Question 3
Drag and drop the descriptions of file-transfer protocols from the left onto the correct protocols on the right.
Correct answer: To work with this question, an Exam Simulator is required.
Question 4
A frame that enters a switch fails the Frame Check Sequence. Which two interface counters are incremented? (Choose two.)
  1. input errors
  2. frame
  3. giants
  4. CRC
  5. runts
Correct answer: AD
Explanation:
Whenever the physical transmission has problems, the receiving device might receive a frame whose bits have changed values. These frames do not pass the error detection logic as implemented in the FCS field in the Ethernet trailer. The receiving device discards the frame and counts it as some kind of input error. Cisco switches list this error as a CRC error. Cyclic redundancy check (CRC) is a term related to how the FCS math detects an error.input errors includes runts, giants, no buffer, CRC, frame, overrun, and ignored The counts.show interface s0/0/0The output below show the interface counters with the command:

Question 5
Drag and drop the IPv4 network subnets from the left onto the correct usable host ranges on the right.
Correct answer: To work with this question, an Exam Simulator is required.
Explanation:
This subnet question requires us to grasp how to subnet very well. To quickly find out the subnet range, we have to find out the increment and the network address of each subnet. Let's take an example with the subnet 172.28.228.144/18:From the /18 (= 1100 0000 in the 3rd octet), we find out the increment is 64. Therefore the network address of this subnet must be the greatest multiple of the increment but not greater than the value in the 3rd octet (228). We can find out the 3rd octet of the network address is 192 (because 192 = 64 * 3 and 192 < 228) - > The network address is 172.28.192.0. So the first usable host should be 172.28.192.1 and it matches with the 5th answer on the right. In this case we don't need to calculate the broadcast address because we found the correct answer. Let's take another example with subnet 172.28.228.144/23 -> The increment is 2 (as /23 = 1111 1110 in 3rd octet) -> The 3rd octet of the network address is 228 (because 228 is the multiply of 2 and equal to the 3rd octet) -> The network address is 172.28.228.0 -> The first usable host is 172.28.228.1. It is not necessary but if we want to find out the broadcast address of this subnet, we can find out the next network address, which is 172.28.(228 + the increment number).0 or 172.28.230.0 then reduce 1 bit -> 172.28.229.255 is the broadcast address of our subnet. Therefore the last usable host is 172.28.229.254.

Question 6
How do TCP and UDP differ in the way that they establish a connection between two endpoints?
  1. TCP uses the three-way handshake, and UDP does not guarantee message delivery.
  2. TCP uses synchronization packets, and UDP uses acknowledgment packets.
  3. UDP provides reliable message transfer, and TCP is a connectionless protocol.
  4. UDP uses SYN, SYN ACK, and FIN bits in the frame header while TCP uses SYN, SYN ACK, and ACK bits.
Correct answer: A
Question 7
Which 802.11 frame type is Association Response?
  1. management
  2. protected frame
  3. action
  4. control
Correct answer: A
Explanation:
There are three main types of 802.11 frames: the Data Frame, the Management Frame and the Control Frame. Association Response belongs to Management Frame. Association response is sent in response to an association request.Reference:https://en.wikipedia.org/wiki/802.11_Frame_Types

Question 8
In which way does a spine-and-leaf architecture allow for scalability in a network when additional access ports are required?
  1. A spine switch and a leaf switch can be added with redundant connections between them.
  2. A spine switch can be added with at least 40 GB uplinks.
  3. A leaf switch can be added with connections to every spine switch.
  4. A leaf switch can be added with a single connection to a core spine switch.
Correct answer: C
Explanation:
Spine-leaf architecture is typically deployed as two layers: spines (such as an aggregation layer), and leaves (such as an access layer). Spine-leaf topologies provide high-bandwidth, low-latency, nonblocking server-to-server connectivity. Leaf (aggregation) switches are what provide devices access to the fabric (the network of spine and leaf switches) and are typically deployed at the top of the rack. Generally, devices connect to the leaf switches. Devices can include servers, Layer 4-7 services (firewalls and load balancers), and WAN or Internet routers. Leaf switches do not connect to other leaf switches. In spine-and-leaf architecture, every leaf should connect to every spine in a full mesh. Spine (aggregation) switches are used to connect to all leaf switches and are typically deployed at the end or middle of the row. Spine switches do not connect to other spine switches.

Question 9
What identifies the functionality of virtual machines?
  1. The hypervisor communicates on Layer 3 without the need for additional resources.
  2. Each hypervisor supports a single virtual machine and a single software switch.
  3. The hypervisor virtualizes physical components including CPU, memory, and storage.
  4. Virtualized servers run efficiently when physically connected to a switch that is separate from the hypervisor.
Correct answer: C
Question 10
Which command automatically generates an IPv6 address from a specified IPv6 prefix and MAC address of an interface?
  1. ipv6 address dhcp
  2. ipv6 address 2001:DB8:5:112::/64 eui-64
  3. ipv6 address autoconfig
  4. ipv6 address 2001:DB8:5:112::2/64 link-local
Correct answer: C
Explanation:
ipv6 address autoconfig command causes the device to perform IPv6 stateless The address auto-configuration to discover prefixes on the link and then to add the EUI-64 based addresses to the interface. Addresses are configured depending on the prefixes received in Router Advertisement (RA) messages. The device will listen for RA messages which are transmitted periodically from the router (DHCP Server). This RA message allows a host to create a global IPv6 address from:Its interface identifier (EUI-64 address)Link Prefix (obtained via RA)Note: Global address is the combination of Link Prefix and EUI-64 address
