CCNP Practice Test 7 — 10 Questions

Question 1

Which two statements about RESTCONF are true? (Choose two.)

Accepted Answer

RESTCONF uses HTTP methods like GET, PUT, POST, and DELETE to manipulate YANG data.. RESTCONF uses HTTP methods to access YANG-defined data on network devices. It supports both XML and JSON encoding. It does not use SSH or TLS natively for transport; it relies on HTTP over TLS (HTTPS) for security. The 'data' resource is the top-level resource for accessing YANG data stores. RESTCONF does not define its own data model; it uses YANG models.

Answer

RESTCONF supports only XML encoding for data.

Answer

RESTCONF uses SSH as the transport protocol.

Answer

RESTCONF defines its own data modeling language.

Question 2

Drag and drop each NETCONF operation on the left to its action on the right.

Accepted Answer

get: Retrieve running configuration and state data. Correct pairings: get retrieves running config and state data; get-config retrieves a specific datastore; edit-config modifies configuration; commit confirms a candidate configuration; lock prevents other sessions from modifying a datastore.

Question 3

Which three statements about YANG data models are true? (Choose three.)

Accepted Answer

YANG is used to model both configuration and operational state data.. YANG is a data modeling language used to model configuration and state data for network devices. It can define both configuration data (which is writable) and operational state data (which is read-only). YANG models can be augmented using the 'augment' statement to add nodes to an existing model without modifying it. YANG does not define transport protocols; it is used with protocols like NETCONF and RESTCONF. The 'leaf' statement defines a single, scalar data node, not a list.

Answer

YANG defines the transport protocol for data exchange.

Answer

The 'leaf' statement in YANG defines a list of key-value pairs.

Question 4

Drag and drop each RESTCONF method on the left to its equivalent NETCONF operation on the right.

Accepted Answer

GET: get-config (retrieves data). Correct pairings: GET retrieves data (like get-config); POST creates a resource (like edit-config with operation create); PUT replaces a resource (like edit-config with operation replace); PATCH partially updates (like edit-config with operation merge); DELETE removes a resource (like edit-config with operation delete).

Question 5

Given the following configuration on a Cisco IOS-XE device:

router ospf 1
 network 10.0.0.0 0.255.255.255 area 0
!
interface GigabitEthernet0/0
 ip address 10.1.1.1 255.255.255.0
 ip ospf cost 10
!
interface GigabitEthernet0/1
 ip address 10.2.2.1 255.255.255.0
!

Which statement is true about OSPF operation?

Accepted Answer

GigabitEthernet0/0 will have an OSPF cost of 10, and GigabitEthernet0/1 will have a default cost based on its bandwidth.. The 'ip ospf cost' command overrides the default cost calculation based on bandwidth. The network command matches both interfaces because they fall under 10.0.0.0/8.

Answer

Both interfaces will have an OSPF cost of 10.

Answer

Both interfaces will have the same OSPF cost because they are in the same area.

Answer

OSPF will not run on either interface because the network command uses a wildcard mask of 0.255.255.255.

Question 6

Which BGP attribute is preferred when it has the lowest value?

Accepted Answer

MED (Multi-Exit Discriminator). BGP uses multiple attributes in its path selection algorithm. The weight attribute is Cisco-specific and is preferred with the highest value. The local preference is also preferred with the highest value. The MED (Multi-Exit Discriminator) is preferred with the lowest value.

Answer

Weight

Answer

Local Preference

Answer

AS Path Length

Question 7

Examine the following EIGRP configuration on a Cisco IOS-XE device:

router eigrp 100
 network 10.0.0.0 0.255.255.255
 passive-interface default
 no passive-interface GigabitEthernet0/0
!
interface GigabitEthernet0/0
 ip address 10.1.1.1 255.255.255.0
!
interface GigabitEthernet0/1
 ip address 10.2.2.1 255.255.255.0

Which statement is true?

Accepted Answer

EIGRP will form an adjacency only on GigabitEthernet0/0.. The 'passive-interface default' command sets all interfaces as passive, meaning they do not send or receive EIGRP hellos. The 'no passive-interface' command overrides this for specific interfaces.

Answer

EIGRP will form adjacencies on both GigabitEthernet0/0 and GigabitEthernet0/1.

Answer

EIGRP will not form any adjacencies because the network command does not match the interface subnets.

Answer

EIGRP will form adjacencies on all interfaces except those with 'passive-interface' configured.

Question 8

A network administrator is troubleshooting a BGP routing issue where routes from an eBGP neighbor are not being installed in the routing table. The 'show ip bgp' output shows the routes are received but not valid. What is the most likely cause?

Accepted Answer

The next-hop IP address is not reachable.. For a BGP route to be considered valid and installed in the routing table, the next-hop IP address must be reachable via an IGP or a static route. If the next hop is not reachable, the route will appear in the 'show ip bgp' output but will be marked as not valid (often with a 'r' for received but not valid). This is the most common cause when routes are received from an eBGP neighbor but not installed.

Answer

The AS-path contains the local AS number.

Answer

BGP synchronization is enabled.

Answer

The maximum-prefix limit has been exceeded.

Question 9

A network engineer is troubleshooting a problem where Cisco DNA Center is not receiving syslog messages from a critical core switch. The switch is configured to send syslog to the DNA Center's IP address. The engineer checks the DNA Center syslog collector and finds that it is enabled. What should the engineer check next?

Accepted Answer

Verify that the syslog port (UDP 514) is not blocked by a firewall or ACL.. Cisco DNA Center's syslog collector listens on specific ports (default UDP 514). If the switch is configured to send syslog but DNA Center is not receiving it, a common issue is that the syslog port is blocked by a firewall or ACL between the switch and DNA Center. The engineer should verify network connectivity and port accessibility.

Answer

Check if the syslog messages are in the correct format.

Answer

Ensure that the switch is in the Inventory and managed by DNA Center.

Answer

Restart the syslog collector service on DNA Center.

Question 10

Drag and drop the steps of NBAR2 application recognition and classification steps into the correct order, from first to last.

Accepted Answer

Enable ip nbar protocol-discovery on interface. NBAR2 configuration begins by enabling the protocol discovery, then creating a class map to match the application, a policy map to mark traffic, applying it to the interface, and verifying the classification. NBAR2 uses deep packet inspection to identify applications.
