Which set of 2 4 GHz nonoverlapping wireless channels is standard in the United States?
The correct answer is D. Option D: channels 1, 6, and 11
A network engineer is installing an IPv6-only capable device. The client has requested that the device IP address be reachable only from the internal network. Which type of IPv6 address must the engineer assign?
The correct answer is B. Option B: unique local address
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead.
What is a requirement for nonoverlapping Wi-Fi channels?
The correct answer is B. Option B: discontinuous frequency ranges
A network engineer must implement an IPv6 configuration on the vlan 2000 interface to create a routable locally-unique unicast address that is blocked from being advertised to the internet. Which configuration must the engineer apply?
The correct answer is B. Option B: interface vlan 2000 ipv6 address fd00::1234:2343/64
Explanation
A VLAN creates a separate Layer 2 broadcast domain on switched infrastructure. OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. IPv6 uses 128-bit addresses and relies on Neighbor Discovery rather than ARP.
What are two characteristics of an SSID? (Choose two.)
The correct answer is B, E. Option B: It is at most 32 characters long Option E: It can be hidden or broadcast in a WLAN.
When a switch receives a frame for a known destination MAC address, how is the frame handled?
The correct answer is C. Option C: sent to the port identified for the known MAC address
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead.
What is the collapsed layer in collapsed core architectures?
The correct answer is A. Option A: Core and distribution
What is a characteristic of a SOHO network?
The correct answer is C. Option C: enables multiple users to share a single broadband connection
What is the role of disaggregation in controller-based networking?
The correct answer is A. Option A: It divides the control-plane and data-plane functions.
What is a function performed by a web server?
The correct answer is D. Option D: provide an application that is transmitted over HTTP
Refer to the exhibit. Site A was recently connected to site B over a new single-mode fiber path. Users at site A report intermittent connectivity issues with applications hosted at site B. What is the reason for the problem?
The correct answer is D. Option D: An incorrect type of transceiver has been inserted into a device on the link
Which protocol uses the SSL?
The correct answer is B. Option B: HTTPS
Why is UDP more suitable than TCP for applications that require low latency such as VoIP?
The correct answer is D. Option D: TCP sends an acknowledgement for every packet received: UDP operates without acknowledgments This option meets the real-time / low-latency performance requirement.
What are the two functions of SSIDs? (Choose two.)
The correct answer is A, E. Option A: uses the maximum of 32 alphanumeric characters Option E: broadcasts by default
Which two characteristics describe the access layer in a three-tier network architecture? (Choose two.)
The correct answer is B, D. Option B: physical connection point for a LAN printer Option D: layer at which a wireless access point connects to the wired network
Which PoE mode enables powered-devices detection and guarantees power when the device detected?
The correct answer is B. Option B: static
Refer to the exhibit. The router has been configured with a super net to accommodate the requirements for 380 users on a Subnet. The requirement already considers 30% future growth. Which configuration verifies the IP subnet on router R4?
The correct answer is D. Option D: Subnet: 10.7.54.0 Subnet mask: 255.255.254.0 Broadcast address: 10.7.55.255 Usable IP address range: 10.7.54.1 "" 10.7.55.254
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead.
Refer to the exhibit. Configurations for the switch and PCs are complete. Which configuration must be applied so that VLANs 2 and 3 communicate back and forth?
The correct answer is B. Option B: interface GigabitEthernet0/0.10 encapsulation dot1Q 3 ip address 10.10.2.10 255.255.254.0
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead.
How is RFC 1918 addressing used in a network?
The correct answer is C. Option C: They are used with NAT to preserve public IPv4 addresses.
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. NAT translates addresses between network domains, commonly conserving public IPv4 addresses.
Refer to the exhibit. What is a reason for poor performance on the network interface?
The correct answer is C. Option C: The cable connection between the two devices is faulty.
