A technician is troubleshooting a small office network where users are reporting slow internet speeds. The network consists of a router connected to an unmanaged switch, and several workstations and printers connected to the switch. The technician notices that the cable connecting the router to the switch is a crossover cable. Both the router and the switch support Auto-MDI/X. Which of the following BEST describes the impact of using a crossover cable in this scenario?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

The crossover cable will prevent the devices from communicating because crossover cables are only used for connecting two similar devices directly

While crossover cables were traditionally used for PC-to-PC connections, Auto-MDI/X makes the cable type irrelevant. The devices will still communicate.

B

Distractor review

The crossover cable is faulty and should be replaced with a straight-through cable

There is no evidence that the cable is faulty. Both devices support Auto-MDI/X, so a crossover cable is acceptable. Slow speeds are likely due to a different cause.

C

Best answer

The crossover cable is not causing the issue; Auto-MDI/X will handle the connection properly

Auto-MDI/X automatically adjusts for cable type, so a crossover cable works correctly. The slow speeds must have another cause, such as network congestion or a bad cable run.

D

Distractor review

The crossover cable should be replaced with a straight-through cable to achieve maximum throughput

In modern networks with Auto-MDI/X, all cable types perform identically. Replacing the cable would not improve speed; the technician should investigate other issues.

Common exam trap

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Technical deep dive

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

  • Static NAT maps one inside address to one outside address.
  • PAT allows many inside hosts to share one public address using ports.
  • Inside local and inside global describe the private and translated addresses.
  • NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

  • Identify inside and outside interfaces first.
  • Check whether the scenario needs static NAT, dynamic NAT or PAT.
  • Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 1

A user reports intermittent network connectivity on a desktop computer. The technician observes that the Ethernet link light on the NIC turns off for a few seconds and then turns back on. The cable passes a wiremap test, the switch port is verified good with another device, and the NIC driver is updated. The issue occurs more frequently when the computer's case fan runs at high speed. Which of the following is the MOST likely cause?

Question 2

A workstation is unable to connect to the internet. The technician runs the 'ipconfig' command and sees the IPv4 address is 169.254.15.200 with a subnet mask of 255.255.0.0. The workstation can ping other devices on the local subnet but cannot ping the default gateway or any external addresses. Which TWO actions should the technician take to resolve this issue? (Select two.)

Question 3

A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?

Question 4

A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?

Question 5

A company has a legacy virtual machine running on a deprecated hypervisor (Hyper-V). They want to migrate this VM to a new hypervisor (VMware vSphere) hosted in a private cloud while preserving the VM's configuration, installed applications, and data. The migration must be performed with minimal downtime. Which of the following methods is MOST appropriate?

Question 6

A company hosts a critical database on a virtual machine in a public cloud. The database requires persistent storage that must be retained even if the VM is terminated. The storage must also be accessible from multiple VMs simultaneously for a future high-availability configuration. Which type of cloud storage BEST meets these requirements?

FAQ

Questions learners often ask

What does this 220-1101 question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: The crossover cable is not causing the issue; Auto-MDI/X will handle the connection properly — Auto-MDI/X (Automatic Medium Dependent Interface Cross-Over) is a feature that allows network interfaces to automatically detect and correct the type of cable (straight-through or crossover). Since both the router and switch support this feature, the crossover cable will function correctly and should not cause any issues. The slow speeds are likely due to another factor such as bandwidth saturation, a faulty cable terminator, or a device problem.
