CCNA 2 Flashcards
For which routes does the distance bgp 10 50 70 command set the administrative distance
For all bgp routes
Which effect of the terminal monitor command is true
It configures the device to log messages to the console
What interface command immediately removes the effect of an ACL
no ip access-group
Which prompt does a Cisco switch display when it is running in privileged exec mode?
Switch#
which two differences between distance-vector and link-state routing protocols are true:
Only distance-vector routing protocols send full routing table updates
Link-state routing protocols offer faster convergence than distance-vector protocols during network changes.
What is the purpose of traffic shaping?
control access to available bandwidth
to ensure that traffic conforms to the policies established for it
to regulate the flow of traffic in order to avoid congestion that can occur when the sent traffic exceeds the access speed of its remote, target interface
You are configuring an IP SLA ICMP Echo operation to troubleshoot a network connectivity issues. When do you enter an IP address to test the IP SLA?
When you define the ICMP Echo operation.
what is an ICMP Echo do?
The ICMP Echo operation measures end-to-end response time between a cisco router and any devices using IP so we have to enter an IP address to test.
Which two statements about 1000BASE-T UTP cable are true?
It uses four wire pairs
Both ends of the cable can transmit and receive simultaneously.
What is 1000BASE-T
Gigabit Ethernet on copper cables using four pairs of Cat 5 unshielded twisted pair to achieve the gigabit data rate.
What does the BASE stand for in 1000BASE-T
baseband signalling, which means that only Ethernet signals are carried on the medium.
Which two neighbor types are supported in BGP
External
Internal
What loopback address does IPV6 use
::1
What link-local address does ipv6 use
FE80::/10
What site-local address does ipv6 use
FEC0::/10
What global address does ipv6 use
2000::/3
What multicast address use
FF00::/8
True or false:
ipv6 mulitcast address identify a group of interfaces on different devices
True
Under which two circumstances is a switchport that is configured with PortFast BPDU guard error-disable
When the switch receives a BPDU from a connected switch
When a wireless access point running in bridge mode is connected to a switch
What are two advantages of static routing
It produces minimal CPU load
It allows the administrator to control the path of traffic
What BGP configuration do you need to apply to allow router traffice to flow normally
#router bgp 1 #no synchronization #neighbor 192.168.1.1 remote-as 1 #neighbor 192.168.2.1 remote-as 1 #neighbor 192.168.3.1 remote-as 5 no auto-summary
When should ebgp-multihop command be used
When configuring external BGP (eBGP) neighbors which are not directly connected.
What is the default TTL (Time to Live) of eBGP connection
1
Which command can you enter on a Cisco IOS device to enable a scheduled algorithm that directs lookup calls to multiple DNS hosts
ip name-server 192.168.10.14 192.168.10.15
Which API use HTTP messages to transfer data to applications residing on different host?
REST
Which two services can be provided by a wireless controller
providing authentication services to users
Managing interference in a dense network
Why does a root bridge choose one switch interface over another
The switch interface has a lower cost path and is chosen as the root bridge
Which value is included in the initial TCP syn message?
sequence number
Which two cable specifications can support 1-Gbps Ethernet?
Category 5e
Category 6
What two actions can be taken to secure the virtual terminal interface s on a router
Enter an access list and apply it to the virtual terminal interfaces using the access-class command Configure a virtual terminal password and login process
If you change the weight and distance parameters on a device with an established BGP neighbor which additional task must you perform to allow the two devices to continue exchanging routes?
Reset the BGP connections on the device
