NEW QUESTION # 160
You are asked to configure a redundant trunk group (RTG). Which two requirements would accomplish this task? (Choose two.)
Answer: A,D
NEW QUESTION # 161
You have configured the four EX Series switches with RSTP, as shown in the exhibit. You discover that whenever a link between switches goes up or down, the switches take longer than expected for RSTP to converge, using the default settings.
In this scenario, which action would solve the delay in RSTP convergence?
Answer: B
Explanation:
The exhibit shows the configuration of RSTP on EX-4, which has the command force-version stp.
This command forces the switch to use the legacy STP protocol instead of RSTP, even though the switch supports RSTP. This means that EX-4 will not be able to take advantage of the faster convergence and enhanced features of RSTP, such as edge ports, link type, and proposal/agreement sequence. The other switches in the network are likely to be running RSTP, as it is the default protocol for EX Series switches. Therefore, there will be a compatibility issue between EX-4 and the other switches, which will result in longer convergence times and suboptimal performance. The switch will also generate a warning message that says "Warning:
STP version mismatch with neighbor" when it receives a BPDU from a RSTP neighbor.
To solve this problem, the force-version command must be removed from EX-4, so that it can run RSTP natively and interoperate with the other switches in the network. This will enable faster convergence and better stability for the network topology. To remove the command, you can use the delete protocols rstp force-version command in configuration mode.
NEW QUESTION # 162
You have traffic for a video streaming application traversing a GRE tunnel in your network and users are reporting poor performance. Both ends of the tunnel are using the default settings for a gigabit Ethernet interface, but you observe excessive packet drops due to exceeding the MTU.
Which two steps would you take to improve connectivity for this application? (Choose two.)
Answer: A,D
Explanation:
The described symptom -- excessive packet drops specifically attributed to exceeding the MTU on a GRE tunnel carrying full-size video streaming traffic across default-MTU gigabit Ethernet interfaces -- is a direct consequence of the 24 bytes of GRE encapsulation overhead pushing packets that were already at or near the standard 1500-byte Ethernet MTU past the physical interface's transmission limit once the outer GRE and IP headers are added. The most durable fix is to proactively increase the physical member interfaces' MTU beyond the 1500-byte default -- to
1524 bytes or higher -- which provides sufficient headroom to absorb the full GRE encapsulation overhead without ever causing the fully encapsulated packet to exceed the interface's transmission capability, allowing full-size 1500-byte payloads to pass through the tunnel intact and without fragmentation or drops. As a complementary measure, configuring the clear-dont- fragment-bit option on the tunnel or member interfaces instructs Junos to clear the DF (don't fragment) bit on oversized packets rather than dropping them outright when they do exceed the available MTU, allowing the Packet Forwarding Engine to fragment and later reassemble the traffic instead of silently discarding it, which directly addresses the reported packet loss even under transient conditions. Simply raising the MTU only to 1500 bytes fails to account for the 24- byte GRE overhead and would not resolve the underlying oversize condition. Routing the tunnel over a higher-bandwidth link addresses potential congestion but does nothing to correct an MTU- based packet-size violation, which is the root cause explicitly identified in this scenario.
NEW QUESTION # 163
Which two statements correctly describe RSTP port roles? (Choose two.)
Answer: B,D
Explanation:
An RSTP topology contains ports that have specific roles:
The root port is responsible for forwarding data to the root bridge.
The alternate port is a standby port for the root port. When a root port goes down, the alternate port becomes the active root port.
The designated port forwards data to the downstream network segment or device.
The backup port is a backup port for the designated port. When a designated port goes down, the backup port becomes the active designated port and starts forwarding data.
NEW QUESTION # 164
Which two statements are correct about using firewall filters on EX Series switches? (Choose two.)
Answer: A,B
Explanation:
A is correct because you can deploy only stateless firewall filters on an EX Series switch. A stateless firewall filter is a filter that evaluates each packet individually based on the header information, such as source and destination addresses, protocol, and port numbers. A stateless firewall filter does not keep track of the state or context of a packet flow, such as the sequence number, flags, or session information. EX Series switches support only stateless firewall filters, which are also called access control lists (ACLs) or packet filters.
C is correct because you can apply firewall filters to both Layer 2 and Layer 3 traffic on an EX Series switch. Layer 2 traffic is traffic that is switched within a VLAN or a bridge domain, while Layer 3 traffic is traffic that is routed between VLANs or networks. EX Series switches support three types of firewall filters: port (Layer 2) firewall filters, VLAN firewall filters, and router (Layer
3) firewall filters. You can apply these filters to different interfaces and directions to control the traffic entering or exiting the switch.
