NEW QUESTION # 43
You are bringing a new network online with three MX Series devices enabled for STP. No root bridge priority has been configured. Which statement is true in this scenario?
- A. The device with the lowest MAC address will be elected as the root bridge.
- B. The device with the highest numerical lo0 IP address will be elected as The bridge.
- C. The device with the lowest numerical lo0 IP address will be elected as the root bridge.
- D. The device with the highest MAC address will be elected as the root bridge.
Answer: A
Explanation:
https://supportportal.juniper.net/s/article/EX-Identify-the-Root-Bridge-in-a-Spanning-Tree-STP-network?language=en_US The root bridge in a spanning-tree network is the bridge with the smallest or the lowest bridge ID.
NEW QUESTION # 44
You are troubleshooting two OSPF routers that have an adjacency that remains in the ExStart state.
What would cause this problem?
- A. mismatched OSPF hello intervals on the OSPF interfaces
- B. mismatched authentication settings on the OSPF interfaces
- C. mismatched subnet settings on the OSPF interfaces
- D. mismatched MTU settings on the OSPF interfaces
Answer: D
Explanation:
https://www.cisco.com/c/en/us/support/docs/ip/open-shortest-path-first-ospf/13684-12.html#anc13 Neighbors Stuck in Exstart/Exchange State The problem occurs most frequently when you attempt to run OSPF between a Cisco router and another vendor router. The problem occurs when the maximum transmission unit (MTU) settings for neighboring router interfaces do not match. If the router with the higher MTU sends a packet larger that the MTU set on the neighboring router, the neighbor router ignores the packet. When this problem occurs, the output of the show ip ospf neighbor command displays output similar to what is shown in this figure.
A mismatched Maximum Transmission Unit (MTU) setting on OSPF interfaces can cause routers to get stuck in the ExStart state. OSPF requires that both sides of a link have the same MTU to form a full adjacency.

Referring to the exhibit, which two statements are correct? (Choose two.)
- A. Devices in AS 65512 will prefer ISP B for traffic destined to the 172.20.21.0/24 network.
- B. Devices in AS 65512 will prefer ISP A for traffic destined to the 172.20.21.0/24 network.
- C. Devices In AS 65512 will prefer ISP A for traffic destined to the 172.20.0.0/24 network.
- D. Devices In AS 65512 will prefer ISP B for traffic destined to the 172.20.0.0/24 network.
Answer: B,C
Explanation:
Local preference is a BGP attribute that dictates which path is preferred when multiple paths to the same destination are available. A higher local preference is preferred over a lower one. Since ISP A (AS 65501) is advertising a local preference of 100 and ISP B (AS 65502) is advertising a local preference of 200 to AS
65512, traffic from devices in AS 65512 will prefer the path via ISP B for all networks that ISP B advertises.
However, since ISP A advertises the 172.20.21.0/24 network and ISP B does not, traffic for 172.20.21.0/24 will go through ISP A. For the 172.20.0.0/24 network, which both ISPs advertise, devices in AS 65512 will prefer the path via ISP B due to the higher local preference.

NEW QUESTION # 52
What are three ways to configure IPv6 addresses in your network? (Choose three.)
- A. Configure your IPv6 addresses by assigning your router a prefix list.
- B. Configure your IPv6 addresses by setting up a DHCPv6 server.
- C. Configure your IPv6 addresses using stateless auto configuration.

NEW QUESTION # 53
Which two statements are correct about the way that BGP propagates routes by default? (Choose two.)
- A. A route learned by EBGP will not be re-advertised to IBGP peers.
- B. A route learned by EBGP will be re-advertised to IBGP peers.
- C. A route learned by IBGP will not be re-advertised lo IBGP peers.
- D. A route learned by IBGP will be re-advertised to IBGP peers.
Answer: B,C
Explanation:
By default, BGP will propagate routes learned from EBGP peers to other IBGP peers. However, due to the BGP split-horizon rule, routes learned from one IBGP peer are notre-advertised to another IBGP peer. This behavior is designed to prevent routing information loops within the same AS.
