Question #16
You are asked to connect an IP phone and a user computer using the same interface on an EX Series switch. The traffic from the computer does not use a VLAN tag, whereas the traffic from the IP phone uses a VLAN tag.
Which feature enables the interface to receive both types of traffic?
Which feature enables the interface to receive both types of traffic?
- Anative VLAN
- BDHCP snooping
- CMAC limiting
- Dvoice VLAN
Correct Answer:
D
D
GPT-4o - Answer
Voice VLAN is the go-to feature for configuring an interface on an EX Series switch to handle traffic from both an IP phone and a computer simultaneously. The interface treats computer data as untagged, aligning with the access port settings for the data VLAN, and uses the voice VLAN setting to appropriately manage tagged traffic from the IP phone. This setup not only effectively segregates traffic types but also facilitates quality of service (QoS) for voice communications, ensuring higher priority and better performance for voice traffic over IP.
Question #17
The ISP1.inet.0 route table has currently no routes in it.
What will happen when you commit the configuration shown on the exhibit?
Question #18
Your ISP is announcing a default route to both R1 and R2. You want your network routers to forward all Internet traffic through the R1 device.
Which BGP attribute would you use?
Question #19
Which two BGP attributes must be supported by all BGP implementations and must be included in every update? (Choose two.)
- AAS path
- BMED
- Cnext hop
- Dcommunity
Correct Answer:
AC
AC
GPT-4o - Answer
The AS path and next hop attributes are fundamental to the BGP routing protocol. Every BGP update must include the AS path, which lists the Autonomous Systems a route has passed through, aiding in loop prevention and path selection. Similarly, the next hop attribute, specifying the IP address for forwarding packets to the route’s destination, is essential for guiding data through the correct network paths. Both are classified as well-known mandatory attributes, indispensable for consistent routing behavior and interoperability among systems in diverse networks.
Question #20
Your BGP neighbors, one in the USA and one in France, are not establishing a connection with each other.
