.255 So 172.28.0.0/16 in the range of Private IPs in Class B. Answer is B.
