NO.41 How does a layer 2 switch populate its bridge table?

It stores the protocol number of frames traversing the network.

It stores both the source and destination MAC addresses of frames traversing the network.

It stores the destination MAC address of frames traversing the network.

It stores the source MAC address of frames traversing the network.

NO.42 In the context of protocol-independent routing, what is the main difference between static and generated routes?

Static routes require manual configuration, while generated routes are created dynamically.

Static routes are used for load balancing, while generated routes are not.

Generated routes support summarization, while static routes do not.

Generated routes are manually configured, while static routes are automatically created.

NO.43 What protocol and port does BGP use for control plane communication?

protocol TCP, port 179

protocol UDP, port 179

protocol TCP, port 159

protocol UDP, port 159

NO.44 When configuring High Availability components, which of the following practices are recommended? (Choose two)

Regularly update firmware to non-recommended versions.

Ensure physical redundancy of critical components.

Use a single path for data and control traffic.

Implement regular testing of failover mechanisms.

NO.45 You are configuring OSPF in your network as shown in the exhibit. R1 has been configured with interface metrics. All other links in the network are using the default interface metric.
In this scenario, which OSPF interface on R1 will be preferred when routing traffic between R1 and R5?

ge-0/0/0

ge-0/0/3

ge-0/0/1

ge-0/0/2

NO.46 In Junos, which command is used to display the status of all interfaces?

show interfaces terse

show vlan brief

show interfaces descriptions

show ethernet-switching table

NO.47 How can OSPF be configured to prefer one route over another?

By setting a higher cost on the preferred route.

By configuring route redistribution.

By adjusting interface bandwidth.

By setting a lower cost on the preferred route.

NO.48 Which statement is correct about the OSPF link-state database?

Each router within the same area must maintain a unique copy of the link-state database.

Each router within the same area must maintain an identical copy of the link-state database.

Each router within the OSPF domain must maintain a unique copy of the link-state database.

Each router within the OSPF domain must maintain an identical copy of the link-state database.

NO.49 When troubleshooting issues with static routes, what is a key factor to check first?

If the routing table has enough memory

The correctness of the specified next-hop addresses

The speed of the router’s CPU

The number of aggregate routes configured

NO.50 What is the function of the ‘Weight’ attribute in BGP, and where is it used in the route selection process?

It is used to prioritize routes received from different EBGP peers and is considered before the AS_PATH attribute.

It determines the stability of a route and is checked after the Local Preference attribute.

It is a Cisco-specific attribute used to prefer paths from one BGP speaker over another, evaluated before the Local Preference.

It is used to balance load among multiple links and is considered after the MED attribute.

NO.51 Referring to the exhibit, which two statements are correct about the IP fabric? (Choose two.)

Only traffic between pods must traverse the super spine devices.

All traffic must traverse the super spine devices.

This is a three-stage IP fabric.

This is a five-stage fabric.

NO.52 What is the main advantage of using an Overlay Network in a data center?

It simplifies physical network design by allowing multiple virtual topologies over it.

It replaces the need for physical network infrastructure.

It offers higher physical bandwidth capacity.

It provides direct Internet access to applications.

NO.53 VLANs help in reducing which of the following? (Choose two)

Collision domains

Broadcast domains

Routing complexity

Encryption requirements

NO.54 What is the main advantage of using MACsec?

It increases the speed of the network.

It provides Layer 2 encryption for data confidentiality and integrity.

It creates multiple virtual networks over a single physical infrastructure.

It allows for the use of longer cable runs.

NO.55 Why is EVPN often used in conjunction with VXLAN in modern data centers?

To enable direct Internet access for applications.

For providing Layer 2 connectivity over a Layer 3 fabric.

To increase the physical bandwidth of the underlying network.

To physically separate different customer environments.

NO.56 What does VXLAN stand for in the context of EVPN/VXLAN?

Virtual Extensible VLAN

Virtualized Ethernet VPN

Very Extended Virtual LAN

Virtual X-Series LAN

NO.57 Fill in the blank: In BGP, the ___________ attribute is used to influence the best path selection process.

MED (Metric or Multi-Exit Discriminator)

AS_PATH

Local Preference

Community

NO.58 Referring to the exhibit, which statement is correct?

The ge-0/0/0 interface has been explicitly assigned to a VLAN named default.

The default VLAN is a user defined VLAN name.

The asterisk indicates that the interface is active.

The ge-0/0/12 interfaces is an access port.
