An administrator has two 1 Gbps links between two switches and wants to increase throughput and provide redundancy. The switches support LACP. What should the administrator configure?

Enable RSTP on both switches and leave the links as separate routed ports.

Leave both links as separate access ports in the same VLAN.

Configure both links as a single aggregated Ethernet interface using LACP.

Configure one link as an access port and the other as a trunk port.

A network engineer is troubleshooting a connectivity issue and examines an Ethernet frame. The frame contains a source MAC address of 00:11:22:33:44:55 and a destination MAC of ff:ff:ff:ff:ff:ff. What is the purpose of this frame?

It is a broadcast frame intended for all hosts on the local network segment.

It is a frame with an invalid destination that will be dropped by the switch.

It is a multicast frame sent to a specific group of hosts.

It is a unicast frame sent to a single specific host.

An administrator configures a link aggregation group (LAG) with three 1 Gbps links between two switches. What is the primary benefit of this configuration?

It allows each physical link to carry traffic for a different VLAN.

It eliminates the need for spanning tree protocol on the switches.

It creates three separate broadcast domains.

It provides up to 3 Gbps of aggregate bandwidth and link redundancy.

What is the main benefit of link aggregation (e.g., LAG or LACP) on Ethernet switches?

It allows multiple VLANs to share the same IP address

It eliminates the need for Spanning Tree Protocol

It increases the available bandwidth by combining multiple physical links into one logical link

It reduces the number of MAC addresses needed on the network

Ethernet Networking JN0-105 Practice Questions (Page 2)

Part of the Networking Fundamentals domain, which makes up ~24% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~8–14 in this domain), expect 1–1 from this objective — we provide 22 practice questions to prepare you well beyond it.
