The service provider has allocated a block of IPv4 addresses for your network 172.16.1.0 with a subnet mask of 25 bits. You company DHCP server was configured to use this block According to your company standards, the first available IP address is 172.16.1.130. The NOC has informed you that devices that use this block have partial connectivity. They communicate with other but cannot reach out side networks.
What is the reason for this behavior?

• A.The IP addresses that are distributed by the DHCP server are not on the same subnet as a default gateway
• B.The service provider, by mistake, allocated the RFC 1918 address.
• C.Because everything is configured correctly, the most likely cause is a DHCP server issue
• D.Because everything is configured correctly, the most likely cause is a connectivity issue with a service provider.

Refer to the exhibit. The NOC has informed you about a problem on a Gigabit Ethernet link between a newly installed CRS-1 that is running Cisco IOS XR Software and Cisco IOS router. These two routers cannot establish OSPF adjacency. When you connected to CRS1, you noticed that the Gigabit Ethernet interface MTU is 1500. You must adjust the interface MTU on the Cisco IOS router.
Which MTU should you configure on the Cisco IOS router interface to match the MTU that is configured on the Cisco IOS XR software?

• A.1500
• B.1486
• C.1488
• D.1486

Refer to the exhibit. Which commands append a prefix of 3.3.3.3/32 to prefix-set "test"?

• A.Prefix-set test Append 3.3.3.3/32 End-set
• B.Prefix-set test 1.1.1.1/32,2.2.2.2/32,3.3.3.3/32 End-set
• C.Prefix-set test 3.3.3.3/32 End-test

Refer to the exhibit. Referring to the output from the show command display, which four statements are correct? (Choose four)

• A.1.0.0.0 is a local prefix on the R2 router
• B.10.1.1.1 is an EBGP peer
• C.172 16 4 0/22 is an aggregated route and the summary-only option was used
• D.2.2.2.2/32 is a local prefix on the R2 router
• E.2.2.2.2 is an EBGP peer
• F.3.3.3.3 is an IBGP peer

Refer to the exhibit

The Cisco IOS Software platform PE1 has interface GigabitEthernet port 0/0 connected to the Cisco IOS XR software platform PE4 interface GigabitEthernet 0/4/0/2. OSPF cannot establish an adjacency. What is a possible solution to the problem?

• A.Change the interface configurations on both platforms to point network type
• B.Adjust the Cisco lOS XR Software hello and dead times to match Cisco IOS software
• C.Configure OSPF on each platform to ignore the interface MTU
• D.Explicitly configure the Cisco lOS XR Software interface to be active OSPF interface
