220-1101 Practice Test 9 — 10 Questions

Question 1

A user in a small office can access shared files on the local network and can connect to the internet using a web browser when entering IP addresses directly (e.g., http://198.51.100.1) but cannot access any websites by their domain names (e.g., www.example.com). The network uses a DHCP server. Which of the following is the most likely cause of this issue?

Accepted Answer

The DNS server address is incorrect or unreachable.. The user can access resources by IP address but not by domain name, which indicates that name resolution is failing. Since the network uses DHCP, the most likely cause is that the DHCP server is providing an incorrect or unreachable DNS server address, preventing the client from resolving domain names to IP addresses.

Answer

The default gateway is configured incorrectly.

Answer

The subnet mask is set to a value that prevents Internet access.

Answer

The DHCP server has exhausted its address pool.

Question 2

A laser printer produces pages with repeated marks at regular intervals. Replacing the toner cartridge does not resolve the issue. What component is the next likely cause?

Accepted Answer

Fuser or roller assembly. Repeated marks at regular intervals on laser printer output typically indicate a mechanical issue with a rotating component, such as a fuser roller or a transfer roller. Since replacing the toner cartridge did not resolve the problem, the next likely cause is a damaged or worn fuser roller assembly, which can leave marks corresponding to its circumference as it rotates.

Answer

Low Wi-Fi signal

Answer

Incorrect DNS server

Answer

Wrong monitor resolution

Question 3

A technician is assembling a workstation for video editing. The motherboard has two DIMM slots and supports dual-channel DDR4-3200 memory. The user requests 32 GB of RAM. Which memory configuration will provide the best performance?

Accepted Answer

Two 16 GB DDR4-3200 modules. Option C is correct because it uses two identical 16 GB DDR4-3200 modules in the motherboard's two DIMM slots, enabling dual-channel memory operation. Dual-channel mode doubles the memory bandwidth compared to single-channel, which is critical for video editing workloads that involve large data transfers. The DDR4-3200 speed matches the motherboard's supported speed, ensuring optimal performance without any speed mismatches.

Answer

One 32 GB DDR4-3200 module

Answer

Two 16 GB DDR4-2666 modules

Answer

One 16 GB DDR4-3200 and one 16 GB DDR4-2666 module

Question 4

A network technician is troubleshooting a connectivity issue. Users on VLAN 10 (192.168.10.0/24) can access the internet but cannot reach a server on VLAN 20 (192.168.20.0/24) by IP address. The router's ACL allows all traffic between VLANs. The technician pings the server IP from a client on VLAN 10 and gets a request timed out. The technician then checks the routing table on the router and sees routes for both VLANs. Which of the following is the NEXT step to isolate the issue?

Accepted Answer

Perform a traceroute from the client to the server.. Option C is correct because a traceroute (using ICMP or UDP probes with increasing TTL values) will reveal the path packets take from the client to the server. Since the router's ACL permits all inter-VLAN traffic and routes exist for both VLANs, the issue likely lies beyond Layer 3 routing—possibly at a firewall, a misconfigured switch port, or a routing loop. Traceroute isolates exactly where packets are dropped, narrowing the troubleshooting scope.

Answer

Check the server's firewall settings.

Answer

Check the switch port for the server is in the correct VLAN.

Answer

Check the default gateway on the client.

Question 5

A network technician is setting up a small office with 15 workstations. The ISP provides a single public IPv4 address. The technician configures the router to assign private IP addresses (192.168.1.x) to the workstations via DHCP. Which technology allows all 15 workstations to share the single public IP address to access the internet?

Accepted Answer

NAT (Network Address Translation). NAT (Network Address Translation) allows multiple devices on a private network (like 192.168.1.x) to share a single public IPv4 address by translating the private source IP and port to the public IP and a unique port number when traffic exits the router. This enables all 15 workstations to access the internet simultaneously using the one public address provided by the ISP.

Answer

DNS (Domain Name System)

Answer

DHCP (Dynamic Host Configuration Protocol)

Answer

ARP (Address Resolution Protocol)

Question 6

A network technician is configuring a managed switch for a small office. The security requirement is that only specific authorized devices should be allowed to connect to the network via the switch ports. The technician wants to automatically learn the MAC addresses of devices as they connect and lock them to the port to prevent unauthorized devices from using the same port. Which switch feature should be configured to accomplish this?

Accepted Answer

Port security with sticky MAC. Port security with sticky MAC addresses allows the switch to dynamically learn MAC addresses from connected devices and then 'stick' them to the port, preventing any other device from using that port. This meets the requirement of automatically learning and locking authorized devices without manual MAC entry.

Answer

MAC filtering

Answer

VLAN tagging (IEEE 802.1Q)

Answer

Spanning Tree Protocol (STP)

Question 7

A network technician is configuring a small office network with one router and one managed switch. The network has two VLANs: VLAN 10 (Sales) and VLAN 20 (Engineering). Both VLANs need internet access, and inter-VLAN routing is not required. The technician configures the router's single physical interface with IP 192.168.1.1/24 and creates subinterfaces for VLAN 10 (192.168.10.1/24) and VLAN 20 (192.168.20.1/24). The switch port connecting to the router is configured as an access port in VLAN 10. Which of the following is the MOST likely result?

Accepted Answer

Only VLAN 10 can access the internet; VLAN 20 cannot.. The router's subinterfaces for VLAN 10 and VLAN 20 are configured correctly, but the switch port connecting to the router is set as an access port in VLAN 10. An access port carries traffic for only one VLAN and strips VLAN tags, so the router's subinterface for VLAN 20 never receives or sends frames tagged for VLAN 20. Consequently, only VLAN 10 can reach the router's default gateway (192.168.10.1) and access the internet, while VLAN 20 has no path to the router.

Answer

Both VLANs can access the internet.

Answer

Only VLAN 20 can access the internet; VLAN 10 cannot.

Answer

Neither VLAN can access the internet.

Question 8

A technician is deploying a new virtual machine for a development team. The host server has limited physical storage, and the VM will be used for testing software that requires a minimal amount of disk space initially. However, the development team anticipates that the VM's disk usage will grow significantly over time as more software is installed. The technician wants to allocate the required storage in a way that does not consume the entire allotment upfront, allowing the host to overcommit storage. Which virtualization feature should the technician configure for the VM's virtual hard disk?

Accepted Answer

Thin provisioning. Thin provisioning allows the virtual hard disk to be created with a specified maximum size but only consumes physical storage on the host as data is written to the VM. This enables storage overcommitment, where the host can allocate more virtual disk space than physical storage exists, because the unused space is not pre-allocated. This matches the requirement to avoid consuming the entire allotment upfront while accommodating future growth.

Answer

Thick provisioning (eager zeroed)

Answer

Thick provisioning (lazy zeroed)

Answer

Deduplication

Question 9

A server administrator live-migrates a virtual machine (VM) from one hypervisor host to another within a cluster. After the migration, the VM powers on and the operating system boots, but it cannot communicate with any network resources. Other VMs on the destination host can communicate normally. The VM uses a virtual switch with a custom port group. Which of the following is the MOST likely cause of the network connectivity loss?

Accepted Answer

The destination host does not have the required virtual switch port group configured.. When a VM is live-migrated to a new hypervisor host, the virtual switch configuration must be identical on both hosts. If the destination host lacks the custom port group that the VM's virtual NIC is attached to, the VM will lose network connectivity because the virtual switch port cannot be created. Other VMs on the destination host work normally because they use port groups that are present on that host.

Answer

The VM's virtual NIC MAC address changed during migration.

Answer

The VM's IP address is statically assigned and conflicts with a device on the destination network.

Answer

The hypervisor version on the destination host is incompatible with the VM's virtual hardware version.

Question 10

A small office has 10 workstations connected to a single unmanaged switch, which is connected to a router that provides internet access. All workstations can access the internet. The manager wants to add a network printer so all workstations can print. The printer has an Ethernet port. Which of the following is the easiest way to connect the printer to the network?

Accepted Answer

Connect the printer to an available port on the switch.. Option B is correct because connecting the printer to an available port on the unmanaged switch places it on the same Layer 2 broadcast domain as the 10 workstations. Since the switch is already connected to the router for internet access, the printer will receive an IP address via DHCP from the router (or via link-local addressing if no DHCP server is present), making it immediately discoverable by all workstations on the network without requiring any additional configuration or dedicated host.

Answer

Connect the printer directly to a workstation's USB port and share it.

Answer

Connect the printer to the router's USB port.

Answer

Connect the printer to the WAN port of the router.
