Which three types of booting are supported on servers? (Choose three.)
booting from internal storage
booting from LAN
booting from SAN
booting from WAN
booting from wireless - -booting from internal storage

- Which two characteristics apply to small office/home office (SOHO)
routers? (Choose two.)
They are more expensive than enterprise routers.
They are more reliable than enterprise routers.
They have a web-based administration interface.
They have integrated security functionality.
They perform intensive routing tasks. - -They have a web-based
administration interface.
They have integrated security functionality.
-
SOHO routers usually route between a small number of subnets, thereby
freeing resources to perform other networking tasks. SOHO routers integrate
functionalities provided by other networking devices, such as switches,
firewalls and DNS servers. Enterprise-grade routers are designed for very
high reliability and are more reliable than SOHO routers.
- Which two parameters can be used for metric calculations? (Choose two.)
IP Address
Hop count
Link Up/Downtime
Bandwidth
Default Route
Local Routes - -Hop count
Bandwidth
-
The metric calculation is a critical component of any routing protocol. The
routing protocol uses multiple factors to calculate the metric for a path, such
as Hop Count, Bandwidth, Delay, and Cost.
, - What is the network ID of the IPv6 address
2001:db8:deca:abce:45eb:27ff:feba:fa38/48?
2001::
2001:db8::
2001:db8:deca::
2001:db8:deca:abce:: - -2001:db8:deca::
-
Each hexadecimal character represents 4 binary bits. The first 12 characters
correspond to 48 bits. 2001:db8:deca:abce:: would have the /64 prefix,
2001:db8:: would have the /32 prefix, and 2001: would have the /16 prefix.
- In a wireless IEEE 802.11 implementation, what is the most secure option
to protect user traffic?
WEP
WPA
WPA2
WPA3 - -WPA3
-
Wi-Fi Protected Access 3 (WPA3) is a replacement of WPA2 and is the next
generation of wireless security standards that provides more resiliency to
network attacks.
- Which three elements are parts of an HTTP status line? (Choose three.)
protocol version
requested method
status code
status message
target URL - -protocol version
status code
status message
- Which task makes configuring network devices more efficient and reduces
errors?
compliance checks
data collection and telemetry
device provisioning
device software management - -device provisioning
-
Device provisioning configures network devices more efficiently, faster, and
with fewer errors because human interaction with each network device is
decreased.
, - Which type of cable is typically used to connect a core switch with a data
center switch, where bandwidth higher than 40 Gbps and low cost are
required?
Category 5e UTP
Category 6 UTP
multimode fiber
single-mode fiber - -multimode fiber
-
When connecting data center switches to the network core, high bandwidth
is required. Because data centers are typically at the same location as the
network core, multimode fiber cables are used to connect the switches
instead of single-mode fiber cables.
- Which two types of cables can be used to connect to the console port of a
Cisco router? (Choose two.)
crossover
rollover
serial
straight-through
USB - -rollover
USB
-
Cisco devices traditionally used rollover cables to connect to the console
port. Today, Cisco devices also offer a USB mini console port on the device.
- Which three fields are included in a TCP header? (Choose three.)
destination address
destination port
flags
frame check sequence
window size - -destination port
flags
window size
-
The destination port is the sequence of the called port (16 bits), window size
is the sequence of the data amount the destination can accept (16 bits), and
flags are control bits (9 bits).
- Which group of devices in a network receive IPv6 packets with the
destination address of ff05::2?
all IPv6 nodes on all the network segments within a site
all IPv6 nodes on the local network segments
all IPv6 routers on all the network segments within a site
all IPv6 routers on the local network segments
, all OSPFv3 routers on all the network segments within a site
all OSPFv3 routers on the local network segments - -all IPv6 routers on all
the network segments within a site
-
The hexadecimal digits "ff" in the IPv6 address prefix are an indication of a
multicast address. The fourth hexadecimal digit indicates the scope, with the
number five representing a site-local scope. The group ID of ::2 represents all
IPv6 routers.
- What are two characteristics of an anycast IPv6 address? (Choose two.) - -
It can be assigned to multiple nodes.
It is assigned from the unicast IPv6 address space.
-
Anycast IPv6 addresses are syntactically indistinguishable from unicast IPv6
addresses, and they do not have a dedicated prefix assigned. Anycast IPv6
addresses cannot be used by hosts, and they must not be used as the source
address of an IPv6 packet.
- On a Cisco switch, which two commands would you use to identify ports
that are configured as trunks? (Choose two.)
show interfaces status
show interfaces summary
show interfaces trunk
show ip interface brief
show vlan brief - -show interfaces status
show interfaces trunk
- Which fields does the 802.1Q header add to an Ethernet frame?
CRC
EtherType
preamble
VLAN ID - -VLAN ID
-
The 802.1Q header is a tag which includes VLAN ID. This header does not
include CRC, EtherType or preamble.
- Which three device types can benefit from Power over Ethernet (PoE)
connectivity? (Choose three.)
access switches
computers
IP cameras
VoIP phones
wireless access points - -IP cameras
VoIP phones
wireless access points
